The Place Of Coca Leaf In The Living World

(from) Chapter 11

The History of Coca (1901)

(in) The Coca Leaf Papers (2014)

By Bill Drake

 In previous posts I have presented various excerpts from Dr. Mortimer’s excellent book, which not only contains a wealth of highly relevant information but illustrates the often-acknowledged but poorly understood fact that human beings keep re-discovering the insights of those gone before them, treating such “discoveries” as new knowledge.

Dr. Mortimer’s book also vividly demonstrates how easily knowledge is lost, or deliberately set aside, in pursuit of the agenda of the times.

It is impossible to estimate how many millions of people are suffering and dying right this moment because the agenda of our times has demonized Coca Leaf as part of a worldwide set of political and economic agendas conceived in ignorance and maintained with malice regarding the place of natural medicines in treating and healing diseases that arise naturally and diseases that are caused by external agents, almost always in pursuit of profit.

In both cases, access to pure, natural Coca Leaf for self-treatment would undermine the political and economic agendas of powerful groups, and so we suffer and die, by the millions each year, in servitude to these cruel and heartless sub-humans.

In my continuing protest against this overwhelming flood of power and money that is drowning the planet, I offer this excerpt from a chapter in “The History of Coca” in which Dr. Mortimer explains the place of Coca in the natural world, and the processes by which its magical properties occur. Perhaps you, the reader, will be one more voice raised against the denial of this potent natural medicine to all those suffering, dying people whose lives could be mended and saved simply by having access to this miraculous leaf. 

The Place Of The Coca Leaf In The Living World

In the Coca leaf, as indeed in all plants, the cell wall is made up of cellulose, a carbohydrate substance allied to starch, with the formula xC6H10O5. The material for the building of this substance, it is presumed, is secreted by the cell contents or by a conversion of protoplasm under the influence of nitrogen. This product is deposited particle by particle inside of the wall already formed. Accompanying this growth there may occur certain changes in the physical properties of the cell as the wall takes in new substances, such as silica and various salts, or as there is an elaboration and deposit of gum, pectose and lignin. Each living cell contains a viscid fluid, of extremely complex chemical composition – the protoplasm – a layer of which is in contact with the cell wall and connected by bridles with a central mass in which the nucleus containing the nucleolus is embedded. The protoplasm does not fill the whole cavity of the cell, but there is a large space filled with the watery sap.

The sap carries in solution certain sugars, together with glycogen and two varieties of glucose, and such organic acids  and coloring matters as may already have been elaborated.  Where metabolism is active, certain crystallizable nitrogenous bodies, as asparagin, leucin and tyrosin, with salts of potassium and sodium, are found, while in the vacuole there may be starch grains and some crystals of calcium oxalate. The  protoplasm is chemically made up of proteids, of which two groups may be distinguished in plants. The first embracing  the plastin, such as forms the frame work of the cell, and the second the peptones of the seeds, and the globulins found in the buds and in young shoots. These proteids all consist of carbon, hydrogen, nitrogen, oxygen, and sulphur, while plastin also contains phosphorus. In active growing cells the proteids are present in a quantity, which gradually diminishes as the cell becomes older, leaving the plastin as the organized proteid wall of the cell, while the globulins and peptones remain unorganized. The whole constructive metabolism of the plant is toward the manufacture of this protoplasm, the chemical decomposition and conversion of which liberates the energy which continues cell life.

In certain cells of the plant associated with the protoplasm, and presumably of a similar chemical composition, are little corpuscles, which contain the chlorophyl constituting the green coloring matter of plants, a substance which from its chemical construction and physiological function may have some important influence on the alkaloid formation in the Coca leaf. In these bodies the chlorophyl is held in an oily medium, which exudes in viscid drops when the granules are treated with dilute acids or steam. Although no iron has been found in these bodies by analysis, it is known that chlorophyl cannot be developed without the presence of iron in the soil. Gautier, from an alcoholic extract, calculated the formula C19H22N2O3, and called attention to the similarity between this and that of bilirubin, C16H18N203 – the primary pigment forming the golden red color of the human bile, which possibly may be allied to the red corpuscles of the blood. Chlorophyl, while commonly only formed under appropriate conditions of light and heat, may in some cases be produced in complete darkness, in a suitable temperature. Thus if a seed be made to germinate in the dark, the seedling will be not green, but pale yellow, and the plant is anӕmic, or is termed etiolated, though corpuscles are present, which, under appropriate conditions, will give rise to chlorophyll.

It has been found that etiolated plants become green more readily in diffused light than in bright sunshine. The process of chlorophyll formation neither commences directly when an etiolated plant is exposed to light, nor ceases entirely when a green plant is placed in darkness, but the action continues through what has been termed photo-chemical induction. From experiments to determine the relative efficacy of different rays of the spectrum it has been found that in light of low intensity seedlings turn green more rapidly under yellow rays, next under green, then under red, and less rapidly under blue. In intense light the green formation is quicker under blue than under yellow, while under the latter condition decomposition is more rapid.

The function of chlorophyl is to break up carbonic acid, releasing oxygen, and converting the carbon into storage food for the tissues, the first visible stage of which constructive metabolism is the formation of starch. The activity of this property may be regarded as extremely powerful when it is considered that in order to reduce carbonic acid artificially it requires the extraordinary temperature of 1300° C. (2372° F.). In the leaf this action takes place under the influence of appropriate light and heat from the sun in the ordinary  temperature of 10°-30° C. (50°-86° F.). Plants which do not contain chlorophyl – as fungi – obtain their supply of carbon through more complex compounds in union with hydrogen.

Perhaps we are too apt to regard plants as chiefly cellulose – carbohydrates, and water, without considering the importance of their nitrogenous elements, for though these latter substances may be present in relatively small proportion, they are as essential in the formation of plant tissue as in animal structures. The carbohydrates of plants include starch, sugars, gums, and inulin. The starch or an allied substance, as has been shown, being elaborated by the chlorophyl granules, or in those parts of the plant where these bodies do not exist, by special corpuscles in the protoplasm, termed amyloplasts, which closely resemble the chlorophyl bodies. In the first instance the change is more simple and under the  influence of light, in the latter light is not directly essential and the process is more complex, the starch formation beginning with intermediate substances – as asparagin, or glucose,  by conversion of the sugars in the cell sap.

Just as in the human organism, assimilation in plant tissue cannot take place except through solution, so the stored up starch is of no immediate service until it is rendered soluble.  In other words, it must be prepared in a way analogous to the digestion of food in animal tissues. This is done by the action of certain ferments manufactured by the protoplasm. These do not directly enter into the upbuilding of tissue themselves, but induce the change in the substance upon which they act. Chiefly by a process of hydration, in which several molecules of water are added, the insoluble bodies are rendered soluble, and are so carried in solution to various portions of the plant. Here they are rearranged as insoluble starch, to serve as the common storage tissue for sustenance. Thus it will be seen how very similar are the processes of assimilation in plants and animals, a marked characteristic between both being that the same elementary chemical substances are necessary in the upbuilding of their tissues, and  particularly that activity is absent where assimilable nitrogen is not present.

Several organic acids occur in plant cells, either free or combined, which are probably products of destructive metabolism, either from the oxidation of carbohydrates or from the decomposition of proteids. Liebig regarded the highly oxidized acids – especially oxalic, as being the first products of constructive metabolism, which, by gradual reduction, formed carbohydrates and fats, in support of which he referred to the fact that as fruits ripen they become less sour, which he interpreted to mean that the acid is converted into sugar. The probability, however, is that oxalic acid is the product of destructive metabolism, and is the final stage of excretion from which alkaloids are produced, while it is significant, when considering the Coca products, that acids may by decomposition be formed from proteid or may by oxidation be converted into other acids.

Oxalic acid is very commonly found in the leaf cells combined with potassium or calcium. It is present in the cells of  the Coca leaf as little crystalline cubes or prisms. Malic acid, citric acid, and tartaric acid are familiar as the products of various fruits. Tannic acid is chiefly found as the astringent property of various barks. Often a variety of this acid is characteristic of the plant and associated with its alkaloid. This is the case with the tannic acid described by Niemann in his separation of cocaine, which is intimately related to  the alkaloids of the Coca leaf, just as quinine is combined with quinic acid and morphine with meconic acid. It has been suggested that the yield of alkaloid from the Coca leaf is greater in the presence of a large proportion of tannic acid.

Tannin is formed in the destructive metabolism of the protoplasm, as a glucoside product intermediate between the carbohydrate and the purely aromatic bodies, such as benzoic and cinnamic acids, which are formed from the oxidative decomposition of the glucosides. In addition to these are found fatty oils, associated with the substances of the cell, and essential oils, to which the fragrance of the flower or plant is due, and which are secreted in special walled cells.  The resins are found as crude resins, balsams – a mixture of  resin and ethereal oil with an aromatic acid, and gum resins  – a mixture of gum, resin and ethereal oil. The ethereal oils include a great number of substances with varying chemical composition, having no apparent constructive use to the tissues, but, like the alkaloids, regarded merely as waste. Some  of these products serve by their unpleasant properties to repel animals and insects, while others serve to attract insects and thus contribute to the fertilization of the flower, so all these  bodies may be of some relative use.

The proteids of the plant are supposed to be produced  from some non-nitrogenous substance – possibly formic aldehyde – by a combination formed from the absorbed nitrates, sulphates and phosphates, in union with one of the organic acids, particularly oxalic. The change being from the less complex compound to a highly nitrogenous organic substance, termed an amide, which, with the non-nitrogenous substance and sulphur, unite to form the proteid. The amides are crystallizable nitrogenous substances, built up synthetically, or formed by the breaking down of certain compounds. They  are similar to some of the final decomposition products found in the animal body. Belonging to this group of bodies is xanthin, which Kossel supposed to be directly derived from nuclein, from the nucleus of the plant cell. But in whatever manner the amides are formed, it is believed they are ultimately used in the construction of proteid, and although this substance is produced in all parts of the plant, it is found more abundant in the cells containing chlorophyl. Proteids are found to gradually increase from the roots toward the leaves, where they are most abundant. This would seem to indicate that the leaf is the especial organ in which proteid formation takes place, and it is in this portion of the Coca plant that the excreted alkaloids are found most abundantly.

According to Schützenberger, the proteid structures are composed of ureids, derivatives of carbamide, and Grimaux considers they are broken by hydrolysis into carbonic acid, ammoniac and amidic acids, thus placing them in near relation with uric acid, which also gives by hydrolysis, carbonic  acid, ammoniac acid and glycocol. In animal tissues the last product of excrementition is carbamide – or uric acid, while the compounds from which proteids are formed in plants have been shown to be amides. It has been shown in the laboratory that the chemical products from the breaking down of proteids are also amides, with which carbonic acid and oxalic acid are nearly always formed. The presence of hippuric acid in the urine of herbivorous animals, the indol and the skatol found in the products of pancreatic digestion (Salkowski), together with the tyrosin nearly always present in the animal body, has led to the supposition that aromatic groups may also be constituents of the proteid molecule.

All of this is of the greatest interest in the study of alkaloid production in connection with the fact, which has been proved, that when a plant does not receive nitrogen from outside it will not part with the amount of that element previously contained – in other words, the nitrogenous excreta will not be thrown off. Boussingault thought the higher plants flourished best when supplied with nitrogen in the form of nitrates, though Lehmann has found that many plants flourish better when supplied with ammonia salts than when supplied with nitrates, and this has been well marked in the case of the tobacco plant.

Nitric acid may be absorbed by a plant in the form of any of its salts which can diffuse into the tissues, the most common bases being soda, potash, lime, magnesia and ammonia. The formation of this acid, attendant upon the electric conditions of the atmosphere, may be one source of increase of vigor to the native soil of the Coca plant, where the entire region of the Montaña is so subject to frequent electrical storms. Then Coca flourishes best in soils rich in humus, and various observers have remarked that nitrogen is best fixed in such a soil. An interesting point in connection with which is that the ammonia supplied to the soil by decomposition of nitrogenous substances is converted into nitrous, and this into nitric acid, by a process termed nitrification, occasioned by the presence of certain bacteria in the soil to which this property is attributed. Proof of this was determined by chloroforming a section of nitrifying earth and finding that the process on that area ceased. The absorption of nitrogen by the Coca plant and the development of  proteids is closely associated with the nitrogenous excreta from the plant, and the consequent production of alkaloids which we are attempting to trace.

The nitrogen of the soil, however induced, is transferred by oxidation into what has been termed the reduced nitrogen of amides which, in combination with carbohydrates, under appropriate conditions forms proteids, in which oxalic acid is an indirect product. Several observers consider the leaves as active in this process, because the nitrogenous compounds are found to accumulate in the leaf until their full development, when they decrease. This is illustrated by the fact that in autumn, when new proteids are not necessary to matured leaves, it accumulates in the protoplasm, from which it is transferred to the stem, to be stored up as a food for the following season’s growth.

It has been found that the nitrates, passing from the roots as calcium nitrate, are changed in the leaves by the chlorophyl in the presence of light with the production of calcium oxalate, while nitric acid is set free, and conversely, in darkness the nitrates are permitted to accumulate. This change is influenced by the presence of oxalic acid, which, even in small quantities, is capable of decomposing the most dilute solutions of calcium nitrate. The free nitric acid in combination with a carbohydrate forms the protein molecule, while setting free carbonic acid and water.

Cellulose, which we have seen is formed from protoplasm, is dependent upon the appropriate conversion of the nitrogenous proteid. When this formation is active, large amounts of carbohydrates are required to form anew the protein molecule of the protoplasm, and the nitrogenous element is utilized. When there is an insufficiency of carbohydrate material the relative amount of nitrogen increases because the conditions are not favorable for its utilization in the production of proteids, and this excess of nitrogen is converted into amides, which are stored up. When the carbohydrate supply to the plant is scanty in amount this reserve store of amides is consumed, just the same as the reserve fat would be consumed in the animal structure under similar conditions.

The relation between the normal use of nitrogen in plants is analogous to its influence in animal structure, while the final products in both cases are similar, the distinction being chiefly one in the method of chemical conversion and excretion due to the difference in organic function. Thus, although urea and uric acid are not formed in plants, the final products of both animals and plants are closely allied. We  see this especially in the alkaloids caffeine and theobromine, which are almost identical with uric acid, so much so that Haig considers that a dose of caffeine is equivalent to introducing into the system an equal amount of uric acid.

There are numerous examples, not only in medicinal substances, but in the more familiar vegetables and fruits, which illustrate the possibilities of change due to cultivation. The Siberian rhododendron varies its properties from stimulant to a narcotic or cathartic, in accordance with its location of  growth. Aconite, assafoetida, cinchona, digitalis, opium and rhubarb are all examples which show the influence of soil  and cultivation. Indeed similar effects are to be seen everywhere about us, certain characteristics being prominently brought forth by stimulating different parts of the organism, so that ultimately distinct varieties are constituted.  The poisonous Persian almond has thus become the luscious peach. The starchy qualities of the potato are concentrated in its increased tuber, and certain poisonous mushrooms have become edible. The quality of the flour from wheat is influenced by locality and cultivation. The tomato, cabbage, celery, asparagus, are all familiar examples which emphasize the possibility of shaping nature’s wild luxuriance to man’s cultured necessity.

The chemical elements which are taken up by a plant vary considerably with the conditions of environment, and the influence of light in freeing acid in the leaf has been indicated. These conditions necessarily modify the constituents of the plant. When metabolism is effected certain changes take place in the tissues, with the formation of substances which may be undesirable to the plant, yet may be medicinally serviceable. Such a change occurs in the sprouts of potatoes stored in the dark, when the poisonous base solania is formed, which under normal conditions of growth is not present in the plant. A familiar example of change due to environment is exhibited in the grape, which may contain a varying proportion of acid, sugar and salts in accordance with the soil, climate and conditions of its cultivation, nor are these variations merely slight, for they are sufficient to generate in the wine made from the fruit entirely different tastes and properties.

The Basic Nature Of Alkaloids

In view of these facts, it seems creditable to suppose that by suitable processes of cultivation the output of alkaloids may be influenced in plants, and such experiments have already been extensively carried out in connection with the production of quinine. When attention was directed to the scientific cultivation of cinchona in the East, it was remarked that when manured with highly nitrogenous compounds the yield of alkaloid was greatly increased. This is paralleled by the fact that when an animal consumes a large quantity of nitrogenous food the output of urea and uric acid is greater.

Alkaloids are regarded as waste products because they cannot enter into the constructive metabolism of the plant, though they are not directly excreted, but are stored away where they will not enter the circulation, and may be soon shed, as in the leaf or bark. Though, as indicating their possible utility, it has been shown experimentally that plants are capable of taking up nitrogenous compounds, such as urea, uric acid, leucin, tyrosin, or glycocol, when supplied to their roots. In some recent experiments carried out at the botanical laboratory of Columbia University, I found that plant metabolism was materially hastened under the stimulus of cocaine.

The influence of light in the formation of alkaloids has already been shown. Tropical plants which produce these substances in abundance in their native state often yield but small quantities when grown in hot houses, indicating that a too intense light is unfavorable, probably in stimulating a too rapid action of the chlorophyl, together with a decomposition of the organic acid. Some years ago the botanist. Dr.  Louis Errera, of Brussels, found that the young leaves of certain plants yielded more abundant alkaloid than those that were mature. Following this suggestion, Dr. Greshoif is said to have found that young Coca leaves yield nearly double the amount of alkaloid over that contained in old leaves gathered at the same time. In tea plantations the youngest leaves are gathered, but it has always been customary to collect the mature leaves of the Coca plant, and these have usually been found to yield the greatest amount of alkaloid. The probability is that the amount of alkaloid present in the Coca leaf is not so much influenced by maturity as it is by the period of its gathering.

As regards the temperature at which growth progresses most favorably, Martins  has compared each plant to a thermometer, the zero point of which is the minimum temperature at which its life is possible. Thus, the Coca shrub in its native state will support a range from 18° C. (64.4° F.) to  30° C. (86° F.), an influence of temperature which is governed by the proportion of water contained in the plant. It has been found, from experiments of cultivation, that Coca will flourish in a temperature considerably higher than that which was originally supposed bearable, though the alkaloidal yield is less than that grown more temperately. The life process of any plant, however, may be exalted as the temperature rises above its zero point, though only continuing to rise until a certain height is reached, at which it ceases entirely. In the cold, plants may undergo a similar hibernation as do certain animals when metabolism is lessened,  though long-continued cold is fatal, and frost is always so absolutely to Coca. The influence of temperature on metabolism tends to alter the relations between the volume of carbonic acid given off and the amount of oxygen absorbed.  Under a mean temperature these relations are equal, while in a lower temperature more oxygen is absorbed in proportion to the carbonic acid given off, and oxygen exhalation ceases entirely below a certain degree.

A relatively large proportion of water in a plant determines its susceptibility to climatic conditions. Thus freezing not only breaks the delicate parenchymatous tissues, but alters the chemical constitution of the cells, while too high a temperature may prove destructive through a coagulation of the albumen. The appearance of plants killed by high or low temperature being similar. Roots are stimulated to curve to their source of moisture, and their power for absorption is more active in a high than in a low temperature, but as absorption is influenced by the transpiration of the plant, it is less active in a moist atmosphere, unless the metabolic processes of the plant occasions a higher temperature than the surrounding air. Such activity would be increased by the heat of the soil about the roots, and is probably manifest in the Coca plant through the peculiar soil of the Montaña.

The elevation at which a plant grows has an influence upon the absorption by the leaf. Thus it has been observed that while a slight increase in the carbonic acid gas contained in the air is favorable to growth, a considerable increase is prejudicial, while an increase or diminution of atmospheric pressure materially influences plant life. In some tropical countries Coca will grow at the level of the sea, provided there is an equable temperature and requisite humidity. Although in Peru Coca flourishes side by side with the best  coffee, it will not thrive at the elevations where the coffee plant is commonly grown in either the East or West Indies. In Java, where experiments have been made in cultivating Coca, it has been stated that there is no perceptible difference in the alkaloidal yield due to the influence of elevation, while in the best cocals of Peru it is considered that the higher the altitude at which Coca can be grown the greater will be the alkaloidal yield. This is possibly effected by similar influences to that governing the aromatic properties developed in  the coffee bean, which have been found more abundant when coffee is grown at an elevation, yet without danger of frost.  This may be attributed to slower growth and a consequent  deposit of nitrogenous principles instead of their being all consumed through a rapid metabolism.

It is therefore evident that as these several physical conditions have a marked bearing upon the life history of all plants, the more limited the range for any of these processes in any particular plant, the more it will be influenced. Thus in an altitude too high, the leaf of the Coca plant is smaller and only one harvest is possible within the year, while in the lower regions where the temperature exceeds 20° C. (68° F.)  vegetation may be exuberant, but the quality of leaf is impaired. The electrical conditions of the atmosphere, it has been shown, have an important bearing upon the development of Coca, through the influence of the gases set free in the atmosphere and the possible slight increase of nitric acid carried to the soil.

It was thought by Martins that the mosses and lichens which are found upon the Coca shrubs were detrimental to the plant through favoring too great humidity. In the light of our knowledge on the development of alkaloids, however, it has seemed to me that here is an opportunity for very extended experimentation, as may be inferred from a reference to the alkaloidal production of cinchona. At first efforts were made to free the cinchona trees from the lichens and mosses which naturally formed upon them; but it was discovered accidentally that those portions of the trees which nature had covered in this manner yielded an increased amount of alkaloid. When cinchona plantations were started in Java, experiments made upon the result of this discovery prompted a systematic covering of the trunks of  the trees artificially with moss, which was bound about them to the height from which the bark would be stripped. At  first very great pains was taken to collect just an appropriate kind of moss, which it was supposed from its association with the tree in its native home would be essential, but later experiments proved that any form of covering which protected the bark from light increased this alkaloidal yield. So  that to-day this process, which is known as “mossing,” is one of the most important in the cultivation and development of cinchona.

A Source Of Profound Confusion

The chief interest of Coca to the commercial world has centered upon its possibilities in the production of the one alkaloid, cocaine, instead of a more general economic use of the leaf. Because of this, much confusion of terms has resulted, for chemists have designated the amount of alkaloids obtained from the leaf as cocaine, although they have qualified their statement by saying that a portion of this is un-  crystallizable. Numerous experiments have been conducted to determine the relative yield of cocaine from the different varieties of Coca, and when uncrystallizable alkaloids have been found the leaf has been condemned for chemical uses.  It will thus be appreciated how a great amount of error has been generated and continued. The Bolivian or Huanuco variety has been found to yield the largest percentage of crystallizable alkaloid, while the Peruvian or Truxillo variety, though yielding nearly as much total alkaloid, affords a less percentage that is crystallizable, the Bolivian Coca being set apart for the use of the chemists to the exclusion of the Peruvian variety, which is richest in aromatic principles and best suited for medicinal purposes. As a matter of fact, the Peruvian Coca is the plant sought for by the native users.

There is not only a difference in the yield of alkaloid from different varieties of Coca, but also a difference in the yield from plants of one variety from the same cocal, and it would seem possible by selection and propagation of the better plants to obtain a high percentage of alkaloid. At present there is no effort in the native home of Coca toward the production of alkaloid in the leaf through any artificial means.  Regarding the quality of alkaloid that has been found in the different plants, the Peruvian variety has been found to contain equal proportions of crystallizable and uncrystallizable alkaloid, while the Bolivian variety contains alkaloids the greater amount of which are crystallizable cocaine. Plants which are grown in conservatory, even with the greatest care, yield but a small percentage of alkaloid, of which, however, the uncrystallizable alkaloid seems more constant while the relative amount of cocaine is diminished. In leaves grown at Kew .44 percent, of alkaloid was obtained, of which .1 percent, was crystallizable. From experiments of Mr. G. Peppe, of Renchi, Bengal, upon leaves obtained from plants imported from Paris, it was found that leaves dried in the sun yielded .53 per cent, of alkaloid, of which .23 per cent was  uncrystallizable. The same leaves dried in the shade on cloth for twenty hours, then rolled by hand, after the manner in which Chinese tea is treated, then cured for two and a half hours and dried over a charcoal fire and packed in close tins, yielded .58 per cent, of alkaloid, of which .17 per cent, was  uncrystallizable.

It is probable that each variety of Coca has a particular range of altitude at which it may be best cultivated. The Bolivian variety is grown at a higher altitude than Peruvian Coca, while the Novo Granatense variety has even been found to thrive at the level of the sea. Among Coca, as among the cinchona certain varieties yield a large proportion of total alkaloids, of which only a small amount is crystallizable. The Cinchona succirubra yields a large amount of mixed alkaloids, but a small amount of quinine, while Cinchona Calisaya yields a smaller amount of mixed alkaloids and a large amount of crystallizable quinine. A few authors who have referred to the alkaloidal yield of Coca leaves have casually remarked that the plants grown in the shade produce an increased amount above those grown in the  sun, which would appear to be paralleled by the formation of chlorophyl and the production of proteids, both of which have so important a bearing upon the metabolism of the plant and the final nitrogenous excretion.

This subject is one full of interest, yet so intricate that it has not been possible for me to elaborate the suggestions here set forth in time to embody my investigation in the present writing, though I hope to present the result of my research at no very distant date. It would seem that sufficient has been shown, however, to indicate the possibility of modifying plant metabolism under appropriate conditions of culture so as to influence the development of the alkaloidal excreta. The comparisons between plant and animal life may have proved of sufficient interest to enlist attention to the higher physiology in which will be traced the action of Coca.

Manufacturing Of Cocaine: Then And Now

Courageous soldiers on patrol protecting our freedom

Like far too many aspects of modern life the production of Cocaine has gotten cruder, and more toxic over the years. Legal small-scale high quality Coca Leaf production is the only viable alternative to failed suppression strategies that have resulted in the government-sanctioned poisoning of millions of people. If you ask “who benefits” from the War on Cocaine there is only one answer – the government bureaucracies who have managed to create millions of secure jobs for themselves worldwide. All they have to do is keep managing the media, keep the legislators under control, keep their Cartel partners happy, and they can laugh all the way to their fat, happy pensions. The trail of millions of bloody bodies they leave in their wake doesn’t bother them one bit.

For a detailed look at the crude, toxic methods and materials used by the drug cartels in producing the Cocaine that sells on the streets of the US and Europe, check out http://www.deamuseum.org/ccp/coca/production-distribution.html

Yes that’s a DEA website, with full instructions on how the bad guys make Cocaine. DEA likes to show off and mock the primitive methods used by the cartels. As if they aren’t knuckle-draggers themselves.

Highly trained Special Forces attack the enemy hand-to-leaf

Also let’s remember that the cocaine cartels are forced into those crude jungle labs by the DEA drug Nazis, where all they have access to for the most part is primitive equipment and materials. But big joke – that’s all anyone really needs to produce a white (well, off-white really) powder ready for snorting by people who for the most part could care less about purity and quality as long as they get the buzz they’re seeking.

In my opinion poisoned Cocaine is an avoidable tragedy of monstrous proportions created and maintained by world governments that has resulted in the destruction of millions of lives. The enforcers of narcotics laws worldwide are fully complicit in the slaughter, and in spite of their self-righteous bullshit they know it, and the sickest of them get sexually aroused when they think about “enforcing the law”. 

But all that is 100% about Cocaine – not Coca leaf.

The world of Mama Coca wasn’t always this way. Although readers of this blog know that I have no particular interest in Cocaine, since its relevance to health and healing is minimal when compared with the pure, natural Coca Leaf from which it is derived, it may be of interest to readers to discover that today’s Cocaine bears only a chemical resemblance to the Cocaine that was being produced in the 1800’s by pharmacy labs and even by doctors themselves for their patients.

Quality and purity were the primary concerns and since there weren’t any drug Nazis busting down doors Cocaine labs could focus on those higher concerns rather than having to huddle in the jungle and drink kerosene fumes for lunch while brewing “who gives a shit” Cocaine.

So here I’m offering a chapter on Cocaine manufacturing from “The History Of Coca” by Dr. William Golden Mortimer (1901) which is available in its entirety my E-Book The Coca Leaf Papers.

Fair warning; what follows here is pretty detailed – not a 3-minute quick read.

CHAPTER X: THE PRODUCTS OF THE COCA LEAF

“Nor Coca only useful art at Home,
A famous Merchandize thou art become;
A thousand Paci and Vicugni groan
Yearly beneath thy Loads, and for thy sake alone
The spacious World’s to us by Commerce Known.” –Cowley.

Search For The Secrets Of The Coca Leaf

Of all the problems in the study of Coca the search for the force producing qualities of the leaf is the most profound. Science, ever alert to trace with exactitude the secrets of Nature, has struggled in vain to isolate and explain this hidden source of energy. But so cleverly are the atoms associated which go to build up the molecules of power in this marvelous leaf, that though the chemist through the delicacy of analysis has from time to time placed these atoms in differing groups and thus often given to the world some new combination, the one sought element of pent-up endurance inherent in Coca has remained concealed. It is like the secret of life – though known to be broadly dependent on certain principles which may readily be explained, the knowledge of the one essential element remains as great a secret as before research began.

Though all the accounts of travelers had directed attention to the peculiar qualities of Coca in sustaining strength, at the period when the first knowledge of this leaf reached Europe chemistry was not sufficiently advanced to admit of an exact analysis of plant life. Indeed, science met with little encouragement when the great powers were engrossed in political preferment, and it was not until the latter part of the eighteenth century that an impetus seemed given to research after Lavoisier had laid the foundation for modern chemistry. Though he lost his life on the guillotine through the whirligig of political fate during the French Revolution, just as he was at the height of his labors, a new interest was established and the work of the French chemists became active.

Humboldt was then making his extensive explorations through South America, collecting data which was to serve as a basis of research during many subsequent years. Cuvier, the anatomist, was advancing his theories on the classification of animals; Fraunhofer had established a means for studying the heavenly bodies through the spectrum, while chemical electricity had progressed from the experiments of Volta to the electromagnet of Ampere.

The method for expressing chemical equations, such as are now shown by those symbolic letters and figures which appear to the uninitiated as so many hieroglyphics, was not understood until Dalton, in 1808, had perfected his law of proportions. This was an important advance in chemical knowledge, for from it was built up the sign language which in a chemical formula expresses not only the symbol of each element, but tells the chemist the relative proportion of the combining atoms.

These fundamental facts are of interest as bearing upon the chemical history of the Coca leaf, while the combining nature of atoms has suggested an interesting theory that the physiological action of a chemical medicine is influenced by its molecular weight. This has been a matter of discussion among physiological chemists for years, and was suggested by Blake as long ago as 1841 and since by Rabuteau. Thus an element of a fixed atomic weight may have special reference to the muscular system, while another of different weight may act upon the nervous tissue – qualities which are fulfilled in the action of the several Coca bases.

Early Clues & Misdirections

Boerhaave may be said to have been the father of the present system of organic chemistry in the early part of the eighteenth century. So important were his teachings held that his works were translated into most modern languages. Although his attempts at analysis of living things attracted a wide interest, they could be in no manner exact, because the fundamental elements entering into the composition of all organic structure – carbon, hydrogen, oxygen and nitrogen – had not then been determined. Yet so skilled were his observations, even under limited opportunities, that many of his conclusions have not since been refuted in the light of improved methods. Perhaps the earliest hint upon alkaloids was that made by this scientist when he referred to the bitter principle in the juices from chewing Coca as yielding “vital strength” and a “veritable nutritive.”

It was reserved for Liebig some hundred years later to perfect the science of living structures, and to show there was not that exact separation between the chemistry of the organic and inorganic world that had previously been supposed. Following the teachings of this master mind, many compounds were constructed in the laboratory synthetically, and urea was thus produced in 1828 by Woehler, whose name is associated with the early investigators upon cocaine. Research upon the chemistry of organic bodies was now active. In England the work of Davy upon soils and crops, and the investigations of Darwin, unfolded in his theory of the origin of species, gave a new meaning to the study of organic life.

It was but a natural outcome of this spirit for research that turned the attention of explorers to South America, which had remained practically a new world since its discovery. Here were to be found innumerable strange plants indigenous to a country where everything was marvelous when viewed with the comparative light of the older world. In the height of this interest, the suggestive hints of naturalists and travelers were incentives to further the investigations of the European chemists. The writings of Cieza, Monardes, Acosta, Garcilasso and a host of others upon the wonderful qualities of the Coca leaf, stimulated a desire to solve its tradition of ages and prove its qualities by the test of science.

It is surprising to now look back over three centuries and recall these early authors, to consider under what conditions they wrote, and to read with what enthusiasm and exactness they gave expression to the knowledge they had gained from an observation of the novel customs about them. Thus the Jesuit father, Blas Valera, speaking of the hidden energy of Coca, wrote: “It may be gathered how powerful the Cuca is in its effect on the laborer, from the fact that the Indians who use it become stronger and much more satisfied and work all day without eating.”

It was not until after Coca had been botanically described by Jussieu, and classified by Lamarck, that its chemical investigation approached thoroughness. The researches of Bergmann and Black upon “fixed air” – as carbonic acid was then termed, the discovery of hydrogen by Cavendish, of nitrogen by Rutherford and of oxygen by Priestley, each following upon the other in quick succession in the latter half of the eighteenth century, displayed the great activity of chemistry at that period. Although no result was then arrived at in the investigations upon Coca, the spirit of the time was eminently toward exactitude, and this was displayed in many endeavors to trace to a chemical principle the potency of the Coca leaf.

Attention was very naturally directed to the method in which Coca was used, and the llipta which was employed with the leaves in chewing was looked upon as having some decided influence. Dr. Unanue, who has written much concerning the customs of the Indians, was one of the first to suggest that possibly this alkaline addition to the leaf developed some new property to which the qualities of Coca might be attributed, while Humboldt, as elsewhere referred to, through an error of observation considered this added lime as the supposed property of endurance.

Stevenson, in 1825, described the action of the llipta as altering the insipid taste of the leaves so as to render them sweet, and in 1827 Poeppig expressed the opinion that there was a volatile constituent in the Coca leaf which exposure to the air completely destroys.

Attention had now been directed to the isolation of alkaloids from plants, and during the first quarter of the nineteenth century several active principles were thus obtained and the possibility of tracing the hidden properties of Coca through analysis was suggested. Von Tschudi, when engaged in his extended explorations through Peru, became so impressed with the qualities of Coca that he advised Mr. Pizzi, Director of the Laboratory Botica y Drogueria Boliviana at La Paz, to examine the leaves, which resulted in the discovery of a supposed alkaloid, but when on his return to Germany this body was shown to Woehler, it was found to be merely plaster of paris, the result of some careless manipulation.

Dr. Weddell, in 1850, after a prolonged personal experience in the Andes with the sustaining effects of Coca, pronounced it as yielding a stimulant action differing from that of all other excitants. This influence both he and other observers supposed might be due to the presence of theine, the active principle of tea, which had shortly before been discovered, and was then exciting considerable discussion. With this idea in view, Coca leaves were examined, and, though this substance was not found, there was obtained a peculiar body, soluble in alcohol, insoluble in ether, very bitter, and incapable of crystallization, and a tannin was obtained to which was attributed the virtues of Coca.

About this same period there was found in the leaves a peculiar volatile resinous matter of powerful odor, and two years later, from a distillation of the dry residue of an aqueous extract of Coca, an oily liquor of a smoky odor was separated together with a sublimate of small needle-like crystals, which was named “Erythroxyline,” after the family of which Coca is a species. So each new investigator made a little progress, and in 1857 positive results were very nearly reached through the following process: An extract of Coca was made with acidulated alcohol, the alcohol was expelled, and the solution rendered alkaline by carbonate of soda. Upon extracting this with ether, an oily body of alkaline reaction was obtained without bitter taste, which on application to the tongue produced a slight numbness. The reaction of platinum chloride yielded with the acid solution a yellowish precipitate, soluble in water. From a distillate of the leaves with alkali there was remarked a disagreeable, strongly ammoniacal odor. Subsequently a peculiar bitter principle, extractive and chlorophyl, a substance presumed to be analogous to theine, and a salt of lime was found.

These negative findings led some to assert that Coca was inert and its properties legendary, but more careful observation has shown the true difficulty was an inability to secure appropriately preserved leaves for examination. This was made evident through an essay upon Coca by an eminent Italian neurologist, from experiences while a resident of Peru, when a host of physiological evidence emphasized the powerful nature of Coca, wholly apart from any mere delusions of fancy or superstition. The weight of facts presented proved sufficiently forcible not only to stimulate the waning spirit for scientific inquiry, but to awaken a widespread popular regard in what was now generally accepted as a plant of phenomenal nature.

In the height of this interest Dr. Scherzer, who accompanied the Austrian frigate Novara on the expedition to South America, opportunely brought home specimens of Coca leaves from Peru. These were sent to Professor Woehler of Gottingen for analysis, who entrusted their examination to his assistant, Dr. Albert Niemann, who is regarded as the discoverer of the alkaloid cocaine. Thus this chemist entered upon the investigation of Coca not a mere accidental way, but with an understanding of the seriousness of his research and its probable importance.

The “Aha” Moment That Led To Cocaine

Niemann exhausted coarsely ground Coca leaves with eighty-five per cent, alcohol containing one-fiftieth of sulphuric acid; the percolate was treated with milk of lime and neutralized by sulphuric acid. The alcohol was then recovered by distillation, leaving a syrupy mass, from which resin was separated by water. The liquid then treated by carbonate of soda to precipitate alkaloid emitted an odor reminding of nicotine, and deposited a substance which was extracted by repeatedly shaking with ether, in which it was dissolved, and from which the ether was recovered by distillation. There was found an alkaloid present in proportion of about one-quarter of one percent, which was named “Cocaine” after the parent plant, and the chemical formula C32H20NO8, according to the old notation, was given it. Mechanically mixed with its crystals there was a yellowish-brown matter of disagreeable narcotic odor, which could not be removed with animal charcoal or recrystallization, and was only separated by repeated washings with alcohol.

Pure cocaine, as described by this investigator, is in colorless transparent prisms, inodorous, soluble in seven hundred and four parts of water at 120 C. (53.60 F.), more readily soluble in alcohol, and freely so in ether. Its solutions have an alkaline reaction, a bitter taste, promote the flow of saliva and leave a peculiar numbness, followed by a sense of cold when applied to the tongue. At 980 C. (208.40 F.) the crystals fuse and congeal again into a transparent mass, from which crystals gradually form. Heated above the fusing point, the body is discolored and decomposes, running up the sides of the vessel. When fused upon platinum the crystals burn with a bright flame, leaving a charcoal which burns with difficulty. The alkaloid is readily soluble in all dilute acids forming salts of a more bitter taste than the uncombined cocaine. It absorbs hydrochloric acid gas, fuses and congeals to a grayish white transparent mass which crystallizes after some days. The crystals from its solution are long, tender and radiating.

Besides cocaine, there was found in the alcoholic tincture precipitated by milk of lime a snowy white granular mass. This fused at 700 C. (1580 F.), was slowly soluble in hot alcohol, more readily so in ether, and was not acted on by solutions of acids or alkalies. This substance was named Coca wax and given the empirical formula C66H66O4.

Upon distilling one hundred grammes of leaves, a slightly turbid distillate was obtained, which when redistilled with chloride of sodium, yielded white globular masses lighter than water and having the peculiar tea-like odor of Coca.

In the dark red filtrate from which the cocaine had been precipitated by carbonate of soda there was found after suitable treatment a Coca tannic acid to which the formula C14H18O8 has been given. This latter result, it will be remembered, was as far as Wackenroder’s investigations had gone in 1853.

The atomic weight of the amorphous compound determined from the double salt with chloride of gold, was found to equal 283, and when crystallized from hot water 280, or from alcohol 288. On heating this double salt benzoic acid was sublimed from it, which was recorded as the first observation of this nature from any known alkaloid.

Chemists Go Crazy Over The “Magic Bullet”

Following this research, the late Professor John M. Maisch of Philadelphia verified the several results. The small percentage of nitrogen announced in the original formula suggested that possibly cocaine was a decomposition compound, while the nicotine odor was thought to result from a nitrogenous body or another alkaloid. To determine this, the liquor and precipitate which had been obtained by carbonate of soda were distilled over a sand bath. A syrupy liquid was left, from which the alkaloid was separated by ether, while from the distillate was collected a resin-like mass of an acrid taste, having a narcotic odor, soon lost on exposure to a damp atmosphere, while the mass became acid and was now rendered easily soluble in water and alcohol. Whether or not this principle was nitrogenous this investigator left undecided.

Continuing the same line of research as that of Niemann, and following the suggestions of Maisch, William Lossen of Gottingen carried out an extended inquiry as to the nature of cocaine, and established its formula C17H21NO4, in accordance with the new notation. In examining its composition he found by heating it with hydrochloric acid that it was split up into benzoic acid and another body, thereby confirming the observation which had been made concerning this sublimation from the double salt of chloride of gold and cocaine. This new base he named “ecgonine,” from the Greek for son or descendant.

The breaking down of cocaine was subsequently shown due to hydration, by saponifying it with baryta, and also with water alone. The first change being into benzoyl-ecgonine, followed by a sublimation of benzoic acid, while from the syrupy residue the ecgonine may be separated by repeated washings with alcohol and precipitation with ether. The crystals being only dried with great difficulty.

Ecgonine, C9H15NO3, crystallizes over sulphuric acid in sheaves. It has a slight bitter-sweet taste, is readily soluble in water, less so in absolute alcohol, and insoluble in ether. Heated to 1980, it melts, decomposes and becomes brown. It forms salts with the acids, most of which crystallize with difficulty. With alkalies, it forms crystallizable combinations soluble in water and alcohol. In aqueous solutions the hydrochloride yields no precipitate with alkalies. Chloride of platinum in presence of much alcohol gives an orange yellow precipitate, chloride of mercury throwing down a yellow precipitate under the same conditions.

The unstable nature of cocaine in the presence of acids has suggested their avoidance in its preparation, plain water being considered preferable. In this process Coca leaves are digested several times at 1400 to 1760, the infusions united, precipitated by acetate of lead, and filtered. The lead is removed by the addition of sulphate of soda, and the liquor concentrated in a water bath. Carbonate of soda is then added, and the whole shaken with ether to dissolve the alkaloid, when the ether may be recovered by distillation.

In his researches Lossen also described the liquid alkaloid that had been hinted at by Gaedcke in 1855, and subsequently noticed by Niemann and Maisch, which, at the suggestion of Woehler, who was associated in this investigation, was termed ”hygrine”, from vypos – liquid, to which the formula C12H13N was given. This was obtained by saturating the slightly alkaline mother liquor from which cocaine had been extracted with carbonate of soda and repeatedly washing with ether. Evaporation of the ethereal extract left a thick yellow oil of high boiling point with a strong alkaline reaction.

Hygrine thus found is described as very volatile, distilling alone between 140° and 230° F. It is slightly soluble in water, and more readily so in alcohol, chloroform and ether, not in caustic soda, but readily in dilute hydrochloric acid. Its taste is burning and it has a peculiar odor similar to trimethylamine or quinoline. The oxalate and muriate are crystallizable, but very deliquescent.

With chloride of platinum, hygrine gives a flocculent amorphous precipitate which decomposes on heating. Bi-chloride of mercury gives an opalescence, due to the formation of minute oily drops.

Thus far there had been found in Coca leaves a crystallizable compound of unstable composition – cocaine; a second base which was only to be crystallized with difficulty – ecgonine; an intermediate compound – benzoyl-ecgonine; and an oily volatile liquid of peculiar odor – hygrine; together with Coca-tannic acid, and a wax-like body. Meantime, considerable was done in a physiological way in experimenting with the new alkaloids, though little decided progress was made during the following twenty years, until 1884, when the use of cocaine in local anӕsthesia was announced. The importance of this application occasioned an increased activity of investigation regarding the Coca products. This interest tended to make our knowledge of the alkaloids more exact, as well as to enrich our understanding of those inherent sustaining properties of Coca which have for past ages excited wonder.

Entrepreneurs Capitalize On The Discovery

In the early days of the cocaine industry some manufacturers asserted that the several associate substances found in Coca leaves were decomposition products, developed by changes taking place in deteriorating leaves or arising during the process of obtaining the one alkaloid. The great demand for cocaine and the high price it commanded generated an apparent unwillingness on the part of manufacturers to admit the possible presence in Coca of any other principle than cocaine. Processes innumerable were devised to force the greatest yield of alkaloid from the leaves, and some of the earlier specimens of the salt placed upon the market were more or less an uncertain mixture, dirty white in color and having a nicotine-like odor. This was defended as a peculiarity of the substance, the therapeutic action of which was asserted to be identical with cocaine, even though the appearance was not so elegant as the purer crystals. An endeavor to purify the salt by studying its sources of decomposition resulted in the separation of several important alkaloids.

The intermediate base benzoyl-ecgonine C16H19N04, was described as a by-product of the manufacture of cocaine, and it has been shown may be also obtained by the evaporation of cocaine solutions. It has been prepared by heating cocaine with from ten to twenty parts of water in a sealed tube at 90° to 95° C, with occasional shaking until a clear solution is obtained. This is extracted with ether to remove all traces of undecomposed cocaine, and then concentrated on a water bath and crystallized over sulphuric acid. The crystals form as opaque prisms or needles, sparingly soluble in cold water, more readily so in hot water, acids, alkalies and alcohol, while insoluble in ether. It melts at 90° to 92° C, then solidifies, and again melts at about 192° C. The taste is bitter, its solutions are slightly acid, becoming neutral after recrystallization. The hydrochloride, at first of a syrupy consistency, forms tabular crystals which are freely soluble in absolute alcohol. Mayer’s reagent produces a white, curdy precipitate; iodine in potassium iodide, a kermes brown precipitate; chloride of gold, a bright yellow precipitate, soluble in warm water and alcohol.

It will be recalled that Maclagan, Niemann and Maisch had each alluded to an uncrystallizable residue in their processes of extraction, and an effort was made to definitely determine its true quality. But just as cocaine was at first regarded as the only alkaloid, so this amorphous substance was studied as a whole instead of being regarded as a mixture of bases. Coca leaves, it was asserted, contained a crystallizable cocaine and an uncrystallizable cocaine. The latter product has been named cocaicine, cocainoidine and cocaminey and is still the subject of investigation.

The relative amount of this non-crystallizable body left in the mother liquor after the precipitation of cocaine varies greatly and is wholly dependent upon the kind of leaves used, or the processes to which they are subjected. The color of various specimens varies from dark yellow to dark brown, while the consistence is from that of a syrupy liquid to a sticky, tenacious solid, which, after spontaneous evaporation, may form short, fine crystals. The odor, while recalling nicotine, is more aromatic and less pungent; the taste bitter and aromatic. This body is of alkaline reaction, soluble in alcohol, ether, benzole, chloroform, petroleum ether, acetic acid, etc., and of varying solubility in water, according to its consistence. On gently heating it becomes quite fluid. It is very soluble in dilute acids, with which it forms non-crystalline salts, all of which dissolve readily in water. Dissolved in rectified spirit and treated with animal charcoal or acetate of lead, to precipitate the coloring matter, a pale yellow, sticky, non-crystalline body is obtained, which will not form crystals, even after standing for months. Solutions of the substance in alcohol, repeatedly precipitated by ammonia, yield a nearly white non-crystalline flocculent body, which is very hygroscopic, the original odor and taste remaining, no matter how often the purifying process is repeated. Evaporated at gentle heat, the solutions darken, and if evaporated to dryness the substance becomes insoluble in water. The precipitation with permanganate of potash is brownish, which, on heating, yields an odor of bitter almonds; 5 c.c. of a solution 1-1000 reduces 20 to 40 drops of a permanganate solution of the same strength.

Professor Stockman, of Edinburgh, made an interesting study of these mixed bases, which he originally supposed to be a solution of ordinary crystalline cocaine in hygrine, basing his conclusions on the physiological action and chemical relations. As he stated, cocaine is extremely soluble in hygrine, and once solution has occurred it is practically impossible to separate the two bodies, as they are both soluble in the same menstrua and are both precipitated by the same reagents.

This is also the case with the salts of these bodies, though not to the same extent, the presence of hygrine rendering any such samples of the salt hygroscopic, as well as imparting the peculiar nicotine-like odor of hygrine. Subsequent investigation, however, has convinced this physiologist that the substance he experimented with was cocamine dissolved in hygrine, together with some benzoyl-ecgonine.

Thus it will be seen that the earlier conclusions regarding the Coca products were erroneous from imperfect knowledge. With the increasing usefulness of cocaine this confusion is a serious matter, because these mis-statements of the chemists and physiologists are often still quoted as authoritative. So positive were some of these earlier opinions that even after physiological proof showed the unmistakable presence of associate alkaloids with cocaine they were asserted, from interested motives, to be poisonous contaminations. In the face of this the result of physiological experimentation with the various Coca bases indicate that they are all more mild than cocaine, from which they differ markedly in physiological action. Dr. Bignon, Professor of Chemistry at the University of Lima, Peru, who from position and opportunities may be regarded as a competent authority upon Coca, long since asserted, when grouping the alkaloids of Coca in two classes, that the crystalline body is inodorous, while the non-crystalline has a peculiar odor and is weaker in action and less poisonous than the crystallizable cocaine.

Where Most “Magic Bullet” Hunters Went Astray

The wholly different action of cocaine therapeutically from the Coca leaves of the Andean, or the more exact scientific preservations of Coca such as exhibited in the preparations of M. Mariani – which fully represents the action of recent Peruvian Coca, clearly indicates the presence of certain important principles in Coca, the properties of which are sufficiently distinct to markedly effect physiological action in a manner different from any one of its alkaloids. Happily we are now learning more definitely through research and experimentation, and these earlier errors are being corrected.

The diametrically opposite findings of investigators of known repute indicate that these inharmonious conclusions were not wholly the result of carelessness nor prejudice. Just as Coca experimented with by one observer repeated the traditional influence, or in some other instance proved inert, so the chemists found the result of their labors at variance. Much of this confusion was cleared away when the botanists explained that there are several varieties of Coca. Those qualities which had formerly been attributed to superstitious belief, or which when reluctantly accepted as possibly present in an extremely fugitive form which was lost through volatility, were shown to be dependent upon the variety as much as upon the quality of the Coca leaf employed in the process of manufacture.

Cocamine, C19H23N04, was originally studied in the alkaloids obtained from the small leaf variety of Coca by Hesse. It was regarded by Liebermann as identical with a base which he described as y-isatropyl-cocaine and afterward termed a truxilline, because supposedly found only in the Truxillo variety of Coca.

The research leading to these conclusions provoked bitter controversy between these two investigators. It has since been determined that cocamine is of the same empirical composition as cocaine, though weaker in anaesthetic action. It is a natural product of several varieties of Coca, particularly of that grown in Java. From hydrolysis by mineral acids cocamine yields cocaic, iso-cocaic and homo-iso-cocaic acids, while from its isomeride there is formed in a similar way alpha-isotropic or beta-truxillic acid. Both cocaic and iso-cocaic acids yield cinnamic acid and other products on distillation. Subsequently a similar body was prepared synthetically from ecgonine and cinnamic anhydride, and named cinnamyl-cocaine. It forms large colorless crystals, melts at 1200, is almost insoluble in water, and readily soluble in alcohol and ether. This body has been proved to occur naturally in Coca leaves from various sources, being present in some specimens as high as 0.5 per cent.

Thus it will be seen there has been much discussion and uncertainty upon the Coca products, particularly so as to those of an oily nature, originally designated as hygrine and the amorphous substances previously described under various titles.

It is the opinion of Hesse that hygrine is a product of decomposition of one of the Coca bases, and does not occur in fresh Coca leaves; in support of which he asserted that while dilute acid solutions of hygrine have a strongly marked blue florescence which is characteristic, this reaction is not shown when fresh leaves are first operated upon. But as this reaction develops gradually, he inferred that hygrine was formed by the decomposition of amorphous cocaine, from the solution of which it could be separated by ammonia and caustic soda as a colorless oil having the odor of quinoline. In fact, he considered the oil thus obtained a homologue of quinoline, possibly a tri-methyl-quinoline.

Another observer, while experimenting with the alkaloids of Coca by means of their platinum salts, obtained an oily base, exceedingly bitter and differing in odor and solubility from that which had been described by Lessen, but which was presumably identical with the amorphous products, cocaicine and cocainiodine, and Hesse concluded there might really be two oily bases in amorphous cocaine, one found in the benzoyl compounds of the broad leaf variety and one in the cinnamyl compounds of the Novo Granatense variety, in both cases associated with cocamine and another base, which he named cocrylamine. Liebermann, on the other hand, considers hygrine a combination of two liquid oxygenated bases which may be separated by fractional distillation. One – C8H15NO, an isomeride of tropine, with a boiling point 1930 to 195°, the other, C14H24N20, not distilling under ordinary pressure without decomposition, while still other experimenters from distilling barium ecgonate obtained a volatile oily liquid which strongly resembles hygrine. Merck has shown this body yields, on decomposition, methylamine, from which it has been inferred that it is identical with tropine, and hence closely allied to atropine. With this fact in view it was presumed the dilating property of cocaine upon the pupil was due to hygrine, but this has been proved not to be the case.

The assertion that hygrine is never present in Coca leaves, but is merely a decomposition product in the manufacture of cocaine, lends an added interest to the research of Dr. Kusby upon fresh Coca leaves made while he was at Bolivia. From repeated examinations he found a certain yield of alkaloids, while specimens of the same leaves sent to the United States yielded from treatment by the same process less than half the percentage of alkaloid that he had obtained. This prompted him to search for the possible source of error, and it was found that after all the cocaine was eliminated there was still a decided alkaloidal precipitate. From this it was concluded that: “native Coca leaves contain a body intimately associated with the cocaine and reacting to the same test, which almost wholly disappears from them in transit.”

This result indicates the presence in Coca leaves of some extremely volatile principle to which decided physiological properties are attached, which may also be obtained from suitably preserved leaves. When a preparation made from recent leaves in Bolivia was submitted to Professor Remsen, of Johns Hopkins University, his assistant reported that he found a bitter principle, and an oil, which presumably differed in no way from that found at the time of the examinations made in Bolivia. This is comparable with similar findings of those who have experimented with Coca, whether the leaves were recent and examined on the spot, or the examination had been made thousands of miles distant upon well preserved leaves. In each instance similar volatile alkaloids have been obtained, which have commonly been pronounced “decomposition products,” yet, as these are always found by careful observers, it indicates they are the natural associate bases of Coca.

The conclusions are that crude cocaine is not merely a single alkaloid. As the yield of crystallizable cocaine from the crude alkaloid varies from fifty to seventy-five percent, the associate alkaloids, together with the impurities and contaminations of manufacture, must constitute the remaining twenty-five or fifty percent, of the substance. Though our knowledge of these alkaloids is not yet exact, each of them has been found to possess certain chemical characteristics and sufficient physiological influence to prove a factor in the action of Coca. While these several Coca bases have been experimented with physiologically to a limited extent, they have never been individually applied to therapeutic uses. They have been regarded by the manufacturers of cocaine as simply so much waste from their yield of cocaine, and the attention of chemists has been directed to converting them by some synthetic process to what has been regarded as the pure alkaloid.

In the chemical constitution of cocaine there is a methyl, CH3, and a benzoyl, C6H5CO2, radical, either of which can be replaced by other acid radicals and so give rise to various homologues – or compounds of similar proportions. The methyl radical has been shown to be essential to the anӕsthetic action, and its presence or absence in the chemical group constitutes a poisonous or non-poisonous Coca product. By heating the Coca bases with alkyl iodides the corresponding esters are obtained. Thus methyl-benzoyl-ecgonine (cocaine); ethyl-benzoyl-ecgonine (homococaine); methyl-cinnamyl-ecgonine (cinnamyl-cocaine), etc., are formed. Acting upon this data, Merck, by heating benzoyl-ecgonine with a slight excess of methyl-iodide and a small quantity of methylic alcohol to 100° C, evaporating the excess of methyl-iodide and methylic alcohol, obtained a syrupy liquid containing cocaine hydriodate, from which an artificial cocaine was produced. In a similar way Skraup, by heating benzoyl-ecgonine, sodium-methylate and methyl-iodide in a sealed tube, made a synthetic cocaine, although the yield was only about four percent, while that of Merck was nearly eighty percent of the theoretical quantity.

In following this process, but using ethyl iodide, Merck obtained a new base, or homologue, cocethyline, or homococaine, with the formula C18H23NO4, which crystallizes from ether in colorless, radiating prisms, and from alcohol in glossy prisms, which melt at 1080 – 1090 C. The alkaloid is sparingly soluble in alkalies; chloride of gold gives a voluminous yellow precipitate, and chloride of mercury a white, pulverulent one, soluble in hot water. Falck has ascertained that cocethyline has an anӕsthetic action similar to cocaine, though weaker.

In following a similar method, but employing propyl iodide and propyl alcohol, and again by the use of iso-butyl-iodide with its corresponding alcohol, coc-propyline and coc-iso-butyline have been respectively formed, both of which have a strong anaesthetic action, and, though chemically different, exhibit the same reactions as cocaine.

Ecgonine has been converted into a new base by heating it for twenty-four hours with aqueous potash. This differs from ecgonine by being less soluble in absolute alcohol, in having a higher melting point, and in being dextro-rotary, and hence termed dextro-ecgonine. From this there has been prepared synthetically a dextro-cocaine, a colorless oil which solidifies and forms crystals on standing which are readily soluble in ether, alcohol, benzine and petroleum spirit. This body resembles cocaine, but its action is more fugitive.

Patenting The Magic Bullet – And Ignoring The Divine Leaf

From the ready conversion of the various Coca bases experimentally it was but a step to the building up of the associate bases into a synthetic salt of cocaine. This has given rise to a profitable industry, the process for which has been patented in Germany. In this process the mixed bases are converted by hydrolysis to ecgonine, then to a solution of hydrochloride of that salt in methyl alcohol. The hydrochloride of ecgonine methyl-ester is formed, and from this the salt is crystallized and heated over a water bath with benzoyl chloride, the homogenous mass being washed and separated from benzoic acid, and the cocaine precipitated with ammonia and crystallized from alcohol.

(From) American Druggist, January 1889

As is well-known, coca leaves, upon extraction, do not yield at once pure cocaine. The latter is always accompanied by a number of amorphous secondary alkaloids, which have to be separated before pure, crystallized cocaine can be obtained.

The nature of one of those secondary alkaloids has recently been cleared up by one of the authors of the present paper. As a general result of the preliminary studies, it was found that all the amorphous alkaloids, upon being boiled with acid, yield the base ecognine. The latter is very easily obtained by boiling the alkaloids for about one hour with hydrochloric acid, filtering off the separated acids (benzoic, etc) evaporating the acid filtrate to dryness, and boiling the dry residue with alcohol to remove further portions of benzoic or other acids. Pure hydrochlorate of ecognine is left behind.

The base is set free with soda, and purified by recrystallization from alcohol. Ecognine thus obtained was found to be absolutely identical with ecognine derived from crystallized cocaine.

It now became a question whether ecognine could not be converted back into cocaine by some simple, practical process. Between ecognine and cocaine there is an intermediate base, benzoyl-ecognine, which consists of ecognine in combination with the benzoyl nucleus. Heretofore benzoyl-ecognine had only been obtained either as a companion of cocaine or as a [product of the decomposition of the latter, but never as a synthetic product. This synthesis has now been accomplished by the authors and the gap between ecognine and cocaine thereby bridged over.

The problem was how to cause the benzoyl nucleus to combine with the ecognine. This was easily accomplished by means of anhydrous benzoic acid (benzoic anhydride) as well as by benzoyl chloride. The following method is given by the authors from their patent dated August 17th, 1888.

Make a hot saturated solution of ecognine ( one molecule) in about half its weight of water, and digest it at the temperature of the water bath for about one hour with somewhat more than one mol. Of benzoic anhydride added gradually. The n set it aside. It will solidify on cooling or standing, or while being agitated with ether, which is required to remove the excess of the benzoic anhydride added and the benzoic acid formed. The benzoyl-ecognine which has been formed, as well as any unaltered ecognine, are almost insoluble in ether and remain behind. The ethereal solution, upon evaporation, leaves behind all the benzoic acid used in excess. In order to obtain the synthetic benzoyl-ecognine pure, the residue, after treatment with ether is titrated with a very small quantity of water, and the liquid portion separated with a filter pump. Benzoyl-ecognine remains behind, while the much more soluble ecognine is dissolved out. If care is taken, the yield of benzoyl-ecognine amounts to eighty percent of the weight of the original ecognine. From the mother liquids some more benzoyl-ecognine may be obtained by evaporation. And all the unconverted ecognine is recovered and added to the next operation.

Benzoyl-ecognine thus obtained was found to absolutely identical with that previously known as a decomposition product.

The conversion of benzoyl-ecognine into cocaine had already been accomplished or at least pointed out some time ago by Einhorn. In 1885 W. Merck found that by heating benzoyl-ecognine with iodide of methyl and methylic alcohol in sealed tubes the former was partly converted into cocaine. But the yield was only about 4% of the amount of benzoyl-ecognine employed. Einhorn subsequently discovered a much more simple and efficient method for converting benzoyl-ecognine into ethylic or other compound ethers.

Cocaine is chemically benzoyl-ecognine-methylic ester. The method which Einhorn used to produce the ethylic ester was as follows:

Make a solution of benzoyl-ecognine in ethylic alcohol and pass dry hydrochloric acid gas into it, which will cause a considerable rise in temperature for some time. Keep on passing the gas until the liquid has become cold. Then boil it for one hour under an upright condenser and afterwards evaporate it on a water bath. Dissolve the residue in water and precipitate the filtered solution with soda. The precipitate in this case was a base which differed from natural cocaine by containing the ethyl nucleus C2H3 instead of that of Methyl CH3 which exists in true cocaine. In order to obtain the latter it is only necessary ( at least this is implied by the statements of Lieberman an d Giesel) to substitute pure methylic alcohol for the ethylic, to pass dry hydrochloric gas through the solution, and to proceed further as described. By this method an extremely pure cocaine is obtained which forms magnificent crystals. This synthetic cocaine has been tested for its physiological effects by Prof. O. Liebreich and ascertained by him to be identical with that directly obtained from coca.”

The proportion of alkaloids contained in Coca leaves is influenced by the method of the growth of the plant, and the yield is dependent upon the manner of curing the leaves and their preservation. The percentage ranges from a mere trace to about one per cent. Bignon considers that well preserved leaves will yield fully as much as recent leaves, varying from nine to eleven grammes of the mixed alkaloids per kilogram, the latter being more than one per cent. Niemann obtained from his original process 0.25 per cent, of cocaine, while the present yield is more than double that. From a number of assays made during the last few years in the laboratory of an American manufacturer the following percentages of alkaloid were obtained: 0.53, 0.51, 0.63, 0.63, 0.57, 0.60, 0.66, 0.55, 0.70, 0.70, 0.65, 0.67, 0.54, 0.70, 0.32, 0.42, 0.52, 0.85, 0.48, 1.3, 0.78, 0.70, 0.40, 0.63. This will serve as an index of the quantity of total alkaloid commonly found in the average leaf of good quality as it reaches North America.

In determining the amount of alkaloids present in a given specimen of Coca, it is essential that the selected leaves be finely powdered, and mixed with a suitable menstruum that will not cause undue annoyance from gummy and resinous matters while setting free the essential constituents. These are washed out of the solution by an appropriate solvent, dried and weighed, or estimated by using some reagent the equivalent values of which have been determined by experiment. Various alkalies, as lime, soda or magnesia, have been suggested for admixture with the leaves for the purpose of liberating the alkaloids, which are transformed to soluble salts by acidulated water and washed out with strong alcohol. The details of the production of the Coca alkaloids commercially are kept as a trade secret, but the broad methods of manufacture are all similar, as several will illustrate.

Dr. Squibb has suggested the following process for the preparation of cocaine on a small scale: One hundred grammes of finely ground leaves are moistened with 100 c.c. of 7 percent solution of sodium carbonate, packed in a percolator, and sufficient kerosene added to make 700 c.c. of percolate. This is transferred to a separator, and 30 c.c. of 2 percent solution of hydrochloric acid added and shaken. After separation the watery solution is drawn off from below into a smaller separator, and this process is repeated three times, the alkaloid being in the smaller separator as an acid hydrochlorate. This is precipitated in ether with sodium carbonate, and evaporated at low heat with constant stirring and the product weighed.

Another process is to digest Coca leaves in a closed vessel at 700 C. for two hours with a very weak solution of caustic soda, and petroleum boiling between 2000 to 250°. The mass is filtered, pressed while tepid, and the filtrate allowed to stand until the petroleum separates from the aqueous liquid. The former is then drawn off and neutralized with weak hydrochloric acid. The bulky precipitate of cocaine hydrochloride being recovered from the aqueous liquid by evaporation.

Gunn made a series of tests to determine what relation the methods of extraction had to the alkaloidal yield, and concluded that the modified method of Lyons obtained the most alkaloids. This is substantially as follows: Shake 10 grammes of finely powdered leaves with 95 c.c. of petroleum benzin and add 5 c.c. of the following mixture: Absolute alcohol, 19 volumes; concentrated solution ammonia, 1 volume. Again shake for a few minutes, and set aside for twenty-four hours with occasional shaking. Decant rapidly 50 C.C. of the clear fluid, or, if it is not clear, filter it, washing the filter with benzin. Transfer to a separator containing 5 C.C. of water, to which has been added 6 to 8 drops of dilute sulphuric acid (1 to 5 by weight). Shake vigorously; when the fluids have separated draw the aqueous portion into a one ounce vial. Wash the contents of the separator with 2 c.c. of acidulated water (1 drop of the dilute acid). Shake, draw off into the vial, and continue this two or three times, until a drop tested on a mirror with Mayer’s reagent shows only faint turbidity. Add to the aqueous fluid 15 c.c. of benzin, shake, and when separation is complete, pour off the benzin. Add to the vial 15 c.c. of stronger ether, U. S. P., with sufficient ammonia to render the mixture decidedly alkaline. Shake, and when separation is complete, decant the ether carefully into a capsule. Wash the residue in the vial with two or three successive portions of fresh ether until the aqueous fluid is free from alkaloid, as shown by the test. Evaporate the ether over a water bath. Dry the alkaloid to constant weight, weigh, multiply the result expressed in decigrammes by two, which will present the percentage of crude cocaine.

Instead of extracting the alkaloid from the acid aqueous solution a simple method adapted to use in the field may be followed, in which the alkaloid is estimated by titration with Mayer’s reagent. An acid solution representing 5 grammes of the leaves should be made up to a volume of 15 c.c, and the reagent added as long as it continues to precipitate in the clear filtrate. In this way, with half strength solution, 3.5 c.c reagent represents 0.2 per cent, of alkaloid.

Mayer’s reagent, or the decinormal mercuric potassium iodide of the U. S. P., is prepared as follows: Mercuric chloride, 13.546 grammes, dissolved in 600 c.c. of water; potassium iodide, 49.8 grammes, dissolved in 190 c.c. of water; mix the two solutions and add sufficient water to make the whole measure, at 590 F., exactly 1000 c.c.

When Mayer’s reagent is added drop by drop to an acid solution containing cocaine (1:200 to 1:600) there is at first produced a heavy white precipitate, which collects at once into curdy masses; a drop of solution should be examined on a mirror, and should not show more than slight turbidity when determining the final traces. Dr. Lyons suggests that after adding a certain quantity of the reagent it will be found that the filtered fluid which still gives a heavy precipitate with Mayer’s reagent produces a precipitate also in a fresh solution of cocaine. It is thus evident that the precipitation is complete only when an excess of reagent is present in the fluid; and it is found advisable to correct the reading from the burette by subtracting for each c.c. of fluid present at the end of the titration 0.085 c.c. (if the half strength reagent is used); the remainder multiplied by ten will give the quantity of alkaloid indicated in milligrammes. The best method of following the process is to throw the fluid on a filter after each addition of reagent. Solutions of the alkaloid 1 :400 appear to yield better results than solutions stronger or weaker than this.

One c.c. of Mayer’s reagent will precipitate about 7.5 milligrammes of the mixed alkaloids from solutions in which alcohol is not present. As a rule the quantity of alkaloidal precipitate by this reagent is greater than the quantity of cocaine that can be extracted by washing out the alkaline solution with ether, so that in exact examinations a recourse to weighing is considered advisable. The dried precipitate weighed and multiplied by 0.406 will give about the amount of alkaloid present. With Mayer’s reagent used in half strength the following values for the equivalent of the reagent are given:

ChX_Table1

The following table may also be of service:

ChX_Table2
Results higher or lower than those indicated are beyond the limits of the experiment and would call for repetition.

The principal tests employed to determine the purity of cocaine hydrochloride are the permanganate of potash and Maclagan’s ammonia test. When one drop of a one percent solution of permanganate of potash is added to 5 c.c. of a two percent solution of hydrochloride of cocaine mixed with three drops of dilute sulphuric acid, it occasions a pink tint which should not entirely disappear within half an hour. When added to a stronger solution it occasions a precipitate of rhombic plates, which decompose on heating. If cinnamyl-cocaine be present the odor of bitter almonds is given off with the decomposition.

The Maclagan test is based upon the supposition that the amorphous alkaloids of Coca when set free by ammonia are separated as oily drops and so form a milky solution. It is employed by adding one or two drops of ammonia to a solution of cocaine, which is then vigorously stirred with a glass rod. If the salt is pure a formation of crystals will be deposited upon the rod and upon the side of the vessel within five minutes, while the solution will remain clear. If isatropyl-cocaine be present crystallization will not take place and the solution will become milky.

Considerable stress has been laid upon the value of this test for determining the purity of cocaine salts. Dr. Guenther asserts that a perfectly pure cocaine will not show the Maclagan reaction, while if a small quantity of a new base which he described as cocathylin, with a melting point of 1100 C, be present, the test will be pronounced. In endeavoring to show that this was an error, one of the largest manufacturers of cocaine in Germany worked up four thousand kilos of Coca leaves, and though they failed to find the new base which had been mentioned, they also proved that a pure cocaine will respond positively to the Maclagan test. In support of this Paul and Cowley have expressed the opinion that any cocaine which does not satisfy this test should not be regarded as sufficiently pure for pharmaceutical purposes, views which are also maintained by E. Merck.

Of the various reagents that have been found delicate in testing for cocaine Mayer’s reagent will detect one part in one hundred thousand, while a solution of iodine in iodide of potash will determine one part in four hundred thousand, with a very faint yellow precipitate.

It has been shown by Gerrard that mydriatic alkaloids have a peculiar action with mercuric chloride, from the aqueous solution of which they precipitate mercuric oxide, the other natural alkaloids giving no precipitate at all, or at least not separating mercuric oxide. The late Professor Flückiger, verifying this action on cocaine, found the test recorded a very abundant purely white precipitate, which very speedily turned red, as in the case of the other mydriatic alkaloids.

It has been found, on treating cocaine or one of its salts in the solid state with fuming nitric acid, sp. gr. 1.4, evaporating to dryness and treating with one or two drops of strong alcoholic solution of potash, there is given off on stirring this with a glass rod a distinct odor suggestive of peppermint. This odor test has been pronounced very delicate and is distinctive for cocaine, no other alkaloid having been found to yield a similar reaction.

There are several cocaine manufacturers in Peru. A few years ago there were five in Huanuco, one in the District of Mozon, one in Pozuso, two at Lima, one at Callao, at least two of which are run on an extensive scale. In 1894 the amount of the crude product manufactured in Peru and sent abroad for purification was four thousand seven hundred and sixteen kilos. A personal communication from Peru, dated January 15, 1900, states that the local manufacturers of cocaine are increasing their facilities and claim that they work with a better method than is followed elsewhere.

In 1890 Dr. Squibb called attention to the fact that crude cocaine was made so efficiently in Peru that it seemed highly probable that the importation of Coca leaves to this market was nearly at an end. This crude cocaine has a characteristic nicotine odor; it comes in a granular powder or in fragments of press cake, generally of a dull creamy white color, but rarely quite uniform throughout, the color ranging from dirty brownish white to very nearly white. Some of the fragments are horny, compact and hard, while others are softer and more porous. The following process has been given for determining the amount of cocaine present in the crude product:

A small quantity being taken from a large number of lumps in the parcels, selected on account of their difference in appearance, the determination of moisture in the samples so selected is found by fusion at 910 C. The solubility of the samples in ether at a specific gravity .725 at 15.60 C, is then tested. The insoluble residue is thoroughly washed with ether, dried and weighed. The alkaloid dissolved by the ether is converted into oxalate, and the oxalate shaken out by water. The residue which is soluble in ether is then determined by evaporation of the ethereal solution. The aqueous solution of cocaine oxalate is rendered faintly alkaline by soda; the freed alkaloid shaken out with ether, and after spontaneous evaporation of the ether and complete drying of the crystals produced, the pure alkaloid is estimated. The usual yield of pure crystallizable alkaloid from this crude product varies from fifty to seventy-five percent.

Crude cocaine when united with acids assumes an intense green color, due to the presence of benzoyl-ecgonine, while its characteristic chemical reaction is its property of splitting into benzoic acid and methyl alcohol. Cocaine combines readily with acids to form salts, which are readily soluble in water and alcohol, though insoluble in ether. These salts, owing to their more ready solubility, have a more marked anӕsthetic action on mucous surfaces than the pure alkaloid. There has been prepared benzoate, borate, citrate, hydrobromate, hydrochlorate, nitrate, oleate, oxalate, salicylate, sulphate, tartrate, etc.

According to the U. S. Pharmacopaia the following are the characteristics of cocaine hydrochlorate, the salt commonly employed: “Colorless, transparent crystals, or a white crystalline powder, without odor, of a saline, slightly bitter taste, and producing upon the tongue a tingling sensation, followed by numbness of some minutes’ duration. Permanent in the air. Soluble at W C. (59o F.) in 0.48 part of water and in 3.5 parts of alcohol; very soluble in boiling water and in boiling alcohol; also soluble in 2,800 parts of ether or in 17 parts of chloroform. On heating a small quantity of the powdered salt for twenty minutes at a temperature of 100° C. (212° F.), it should not suffer any material loss (absence of water of crystallization). The prolonged application of heat to the salt or to its solution induces decomposition. At 193° C. (379.4° F.) the salt melts with partial sublimation, forming a light brownish yellow liquid. When ignited it is consumed without leaving a residue. The salt is neutral to litmus paper.

In reviewing the research of many workers it may be seen how each has closely approached, often with a mere hint or suggestion, results which later have been verified and described more in detail. Through this repetition many new facts have been made positive to us. Assertions have been strengthened or have been cast aside, and while the result has been to render a cocaine of purer quality, it has at the same time emphasized the immensity of our ignorance concerning the subtleties of alkaloidal formation. More than all, these researches must impress the fact that similar changes to those which are possible in the laboratory of the chemist are also at work in Nature’s laboratory, and that the therapeutic influence and efficiency of Coca, as of any remedy taken into the body, must be markedly affected by the transmutations of the organism.” (End of Chapter)

A Respectful Suggestion For President Evo Morales

Dear Mr. President:

Your strong support for the indigenous people of Bolivia is well-known, as is your courageous stand against antagonistic outside political forces. You are also respected by millions worldwide for your practical and honest approach to the so-called “drug problem”, and your dedication to economic development and broad economic prosperity. Further, it is well-known that you are working hard to improve the health and quality of life of the Bolivian people.

May I suggest that all of these strengths that you bring to the service of your country can be combined in a way that is uniquely Bolivian and that will bring substantial new economic benefits to your country? I am speaking of the worldwide phenomenon of “Medical Tourism” and a plan for Bolivia to benefit greatly from the willingness of people to travel to wherever they can get the best and least expensive medical treatment for a wide range of diseases and conditions.

The global Medical Tourism market is estimated at $30 Billion as of 2013 and is growing at approximately 17% a year. By far the greatest concentration of Medical Tourism is in Asia, and most Medical Tourists are seeking high-tech medical treatments at low cost in hospital settings.

However, I believe that Bolivia is in a position to develop and capture a new area of Medical Tourism that will be worth many times more to Bolivia than the entire current Medical Tourism market of $30 Billion worldwide. I am speaking of the remarkable healing power of pure, natural Coca Leaf – not Cocaine – and the fact that this healing power is fully documented and validated by hundreds of years of medical and scientific research.

I propose that Bolivia is in a unique position to provide Medical Tourists not with hospital-based services that require expensive medical technology infrastructure but with a network of simple, comfortable, pleasant Spas where people can come from around the world to be given Coca Leaf teas and tonics under medical supervision for conditions that cannot be effectively treated by any other kind of therapy.

Let me offer just one example. In the US alone, approximately $270 Billion is spent annually on Obesity treatments, medications, surgeries, and diets. This $270 Billion is only what is spent on medically-defined obesity. When you take into account the wealth that is spent on simple cosmetic & vanity weight loss, the total is staggering. And this in only what is being spent annually in the US. When you consider that overweight conditions up to and including obesity are a worldwide problem, it is easy to see that expenditures on this one issue alone probably exceed $500 Billion. A large proportion of this spending could be attracted to the network of Bolivian Coca Leaf Spas that I am proposing.

As you know, Coca Leaf has been illegal in most countries for many generations, and there is no need to go into the reasons why this is so. However, as I am sure you also know prior to becoming a banned substance Coca Leaf teas and tonics were in use with great success worldwide as a completely safe, non-addictive, and very effective weight loss treatment.

There is no reason at all why Bolivia, as one of the few countries in the world where Coca Leaf is understood as a great gift of nature and not as an evil drug, could not initiate a nationwide network of Spas for weight loss treatments based on this simple principle. When you consider that people who need to lose 50-100 Kilograms of body weight could do so at such Spas without any risk, and without the unpleasantness of restricted diets and dangerous surgeries, perhaps you will agree that this represents great economic potential for Bolivia.

When you further consider that these Spas would, in many cases, be located at traditional hot springs that are located on land owned by the indigenous people, and that for the most part it is Bolivia’s indigenous people who have the traditions and skills to produce high quality Coca Leaf, it is clear that Bolivia’s indigenous people would be among the greatest beneficiaries of such a program.

And please, Mr. President, note that so far I have only been discussing Coca Leaf Spas as centers for the treatment of body weight problems. As I am sure you and your medical advisors know, Coca Leaf teas and tonics have been proven to effectively and safely treat and cure a wide range of conditions and diseases on which hundreds of billions of dollars are spent annually without results and, in many cases, with dangerous side-effects. The same Coca Leaf Spa network that would treat obesity and simple cosmetic weight loss could also treat this extensive range of diseases and conditions.

The potential Medical Tourism market for services that could be offered by a Bolivian network of Coca Leaf Spas includes:
Bolivia_$
Finally Mr. President, may I suggest that a Coca Leaf Spa/Medical Tourism program would offer Bolivia an opportunity to end or at least greatly diminish Bolivian involvement in the international drug trade? Under your leadership the criminal cartels that dominate the illegal drug trade could be offered the opportunity to become minority shareholder/investors in the network of Coca leaf Spas, which I suggest could be majority owned by cooperatives controlled by indigenous peoples. The condition for allowing this investment would be that these cartels turn away from the international drug trade, which brings AT MOST $20-30 Billion a year, and turn their considerable business know-how and innovative energies to assisting indigenous people in operating the Coca leaf Spa network – under close supervision to prevent any abuses on the part of these Cartel members who are accustomed to getting their own way – then they would have an opportunity to make more money than they are currently making risking their lives in armed combat against the forces of the governments of North America and Europe, and they would be able to do so in a safe and entrepreneurial environment.

Is this proposal naïve? Am I deluded about the possibility that the operators of the Cocaine trade could “come in from the cold”? Could I be mistaken to think that Medical Tourists would choose Bolivian Coca Leaf spas over high-tech hospitals in Asia? Perhaps. But then again, perhaps not.

Mr. President, you are a man of vision – that is clear. I urge you to look carefully at this proposal and to consider what could happen if it were not a naïve delusion but instead a practical plan for Bolivia to take advantage of a unique resource for the benefit of both the Bolivian people and of people worldwide who presently are at the mercy of the industrial medical/pharmaceutical complex, with its limited success and unlimited greed.
