Abstract

Reports on the inebriating properties of plants—some employed in magico-religious ceremonies of primitive societies in various parts of the world—continue to appear. Their sources are many: reports of travellers, anthropological writings, historical documents, herbarium specimens and others. The diversity and wide occurrence of the reports have tended to keep them from the scrutiny of investigators who might have studied the plants for the ascertainment of their active principles. In an effort to focus attention on some of these presumably psychoactive plants, the following notes are offered. Only those species which seem most urgently in need of attention are listed. There are others which appear to be promising albeit not of such immediate interest because of the vagueness of the ethnobotanical reports of their use or because of extreme difficulty in procuring sufficient supplies of the plant for phytochemical study. Even though the number of species listed below is limited, it is obvious how much remains to be done in the interdisciplinary study of biodynamic plants. A very recent survey of natural hallucinogens has pointed out that more than 200 species of higher plants comprise the study, that they are widely distributed in the plant kingdom (146 genera in more than 50 families) and that the active principles are known for only about 45 species (Schultes and Farnsworth 1980)Bot. Mus. Leaft., Harvard Univ. 28 (186–190). This survey attributes the lack of chemical knowledge of these plants to two causes: (i) the lack of good animal models which the chemist can utilize in monitoring his isolation work; and (ii) the paucity of field work of scientific trustworthiness in fast disappearing aboriginal societies. The survey ends with the statement that the “… Plant kingdom remains a fertile and almost virgin territory for those interested in the discovery of new psychoactive drugs, not to mention other types of biologically active compounds waiting in silent hiding.” The extreme paucity of phytochemical studies on these plants of very significant use in primitive societies emphasizes one of the most important results from ethnobotanical investigations: the ability to orient chemical analyses along lines of biodynamically useful species.

16. The Amazonia as a source of new economic plants

Abstract

Those who understand and love the Amazon forest call it the Green Heaven. Those who misunderstand and despise it know it by the name of the Green Hell. A recent political figure has termed the Amazon a desert of trees which must be destroyed. Unfortunately this latter point of view seems now to be in the ascendency. Why should this vast area of 2,700,000 square miles be protected? There are many reasons for the preservation of this last great wet tropical forest which may comprise as many as 100,000 species of plants. Today I want to discuss with you only one of these reasons-but one which, for the future of mankind, appears to me to be one of the most compelling: its incalculable value as an untapped emporium of germ plasm for new economic plants. The great Russian botanist Vavilov postulated that there were eight major centres of the origin of cultivated plants. Some botanists have pointed out that these centres nearly cover the world's surface. This is not, however, a valid criticism. Most of Africa, with the exception of Abyssinia, has given little to the store of man's economic plants. Australia has yielded no major species. All of North America north of Mexico has been singularly parsimonious. What about the tropical Amazon forests? The tapioca plant, Manihot esculenta, appears to have originated in the Amazon. In pre-Columbian times, it had spread throughout tropical America. It now has taken its place as one of the dozen or thirteen major food plants of the world, having been accepted as the prime source of carbohydrate in many tropical parts of Africa and Asia. The cultivated pineapple, Ananas comosus, is thought to have originated in the western part of the Amazon Valley from wild types such as A. microstachys. Specialists now believe that the cultivated cacao tree, source of chocolate, arose through hybridization of wild species in the westernmost Amazon of Colombia and Ecuador. It is probable that the narcotic coca plant, Erythroxylon Coca, originated in the eastern or Amazonian slopes of the Ecuadorian Andes. The southwestern part of the Brazilian Amazon appears to be the home of achiote, Bixa Orellana, now widely cultivated throughout the tropics; it arose possibly from the wild B. excelsa of the Acre area. Another recently domesticated plant of the Amazon is timb6 or barbasco, various species of Lonchocarpus, especially L. utilis, a main source of the insecticide rotenone. For many years now, the guarana plant, Paullinia cupana, has been cultivated in the central part of the Amazon for the preparation of various caffeine-rich beverages. But undoubtedly no native of Amazonia has so altered human life around the globe as the Para rubber tree, Hevea brasiliensis, one of the most recently domesticated of our major crops. Were it only for the impact of three of these cultigens on modern living

Abstract

The Space Age is upon mankind. It beckons to incredibly strange and promising areas of new discovery. It is wonderful to be alive at such a time and to dream about what may be ahead in learning. Some of us hope, however, that space study will not lessen the attention given to the many fields anchored on this small globe. One of the many fields of this kind is investigation of the Plant Kingdom as it relates to the liberation of man from pain and sickness. How are we to proceed in furthering our understanding of this phase of the plant sciences? There are three main methods -which may be followed: one is basically bibliographic; two are concerned primarily with field work. Both the bibliographic and the field methods may sometimes of necessity or advantageously be interwoven. These three paths of research are: 1) a survey of the literature for reports of therapeutic uses of or beliefs about plants; 2) the chemical investi gation of definite floras or of chosen families or genera of plants in the search for new active principles; 3) the field study of ethnobotany amongst primitive peoples. Primitive man everywhere lived close to nature. An important-yes, an essential -part of his equipment was a deep and discerning acquaintance with the flora around him. This acquaintance led inevitably to experimentation. From the experimentation there gradually accrued a knowledge of properties, useful and harmful, of many plants. And this knowledge
