RESUMO

The contribution of non-European cultures to science and technology, primarily to chemistry, has gained very little attentions until now. Especially the high technological intelligence and inventiveness of South American native populations shall be put into a different light by our contribution. The purpose of this essay is to show that mainly in the area of chemical practices the indigenous competence was considerable and has led to inventions profitable nowadays to millions of people in the western world and especially to the pharmacy corporations. We would like to illustrate this assumption by giving some examples of chemical practices of transformation of substances, mainly those unknown in the Old World. The indigenous capacity to gain and to transform substances shall be shown here by the manufacture of poisons, such as curare or the extraction of toxic substances of plants, like during the fabrication of manioc flower. We shall mention as well other processes of multi-stage transformations and the discovery and the use of highly effective natural substances by Amazonian native populations, such as, for example, rubber, ichthyotoxic substances or psychoactive drugs.
