A general overview of various aspects of Amazonian coca (Erythroxylum coca var. ipadu) is presented. This plant is considered a distinct variety of coca which has been developed as a cultivated plant in the upper Amazon basin. It differs from typical Andean coca in morphological, physiological and chemical features as well as in the method of preparation and use by Amazonian tribes. The main topics here discussed are the history, distribution, botany, chemistry, origin, methods of preparation and use, and the effects of Amazonian coca.
