Ayahuasca

Ayahuasca (ayawaska pronounced in the Quechua language) is a brew of various psychoactive infusions or decoctions prepared with the Banisteriopsis caapi vine. It is usually mixed with the leaves of dimethyltryptamine (DMT)-containing species of shrubs from the genus Psychotria. The brew, first described academically in the early 1950s by Harvard ethnobotanist Richard Evans Schultes, who found it employed for divinatory and healing purposes by the native peoples of Amazonian Colombia, is known by a number of different names (see below). It has been reported that some effects can be had from consuming the caapi vine alone, but that DMT-containing plants (such as Psychotria) remain inactive when drunk as a brew without a source of monoamine oxidase inhibitor (MAOI) such as B. caapi. How indigenous peoples discovered the synergistic properties of the plants used in the ayahuasca brew remains unclear. While many indigenous Amazonian people say they received the instructions directly from plants and plant spirits, researchers have devised a number of alternative theories to explain its discovery.
