Ayahuasca (Quechua, pronounced [ajaˈwaska]) is any of various psychoactive infusions or decoctions prepared from the Banisteriopsis spp. vine, native to the Amazon Rainforest (which is also called ayahuasca). The resulting drinks are pharmacologically complex and used for shamanic, folk-medicinal, and religious purposes. To occidental ethno-biologists it is noted a variety of 200-300 plants are used in the different brews made by the Ayahuasceras. It is an open question whether Ayahuasca should be noted as one particular shamanic medicinal brew, or that it should be noted as an entire medicinal tradition specific to the Amazonas.
