Ayahuasca

South American psychoactive decoction

Ayahuasca is a South American psychoactive decoction prepared from Banisteriopsis caapi vine and a dimethyltryptamine (DMT)-containing plant, used by Indigenous cultures in the Amazon and Orinoco basins as part of traditional medicine and shamanism. The word ayahuasca, originating from Quechuan languages spoken in the Andes, refers both to the B. caapi vine and the psychoactive brew made from it, with its name meaning 'spirit rope' or 'liana of the soul'. Although often portrayed as ancient, ayahuasca likely spread across the western Amazon only within the past few centuries; the first clear written accounts appear in the 17th century.
