Ayahuasca Ceremony

The ayahuasca ceremony is a shamanic healing and divinatory ritual, indigenous to Indigenous peoples of the Amazon basin including groups in Peru, Ecuador, Colombia, and Brazil, centered on the communal drinking of ayahuasca, a psychoactive brew prepared by combining the Banisteriopsis caapi vine with a DMT-containing plant, most often Psychotria viridis, under the guidance of a trained shaman or curandero. Conducted at night and typically involving icaros, the shaman's sung or whistled healing melodies, the ceremony is understood within its originating traditions as a means of diagnosing and treating physical and spiritual illness, communicating with plant spirits and ancestors, and gaining knowledge or guidance through the intense visionary states the brew produces, with the shaman responsible for guiding participants through the experience and managing its physical and spiritual risks. Ayahuasca use has spread substantially beyond its Indigenous Amazonian origins over recent decades, incorporated into syncretic Brazilian religious movements such as Santo Daime and Uniao do Vegetal and drawing significant international ceremonial tourism and scientific research interest, developments that have generated ongoing anthropological and ethical debate over cultural appropriation, commercialization, and the preservation of Indigenous ceremonial authority over the practice.
