What Is Ayahuasca?

Ayahuasca is test a psychoactive brew traditionally prepared by indigenous peoples of the Amazon basin. The name comes from the Quechua language, meaning "vine of the soul" or "vine of the dead." It has been used for centuries in spiritual and healing ceremonies across South America.

Ayahuasca is typically made from two plants: the Banisteriopsis caapi vine, which contains MAO-inhibiting harmala alkaloids, and the leaves of Psychotria viridis (chacruna), which contain the psychedelic compound DMT. The combination of these two plants is essential — the MAO inhibitors allow DMT to become orally active.

The effects of ayahuasca typically begin 30–60 minutes after ingestion and last 4–6 hours. Participants commonly report vivid visual and auditory experiences, deep emotional processing, feelings of connection with nature and the universe, and profound personal insights. Physical effects may include nausea and purging, which are considered part of the healing process in traditional contexts.

Archaeological evidence suggests ayahuasca use dates back at least 1,000 years. The brew has been central to the spiritual and medicinal practices of numerous Amazonian peoples, including the Shipibo, Asháninka, and Quechua. In the 20th century, syncretic religions such as Santo Daime and the União do Vegetal incorporated ayahuasca into Christian-influenced ceremonial practices.

In traditional settings, ayahuasca ceremonies are led by experienced curanderos or shamans who have undergone years of training and plant diets. The ceremonies typically take place at night in a ceremonial space called a maloca. The curandero guides the experience through sacred songs called icaros, which are believed to direct the healing energy of the medicine.

The legal status of ayahuasca varies significantly by country. In Peru, Brazil, and Ecuador, traditional use is legally protected. In the United States and most European countries, DMT is a controlled substance, though some religious organizations have obtained legal exemptions. International treaties do not specifically schedule the ayahuasca brew itself, creating a complex legal landscape.
