The authors summarize its history, how it acts in the body and brain, what people report feeling during the experience, and the early research on possible medical use. Interest in ayahuasca has grown a lot since about 2000. Reports range from strong healing stories to accounts of physical or psychological harm. The reviewers conclude ayahuasca looks promising but needs much more careful research on how it works and whether it can help treat mental health problems safely.

Abstract
Ayahuasca is a psychedelic plant brew originating from the Amazon rainforest. It is formed from two basic components, the Banisteriopsis caapi vine and a plant containing the potent psychedelic dimethyltryptamine (DMT), usually Psychotria viridis. Here we review the history of ayahuasca and describe recent work on its pharmacology, phenomenological responses, and clinical applications. There has been a significant increase in interest in ayahuasca since the turn of the millennium. Anecdotal evidence varies significantly, ranging from evangelical accounts to horror stories involving physical and psychological harm. The effects of the brew on personality and mental health outcomes are discussed in this review. Furthermore, phenomenological analyses of the ayahuasca experience are explored. Ayahuasca is a promising psychedelic agent that warrants greater empirical attention regarding its basic neurochemical mechanisms of action and potential therapeutic application.
