The brew, first described academically in the early 1950s by Harvard ethnobotanist Richard Evans Schultes, who found it employed for divinatory and healing purposes by the native peoples of Amazonian Peru.

People who have consumed ayahuasca report having massive spiritual revelations regarding their purpose on earth, the true nature of the universe as well as deep insight into how to be the best person they possibly can. This is viewed by many as a spiritual awakening and what's often described as a rebirth. In addition it is often reported that individuals can gain access to higher spiritual dimensions and make contact with various spiritual or extra dimensional beings who can act as guides or healers.It's nearly always said that people experience profound positive changes in their life subsequent to consuming ayahuasca and it is often viewed as one of the most effective tools of enlightenment.

However, during an ayahuasca experience, people sometimes report nausea, diarrhea, and cold flashes. Significant but temporary emotional and psychological distress can also occur.
