Ayahuasca is a psychedelic (define psychedelic?) plant beverage or tea obtained from Banisteriopsis caapi together with the leaves of Psychotria viridis or Diplopterys cabrerana. It is used by healers and shamans in the Amazon Basin for curing diseases (folk medicine) and for magico-religious practices (contacting spirits or the dead ones). The ritual use of Ayahuasca is considered sacred and important in the religions indigenous to South America. The woody vine (Banisteriopsis caapi) is the basic ingredient of the Ayahuasca beverage, and is seldom used alone to make the Ayahuasca beverage or tea. It usually contains other plants as mentioned above along with the woody vine. For more information on Ayahuasca, refer to this research article: Ayahuasca – The Sacred Psychedelic!! | adidarwinian.
