Ayahuasca’ is a plant mixture with a variety of recipes and localized names native to South America. Often, the woody ayahuasca vine (Banisteriopsis caapi) is combined with chacruna leaf (Psychotria viridis) in a tea, inducing psychedelic effects among its users. While social usage varies among Indigenous Peoples of South America, during the twentieth century new religious movements in Brazil began employing the mixture as religious sacrament. Additionally, various centers for ayahuasca “healing” have emerged both inside and outside of the Amazon Rainforest, frequently with the aim of helping people addicted to other substances. As interest grew, ayahuasca use in South America attracted large numbers of tourists. Use of it also began a worldwide diaspora.
