Teacher plants - Indigenous Peruvian-Amazonian dietary practices as a method for using psychoactives.

Journal of ethnopharmacology March 25, 2022 Ilana Berlowitz, David M O'Shaughnessy, Michael Heinrich et al. 26 citations

The Peruvian-Amazonian dieta is a retreat-like intervention involving lengthy social, behavioral, and alimentary restrictions while ingesting specially prepared plant substances, many of which are psychoactive. Based on interviews with 16 healers from Ucayali, San Martín, and Loreto provinces, the method is described as transformative, with multifaceted applications for treatment, prevention, and training. Benefits are attributed to teacher plants, dietary conditions, and the healer's skill. A detailed risk assessment revealed sophisticated safety measures. The dieta is a central therapeutic concept and a unique method for using psychoactive plants, warranting inclusion in current psychedelic research.
