Sacred Mushroom of Visions: Teonanácatl: A Sourcebook on the Psilocybin Mushroom

Psilocybin mushrooms known as Teonanácatl are presented as a sourcebook for understanding visionary mushroom experiences and how psilocybin mushroom use spread from Mexico into other regions. The book compiles perspectives from many contributors covering chemical and biological dimensions, cultural context, psychological impacts, and experiential reports from users, including artists and psychologists. It includes firsthand accounts tied to the controversial Harvard Psilocybin Project, such as the Concord Prison and Good Friday studies, and discusses how psilocybin has been used since the 1960s in psychotherapy and prisoner rehabilitation. It also highlights research directions including studies related to obsessive compulsive disorder (OCD), while connecting modern interest to the Mazatec healer Maria Sabina and mycologist R. Gordon Wasson and their role in the mushrooms rediscovery.
