Dr. Osiris García Cerqueda is an Indigenous Mazatec historian and sociologist from Huautla de Jiménez, Oaxaca, Mexico. From a very young age, he has dedicated himself to the study of the history of his community and the practice of the ancestral ritual with psilocybin mushrooms, of which Maria Sabina was renowned. In recent years, reciprocity and restorative justice are the basis of his work of conducting a needs assessment in his community and developing activities to strengthen the Mazatec bioculture. He is the author of the book Huautla tierra de magia, de hongos y hippies [Huautla land of magic, mushrooms, and hippies] (2014) and the independent magazine, Mirador Mazateco (2010–2015). Osiris seeks to raise awareness about the impact of the Global North on the Mazatec people in this new wave of the psychedelic renaissance. He is Program Coordinator of Chacruna’s Indigenous Reciprocity Initiative of the Americas (IRI).
