In this episode, Geoffrey Woo sits down with Dr. Dennis McKenna, a research pharmacognosist, lecturer, author and a founding board member and director of ethnopharmacology at the Heffter Research Institute concerned with the investigation of the potential therapeutic uses of psychedelic medicines. Dr. McKenna discusses his own history in becoming interested in psychedelics, including his experiences in the Amazon with ayahuasca and plant medicine. We also discuss psychedelics as therapeutics, their traditions, and the historical and mechanistic overlap between psychedelics and fasting.
