Plants of the Gods: Hallucinogens, Healing, Culture and Conservation podcast

Wade Davis, celebrated author and anthropologist, joins Mark Plotkin for a personal reflection on the life and legacy of legendary ethnobotanist Richard Evans Schultes. Davis traces Schultes' journey from his transformative encounter with peyote to his decades-long odyssey through the Amazon, where he documented Indigenous sacred plant traditions. Together, they explore how Schultes's discoveries — including his collaborations with mycologist Gordon Wasson and chemist Albert Hoffman — helped ignite the psychedelic era, and how his mentorship of Davis inspired the acclaimed book One River.

The Amazonian Travels of Richard Evans Schultes

Mark Plotkin sits down with Wade Davis — author of One River, Lost Amazon, and dozens more — for a deep dive into one of South America's most misunderstood and miraculous plants. Drawing on their shared history working alongside the legendary Richard Evans Schultes, the two ethnobotanists trace coca from its origins as a sacred, nutritionally rich plant used across Andean and Amazonian cultures to its unjust criminalization driven more by ideology and racism rather than science. Davis also breaks down the differences between the coca leaf, cocaine, and mambe, reflects on lessons from cannabis legalization, and makes a compelling case for why the world should finally embrace coca's extraordinary potential.

In this episode, we're bringing you the second half of our conversation with Dr. Pamela Kryskow.  
 
A co-leader of the largest study on microdosing, she shares what researchers are beginning to understand about how psychedelic plants could treat conditions ranging from Parkinson's disease and chronic pain to existential distress.  But, with so much potential for these plant medicines, there's also the potential for misuse and misinformation. We delve into some of the ways psychedelics could be ethically integrated into patient care, and, what the hospital of the future might look like.
