Can Yeast Save Endangered Psychedelics?

The Pharmacy Was Always the Pantry

Dennis McKenna sits down with his old friend Dr. Cedric Baker, an ethnopharmacologist and medical herbalist who studies the ethnobotany of food across more than thirty countries. Together they take apart one of modern medicine's most stubborn assumptions: that food and medicine are separate things. From Thai kitchens where every dish is therapeutic, to the world's longevity hotspots, to the ethics of who owns a plant, it's a conversation that will leave you looking at your own plate a little differently. - - - Cedric Barrett Baker is an ethnopharmacologist, food ethnopharmacognoist, medicinal food ethnobotanist, integrative oncology medical herbalist, pharmaconutrition research scientist, & medical botany, pharmacognosy and pharmacy historian.

Can Yeast Save Endangered Psychedelics?

As the psychedelic renaissance surges, wild sources are collapsing under demand—peyote takes decades to grow, safrole extraction is destroying Southeast Asian forests, and Sonoran Desert toads are being overharvested. In his book Bioengineering Enlightenment, Prof. Jeffrey Gerst proposes a radical solution: engineer yeast or fast-growing plants to produce psychedelic compounds sustainably. But at what cost? Dennis McKenna warns this could strip these substances from their cultural and ecological roots, veering into biopiracy. Together, they debate biotech vs. tradition, exploring alternatives like community-led agroforestry, symbiotic rights, and the “Om Fund” to return profits to Indigenous stewards. They also revisit Terence McKenna’s “Stoned Ape” hypothesis, asking whether paleogenomics could experimentally probe the evolution of human consciousness. - - - Jeffrey Gerst, born and raised in New York, is a Professor of Biology with over three decades of academic experience. He began his career at the Mount Sinai School of Medicine and has since held a long-standing position at the Weizmann Institute of Science in Israel, where he serves as the Besen-Brender Chair of Microbiology and Parasitology. His research focuses on how proteins are correctly localized within cells, particularly through the trafficking of messenger RNA (mRNA), a process essential for normal cellular function and disease prevention. Among his key contributions, Gerst’s work has demonstrated that mammalian cells can transfer mRNA between one another, revealing a novel form of intercellular communication. His lab is now exploring this mechanism as a potential gene therapy approach to treat rare genetic disorders such as Tay-Sachs, cystic fibrosis, and Gaucher’s disease by enabling targeted RNA delivery within the body. In addition to his biomedical research, Gerst advocates for the sustainable production of psychedelic compounds using genetic engineering. He is the author of Bioengineering Enlightenment and has presented this work at major scientific conferences. Learn more about your ad choices.

Terence McKenna, Psychedelics, and the Philosophy of Knowledge

In this rich and thought-provoking conversation, Dennis McKenna speaks with philosopher Mandi Astola about Terence McKenna, psychedelics, epistemology, shamanism, and the nature of knowledge. Together they explore how psychedelic experiences can produce both genuine insight and dangerous overconfidence, why intellectual humility matters, and how science and shamanic ways of knowing can complement each other. The discussion also touches on the “Stoned Ape” theory, the Timewave, the trickster archetype, and the role of psychedelics as tools for understanding reality, consciousness, and human evolution. A fascinating dialogue for anyone interested in philosophy, altered states, ethics, and the limits of what we know. - - - Mandi Astola is a philosopher specializing in epistemology, ethics and ethics of technology. She is assistant professor at Delft University of Technology's philosophy section.  In particular, Mandi's work focuses on character and what features of character make someone a good person, or a good thinker. She is also part of a project, involving multiple universities, that investigates the contribution that various disciplines in the arts can make to ethical reflection on new technologies.
