Dennis McKenna

Air Date: Wed, 21 Nov 2012

For the last twenty-five years, Dennis McKenna has pursued the interdisciplinary study of ethnopharmacology and plant hallucinogens. He is co-author, with his brother Terence, of The Invisible Landscape: Mind, Hallucinogens, and the I Ching (Seabury Press, 1975; Citadel Press, 1991), a philosophical and metaphysical exploration of the ontological implications of psychedelic drugs which resulted from the two brothers' early investigations of Amazonian hallucinogens in 1971. He received his doctorate in 1984 from the University of British Columbia. His doctoral research focused on ethnopharmacological investigations of the botany, chemistry, and pharmacology of ayahuasca and oo-koo-he, two orally-active tryptamine-based hallucinogens used by indigenous peoples in the Northwest Amazon.

Following the completion of his doctorate, Dr. McKenna received post-doctoral research fellowships in the Laboratory of Clinical Pharmacology, National Institute of Mental Health, and in the Department of Neurology, Stanford University School of Medicine. In 1990, he joined Shaman Pharmaceuticals as Director of Ethnopharmacology. He relocated to Minnesota in 1993 to join the Aveda Corporation, a manufacturer of natural cosmetic products, as Senior Research Pharmacognosist. He currently works as a scientific consultant to clients in the herbal, nutritional, and pharmaceutical industries.
