Dennis Jon McKenna is an American ethnopharmacologist, research pharmacognosist, lecturer and author. He is the brother of well-known psychedelics proponent Terence McKenna and is founding board member and the director of ethnopharmacology at the Heffter Research Institute, a non-profit organization concerned with the investigation of the potential therapeutic uses of psychedelic medicines.

He is also one of the founding contributors to the modern wave of ayahuasca research in particular and psychedelic research in general. In fact, the book Magic Mushrooms grower’s guide, which he co-authored with his brother Terence in the 70s, presented the first reliable method for cultivating psilocybin mushrooms at home.

Chances are if it wasn’t for Dennis and his brother, none of us would have ever tasted the magic at all.
