We’re talking mushrooms with mushroom legend, Jeff Chilton.  Jeff has spent close to 50 years in the mushroom industry and is a true wealth of knowledge when it comes to fungi.  Jeff and I discuss medicinal mushrooms, edible mushrooms, magic mushrooms and what to specifically look for when sourcing mushrooms.

scientific analysis of the active compounds.
