Jeff Chilton studied Ethnomycology at the University of Washington in the late sixties and in 1973 began a 10 year career as a large scale commercial mushroom grower. In 1989 Jeff established Nammex, the first company to supply medicinal mushroom extracts to the US Nutritional Supplement industry. Nammex extracts are used by many supplement companies and are noted for their high quality based on scientific analysis of the active compounds. Jeff joined Sarah and Russ to talk mushrooms and shared some his secrets only for our listeners.
