If this describes you, you can, instead, forage for medicinal mushrooms in your local grocery store’s produce aisle!   An example is those ubiquitous white button mushrooms found at most grocery stores…A large population study concluded that eating just a small amount of them regularly is linked  a reduced incidence of breast cancer. 

Learn the medicinal qualities of Buttons, Cremini, Portabellas, Shiitake, Maitake, and Oyster Mushrooms with some recipes for incorporating them into your life. (Note:  3 of these are actually the same species!)

Mushroom season will be here before you know it.
