There are many mushrooms used therapeutically in the herb community with Reishi (Ganoderma spp.) being the the best known.
One of the challenges to effectively using these gifts from the fungal world is knowing how to process them. While plants have cellulose, mushrooms have chitin. This substance is extremely hard and makes extraction difficult. The usual methods of making teas and tinctures don’t work.
