Mushrooms have been used as medicine for thousands of years, in every region of the world where they grow. After decades of study, mycologist and clinical herbalist Christopher Hobbs profiles ten of the most powerful medicinal mushrooms and explains the research behind why they work. Exploring the health and healing benefits provided by mushrooms' nutritional and medicinal compounds, Hobbs details how to select fresh and dried mushrooms as well as instructing readers in growing their own or safely foraging in the wild; proper storage; how recipes for preparations that activate each mushroom variety's medicinal compounds. Whether readers are growing or foraging their own or sourcing them from a local provider, they'll turn to this handbook as their guide to making health-boosting mushroom medicine.
