This book calls for an array of wild mushrooms, which are palatable for most people. However, some can cause gastro upset. For example, some people may get a stomachache or other symptoms from eating chicken of the woods. Other people need to be cognizant of potential interactions between a specific fungus and the drugs they are taking. Chaga, for example, may interact with blood thinners or diabetes medication. Wild mushrooms are delicious and interesting foods that you will benefit most from if you take the time to learn a bit about how your body interacts with each species. Take it easy, take it slow, and get to know your mushrooms!
