Essential facts for the medicinal and traditional use of mushrooms as supplements and food, a health trend that started thousands of years ago. Author, scientist, and public health advocate Jonathan Fredette working in the OHSU Department of Pathology Laboratory gained valuable insight into allopathic medicine and laboratory sciences. Pursuing mushroom research and cultivation using his knowledge and experience to focus on medicinal applications, he then educated others through his cultivation workshop series, local events and online community meetups. In six laminated pages Jonathan created a succinct reference covering the most useful and well known mushrooms with essential facts including medicinal uses and properties, dosing and cautions, and even mushrooms to avoid. With more valuable facts per page than any other source this inexpensive tool can open a world of options for maintaining wellness or addressing health issues with natural and powerful fungi.
