Mushrooms have traditionally been valued in Asia for their nutritional and medicinal qualities. The Coriolus versicolor or "Turkey Tail" mushroom has been investigated in numerous laboratory, animal and human clinical studies. Most of these studies have demonstrated that it does appear to have significant antimicrobial, antiviral and antitumor properties when used as a supplement to chemotherapy and/or radiotherapy.
