Turkey-tail Fungus

Oh Turkey Tail, you are everywhere! Not to mention being a possible therapy for cancer. In China and Japan, a chemical compound extracted from T. versicolor, polysaccharide-K, may be used as an immunoadjuvant therapy for cancer, but this effect is refuted by the American Cancer Society stating that "available scientific evidence does not support claims that the raw mushroom itself is an effective anti-cancer agent in humans." There is no regulatory approval of this mushroom or extract for any clinical use in other developed countries.
