Known as the “Cloud Mushroom” in Asia and “Turkey Tail” in North America because of its unique shape, Coriolus is one of the most thoroughly studied medicinal mushrooms supplementing liver(1), respiratory(2) and immune system(3) conditions.  Naturally equipped with chemically distinct peptides(4) known as the “biological response modifier”(5), the Coriolus mushroom has been proven to have potent immunomodulating capabilities contributing to a healthier life.

Active Constituents:

The Coriolus mushroom contains beta-D-glucan, triterpenoids, monosaccharides and glyconutrients which is believe to be the key resulting to its extraordinary health beneficial effects.  A combination of these compounds found in the Coriolus mushrooms are nowadays known by the Scientists and clinicians as PSK(6) and PSP(7), both are active extracts from the mycelium of the mushrooms.
