The immune stimulating compounds found in the medicinal mushroom Coriolus versicolor , known as PSK or Krestin in Japan, generate sales of several hundred million dollars a year, making Coriolus the world's top selling all natural product for serious immune support. Commonly known as the "turkey tail" in North America, Coriolus versicolor (also known as Trametes versicolor), is unique among medicinal mushrooms with extensive use in both Traditional Chinese and Japanese Medicine and modern clinical practice.


However it is critically important when using Coriolus versicolor for health puposes to use it in the "supplement" form. The human body is not capable of absorbing the micro amounts of active constituents, the beta 1-4, 1-3 glucans,contained in Coriolus mushrooms and Coriolus mycelium, both of which are

indigestible. 100 pounds of dry mushrooms or dry mycelium contains only enough active compounds to make three pounds of the powder uused in the clinical studies.
