Naturally grown on mulberry trees, the Phellinus linteus mushroom  (also known as the Meshimakobu mushroom and Sang Hwang) is a rare medicinal mushroom that has been used in oriental medicine practices.  The overall health benefits include to stimulate the hormonal (1) and cell-mediated (2) immune function and to maintain a normal blood glucose level (3)

Active Constituents:

The Phellinus mushroom extracts consist of three different parts:   Beta D-Glucan and lectin (The polysaccharide-protein complexes) found in the mushroom were shown to have immunomodulating effects (4). The polyphenolic components of the extracts demonstrated potentials protect against free-radical related injuries in animal models (5).  Finally, the most recent discovered constituent, known as the interfungins A, help with protein synthesis during glucose metabolism, which may help diabetics supplementing their daily nutritional management programs.
