Most of the active polysaccharides are found in the cell walls of the mycelium and the fruitbody (mushroom), and are water soluble and hot-water extractable.

Alcohol is used to precipitate the water- extracted polysaccharides, and control the heat. Alcohol is never used alone.

Our extracts are more potent than a less-expensive, hot-water only extracted product. The alcohol precipitation yields both polysaccharide and protein bound polysaccharide in the extract.

Products extracted with only hot water are lacking in protein-bound polysaccharides historically researched and proven to be necessary for maximum effectiveness.

This is particularly important for the extracts of Coriolus known as PSP and PSK.
