PSK & PSP Extractions

PSK  & PSP Extraction

Historically, Coriolus was picked, dried and steeped in boiling water and drunk as a tea to gain access to its properties. Today, PSK is extracted using a  hot water/ethanol process using the fruit bodies of the mushroom. This provides a capsulated form of the PSK component of the mushroom which can be taken orally.

Real PSP is Never Produced From Fruit Bodies

Published scientific studies of PSP have used only extracts derived from the mycelia stage of the mushroom lifecycle, not extracts from fruitbodies (mature mushrooms). The PSP extracted from mycelia is chemically different to extracts from the fruit body later in the mushroom lifecycle. There are differences in monosaccharide composition (PSP has Galactose) and protein composition (PSP has peptides).
It is the chemical composition of PSP from mycelia that has been the subject of scientific research.

The only known process capable of producing the pure and potent Coriolus Versicolor mycelium needed as the raw material for research-quality PSP is to extract from mycelia produced through deep layer cultivation in pharmaceutical grade sterile production facilities.

Recently a mycelium stem extraction has produced a higher potency of both PSK and PSP extractions. This has been difficult to obtain in the US but is now available. See Where To Buy Best Coriolus Page.
