Coriolus PSP (Coriolus versicolor) from MushroomScience™
Supports Immune Function*
Dosage:  400 mg
Size: 90 Capsules
Category: JHS Products / Mushrooms
  Product Number: JHS-PSP90
Product Code: JHS-PSP90

PSP Polysaccharide-Peptide
Polysaccharide-peptide is a recent addition to the family of medicinal-mushroom-extract products. Developed in China, extensive clinical testing did not begin until the early 1990s.

Under NMR analysis the glucan portion of PSP is almost identical to that of PSK® and VPS®; however, due to variations in fermentation media and extraction methods, there are some differences. PSP contains arabinose and rhamnose as single sugars but no fucose. The material used in the Japanese research (PSK®) and VPS® contains fucose, but no arabinose. Also, PSK® and VPS® contain protein in the non-polysaccharide portion of the molecule, PSP contains peptides.

Immune modulation.*

Clinical Research
All clinical research has focused on the immuno-modulating* properties of the polysaccharide-peptides.

Toxicity, Cautions, Contraindications
Coriolus polysaccharides are safe and nontoxic, having been used daily in clinical studies lasting five to ten years. However, immuno-modulating substances should be used with extreme care or avoided completely in organ-transplant patients utilizing immuno-suppressive agents.

Active Constituents
Polysaccharide-Peptides ( 1-4,1-3)

Extraction Information
The active constituents, the polysaccharide-peptides, are found in the cell walls of both the fruit bodies and the mycelium. Extraction with hot water, followed by precipitation with ethanol, is used to isolate the polysaccharide-peptides. This product is an intracellular mycelial extract from the Cov 1 strain of Coriolus versicolor. The mycelium is grown on an all-natural, chemical-free nutrient base and is produced through the deep layer cultivation method, yielding the most bioactively potent mycelium for raw material.


Coriolus versicolor belongs to the family Polyporaceae and is found throughout the wooded temperate zones of North America, Asia, and Europe. Found predominantly on hardwoods, the thin, woody, shelf-like fruit bodies form dense overlapping clusters on the sides of stumps and fallen trees. The fruit bodies (mushrooms) have a plush, velvety surface, are colored in varying shades of gray or brown, and have a distinctive pattern of alternating bands of dark and light color. The bottom is cream colored and porous.

Suggested Usage: Take 1-3 capsules twice times per day, after meals.

Other Label Information:  Keep out of reach of children. Do not use if pregnant or breast feeding. Do not use if hypersensitive or allergic to mushrooms. Do not use if safety seal around top of bottle is missing or broken. Store at room temperature with lid tightly closed.
