Turkey Tail
Trametes versicolor · Coriolus versicolor
Turkey Tail (Trametes versicolor / Coriolus versicolor) is one of the most-researched medicinal mushrooms in Asia, particularly in Japan and China for cancer adjunct therapy. Active compounds are PSK (Polysaccharide K, krestin) and PSP (Polysaccharide Peptide) - protein-bound beta-glucans. PSK has been an FDA-equivalent approved adjunctive cancer therapy in Japan since 1977.
Divided doses preferred for cancer adjunct.
Start here. Every protocol below is ordered lowest-first. Begin at the smallest effective dose, hold about a week to assess tolerance, and step up only if needed.
How it works
PSK and PSP drive Turkey Tail's effects:
PSK (Polysaccharide K / Krestin)
Protein-bound beta-glucan that activates immune system via dendritic cells, macrophages, NK cells, and T-cells. Reduces tumor growth in animal models and improves immune function in cancer patients.
PSP (Polysaccharide Peptide)
Similar mechanism, isolated from different Coriolus strain.
Cancer Survival
Japanese trials show improved 5-year survival in gastric and colorectal cancer when PSK is added to standard chemotherapy.
Microbiome
Beta-glucans modulate gut microbiota - prebiotic effect.
What to expect
Days 1-14: subtle subjective effects.
Weeks 2-12: peak immune effects.
Long-term continuous use OK.
