Trametes versicolor, the mushroom from which PSK was isolated.
Polysaccharide-K (Krestin, PSK) is a protein-bound polysaccharide, which is used as an anticancer immunologic adjuvant in some countries.
PSK is isolated from the fruitbody of Trametes versicolor. Preliminary evidence indicates PSK has anticancer activity in vitro,[1] in vivo[2] and in human clinical trials.[3] Preliminary research has also demonstrated that PSK may inhibit various cancer onset mechanisms.[4] Preliminary evidence indicates PSK may have use as an adjuvant in the treatment of gastric, esophageal, colorectal, breast and lung cancers.[5] Human clinical trials suggest PSK may affect cancer recurrence when used as an adjuvant,[3][6] and basic research has demonstrated it inhibited certain human cancer cell lines in vitro.[7][8][9]
The MD Anderson Cancer Center reported that it is a "promising candidate for chemoprevention due to the multiple effects on the malignant process, limited side effects and safety of daily oral doses for extended periods of time."[10] The Therapeutic Goods Administration in Australia reported that the WHO has only eight records of adverse effects with PSK and none reported for PSP.[11]

Research summary
In conjunction with chemotherapy, PSK has increased the survival time of cancer patients in randomized, control studies, with stomach cancer (meta-analysis of 8,009 patients),[3] colorectal cancer (randomized, controlled study of 448 patients),[12] non-small cell lung carcinoma,[13][unreliable medical source?] and small cell carcinoma of the lungs.[citation needed] PSK has produced mixed results with breast cancer,[14][unreliable medical source?] liver cancer,[15] and leukemia.[16][original research?]
PSK chemistry
PSK is a protein polysaccharide consisting of a beta-glucan β-1,4 main chain with β-1,3 and β-1,6 side chains. The approximate molecular weight of PSK is 100,000 Da, and the protein component is reported at the β-1,6 side chain.[4] PSK is isolated from the "CM-101" strain of Trametes versicolor. The analogous compound PSP, is derived from the "COV-1" strain of Trametes versicolor.[5]
