Coriolus versicolor

Rainbow bracket – This mushroom - used in Eastern Asia for generations - supports the immune system in fighting viruses, bacteria and cancer. "Ötzi" carried a related species in his travel pharmacy 5200 years ago.

The polysaccharides in Coriolus, PSK (Krestin) and PSP, support the body’s immune system, have anti-viral and anti-bacterial properties and a cytotoxic effect on cancer cells.

Various studies performed on cancer patients have revealed that Coriolus can inhibit angiogenesis and metastasis and trigger apoptosis. Coriolus activates the TH 1-immune response, which is why this mushroom is particularly effective counteracting viruses and tumour cells.

More informations about Coriolus

The Coriolus medicinal mushroom has powerful antiviral properties that counteract herpes zoster, flu or cytomegaly viruses. It activates the cell defence and the production of antibodies. In particular HIV- and hepatitis patients experience an enormous improvement in quality of life. However, the mushroom should not be used for the treatment of autoimmune diseases.

Viruses also play an important role in the formation of cancer: Epstein-Barr virus infections increase the risk for lymphomas and breast cancer, while the human papilloma virus (HPV) is suspected to cause cervical cancer. A clinical study verifies that Coriolus can change HPV positive results into negative ones after one year of administration.Similarly, lesions at the uterine orifice regressed during consumption. Thus Coriolus is also a significant fungi in cancer prevention.

"I frequently suffered from flu viruses - sometimes three to four times a year. Nothing helped until I started taking the Coriolus medicinal mushroom. Since then, I hardly ever had the flu again". C. B.


Coriolus has been observed to have antibacterial and antifungal effects on various pathogens (E.coli, streptococci and candida). Coriolus can support in the treatment of canker sores and inflammations of the oral mucosa.

The Coriolus mushroom is particularly implemented before and during radiotherapy. The negative side effects radiotherapy has on blood formation and mucous membranes can be eased, even preventatively. Various studies prove that Coriolus reduces radiation damage in healthy tissue. This is probably due to its antioxidant effects. Its polysaccharides suppress fat peroxidation and intercept other free radicals caused by chemo and radiotherapy. The mushroom activates the body’s antioxidant enzymes such as superoxide dismutase (SOD) and glutathione peroxidase.

Furthermore, individual studies mention Coriolus’ effectiveness in the treatment of hormone-dependent tumours such as breast and prostatic cancer. It is supportive in hormone blocker therapies.

Verified effects from research

  • Can prevent the growth of hormone-dependent prostatic cancer cells. Possibly delays the development of hormone resistance. The PSA value is reduced through an androgen receptor-dependent mechanism.

  • The cell defence is activated: T-, B-lymphocytes, monocytes, macrophages, natural killer cells and myeloid cells are stimulated.

  • The production of antibodies and cytokines (interleukin, interferon, TNF) is promoted.

  • Tumour size can be reduced and cancer cell proliferation can be prevented via inhibiting DNA synthesis. Coriolus has a cytotoxic effect on cancer cells.

  • Antiviral effects were observed for the cytomegalic virus, HIV, herpes and the human papilloma virus (HPV).

  • Coriolus can be used to prevent cancer - especially when exposed to radiation and chemical substances.

  • PSK is capable of inhibiting angiogenesis and thus the spreading of tumours.

  • PSP is capable of triggering apoptosis.
