wild chaga Inonotus obliquus mushroom

Japanese name – Kabanoanatake

Chinese name - Bai Hua Rong

English name – Chaga

I. obliquus grows widely in the forests of Eastern Europe and Russia on several trees, including birch, alder and spruce, where it appears as a sterile growth or conk on the trunk of the tree. The fruiting body is reported to be found growing nearby but is extremely rare in nature.

Traditionally only the I. obliquus growing on birch trees was used, as a tea in the treatment of cancers including inoperable breast cancer, hip, gastric, parotid, pulmonary, stomach, skin, rectal and Hodgkins disease1 and I. obliquus is recorded as a miraculous cure for cancer in Solzhenitsyn’s semi-autobiographical 1967 novel, the “Cancer Ward”.

The wisdom of using birch grown I. obliquus is supported by the finding that one of its key components is the triterpene betulinic acid, which occurs naturally in a number of plants but primarily in the bark of the white birch (Betula pubescens – seen as the tree of life and fertility in many Eastern European and Siberian myths) from which it gets its name. I. obliquus growing on the birch trees takes up high concentrations of betulinic acid from the bark of the trees, making it and its derivatives available in an absorbable form.

Betulinic acid has been shown to induce mitochondrial apoptosis in different cancer cell lines and inhibit the enzyme topoisomerase2, which is essential for the unwinding and winding of the DNA strands in cell replication. In addition it possesses anti-retroviral, anti-parasitic and anti-inflammatory properties3. It is currently being developed as an anti-cancer agent through the Rapid Access to Intervention Development program of the US National Cancer Institute and is also a major contributor to the anti-cancer action of mistletoe4.

Other important components of I. obliquus include polysaccharides and sterols. Its high phenolic content gives it exceptional antioxidant properties and a melanin complex has also been identified as having significant antioxidant and genoprotective properties 5,6.

Like most other medicinal mushrooms, Reishi contains compounds of the chemical group called Beta-Glucan (in particular, 1,3 (8) 1,6 beta glucan). This has been shown by the overwhelming majority of scientific studies to be very potent.(1) In fact, Reishi contains more Beta-Glucan than any other mushroom yet tested, up to 40% by weight in some samples.

Widely used in Poland and Russia as a folk remedy against cancer7, I. obliquus is now attracting increasing interest among practitioners with its combination of immune supporting polysaccharides and components with direct anti-cancer activity, especially betulinic acid derivatives.

In vitro studies on betulinic acid have shown it to be highly effective against a wide variety of cancer cells: human melanoma, neuroectodermal (neuroblastoma, medulloblastoma, Ewing’s sarcoma” and malignant brain tumours, ovarian cancer, human leukaemia HL-60 cells and malignant head and neck squamous cell cancers, including those derived from therapy-resistant and refractory tumours8,9. However, it was found to have no effect on epithelial tumours, such as breast cancer, colon cancer, small cell lung cancer and renal cell cancer as well as T-cell leukaemia cells. Its anti-tumour activity has been related to its direct effects on mitochondria and induction of apoptosis, irrespective of cells p53 status10.

Clinically betulinic acid’s action against brain cancer cells is particularly interesting and it is noteworthy that in one study it exerted cytotoxic activity against primary tumour cells cultured from patients in 4 of 4 medulloblastoma-tumour samples tested and in 20 of 24 glioblastoma-tumour samples11. It also shows great promise in combination with radiotherapy, exhibiting a strictly additive mode of growth inhibition in combination with radiation in human melanoma cells in one study and acting as a radiosensitizer in head and neck squamous cell cancers in another12,13.



In vivo studies confirm its anti-cancer action as well as a complete absence of systemic toxicity in rodents8.

ANTI-VIRAL – I. obliquus has traditionally been used to treat a number of viral conditions and betulinic acid analogs have been shown to disrupt assembly and budding of the HIV-1 virus and viral fusion to the cell membrane9.
