The appearance of Chaga is reminiscent of an area of bark that has irregular furrows, a broken, bulbous shape and looks as if it has been burned. Its external and internal use has a tradition dating back centuries. According to legend, the Grand Prince of Kievan Rus’, Vladimir II Monomakh, who lived in the 11th/12th century, was cured of cancer of the lower lip due to a broth made from Chaga. The mushroom traditionally helps to heal wounds, burns and skin inflammation. It is also used for inflammatory gastro-intestinal illnesses such as gastritis or peptic ulcers as well as malignant tumours.

Applications tested in practice

• Cell-protecting potential

The antioxidant, cell-protecting potential of Chaga can be attributed both to the beta-glucans it contains and other polysaccharides as well as to the active substance betulin. The latter is also interesting for prevention, as the substance can trigger the production of interferon, whereby the cellular mutation rate is reduced.

• Inflammation reduction, soothing and stabilisation for inflammatory gastro-intestinal illnesses, peptic ulcers, chronic gastritis, ulcerative colitis

A great deal of research indicates that Chaga can help with inflammatory disorders of the digestive tract – due to the beta-glucans, which have anti-inflammatory, antibacterial and antiviral properties. In addition, betulin can also have an anti-inflammatory effect.

• Promotion of wound healing

It is presumably the interaction of beta-glucans and melanin, which are known to have photoprotective properties, that accounts for the ability of Chaga to protect against melanoma. Chaga can not only be used as natural skin protection, but also used alongside radiotherapy for tumours.

• Use as a general tonic

Above all in traditional Chinese medicine, Chaga is considered a proven tonic with both a stimulating and balancing effect.
