Chaga (Inonotus obliquus) is a species of mushroom in the Hymenochaetaceae family (Hymenochaetaceae). It is known under the name Chaga (or Tschaga) as a folk remedy against cancer.
Treatment with the extracted active ingredients of Inonotus obliquus was the standard method in the Soviet Union for cancer ailments of all kinds. Teas made from the mushroom are still used in parts of Russia and the Baltic States, and also in Finland and Canada.
Inonotus obliquus is a parasitic wood dweller and causes massive white rot in deciduous trees, especially on various birch trees. The species occurs mainly in mountain forests in the southern range to subarctic regions. The host species of birches are mainly sand birch, Betula platyphlla, Betula davurica, Betula ermani and Korean birch. In addition to birch trees, the fungus also colonizes alder, beech and oak trees. However, Chaga nodules are formed only on birch and alder trees.
The dusky beetle Orchesia cultriformis feeds on hyphae of the crooked chaga fungus.
Inonotus obliquus offers preventing and support of cancer diseases & alleviation of side effects in chemotherapy. Support for skin diseases (psoriasis, rheumatism), lowering cholesterol and strengthening the immune system. Anti-inflammatory & antioxidant, antiviral, metabolism-stimulating, antibacterial, encouraging, cleaning and disinfecting when used externally.
The black tubers of the Chaga spore have been used in Russian folk medicine against cancer since the 15th century. They are known under the name Chaga (Tschaga). There are several reports of its use against cancer in the form of tea from different areas, such as the Olonez Rajon in the Republic of Karelia, Siberia, the Baltic States and Finland. Laboratory and animal tests have confirmed the anti-cancer effect, but clinical trials are still pending. In addition, extracts from the tubers stimulate the immune system, have anti-inflammatory effects, and protect the liver and pancreas. The tubers have always been drunk as a hot water extract.
Inonotus obliquus has over 200 active biological substances. Various polyphenols and especially oxygenated triterpenes have been identified as constituents. Various polysaccharides have been identified as anti-inflammatory substances.
A substrate of birch, corn spindles, wheat bran, soybean, sucrose and gypsum with a moisture content of 65% produced the highest yield of pseudosclerotia in an experiment by Chinese scientists. However, no success seems possible without sophisticated aeration techniques, special culture vessels, and various artifices in fruiting strategy for Chaga mushrooms.
Hobby growers are therefore limited to further cultivation of Chaga on grain to obtain a usable amount of biomass.
Betulinic acid is the magic word, apparently the mushroom cannot get along for long without a certain amount of it.
