Inonotus obliquus known as Chaga mushroom
Is a fungus in Hymenochaetaceae family. It is parasitic on birch and other trees. The sterile conk is irregularly formed and has the appearance of burnt charcoal. It is not the fruiting body of the fungus, but a mass of mycelium, mostly black due to the presence of massive amounts of melanin. The fertile fruiting body can be found very rarely as a resupinate fungus on or near the clinker, usually appearing after the host tree is dead.I obliquus grows in birch forests of Russia, Korea, Eastern and Northern Europe, northern areas of the United States, in the North Carolina mountains and in Canada,,,,
Chaga is traditionally grated into a fine powder and used to brew a beverage resembling coffee or tea. For medicinal use, an extraction process is needed to make at least some of the bio-active components bioavailable. These bio-actives are found in the mostly indigestible chitin cell walls of the chaga. Humans lack the enzyme chitinase, so cannot fully digest raw mushrooms or their derivatives, and the digestive process works too fast for the stomach acid to take effect. Scientific studies and research are in general also based on highly concentrated extracts, and traditional Russian usage is also based on a form of hot-water extraction
Currently, three extraction processes are used, each with a different outcome.
Hot water extraction is the most common and the cheapest method. It can be compared to the traditional tea-making process. All water-soluble components will be present in the resulting extract. Water-insoluble components, such as phytosterols, betulinic acid and betulin, will be absent. Several extraction rounds combined with modern pharmaceutical techniques can result in high levels of polysaccharides, up to almost 60%. The ß-D-glucans, the bio-active part of these polysaccharides, might add up to ±20 %. Polyphenolic components are water-solubles and will also be present.
Ethanol or methanol extraction isolates the water-insoluble components, betulinic acid, betulin and the phytosterols. This extraction process is in general used as a second step after hot-water extraction, since ethanol alone will not break down chitin effectively - heat is essential.
Fermentation is the most time-consuming, so is the most expensive; this method is not used very often. Because fermentation methods are not standardized many types of bacteria and fungi can be used in the process, the outcome is also not standardized.
Extracts with a therapeutic value usually combine two methods, usually hot water and ethanol extraction. This will result in all bioactive components being present. Cheap, mass-produced extracts are in general hot water, low percentage (4-20%) polysaccharide extracts with limited therapeutic value. The information on the supplements' label will usually reveal inclusion or exclusion of components. However, the majority of mushroom dietary supplements that are sold are non-extracted, being the cheapest option. To achieve at least some therapeutic effects the consumer has to make a tea from it.
