Inonotus Obliquus

Common Names: Chaga, Clinker Polypore









Chaga mushroom, also known as the "King of Medicinal Mushrooms," grows predominantly on birch trees in cold climates such as Northern Europe, Russia, Korea, and parts of Canada and the United States. Historically, Chaga has been used for centuries in Siberia and other parts of Asia as a traditional medicine to boost immunity and overall health. It was also popular in folk medicine for a variety of ailments, ranging from gastrointestinal issues to skin conditions. Foraging for Chaga involves identifying the right trees (typically older birch trees) and looking for the distinct black, charred-like appearance of the Chaga conk that protrudes from the tree bark. The part of Chaga used medicinally is the dense black mass that is visible on the outside, while the interior is a rusty yellow-brown. It is crucial to harvest Chaga sustainably, ensuring not to overharvest from any single tree and to allow time for the fungus to regrow. Chaga is rich in a complex array of bioactive compounds including antioxidants, polysaccharides (such as beta-glucans), triterpenoids, and melanin, a pigment that is known for its protective effects against radiation and oxidative stress. These compounds contribute to Chaga’s reputation as an immune modulator, as well as its anti-inflammatory and liver-protective properties. Studies have suggested that Chaga can help in boosting the immune system, reducing inflammation, and even fighting cancer cells. The antioxidant properties are particularly noteworthy, with Chaga demonstrating higher levels of antioxidant activity than other well-known superfoods like blueberries.

Choosing the Right Products

Check whether Wild or Cultivated Mycelium:

Wild will be more potent, but cultivated is much more sustainable. If cultivated verify seller has testing for beta-glucan / triterpene levels.

Oxidative Stress

Chaga mushroom (Inonotus obliquus) is a powerful natural remedy known for its exceptional antioxidant properties, making it highly effective in combating oxidative stress. Rich in bioactive compounds like polysaccharides, melanin, and superoxide dismutase, Chaga helps neutralize harmful free radicals in the body, thereby protecting cells from damage and reducing inflammation.

Injury Recovery

Chaga is one of the most antioxidant-rich foods on the planet, and helps to stimulate the most powerful antioxidant in the body: superoxide dismutase, which helps to protect against oxidative stress. Exercise, especially intense or long-duration forms, creates a lot of free-radicals in the body which can cause damage, and Chaga mushroom with its antioxidant powers can help to combat this. Anti oxidents have also been shown to help with injury recovery.

  • Chemical analysis, moisture-preserving, and antioxidant activities of polysaccharides from Pholiota nameko by fractional precipitation

  • This study explored Pholiota nameko (P. nameko) polysaccharide fractions, PNP-40, PNP-60, and PNP-80, purified by gradient concentrations of ethanol (40%, 60%, and 80% (v/v)). The physicochemical properties, functional group composition, moisture-preserving, and antioxidant ability were determined. The results indicate that the polysaccharide contents of PNP-40, PNP-60, and PNP-80 are 45.12%, 78.04%, and 72.22%, respectively, while the β-glucan, protein, and uronic acid contents are 20.20%, 12.20%, and 10.15%, respectively; 11.24%, 14.53%, and 26.94%; and 5.99%, 7.73%, and 3.78%. Furthermore, PNP-60 has better moisture absorption, while PNP-80 has better antioxidant ability and H2O2-injury resistance activity

  • In May 1950 my husband undertook a pilgrimage to remote Serignan to see the Fabre water-colors, and he picked out more than a dozen for our book. Two years later, finding himself again in Paris, he called once more on Professor Heim, who by now had become the Director of the Museum National, a worthy successor in that great post to the illustrious Buffon. Indeed, he sits at Buffon's very table, in Buffon's very room, where the elegant i8th century furnishings have remained unchanged, the walls adorned with the graceful i8th century oils of Jean-Jacques Bachelier, depicting the birds of the several continents.


  • THIS book is addressed to those who love mushrooms, who love the whole rich world of wild mushrooms in the same way that many love the flowers of the field and the birds of the air. Our public is certainly one of the smallest in the English-speaking world, but no matter. We invite all to share our joys, and if few respond, we are not less happy for being few to savor the secret.
