Composition and current knowledge
Chaga is the fungus Inonotus obliquus, which grows on birches in boreal forests. According to a 2023 review, the Khanty of Siberia are said to have used it as early as the 12th century, and Indigenous peoples of Canada such as the Cree, Ojibway and Denesuline also have a tradition of use; a 2025 review lists it among the folk remedies of 16th- and 17th-century Russia and Northern Europe.
Its composition is complex: more than 250 secondary metabolites have been described, including polysaccharides (β-glucans), terpenoids (betulin, lanosterol), polyphenols, sterols and melanin. Clinical data in humans remain insufficient.
| Known compounds | More than 250 metabolites: polysaccharides (β-glucans), terpenoids (betulin, lanosterol), polyphenols (hispidin, phelligridins), sterols, melanin, minerals (Fordjour et al. 2023). |
|---|---|
| Traditional use | Khanty of Siberia (from the 12th century according to a review), Russia and Northern Europe; Indigenous peoples of Canada (Cree, Ojibway, Denesuline). |
| State of research | Mostly laboratory and animal studies; the 2023 and 2025 reviews judge clinical data insufficient. No health claim is authorised for chaga in the EU. |
Good to know
- Chaga is rich in oxalates: a case of oxalate kidney injury was reported in a 69-year-old man after prolonged use of chaga powder (Kwon et al. 2022).
Chaga and its scientific name
GBIF accepts Inonotus obliquus (Fr.) Pilát and places it in the family Hymenochaetaceae, order Hymenochaetales. The name goes back to Fries’ Polyporus obliquus, which GBIF lists as a synonym together with Fomes obliquus and Phellinus obliquus. In Finnish the species is called pakurikääpä, in German Schiefer Schillerporling and in French polypore oblique.
Choosing between chaga products
Chaga from the same Haarlem supplier is also available as whole pieces from Finland and as chaga powder, 100 g. For a second liquid format, the label of the Foodsporen chaga extract states a 12:1 ratio; the Maya bottle gives no ratio. The same bottle and label design is used for the Maya lion’s mane extract.
Storing your botanicals
Keep dried plants in their tightly closed pouch or in an airtight jar, away from light, moisture and heat. Powders absorb moisture easily, so close them again straight away. For extracts, tinctures and capsules, follow the instructions on the label and the printed date.
Before using a plant
- Keep plants out of the reach of children and pets.
- If you are pregnant or breastfeeding, or taking any medication, ask a doctor or pharmacist first: many plants interact with medicines.
- Stop immediately if you have an allergic reaction or feel unwell.
