Research Summary

Chaga has a strong folk tradition as an antioxidant and vitality tonic, and is rich in melanin and betulin-derived compounds. Clinical evidence is limited; preclinical work shows antioxidant and anti-inflammatory activity, but it is not a treatment for cancer, infection, or any disease.

Evidence levels reflect the currently available scientific literature and may change as new research emerges. Where evidence is limited or conflicting, this is stated plainly.
