Is Chaga mushroom edible?

Inonotus obliquus (Chaga) is not considered toxic in its traditional use as a tea or extract. However, like many concentrated herbal substances, it can have adverse effects if consumed excessively or by individuals with certain medical conditions. It contains oxalates, which can be problematic for individuals with kidney issues or those prone to kidney stones. There have been rare reports of kidney damage with long-term, extremely high-dose consumption. Chaga can also interact with blood-thinning medications and blood sugar-lowering medications. It is crucial to consult a healthcare professional before regular consumption, especially if pregnant, breastfeeding, on medication, or managing existing health conditions. It is not intended for consumption raw.
