Background

Chaga is a fungus that grows on tree trunks, especially birch trees. It produces a woody growth, called a conk, which absorbs nutrients from the wood.

Chaga might stimulate the immune system. It contains some chemicals that have antioxidant effects, and might lower blood sugar and cholesterol levels.

People use chaga for conditions such as heart disease, diabetes, cancer, and others, but there is no good scientific evidence to support these uses. There is also no good evidence to support using chaga for COVID-19.
When taken by mouth: There isn't enough reliable information to know if chaga is safe or what the side effects might be. It contains a chemical called oxalate which can damage the kidneys when taken in high doses for a long time.

Special Precautions & Warnings:

Pregnancy and breast-feeding: There isn't enough reliable information to know if chaga is safe to use when pregnant or breast-feeding. Stay on the safe side and avoid use.

"Auto-immune diseases" such as multiple sclerosis (MS), lupus (systemic lupus erythematosus (SLE), rheumatoid arthritis (RA), or other conditions: Chaga might cause the immune system to become more active. This could increase the symptoms of auto-immune diseases. If you have one of these conditions, it's best to avoid using chaga.

Bleeding disorders: Chaga might increase the risk of bleeding. Don't use chaga if you have a bleeding disorder.

Surgery: Chaga might affect blood sugar control or increase the risk of bleeding during and after surgery. Stop using chaga at least 2 weeks before a scheduled surgery.
