Chaga extract comes from a birch tree fungus. This concentrated herbal preparation features in traditional wellness.
Common forms include liquid tinctures and powdered extracts. People mix them into tea, coffee, or smoothies.
Limited human research exists on chaga. Lab tests show potential antioxidant activity, but clear health benefits remain unproven.
Chaga may affect blood clotting and blood sugar. It can interact with blood-thinning medications. People with autoimmune conditions, diabetes, or upcoming surgery should consult a healthcare provider before use.
