Chaga is an adaptogenic tree fungus that is very popular as an herb in both the East and West. Chaga is rich in antioxidants, trace elements, polysaccharides, beta-glucans, and saponins.

Chaga is traditionally consumed as a tea and is available in various forms; ground into powder or extracted into tincture or freeze-dried powder. Mushroom extracts are typically 10 times more concentrated than powdered mushrooms, and also make absorption easier.
