Chaga, scientifically known as Inonotus obliquus, is a parasitic fungus that grows on tree trunks, particularly those of birch trees. It can be found growing along the northern latitudes of Russia, Scandinavia, Korea, Japan, United States and Canada.

Predominantly, it is found growing in the cold Taiga forests.


The indigenous Siberians have used chaga for thousands of years and there is a long history of chaga being used in folk medicine for treating cancer, gastritis, ulcers and tuberculosis in Russia and northern Europe.
