Chaga (Inonotus obliquus) is a highly awarded tonic fungus (mushroom), long used in traditional Siberian, Korean, Chinese, north European and Scandinavian herbalism. It is found growing wild in old forests throughout the colder regions of Northern Asia and Northern Europe. The ultimate Chaga is believed to come from sub-arctic Siberian birch tree forests. TLCs Siberian Chaga is 100% Pure Extract, collected from remote sub-arctic Siberian forests. Chaga is known for its very high content of super-oxide dismutase (SOD), an important enzyme that functions as a powerful antioxidant. SOD performs a vital antiaging function by neutralizing oxygen free radicals, preventing oxidative damage to cells and tissues. In studies, low tissue levels of SOD have been associated with both a decline in overall health and a reduction in life span. Looking even further into its use, we have come to learn that in much of Siberia, Russia, and Eastern Europe, it is an essential beverage.
