Reishi

Reishi is a tree fungus that has been used in Asia for thousands of years, where it is considered an adaptogenic "elite herb" on par with, for example, ginseng and schisandra. Reishi is traditionally consumed as a tea or extract, 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.
