REISHI HISTORY
Reishi is known as Ling Zhi, which means “spirit plant” or “tree of life mushroom” in Chinese spoken word, and the Chinese characters literally translate to “shaman praying for rain.” Those names should give you an idea of how truly powerful the reishi mushroom is. It was seen as such an important herb in ancient times that it can be found in art depicting Emperors and on temple walls in the hands of the gods and goddesses of old.
