Reishi

Reishi mushroom has been used to help enhance the immune system, reduce stress, improve sleep, and reduce fatigue.

Reishi (Ganoderma lucidum), an oriental fungus, has a long history of use for promoting health and longevity due to its powerful immune modulators. The benefits of reishi mushroom extracts have been demonstrated in thousands of studies.
