Maitake mushroom growing on a log in the wilderness.

Maitake (Grifóla frondosa) is also known in Japan as ‘dancing mushroom’ and in Europe as ‘hen of the woods’, since its frond-like growths resemble the feathers of a fluffed chicken. Maitake has a long history of traditional use as a food and potent adaptogen that enhances immunity, builds endurance, reduces fatigue, and is useful in treating arthritis, hepatitis, viral illness and some cancers. Limited animal and preclinical studies along with popular use suggest the ß-glucan and polysaccharide constituents in maitake exert anti-diabetic, anti-hypertensive, anti-neoplastic and anti-viral effects with anti-tumor effects arising from stimulating apoptosis (programmed cell death) and enhancing immunity.
