As with other autoimmune conditions, medicinal mushrooms can be helpful in cases of psoriasis with one study using an extract of Inonotus obliquus extract reporting a 76% cure rate, with improvement in a further 16% of cases1.

Extracted products delivering high levels of both polysaccharides and triterpenes are preferred. Clinically extracts of Ganoderma lucidum, another mushroom containing high levels of polysaccharides and triterpenes, also show benefit (2-3g/day).
