Oyster mushroom is an edible fungus found widely in North America and Europe. It is used in traditional medicine to treat infections, hyperlipidemia, diabetes, and cancer.
In vitro experiments and studies done in mice have shown that Oyster mushroom has antitumor (1) (7) (8) (9) (12) (13), immunomodulatory (10) (11), antifungal (2), lipid lowering, and hypoglycemic (3) (6) properties. The beneficial effects are due to the polysaccharides, lectins, and peptides present in Oyster mushrooms.
A pilot study sponsored by the National Center for Complementary and Alternative Medicine was conducted to determine the lipid-lowering effects of Oyster mushrooms in patients with AIDS and hyperlipidemia, but the data have yet to be published (5).
No adverse effects have been reported from consuming Oyster mushroom.
