Pleurotus ostreatus
A widely cultivated medicinal mushroom with cholesterol-lowering lovastatin and immune-stimulating beta-glucans.
Oyster mushroom (Pleurotus ostreatus) is a widely cultivated edible and medicinal mushroom known for its cholesterol-lowering, immunomodulatory, and antioxidant properties. Its key bioactive compounds include lovastatin (a natural statin), beta-glucans, and ergothioneine, which contribute to its therapeutic effects. Evidence is primarily from preclinical and small clinical studies, supporting its use in hyperlipidemia, immune support, and glycemic control.
The cholesterol-lowering effect is primarily attributed to lovastatin, which inhibits HMG-CoA reductase, reducing endogenous cholesterol synthesis. Beta-glucans (1,3/1,6-β-D-glucans) activate immune cells such as macrophages, natural killer cells, and dendritic cells via dectin-1 and complement receptor 3, enhancing innate and adaptive immunity. Ergothioneine acts as a potent antioxidant, scavenging reactive oxygen species and protecting against oxidative stress. Additionally, polysaccharides may improve insulin sensitivity via modulation of PPAR-γ and GLUT4 expression, contributing to antidiabetic effects.
