What is it
Oyster mushroom (Pleurotus species, including P. ostreatus and the king trumpet P. eryngii) is an edible mushroom that naturally contains beta-glucans and the statin-like compound lovastatin. As a supplement or food it is studied mainly for modest effects on blood lipids. Most of its other claimed benefits rest on laboratory rather than human data.

modest blood lipid reduction
Biomarker supportSmall human studies and its natural lovastatin and beta-glucan content suggest oyster mushroom can produce modest reductions in total and LDL cholesterol. Trials are few, small and short, and this is a biomarker change rather than a demonstrated reduction in cardiovascular events. It should be viewed as a minor dietary adjunct, not a lipid therapy.
Bottom line: May modestly lower cholesterol levels, but this is a biomarker effect on weak evidence.

Reasonable as a cooked food; supplement-level extracts lack pregnancy data, so use food forms and consult a clinician.
Interactions
Natural lovastatin content could add to statin effects at high intakes
