Reduces the absorption of cholesterol from the gastrointestinal tract (previously used as a lipid reducer). Sitosterol also reduces the effect of dihydrotestosterone and interacts with the sex hormone binding globulin (SHGB). In this respect, sitosterol was previously used as a remedy for benign prostate adenoma (see also Urticae radix).
