Detailed information

Willowherb extract in benign prostatic hyperplasia

Plant active substances cannot reverse benign prostatic hyperplasia (BPH), but they can exert a strengthening and invigorating influence on the weakened urinary organs and significantly improve symptoms (1).
The phytosterols contained in willow herb such as β-sitosterol, curcubitin and various bioflavonoids have a stabilizing effect on the prostate metabolism. The antiprostatic mechanism of action is not yet known, but it is certain that sitosterols have antiphlogistic and antiedematous effects. Overall, the symptoms of incipient BHP can be improved by these plant extracts (2). Willow herb contains phytosterols as well as querceting glycosides, which are among the main active substances relevant for this indication (1).
