According to a 1993 report from Germany, 90% of patients suffering from benign prostatic hyperplasia receive natural therapeutic substances. 50% of German urologists prefer to administer plant extracts instead of synthetic drugs. Of all the plants, saw palmetto is the most widely used. The data on the effectiveness of saw palmetto is impressive. Research results have shown that the natural therapeutic substance derived from this plant has a 90% success rate in treating prostatic hyperplasia, in terms of improving urinary flow, proper bladder emptying, the feeling of pain and discomfort during urination, and avoiding nocturnal enuresis. All benefits were observed within thirty days of taking the plant. The mechanism of action of saw palmetto is not yet clear.

The beneficial effect of saw palmetto is cumulative, and therefore long-term use provides a greater improvement in the patients health.
