OBJECTIVE: To review and evaluate the literature relative to the use of herbal therapies in the treatment of benign prostatic hyperplasia. DATA SOURCES: Literature was identified by MEDLINE, Embase, International Pharmaceutical Abstracts, and the International Bibliographic Information on Dietary Supplements searches and through cross-referencing of selected articles. STUDY SELECTION/DATA EXTRACTION: All articles identified from the data sources were evaluated and all information deemed relevant was included in this review. DATA SYNTHESIS: A large percentage of men >50 years old begin to experience signs and symptoms of benign prostatic hyperplasia (BPH). Herbs hold promise in the treatment of BPH. Serenoa repens, Pygeum africanum, Urtica dioica radix, and Cucurbita peponis semen are some of the botanical therapies used in the treatment of BPH. CONCLUSIONS: There are many European studies examining efficacy, dose, and adverse effects of these plants in the treatment of BPH. However, numerous questions remain. These include issues concerning long-term beneficial and adverse effects of herbal therapy, prevention of complications, standardization of extracts, and concomitant use with "mainstream" medications. Based on the information available today, these botanical therapies can be used for treatment of a number of objective and subjective symptoms in patients with BPH, stages I and II.

Sixty patients in Stages I and II of benign prostatic hyperplasia were treated with Peponen capsule. Out of them 26 took the drug for 10 months, 22 for at least 7, and 12 for at least 4 months. The daily dosage was 3 x 2 capsules in the first month and 3 x 1 capsule for the rest of the time. On the ground of urodynamic test results and changes in subjective complaints, more than 80% of the patients experienced improvement. The therapy intensified the uroflow, appeased dysuria, the difficult and painful discharge, and reduced the frequency of nocturnal urination.
