Summary: A number of short-term randomised trials and some meta-analyses in the recent literature suggest clinical efficacy and good tolerability for some preparations, mainly extracts from ''Serenoa repens'' and also ''Pygeum africanum'', products with high concentrations of beta-sitosterol, and pumpkin seeds.

Based on these results, the use of phytopharmaceutical agents for the treatment of mild to moderate symptomatic BPH seems to be well justified."

Quotation: "In a randomised, double-blind study, the preparation Curbicin, obtained from pumpkin seeds and dwarf palm plants (''Cucurbita pepo l.'' and ''Sabal serrulata''), was compared with a placebo in the treatment of symptoms caused by prostatic hyperplasia; 53 patients took part in the study, which was carried out over a 3-month period. Urinary flow, micturition time, residual urine, frequency of micturition and a subjective assessment of the effect of treatment were all significantly improved in the treatment group."
