[Controlled study of the effects of Pygeum africanum extract on the functional symptoms of prostatic adenoma].

Two random groups of sixty patients each were given an extract of pygeum africanum in one group, and a placebo in the other. The results highlight the placebo effect (50 per cent of cases), and that the extract provided an overall improvement in the functional symptoms. The differences between the two treatments were statistically significant for nocturnal frequency, difficulty in starting micturition, and incomplete emptying of the bladder.
