A 3-month randomized double-blind clinical trial was carried out in volunteers with ED, aged 30 years ~ 70 years, to evaluate the therapeutic effect of the crude preparation of Butea superba tubers on ED. There was a significant upgrading in 4 of the 5 descriptive evaluations of the IIEF-5 questionnaire. Estimation of the sexual record indicated that 82.4 % of the patients exhibited noticeable improvement.
The plant preparation appears to improve the erectile function in ED patients without apparent toxicity.
