"The PubMed website, provided courtesy of the U.S. National Library of Medicine and National Institutes of Health, acknowledges studies conducted in Thailand, concerning the positive impact of Butea superba on menís sexual health.
In three separate studies, mentioned on the PubMed website, Butea superba has been shown effective in increasing sperm count, and in the treatment of erectile dysfunction and premature ejaculation. It has also been shown safe for human consumption and topical application.
In the first study, Butea superba was shown to increase the weight of the testes and increase the sperm count in rats. (3) Butea superba was given to the rats at a rate that is 100 times greater than what is recommended by Thailandís FDA for human consumption. Yet, no adverse health effects were seen in the rats that were tested.
For ED patients, improvement was shown in 82.4% of participants. (4) The conclusion of this study indicated that Butea superba appears to improve the erectile dysfunction in ED patients without any apparent toxicity.
The third study of Butea superba suggested that ethanol extracts of Butea superba were effective in enhancing penile erection in rats. (5) The results of the study suggested that this herb might act through the cAMP/cGMP pathways, which are intracellular secondary messengers that play a key role in mediating cellular responses to various hormones and neurotransmitters."
