One clear advantage butea superba has over other herbal testosterone boasters or herbal aphrodisiacs is the degree to which it has been studied. In this respect, it also clearly surpasses tongkat ali (eurycoma longifolia).
What we have with butea superba are phase 3 clinical trials. Phase 3 trials assess the statistically significant efficacy of medications. That’s the kind of studies the health authority of any country wants to see before they grant marketing approval, and the phase 3 trial proves that a chemical substance, or combination of chemical substances, is a remedy for a condition for which pharmaceutical multinationals want to sell it.
Phase 1 clinical studies, by contrast, are designed to test in a few brave volunteer to what extend a certain substance is harmful.
But a phase 1 clinical trial at least deals with humans in a scientific setting.
Below that level, you have experiments with lab rats, or in vitro studies which are conducted with dead tissue in lab dishes.
And then there is bogus science that tests commercial brands to generate marketing hype. That is, for example, what you get for a certain Malaysian tongkat ali brand that claims human trials for their own concoction.
Human studies conducted by sales outfits on their own warez have zero scientific credibility because they cannot be scrutinized. They are baloney. Only studies with generics qualify for proper academic standards. Remember this when you come across human “studies” on tongkat ali searches.
Here now the salient points of a proper butea superba clinical trial, conducted in concordance with rigorous academic standards.
The trial was conducted by Dr. W. Cherdshewasart of the Department of Biology, Faculty of Science, Chulalongkorn University, Phyathai Road, Bangkok 10330, Thailand, and Dr. N. Nimsakul of the
Deja General Hospital, Sriayudhya Road, Bangkok 10600, Thailand
The study was published in the Asian Journal of Andrology in September 2003.
The aim was to study the effect of butea superba on erectile dysfunction in Thai males. A 3-month randomized double-blind clinical trial was carried out in volunteers with erectile dysfunction, aged 30 years to 70 years, to evaluate the therapeutic effect of butea superba tubers.
Abstract: There was a significant upgrading in 4 of the 5 descriptive evaluations of the sexual function questionnaire. Estimation of the sexual record indicated that 82.4 % of the patients exhibited noticeable improvement. Haematology and blood chemistry analysis revealed no apparent change.
Seventeen volunteers in the treated group completed the 3-month trial period. Eight volunteers dropped out between week 2 and 4. Nobody in the placebo group returned to fill out the sexual function questionnaire and receive the second batch placebo capsules since the beginning of week 3.
The background data of the 17 volunteers who completed the course: 40 years to 69 years of age, and 7 were complicated with other systemic diseases.
The complete loss of the placebo volunteers should be the consequence of total uselessness of the tapioca starch used as control placebo, and may imply that there is no psychological effect that could possibly created by the use of the placebo. This then further implies that the patient response to the B. superba capsule should be derived from its pharmacological rather than psychological influence. The trial results were far different from those with sildenafil, which could elicit a high percentage of positive psychological response.
Haematology and blood chemistry analyses showed no significant change. It meant that all relevant functions were not disturbed by 3 months consumption of 1000 mg per day butea superba.
The sexual function questionnaire and records of participants on their sexual conduct indicated a significant improvement in ED patients taking the drug. The authors believe that B. superba may act primarily by increasing the relaxation capacity of the corpus cavernosum smooth muscles via cAMP phosphodiesterase inhibition and may also affect the brain, triggering the improvement of the emotional sexual response. It is interesting to note that patients with additional health problems, such as diabetes mellitus, hyper-tension, heart disease and hyperthyroidism, responded satisfactorily to butea superba.
