Increase Sexual Performance

Butea Superba (Red kwao krua) is a twinning wood plant that exists only in Thailand specifically the central, eastern, western and northern parts of Thailand. Butea superba can be found near its cousin Pueraria Mirifica. The roots and stem of Butea superba are medicines used for power, increasing the man’s sexual performance.

Butea superba plant has come to be known as a miracle herb because Butea superba helps to enhance overall human health. Also, Butea superba supports erectile capacity, and improve sensitivity due to its high flavonoid and flavonoid glycoside.

Red Kwao Krua and P. Mirifica Similarities

Both P. Mirifica and Butea superba (the species with which P. Mirifica was at first confused) grow in the same general localities around Chiengmai and appear very similar in the non-flowering (vegetative) state.

The two species can, however, be distinguished by the absence of tuberous roots in Butea superba, and by the flowers which are small and purple-blue in P. Mirifica (but which are only rarely produced except on old plants) and large, red to deep orange, in Butea superba.

Butea superba, for example, is said not to cause breast enlargement (use Pueraria Mirifica for breast enlargement), a fact which suggests that red and white kwao may be distinct botanical species. The term ‘red kwao’ seems current to be used to describe Butea superba, from the roots of which a herbal preparation with reputed anti-impotency properties can be prepared.

However, whether the Butea Superba of antiquity, with tubers described in the pamphlet by Luang Anusar Sunthon as “resembling in shape the tusk or trunk of an elephant”, is identical with Red kwao krua, or is a Pueraria species (either known or not yet formally described) related to P. Mirifica is uncertain at the present time.

Clinical Trials

The effect of Butea superba on erectile dysfunction (ED) in Thai males. Methods: 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.

Results: There was a significant upgrading in 4 of the five detailed evaluations of the IIEF-5 questionnaire. Estimation of the sexual record indicated that 82.4 % of the patients exhibited noticeable improvement. Hematology and blood chemistry analysis revealed no apparent change. Conclusion: The Butea superba plant preparation appears to improve the erectile function in ED patients without apparent toxicity.
