Butea superba, also called Red Kwao Krua is an herb native to Thailand. Butea Superba, or locally known as Red Kwao Krua in Thailand is a plant herb in the family Papilonaceae. This plant has the characteristics of being a crawling vine that wraps itself around large trees. Many species of this plant exist. Through an arduous research effort two species were selected for commercial cultivation.

The roots and stem of the plant are medicines used for strength and power for centuries, and it has been revered as a health tonic. They are used for medical research, health supplements as well as for beauty treatment.

The tuberous roots of Butea superba were found to contain flavonoids and flavonoid glycosides as well as sterol compounds, including β-sitosterol, campesterol and stigmasterol.

Although there are chemical similarities to Pueraria Mirifica (White Kwao Krua) these two plants are very diverse in their chemical attributes. The Red Kwao Krua is the herb used by males and the White Kwao Krua (Pueraria mirifica) is the herb used by females. White Kwao Krua has a high concentration of phytoestrogens, while Red Kwao Krua is used by males and has aldosterone, which is a natural hormone, thought by locals to be an aphrodisiac.

Butea superba is abundantly distributed in the Thai deciduous forest and has been popular among Thai males for its supposed effects on rejuvenation and sexual vigor. It has a molecular structure that makes it a natural PDE 5 inhibitor making it a perfect natural male enhancer.

With the research effort it has been established that Butea Superba does facilitate vasodilation in the utilizing similar mechanisms as the prescription drug rejuvenate herb. Subjects also report an increase of energy without an increase in nervous system stimulation. Butea Superba has been used safely with no known side effects. According to research, this herb can be utilized as a mild alternative aphrodisiac.

Butea Superba or Red Kwao Krua has demonstrated multiple health benefits in several studies concentrating on its benefits toward male health. Derived from colonel selection, the cultivar with the highest flavonoid and flavonoid glycosides have been selected and grown via organic farming.

The raw extract from the root of Butea Superba contains flavonoids and flavonoid glycosides demonstrating comparable benefit as that of any commercial male enhancing pill, without any of the side effects. Studies have showed that high flavonoid and flavonoid glycoside content may support blood flow to male genitals, may promote normal sexual function and erectile capacity, and enhances sensitivity and performance.

Studies also revealed a strong vasodilatation effect, via production of nitric oxide. Enzymatic tests have shown Butea Superba to be a potent inhibitor of c-AMP Phosphodiesterase which reacts directly at the corpus cavernosum in the penis enhancing blood flow to that area creating a more frequent, longer lasting, stronger male sexual arousal period.

Butea Superba is used as a sex enhancer in Asia by middle-aged and older men as a tonic and virility enhancer. One human trial shows Butea Superba can improve erectile function in males. Studies done on rodents showed that when Butea Superba (the frondosa koen species) was given to male rats, they mounted female rats more often and they also ejaculated more frequently. In addition, the roots and stem of the plant are considered to help increase male sexual performance. Thus, this plant has come to be known as a miracle herb. Since Butea Superba helps to enhance human health, it was considered to be an essential factor to entity the chemical constituents of this herb.

One study indicates that Butea Superba has some anticholinesterase activity. This would mean that Butea Superba can increase levels of acetylcholine in the body. Acetylcholine is known to be involved with erectile function and memory. While White Kwao Krua has business potentials for females, Red Kwao Krua seems to have such commercial promises for males that it has been called the "Rejuvenating herb".

Another study shows that Butea Superba works primarily by increasing the relaxation capacity of the corpus cavernous smooth muscles (which are the two chambers in the penis) via cAMP phosphodiesterase (PDE5) inhibition and it also is believed to act on the brain by actually triggering the improvement of the emotional sexual response. PDE 5 is often called the "erection killing" enzyme in your body. PDE 5 sole job is to deflate erections. Men who have trouble achieving and maintaining an erection most often it is because of the PDE 5 enzyme has not been neutralized. The longer the PDE 5 enzyme can be neutralized the longer erections last, the easier it is for erections to occur and the more the chambers of the penis can expand thereby increasing the size, quality, fullness, firmness and frequency of erections. No other natural compound can do this.

The Butea superba Extract or Red Kwao Krua Extract used in dietary supplements is derived from the tuberous roots of the plant Butea superba.
