Thai Red Kwao krua (Male enhancer) – Butea superba 25x extract
From the same organic farm in Thailand which supplies our Blue Lotus
Supplied in a 50g resealable bags.
This tuber has traditionally been used for the enhancement of male vitality and as an aphrodisiac in Thailand, and appears to be a source of androgenic compounds.
When studies investigated the androgenic effects, there appears to be the classical signs of direct androgenic activation (particularly, an increase in liver enzymes in some studies and growth of male sex organs; a decrease in testosterone levels in serum has been noted possibly due to negative feedback) but unlike its sister herb (Pueraria Mirifica) the bioactives mediating these androgenic effects are not currently known nor are their potencies relative to testosterone known.
Low doses of Butea Superba appear to be safe for human consumption, based on limited evidence, although higher doses have been connected to mutagenicity in mice (300-1000mg/kg, a human equivalent of 48mg/kg or above) and as such are not advisable.
Antioxidant
Red Kwao Krua (Butea superba Roxb.) is a protected medicinal plant of Thailand. Red substances are released when the tuberous roots of Red Kwao Krua (RKK) are wounded. This study aimed to find the amount and capacity of an anthocyanin in the tuberous roots of RKK. Anthocyanin was determined from the extracted solution of the tuberous roots of RKK with two mobile phases (HCl: formic acid: H2O, 25: 24: 51 and 7: 51: 42 v/v) using TLC technique [1] and the absorbent wavelength of visible light. The amount of anthocyanin was determined by pH differential technique [2]. The antioxidant capacity was determined by using DPPH [3], ABTS [4] and the inhibition of LDL oxidation techniques [5] in comparison with standard trolox. The Rf values of extracted solution were 0.12 and 0.34 and they absorbed wavelength at the peak of 519nm also their color changed from red to brown when the pH had been changed from 1 to 14 which are characteristics of anthocyanin [6,7,8]. The diameter of cortex of tuberous root of RKK was correlated with the amount of anthocyanin. Tuberous roots of RKK contained anthocyanin between 69–144µg/g fresh weight. The RKK crude extract had approximately the same IC 50 as trolox.
