Butea
Also known as: Red Kwao Krua, Kwao Krua Daeng, *Butea superba*
Overview
*Butea superba* is a plant native to Thailand, recognized for its traditional use as an herbal supplement to enhance male sexual function, particularly in addressing erectile dysfunction (ED). The plant contains flavonoids and flavonoid glycosides, which may contribute to its purported benefits. While there are some clinical trials investigating its effects, the overall maturity of research remains moderate, characterized by small study sizes and a lack of extensive validation. Current findings suggest it may improve erectile function in males, although the body of evidence is not exhaustive, with more rigorous studies needed to establish clear clinical guidelines.
Benefits
*Butea superba* has primarily been studied for its potential to improve erectile function, with a clinical trial indicating a significant improvement in 82.4% of participants as measured by the International Index of Erectile Function (IIEF-5) questionnaire. Secondary benefits may include a possible increase in sexual desire and overall satisfaction, though evidence for these effects is limited. These findings are mainly relevant to Thai males experiencing ED, with moderate effect sizes noted. Benefits were typically observed over a period of three months, emphasizing the importance of a consistent regimen for optimal results.
How it works
The precise mechanism by which *Butea superba* exerts its effects is not fully elucidated. It is believed that the flavonoids and other bioactive compounds present in the plant may enhance blood circulation or modulate hormonal activities that influence sexual function. However, there remains a lack of detailed research into specific biological pathways or target mechanisms within the body.
Side effects
Overall, *Butea superba* is generally considered safe in the short term, with no significant toxicity reported in clinical trials. Common side effects include mild gastrointestinal upset, although comprehensive data on adverse reactions are insufficient. Uncommon or rare side effects have not been documented due to limited data. Potential drug interactions may occur with medications affecting blood flow or hormonal levels, although these interactions have not been extensively studied. Caution is advised for individuals with cardiovascular complications or those using erectile dysfunction medications. Pregnant or breastfeeding women are advised to avoid *Butea superba*, pending further safety data.
Dosage
Specific dosage guidelines for *Butea superba* are not firmly established, as dosages are not standardized and primarily involve crude preparations. An optimal dosage range has yet to be determined, and users should consider the form used—typically raw tubers—and individual absorption characteristics. There is currently no established upper limit for safe doses, and due to variability in preparation, recommendations around the timing of administration are not specified. Users are encouraged to approach this supplement cautiously, particularly given the lack of definitive dosing studies.
