Japanese Sophora Flower Bud Extract
Also known as: Sophora japonica, Japanese sophora, Pagoda tree, Sophora flower bud extract, Styphnolobium japonicum
Overview
The dried flower and flower bud of *Styphnolobium japonicum*, commonly referred to as *Sophora japonica*, are widely utilized in traditional herbal medicine and as dietary supplements due to their potential health benefits. This extract is particularly abundant in flavonoids such as rutin and quercetin, which are associated with anti-inflammatory, anti-oxidative, and potential anti-cancer properties. It also contains various active compounds, including saponins, polyphenols, volatile oils, and phenolic acids, contributing to its myriad of medicinal applications. Despite a wealth of documented benefits, the majority originate from in vitro and animal research, emphasizing the need for further human clinical trials to substantiate its efficacy and safety. Available in forms like powders and capsules, *Sophora japonica* is designed to enhance the absorption of its bioactive flavonoids.
Benefits
Research indicates that *Sophora japonica* flower bud extract may offer various health benefits, primarily due to its strong anti-oxidative and anti-inflammatory actions. It has demonstrated the ability to inhibit the enzyme xanthine oxidase, potentially aiding in the reduction of uric acid levels and treatment of conditions such as gout. Furthermore, findings suggest its effectiveness in managing metabolic syndrome and highlight its anti-cancer potential, attributed to its rich flavonoid content. However, the supporting evidence is derived mainly from animal and laboratory studies, underscoring the necessity for additional human trials. Generally, adults find it safe, although pregnant and breastfeeding women are advised to consult healthcare professionals before use.
How it works
*Sophora japonica* flower bud extract employs its active compounds to engage biological pathways involved in oxidative stress and inflammation. Its key mechanism involves inhibiting oxidative enzymes, leading to reduced oxidative damage and inflammation. A notable pathway includes its action on xanthine oxidase, an enzyme integral to uric acid production, thus assisting with conditions like hyperuricemia.
Side effects
The safety profile of *Sophora japonica* flower bud extract is generally considered favorable, with no well-documented common or severe side effects observed in current literature. Clinical and animal studies report no significant adverse events related to its consumption. However, individuals taking certain medications, especially those affected by flavonoids like rutin and quercetin, should be cautious. Furthermore, due to limited safety data, it is particularly important for pregnant and breastfeeding women to consult healthcare providers regarding the use of this extract, as available research does not comprehensively cover its safety for these populations.
Dosage
Precise dosage recommendations for *Sophora japonica* flower bud extract in humans are not well established owing to the absence of clear guidelines. Effective dosages observed in animal studies range from 200 to 600 mg/kg; however, this does not directly translate to human dosing recommendations, complicating the determination of optimal dosages. There are currently no recognized maximum safe doses. The extract's bioavailability may vary based on its formulation—whether in capsules or powders—and thus, considering extraction methods and potential nutrient interactions is crucial for determining effective dosages.
