Uses

Quercetin (CAS NO.117-39-5) has demonstrated significant anti-inflammatory activity by inhibiting both manufacture and release of histamine and other allergic/inflammatory mediators.In addition, it exerts potent antioxidant activity and vitamin C-sparing action. It has also been claimed that quercetin reduces blood pressure in hypertensive subjects. An in-vitro study on fat cells suggested that quercetin and resveratrol may have a synergistic anti-obesity effect.

Specification

Drug interactions of Quercetin (CAS NO.117-39-5): It is contraindicated with some antibiotics; it may interact with fluoroquinolones (a type of medicinal antibiotic), as quercetin competitively binds to bacterial DNA gyrase. It is also a potent inhibitor of CYP3A4 and CYP2C9, which are enzymes that break down most drugs in the body.
