Quercetin
Quercetin is a naturally occurring bioflavonoid found in high concentrations in red wine, onions and green tea. Quercetin possesses powerful antioxidant properties and like other bioflavonoids, has the ability to stabilize cell membranes. These qualities contribute to Quercetin's ability to support healthy histamine levels and balanced immune function. Quercetin is a flavonoid and more specifically a flavonol. It is the aglycone form of a number of other flavonoid glycosides, such as rutin and quercitrin found in citrus fruit. Quercetin is found to be the most active of the flavonoids in studies, and many medicinal plants owe much of their activity to their high quercetin content. Quercetin has demonstrated significant anti-inflammatory activity because of direct inhibition of several initial processes of inflammation.
