AOR Quercetin - Quercetin is the flavone aglycone (non-sugar-bound) form of the polyphenolic flavonoid rutin. It is the major bioflavonoid in the human diet. Quercetin's main application is for those with allergy symptoms (such as itchy eyes, itchy throat, sneezing and nasal congestion), quercetin also promotes cardiovascular health due to its antioxidant and anti-inflammatory effects. It reduces the oxidation of low density lipoproteins (LDL), promotes healthy blood pressure and blood clotting, enhances nitric oxide (NO) production, and reduces the risk of metabolic syndrome. Quercetin can provide relief from headaches and other types of pain, as it inhibits the production of inflammatory signaling molecules by a mechanism similar to that of aspirin. Quercetin also inhibits the release of histamine from certain immune cells, hence why it is widely used by those who suffer from constant allergies  (such as dust) and seasonal allergies (such as hay fever).
