Quercetin

Quercetin is a plant-derived flavonoid sometimes used as a supplement to support immune function during upper respiratory infections. It has antioxidant and anti-inflammatory properties and may help stabilize mast cells, potentially reducing inflammation and histamine release. Quercetin has also shown antiviral activity in laboratory studies, though clinical evidence in URIs is limited. It is generally well tolerated, but its benefits should be considered adjunctive rather than a replacement for standard symptomatic treatments.
