QUERCETIN is a flavonol, a type of flavonoid compound found naturally in apples, onions, citrus, sage, tea, red grapes and many other fruits and vegetables. Flavonoids are plant pigments that exhibit potent antioxidant and anti-inflammatory properties.
Quercetin supplements are frequently used to provide anti-histamine, anti-inflammatory and anti-allergy benefits.
In vitro, quercetin has been shown to help stabilize mast cells, a type of immune cell involved in histamine release and the inflammation response.
