Detail Information of Quercetin

Quercetin, a flavonol, is a plant-derived flavonoid found in fruits, vegetables, leaves and grains.

It also may be used as an ingredient in supplements, beverages or foods.

In laboratory studies of cells in vitro,

quercetin produces changes that are also produced by compounds that cause cancer (carcinogens),

but these studies do not report increased cancer in animals or humans.

Several laboratory studies show quercetin may have anti-inflammatory properties,

and it is being investigated for a wide range of potential health benefits.

Quercetin has been reported to be of use in alleviating symptoms of pollinosis.

An enzymatically modified derivative was found to alleviate ocular but not nasal symptoms of pollinosis.
