Quercetin is a flavonoid found in many plants and foods, such as apples, berries, and onions.
It is known for its antioxidant and anti-inflammatory properties, which it exerts by neutralizing free radicals and inhibiting inflammatory mediators.
These activities make quercetin an interesting molecule for research into its potential application in the prevention and treatment of diseases associated with oxidative stress and chronic inflammation, such as cardiovascular diseases and certain types of cancer.
Moreover, preclinical studies suggest that quercetin may have antiviral and anti-allergic effects by modulating specific signaling pathways.
