Quercetin has been shown to combat inflammation and acts as a natural antihistamine. Several studies have highlighted quercetin’s ability to prevent and treat both the common cold and influenza.

Other, less-known benefits and uses for quercetin include the prevention and/or treatment of high blood pressure, cardiovascular disease, metabolic syndrome, certain cancers, gout, arthritis and mood disorders.

A review of quercetin’s effect on metabolic syndrome found it significantly reduced fasting plasma glucose when taken for at least eight weeks at a dosage of 500 milligrams per day or more.

Other recent research found quercetin has a beneficial impact on non-alcoholic fatty liver disease by ameliorating inflammation, oxidative stress and lipid metabolism.

Quercetin also has the ability to trigger tumour regression by interacting with your DNA and activating the mitochondrial pathway of apoptosis (the programmed cell death of damaged cells).
