Dr. Axe (2017) states that Quercetin plays a significant role in fighting free radical damage. Dr. Axe also stated that the Department of Pathology and Diagnostic at the University of Verona Italy found that Quercetin has antiviral, antimicrobial, anti-inflammatory and anti-allergic properties with the potential to be positively expressed in cells of humans and animals. Quercetin shows strong effects on immunity and inflammation caused by leukocytes (Dr. Axe, 2017).

According to Axe, anti-inflammatory foods that contain Quercetin can help to manage inflammatory health problems such as allergies. It is because these high antioxidant foods have the ability to scavenge free radicals. Quercetin helps to slow the aging progress because it lessens the effect of oxidative stress on the body (Axe, 2017).
