In addition, quercetin effects on allergy, asthma, and atopic disease. In murine models of allergic airway inflammation and asthma, quercetin had pronounced anti-inflammatory effects and inhibited asthmatic reactions. Furthermore, this substance has a variety of anticancer mechanisms, including antioxidant, anti-proliferative, pro-apoptotic, and cell signaling effects, and growth factor suppression, as well as potential synergism with some chemotherapeutic agents. Quercetin effects on diabetes by its inhibitory function of lens aldose reductase-the enzyme that catalyzes the conversion of glucose to sorbitol-that is especially important in the eye and plays an essential role in the formation of diabetic cataracts. Quercetin supplementation attenuates the development of cardiac hypertrophy induced by overloaded pressure. Finally, quercetin has gastro protective and oral mucosa effect and had benefits on immunity, infections, inflammation, injury, pain, prostatitis, arthritis, metabolic syndrome, obesity, mood disorders and sleep.Conclusion: Due to the important role of quercetin in prevention and treatment of diseases, a daily dietary fruit, vegetables, seeds and nuts to supply quercetin is recommended.
