Quercetin is a potent antioxidant and has antiinflammatory activity, 

protecting cellular structures and blood vessels from the damaging 

effects of free radicals. It improves blood vessel strength. Quercetin 

inhibits the activity of catecholmethyltransferase that breaks down the 

neurotransmitter norepinephrine. This effect may lead to elevate the 

levels of norepinephrine and an increase in energy expenditure and 

fat oxidation. It also means quercetin acts as an antihistamine leading to 

the relief of allergies and asthma. As an antioxidant, it reduces LDL 

cholesterol and offers protection from heart disease. Quercetin blocks 

an enzyme that leads to accumulation of sorbitol, which has been linked 

to nerve, eye, and kidney damage in diabetics.

curing asthma for the treatment of chronic bronchitis.

and increase capillary resistance coronary blood flow, and other effects on 

the coronary heart disease and hypertension role of adjuvant therapy.

3.It shows functions including anti-tumor and anti-platelet aggregation.
