    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

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

    to nerve, eye, and kidney damage in diabetics.
