Description:
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.
