Quercetin is a potent antioxidant and has anti-inflammatory
activity, protecting cellular structures and blood vessels from the
damaging effects of free radicals. It improves blood vessel
strength. Quercetin inhibits the activity of
catechol-O-methyltransferase that breaks down the neurotransmitter
norepinephrine. This effect may lead to elevated levels of
norepinephrine and an increase in energy expenditure and fat
It also means quercetin acts as an antihistamine leading to 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.
Quercetin is pentahydroxyflavone achieved from rutin which is
hydrolyzed by dilute sulphuric acid.
This product has functions of eliminating phlegm, relieving cough
and a certain degree of relieving
asthma. Meanwhile, it can reduce blood pressure, strengthen
capillaries, decrease capillary fragility,
reduce blood lipid, dilate coronary artery, increase blood flow of
coronary artery etc.
It is used for the treatment of chronic bronchitis, and the
adjuvant therapy of coronary heart disease and hypertension.
It has good expectorant, cough effect, and some asthma, for the
treatment of chronic bronchitis.
It can lower blood pressure, fragility, blood fat, expanse coronary
artery, and increase capillary resistance coronary blood
flow, and other effects on the coronary heart disease and
hypertension role of adjuvant therapy.
It can beanti-tumor and anti-platelet aggregation.
It can inhibit platelet aggregatireduce capillaryon and 5 -
hydroxytryptamine (5-HT) release
One of the many health benefits of quercetin is that it acts as a
potent antioxidant combating the destructive "free radical"
molecules that play a part in many diseases.
Quercetin also has healthful anti-inflammatory and anti-allergy
effects. It inhibits the production and release of histamine and
other allergic/inflammatory mediators, making it of value for
allergies, particularly allergies to pollen. It may also be helpful
for hayfever, hives, sinusitis, asthma, and inflammation disorders.
Quercetin, along with other flavonoids, can also improve the health
of capillaries. In addition, quercetin, along with other
flavonoids, can improve the health of connective tissues.
Therefore, the many health benefits of quercetin include
alleviating bruising, edema, varicose veins, and fragile
In test tube and animal studies quercetin has shown to have
anti-cancer effects. In fact, flavonoids from fruits and
vegetables have long been thought to be very important substances
to possibly help prevent cancer.
One study suggests that quercetin is helpful for prostate health.
More specifically, in a double-blind study quercetin was effective
in non-bacterial chronic prostatitis (inflammation of the prostate
Test tube, animal, and some population-based studies suggest that
quercetin, resveratrol, and catechins -- all flavonoids -- reduce
the risk of atherosclerosis. Atherosclerosis is a narrowing of the
arteries from a buildup of fatty deposits called plaque that can
lead to heart attack or stroke. However, studies in people are
needed to confirm these findings.
Quercetin has also been shown to be a strong inhibitor of human
lens aldose reductase - an enzyme that plays a part in the
formation of diabetic cataract, neuropathy, and retinopathy.
Lastly, quercetin enhances the action of vitamin C, another
