1.Quercetin Dihydrate is used for treating conditions of the heart and blood vessels including "hardening of the arteries" (atherosclerosis), high cholesterol, heart disease and circulation problems.
2.Quercetin Dihydrate is also used for diabetes, cataracts, hay fever, peptic ulcer, schizophrenia, inflammation, asthma, gout, viral infections, chronic fatigue syndrome(CFS), preventing cancer and for treating chronic infections of the prostate.
3.Quercetin Dihydrate is also used to increase endurance and improve athletic performance.
Quercetin is a potent antioxadant and has anti-inflammatory activity, protecting cellular structures and blood vessels from the damading effects of free radicale. It improves blood vessel strength. Quercetin inhibits the activity of catechol-O-methyltransferase that breaks down the neurotransmitter norepinephrine. This effect may lead to elevate thelevels 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 diaease.
Application of Quercetin Dihydrate:
The bioavailability of quercetin in humans is low and highly variable (0-50%), and it is rapidly cleared with an elimination half-life of 1-2 hours after ingesting quercetin foods or supplements. Following dietary ingestion, quercetin undergoes rapid and extensive metabolism that makes the biological effects presumed from in vitrostudies unlikely to apply in vivo.
In vitro pharmacology
Quercetin has been reported to inhibit the oxidation of other molecules and hence is classified as an antioxidant.Quercetin contains a polyphenolic chemical substructure that stops oxidation by acting as a scavenger of free radicals that are responsible for oxidative chain reactions.
