Quercetin Dihydrate is a type of plant-based chemical, or phytochemical, known as a flavonoid (see also Phytochemicals). Good sources include apples, onions, teas, red wines, and many other foods. Quercetin Dihydrate is also available as a dietary supplement.
Quercetin Dihydrate appears to have anti-inflammatory and antioxidant properties. It has been promoted as being effective against a wide variety of diseases, including cancer. While some early lab results appear promising, as of yet there is no reliable clinical evidence that Quercetin Dihydrate can prevent or treat cancer in humans.

Function
1. Quercetin dihydrate eliminates phlegm and relieves cough
2. Quercetin dihydrate lowers lipid and blood pressure
3. Quercetin dihydrate increases blood capillary immunity
4. Quercetin dihydrate is useful in anti-tumour
5. Quercetin dihydrate can prevent platelet aggregation, etc.
Application
1.Pharmacokinetics
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.
2.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.
