Description:

     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.
