Descriptions:

Quercetin is a flavanoid obtained by extraction from the vegetable raw material, scphora japonica. Rutin is practically insoluble in water while soluble in methanol and ethanol, is a supplement used to treat poor blood circulation, hemorrhoids, and Meniere's disease. Quercetin is a flavonoid widely distributed in nature. The name has been used since 1857, and is derived from quercetum (oak forest), after Quercus. It is a naturally occurring polar auxin transport inhibitor.

Quercetin itself (aglycone quercetin), as opposed to quercetin glycosides, is not a normal dietary component. In a bioavailability study in rats, radiolabelled quercetin-4'-glucoside was converted to phenolic acids as it passed through the gastrointestinal tract, producing compounds not monitored in previous animal studies of aglycone quercetin. All but 4% was recovered within 72 hours (69% in urine), indicating low retention and high excretion, a characteristic of ingested polyphenols. Quercetin may also induce insulin secretion by activation of L-type calcium channels in the pancreatic β-cells. Quercetin has not been confirmed scientifically as a specific therapeutic for any condition nor approved by any regulatory agency. The U.S. Food and Drug Administration has not approved any health claims for quercetin.
It can enhance the absorption of Vitamin C, helps relieve pain, bumps and bruises, has an antibacterial effect, promotes circulation, stimulates bile production, helps lower blood cholesterol, and prevents cataracts.
