Action:

Flavonoid with anticancer activity. Mitochondrial ATPase and phosphodiesterase inhibitor. Inhibits PI3-kinase activity and slightly inhibits PIP Kinase activity. Has antiproliferative effects on cancer cell lines; reduces cancer cell growth via type II estrogen receptors; has been reported to arrest human leukemic T cells in late G1phase of the cell cycle.

Pharmacologly:

Quercetin offers a variety of potential therapeutic uses, primarily in the prevention and treatment of the following conditions:
Allergies, asthma, and hives: Quercetin may inhibit histamine release from basophils (a type of white blood cell) and mast cells (large cells in connective tissue).

Canker sores: Quercetin may reduce the frequency of mouth sores and produce mild symptomatic relief.

Heart disease: Individuals with very low intakes of flavonoids are at higher risk for heart disease.

Infection: Quercetin may control the spread of certain viruses within the body.

Rheumatoid arthritis: Quercetin may help reduce tissue destruction.

Quercetin may also be beneficial in the treatment of dysentery (an intestinal infection causing severe diarrhea), gout (a disease where crystals of uric acid, a component of urine, are deposited in the joints and cause swelling), and psoriasis (a chronic skin disease).
