quercetin Pharmacology
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).
Of the 80-plus supplements included in the Wellness Guide to Dietary Supplements, quercetin consistently ranks as one of the most visited pages. That surprised us, so we decided to see why people are so interested. For many years now this compound—found in apples, tea, red wine, and other foods—has been studied for possible health benefits. Research has been accumulating, and though it is still in its early stages, many people are jumping on the quercetin bandwagon.
Quercetin is an important member of a large group of plant compounds called flavonoids, once thought to be vitamins. Here are some of its potential benefits:
• This plant pigment is an antioxidant, and thus may help fight cell-damaging free radicals. (But like other antioxidants, it may also act as a pro-oxidant—that is, have the opposite effects and actually become a free radical—under some circumstances.)
Lab studies suggest that it may have anti-cancer effects, help prevent heart disease by reducing the oxidation of LDL ("bad") cholesterol, and act as an antihistamine.
• Specifically, it may help treat or even prevent prostate cancer by blocking male hormones that encourage the growth of prostate cancer cells, according to preliminary laboratory research at the Mayo Clinic. In another study, men with an inflamed prostate (prostatitis) reported reduced urinary symptoms when they took quercetin.
• Population studies have found that people with high intakes of foods containing quercetin and other flavonoids tend to have lower rates of heart disease and lung cancer.
• Several studies have linked a high intake of apples (rich in quercetin and other flavonoids) with improved lung function and a lower risk of certain respiratory diseases, such as asthma, bronchitis, and emphysema.
