Action and Uses |
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. |
