Anticancer effect
On the one hand, quercetin can effectively inhibit the production of free radicals. Its flavonoid components such as quercetin can significantly reduce the incidence of gastric cancer, directly inhibit the growth of cancer cells or may act on the cell transduction pathway of cancer cell proliferation.
