The cancer-fighting properties of Quercetin.

Quercetin belongs to a group of plant-based polyphenols known as flavonoids, which are responsible for many of the colors, flavors, and aromas of fruits, vegetables, and herbs. It is a potent antioxidant and has been found to scavenge free radicals, reduce inflammation, and inhibit the growth of cancer cells.

Quercetin has also been found to modulate multiple oncolytic pathways associated with cancer, including those involving the cell cycle, apoptosis, autophagy, angiogenesis, and metastasis.

Quercetin inhibits the uptake of lactic acid into tumor cells. It does this by suppressing the glycolytic enzymes hexokinase and phosphofructokinase which are involved in the uptake of lactic acid.
