“Cancer cells are fast-growing cells,” Agarwal says. …When conditions exist in which they can’t grow, they die.”
Grape seed extract creates these conditions that are unfavorable to growth. Specifically, the paper shows that grape seed extract both damages cancer cells’ DNA (via increased reactive oxygen species) and stops the pathways that allow repair (as seen by decreased levels of the DNA repair molecules Brca1 and Rad51 and DNA repair foci).
Safe for normal cells though.
Hmmm. Is it time to start incorporating some grape seed extract in our meals to ward off head and neck tumors?
