Function and Usage:
Resveratrol interferes with all three stages of carcinogenesis initiation, promotion and progression. Experiments in cell cultures of varied types and isolated subcellular systems in vitro imply many mechanisms in the pharmacological activity of resveratrol. In some lineages of cancer cell culture, resveratrol has been shown to induce apoptosis, which means it kills cells and may kill cancer cells.Resveratrol has been shown to induce Fas/Fas ligand mediated. Resveratrol also possesses antioxidant and anti-angiogenic properties.
