A study published this week in the medical journal Carcinogenesis shows that grape seed extract kills head and neck squamous cell carcinoma cells, while leaving healthy cells unharmed. The grape seed extract (also known as proanthocyanidins and/or flavinoids)has been demonstrated to damage cancer cell DNA (by way of increasing reactive oxygen), as well as inhibiting the cancer cell’s ability to repair the damage. The best part is that the grape seed extract is not harmful to normal cells. This is probably due to the fact that cancer cells are known to have a lot of deficient metabolic pathways that can be vulnerable to attack. Normal cells do not have most of these vulnerabilities.
Another study that was published in the January 1, 2009 issue of Clinical Cancer Research by researchers from the University of Kentucky found that an extract from grape seeds caused in vitro leukemia cells to commit suicide. continue reading…
