Leukaemia cells have been shown to die when treated with grapeseed, and whole-grape extracts. In one study, a commercially available extract caused 75% of the blood cancer cells to be destroyed  – in a process of natural self-destruction of cancer cells called apoptosis. In addition, all healthy cells remained unharmed. New treatments are believed to result from such studies, including several nutraceuticals. It is believed that the antioxidants and Resveratrol in grapeseed (as well as in whole-grape extracts) create the observed results.

 ”These results could have implications for the incorporation of agents such as grape seed extract into prevention or treatment of haematological (blood) malignancies and possibly other cancers,” said Professor Xianglin Shi, from the University of Kentucky in Philadelphia.
