Fortunately, a number of studies have already revealed that eating fruit and vegetables helps to prevent cancer, and that this is likely due to the presence of proanthocyanidins.
A team of scientists from the US and China have discovered that grape-seed extract kills laboratory leukemia cells by making them commit suicide, thus showing the potential value of natural compounds in the treatment of cancer.
The study was the work of lead author, Dr Xianglin Shi, professor in the Graduate Center for Toxicology at the University of Kentucky and colleagues and is published online in the 1 January 2009 issue of Clinical Cancer Research, a journal of the American Association for Cancer Research.
Shi and colleagues used a commercially available grape seed extract and exposed leukemia cells to various concentrations of the extract for 12 and 24 hours, and also looked at what happened when leukemia cells were exposed to 50 µg/mL of the extract over various time intervals.
The results showed that exposure to grape seed extract resulted in dose and time-dependent increase in cancer cell apoptosis. They also discovered that the extract did not affect normal cells but they weren't able to determine why.
Studies on grape seed extract have also suggested that it reduces breast tumors in rats and skin tumors in mice, and is active in a number of laboratory human cancer cell lines (such as skin, breast, colon, lung, stomach and prostate cancer cells), but until now nobody has investigated its effect on blood cancers.
No one ever said something about the power of the seeds when it comes to treating cancer and maybe it is because pharmaceutical companies will not make money out of them.
But the positive thing is that the traditional medicine is getting better and better and the traditional medicine is not going to let more people to die from cancer just for the money.
