I had started using a juice made from the fruit mangosteen for other health problems. It had helped me so much that I began doing research on the the Xanthones that are found in the rind of the fruit. There is a lot of papers written on cancer. Some of the xanthones were compared to different chemo drugs and out performed some of them in test. You can do your own research at www.pubmed.com by typeing in xanthones. You can research all most anything at this site.
Have a blessed day.
