I'm a breast cancer survivor (3 years) and I'm always on the lookout for ways to boost my immune system to keep me healthy. I also have a Ph.D. and am very skeptical of most alternative treatments. However, I've read over a dozen academic medical research articles about how the mangosteen fights cancer in 3 ways:
First, it's a powerful antioxidant to prevent cancer cells from forming.
Second, it works as an antiproliferant to stop cancer from spreading
third, it works as a apoptic agent to actually kill cancer cells.
This research is extremely exciting. Some of the big pharmaceutical companies are recruiting these scientists away from medical schools in order to develop drugs from the mangosteen, but of course, those treatments are years away. I'm drinking the XanGo juice daily, just as preventive insurance. It tastes delicious. The key is to drink mangosteen juice that has the pericarp (rind) mixed into it because that's where all the nutrients are. XanGo is the only company that has the patent on using the pericarp in its juice, so it's by far the best on the market.
