Xanthone the anti-oxidant

The problem is the lack of research; xanthones, while medically promising, have not been studied under clinical conditions in the actual treatment of human disease. Also, marketers have hyped the "fact" that there are supposed to be 40 xanthones in the mangosteen. The trouble with this is that commercial websites are the only source for this "research"; reputable scientific and nutrition journals are cautious about making such claims for mangosteen precisely because there haven't been enough studies on its properties.

Yes I agree, according to the last reports I have seen their is about 43 xanthons found in this amazing fruit. Each one doing something different for the body.
