I just want to say I think everyone should be researching the Xango product. I've been reading lots of information on this and how wonderful xanthones are for you that come from the mangosteen fruit. It's suppose to help with many different things i.e. how amounts of antioxidants, digestion problems, anti-inflammatory, immune modulator are just a few to name. There are several high profile docs that use this for themselves and their patients. Including world-renowned Dr. Amod Tootla, M.D. and scientist, he's the doc the introduced laproscopic colon surgery and robotic surgery to the U.S. There are many studies on mangosteen in laboratories before Xango even came along. If you do research, <u><i>search for mangosteen or xanthone(s)</i></u>. I have absolutely nothing to do w/ this company, I've just really been researching it to use on my daughter w/ CF. Please research this and let me know what you think.
