The pharmacutical companies don't want you to get better, if you did they would not be able to sell you more drugs. I think any drug that kills people or with long term use destroys their kidneys and liver is bad regardless of the percentages.
There are numerous doctors on board with Xango and they have been doing their own testing and guess what ! they have proof of it's effectivness. I will try to find the video clip from Dr. Walters who did ultra sound on a large artery showing the fat refuse from eating a greasy burger fries and a pop. He then repeated the experiment after the subject ate the burger, fries and pop this time the subject took 2 oz of Mangosteen juice. The difference was staggering. There was no fat clinging to the arterial walls post Mangosteen.
