I think Marcel has a very valid point here... While I am by no means a GI expert, I do have a fairly strong medical background and therefore would prefer to see some blind scientific clinical studies done on treatments like this before I use them. Of course this is just my individual opinion. It's important to remember that Colonix and other similar product are neither approved nor regulated by the FDA, and since they are listed as 'herbal remedies' it is my understanding that they can basically claim whatever they choose so long as they indicate it's herbal and not FDA approved or regulated. Again, I'm not saying you should or shouldn't use this stuff, but for me, as long as my pooper is workin' like it should and I feel ok, then I'm not gonna mess with it haha.
