Eva Lou - I won't argue one way or the other on this, because I don't know much about it (cleanses), but you have to check out this website for Colonix. BE WARNED - the pictures are absolutely disgusting, but its STUNNING to see what's built up in colons of some poeple. I can certainly understand why these people were constipated.
Again, if you have a squeamish stomach, you might not want to see this. I just couldn't believe it:
