I just want to put this out there:
Pretty much anything "cured" by a colonic is something that's a diet or lack of exercise problem. There is literally no empirical medical evidence of any postiive benefits form them, other than psychosomatic ones. In fact, they're potentially dangerous, as people can rupture their bowels doing them.
I'll look the other way if you're promoting diet pills, because the worst of them are just some chalk and a little speed... no harm unless someone's got a predisposition to speed-psychosis. But colonics are actually dangerous.
Taking money from idiots is one thing. Endangering people is entirely another.
On a related note, I think I mentioned it before, but colonics were the cureall prescribed by John Kellog, the guy what invented Corn Flakes.
There's a book (also a good movie with John Cusack) called The Road to Wellville, which is semi-fiction-semi-fact.
Seriously, go read or watch it.
