Well, I’m more confused now than before I asked the question :-/
On the one hand, I’m challenged to explain my thinking why I dare to suspect a scam. On the other hand, it’s an outright scam. Is the answer somewhere in the middle, as compromisers would say? Or is it one or the other?
Now, I know a thing or three about biology and medicine, and so I know there’s no build-up of toxins or residue on the lining of the colon over years (too bad the same can’t be said of major blood vessels). Any foreign matter inside the colon will get expelled (if foreign matter collects anywhere, it would be in the appendix).
I’d be willing to try it to appease this girl I know, but not if it’s actually dangerous. And who knows, there might be some ancillary health benefits from the herbs…
