This may be a point of contention, but I now believe that colon cleansing is a scam. The research that stems from some of the websites I've visited are pure nonsense.

For instance:
claim - toxins are absorbed into the body by feces that accumulate on the intestinal walls.
evidence - you'll feel better after a cleanse. testimonial, testimonial, testimonial.

What kind of marketing is this? For stupid people? It's got all the buzz words to make you think you're buying a great product.

Here's an idea..

I've got a product that will make you smarter, live better, eat healthier, and be a pleasant, more productive person. I'm telling you IT WORKS. By taking a two to three doses per day (it comes in easy to use bottles), you'll feel better. It will improve your mood. Its a natural diuretic and will cleanse your bladder from the toxins that accumulate on the bladder wall. The liquid is also thick, so it will coat and help alleviate sore throats. There's a nitrogen capsule inside works two fold: it assures you of it's freshness and helps to rejuvenate your cell walls and cell membrane in your stomach when you digest it. It's made from the best stuff on earth and is all natural. That product my friend is none other than Guinness draught beer!
