“Autointoxication” is a belief that intestinal waste products poison the body and contribute to many, if not all (claimed by some) diseases. During the 19th century this was a very popular theory and led to various forms of colonic irrigation. However, scientific evidence shortly after the turn of the century demonstrated that colonic irrigation was not only useless, but potentially dangerous. The modern comeback is based on the same old claims. Since 1997, the FDA has issued at least seven warning letters related to colon therapy. After all, the gastrointestinal system was originally designed to work from the top down–not the other way around!
PositiveTip: Eating a healthy, fiber-rich diet and drinking plenty of water is the best way to keep you colon healthy.
