The idea was that the intestines were a sewage fixed order and that constipation, although never specifically defined, resulted in a cesspool within the constitution where entree wastes would putrefy, become toxic, and get reabsorbed through the intestines. Some scientists also claimed that constipation caused fecal matter to harden http://www.cleansercolon.com/cleansers/bowtrol-colon-cleanse-review onto the intestinal walls for months or years, blocking the absorption of nutrients (yet somehow not blocking toxins).

While colon cleaning can make some people feel better, it doesn't cure any disease; it's no more effective at relieving discomfort than an enema; and it is tantamount to throwing money down the proverbial toilet.
