In reality, there is a great deal of similarity between the concept of “autointoxication” and certain religions. In the case of “autointoxication,” the body of the person with a disease is viewed as “unclean,” contaminated by itself, and, of course, in dire need of cleansing. Does anyone see the parallels to Christian doctrine? Consider: According to Christian religions, people are inherently “unclean” because of original sin that, no matter what they do themselves, they cannot remove. (Only God can.) Now consider the beliefs that drive colon cleansing, in which adherents believe that they are inherently unclean, full of “putrefaction,” and being “poisoned” from within through the absorption of “toxins” (whose exact identities are conveniently rarely, if ever, specified). They believe that they need something to “cleanse” that uncleanliness before they can be well. Compare that to not just Christianity, but to a number of religions in which adherents must “cleanse” themselves of evil and putrefaction by various purifying acts and rituals. This should not be surprising, as the beliefs that drive people to cleanse their colons by various means are not based in science, but rather seem to be more religious or quasireligious in nature.
One thing’s for sure. Colon cleansing is a dubious and almost always useless procedure that shows no signs of going away. There is a thriving market offering an amazing number of products that claim to be able to rid you of all that nasty fecal buildup that doesn’t exist. It may be the most obvious retort in the world for such woo, but the very nature of these sorts of products makes it difficult to avoid–nay, it demands that I not avoid–saying that colon cleansing is a load of…well, you know.
