From Kook Science

This category is for articles relating to the theory of Autointoxication, or infection as a consequence of decomposition of matter in the bowels (particularly the intestines and colon), and curatives or devices proposed to prevent and cure maladies attributed to this condition. As you may expect, that means enemas, sanitary liquids poured into the rectum, and varying levels of quackery. Peruse and sample at your own discretion.
