The theory of colon hydrotherapy is more historical and intuitive than scientific as there have not been any studies to validate the effectiveness of this modality. Many cultures believe that clean colon can improve the health of an individual. This started thousands of years ago with the simple enema and has evolved into the present day colonic. An FDA approved device is used to gently flush the colon with warm water. Many people report that they feel better after a colonic. A growing number of health care practitioners believe that a sluggish bowel allows the body to reabsorb toxins from the colon. Anything ca be done to assist the body in ridding itself of toxins should have some value.
