The colon exists to carry away waste material that is unusable by the body. But if material accumulates and isn\'t properly eliminated, our system is compromised. Cleansing the colon can relieve digestive problems like constipation and bloating. Even skin problems can be improved by regular colon cleansing. Colon hydrotherapy is a procedure that flushes out the colon with warm water. In colonic irrigation, a soft plastic tube is inserted in the rectum, and it takes very little time.
