The term high Enema is used to indicate a large volume enema that reaches deep into the colon. The term high colonic is sometimes used to indicate a high Enema. The enema usually consists of one to two quarts of water, sometimes with soap or mineral oil added. The recipient may be asked to move into different positions during the administration of the enema to facilitate the water reaching as high into the colon as possible. If a series of enemas are given to cleanse the entire colon, a colon tube may be used. In this process the colon tube is inserted farther than a regular enema tube or nozzle, usually 12 inches or more, with the tube being inserted farther into the colon with each successive enema. This requires care and patience, and should only be done by an experienced medical professional.
