Enemas and colonics can accomplish exactly the same beneficial work. But colonics accomplish more improvement in less time than enemas for several reasons. During a colonic from 30 to 50 gallons of water are flushed through the large intestines, usually in a repetitive series of fill-ups followed by flushing with a continuous flow of water. This efficiency cannot even be approached with an enema. But by repeating the enema three times in close succession a satisfactory cleanse can be achieved. Persisted with long enough, enemas will clean the colon every bit as well as a colonic machine can. Enemas given at home take a lot less time than traveling to receive a colonics at someone's clinic, and can be done entirely at you own convenience--a great advantage when fasting because you can save your energy for internal healing. But colonics are more appropriate for some. There are fasters who are unable to give themselves an enema either because their arms are too short and their body is too long and they lack flexibility, or because of a physical handicap or they can't confront their colon, so they let someone else do it. Some don't have the motivation to give themselves a little discomfort but are comfortable with someone else doing it to them. Some very sick people are too weak to cleanse their own colon, so they should find someone to assist them with an at-home enema or have someone take them to a colonic therapist. Few people these days have any idea how to properly give themselves an enema. The practice has been discredited by traditional medical doctors as slightly dangerous, perhaps addictive and a sign of psychological weirdness. Yet Northamericans on their civilized, low fiber, poorly combined diets suffer widely from constipation. One proof of this is the fact that chemical laxatives, with their own set of dangers and liabilities, occupy many feet of drug store shelf space and are widely advertised. Is the medical profession's disapproval of the enema related to the fact that once the initial purchase of an enema bag has been made there are no further expenses for laxatives? Or perhaps it might be that once a person discovers they can cure a headache, stop a cold dead in its tracks with an enema, they aren't visiting the M.D.s so often. The enema has also been wrongly accused of causing a gradual loss of colon muscle tone, eventually preventing bowel movements without the stimulation of an enema, leading finally to flaccidity and enlargement of the lower bowel. This actually can happen; when it does occur it is the result of frequent administration of small amounts of water (fleet enemas) for the purpose of stimulating a normal bowel movement. The result is constant stretching of the rectum without sufficient fluid to enter the descending colon. A completely opposite, highly positive effect comes from properly administered enemas while cleansing.
