To some the continuous use of the colon-flushing treatment is inclined to be debilitating and in rare cases complaints have been made that it dilates the colon and weakens its muscular structures. This is occasionally true in the case of the hot enema. A fairly cool enema is less objectionable, while a cold enema has a decided tonic effect in contracting and strengthening the peristaltic muscles. The cold enema is less effective as a cleansing agent, as it does not have the relaxing effect of the hot enema. In most cases an enema of neutral temperature, or at about that of the body, may be suggested, though if one has been using this treatment very much it would be better to use either a cool or cold enema, if strong enough, in order to secure its contracting and tonic effect. If the cold water causes cramps one should modify the temperature. Usually it is best to use plain water for the enema. In a case of illness where quick and radical results are required, a hot soap-suds enema may be suggested, but you should remember that this always has the effect of removing the natural oils and is inclined to leave the colon in an irritated condition. A saline solution is to be especially commended where there is a serious catarrhal condition of the intestines, or where there is much inflammation or irritation, such as might be manifested in extreme cases by bloody stools. For a normal saline solution use one teaspoonful of ordinary salt to a quart of water, or four teaspoonfuls to a four-quart enema. Glycerin is frequently suggested, but it is not to be generally recommended. If one follows these methods persistently, constipation, even in its most aggravated forms, can be overcome. In some instances almost any one of the suggestions offered will bring about the results desired, but in a chronic case one should depend not on one but on a combination of all of these various remedial measures. The improvement in the condition of your skin, in the purity of your blood, and in the degree of energy that you will enjoy will more than repay you for your efforts in following the various suggestions made for cleansing, strengthening, and vitalizing the alimentary canal.
