The presence of from three to four quarts of water in the body will naturally distend the abdomen and produce a little discomfort, but no apprehension of any harmful result need be entertained. Rest assured of this: it is absolutely impossible to rupture the colon, unless you were to use a force pump, and even then, before the point of rupture could be reached, the pain would be so intense that you would be compelled to desist. Again, as we have pointed out, the colon is a wonderfully elastic organ, and it would be an impossibility to distend it with water to the same extent that it is frequently distended by fæcal accumulations. Whenever pain is present during the treatment it is usually due to one of two things: either the water has not been sufficiently hot, or the reservoir has not been completely filled, but, if in spite of these precautions, pain should be present, it will be found advisable, after a small quantity of water has been injected (say from a pint to a quart) to shut off the faucet, rise from the “Cascade” and expel it; then, upon returning to the “Cascade,” it will usually be found that the cleansing of the lower portions of the bowel has removed the trouble. The same method of procedure holds good when there is any difficulty in injecting the water. In cases where pain is persistent, even although all precautions are taken (although such are extremely rare), a decoction of anise seed, made by steeping a tablespoonful of the seed in a pint of boiling water, added to the water used for flushing (omitting the antiseptic tonic), will act as an anodyne on the intestine, and completely subdue the pain. The frequency with which the treatment is used will depend upon the nature of the trouble and the length of time it has existed. In the great majority of cases it is recommended to be used as follows when commencing the treatment: The first week use it every night; the second week every alternate night; after that use it twice a week, or as occasion seems to demand it. For the simple preservation of health, twice a week will be found amply sufficient. After using the “Cascade” it will be found extremely beneficial to inject from a half pint to a pint of cool water and retain it. This will be found not only a valuable rectal tonic, but an excellent diuretic as well, as it will pass off by way of the kidneys, cleansing and purifying those organs.
