The Douche Bath. THIS is the most powerful, but not the most useful of all the hydropathic appliances. A common douche consists of a stream of water from one to two inches in diameter, with a fall of five to ten feet. But douches may be arranged of any desirable size and height. (Fig. 189.) This remedy is useful in paralysis, stiff joints, gout, rheumatism, tumors, and old swellings of various kinds. Those who have weak lungs, stomach, or other abdominal organs, should not resort to the douche without the best of medical advice.
