The general properties of koumiss and Kephir are given on p. 44, Koumiss contains from 1 to 2 per cent of alcohol. Ft is more easily digested and more completely absorbed than ordinary milk, and can be taken in large amounts. It is diuretic, gently laxative, and, like other milk cures, lessens intestinal putrefaction in virtue of the lactic acid which it contains. On an average from 2 to 4 quarts are taken daily, but much larger quantities are taken at the special "cure " resorts in Russia where this method is in vogue. The koumiss is given in combination with nourishing food of a protein nature, carbohydrates, fruits, and saccharine foods being specially restricted. Lime-water is added if diarrhoea is present. This koumiss cure is largely employed in Russia in the treatment of pulmonary tuberculosis. In this country the special value of koumiss lies in its being a valuable milk preparation, which can be taken by many patients with whom plain milk and its other modifications disagree. For this reason it is a most useful foodstuff in the treatment of many derangements of the stomach and bowel, either of a primary nature or as occurring in affections of the heart or lungs.
