The milk cure consists in feeding sick people on nothing but milk for varying periods. Generally the patient is told to either take great quantities three or four times a day, or to take smaller quantities perhaps every half hour. The milk cure has no special virtue, except that it is a monotonous diet. The body soon rebels if forced to subsist on an excessive amount of but one kind of food. The individual loses his desire for food and even becomes nauseated. If the advocates of the milk cure would prescribe milk in moderation, instead of in excess, they would have better success. (It is fully as harmful to partake of too much milk as it is to eat excessively of other foods.) The benefit derived from the milk cure comes from the simplicity, not from the milk. A grape cure, an orange cure or a bread and milk cure would be as beneficial. The milk cure is ancient. It was employed twenty-five centuries ago. _Clabbered milk_: Clabbered milk or sour milk needs no special preparation. Put the milk into an earthen or china dish. Do not use metal dishes, for the lactic acid acts upon various metals. Cover the dish so as to keep particles of matter in the air away, but the covering is not to be airtight. Put the dish in a warm place, but not in the sun. Milk that sours in the sun or in an air-tight bottle is generally of poor flavor. Clabbered milk is a good food. It does not form big, tough curds in the stomach, it is easy to digest, and the lactic acid helps to keep the alimentary tract sweet. The various forms of milk may be used in similar combinations. _Buttermilk_: The real buttermilk is what remains of the cream after the fat has been removed by churning. It is slightly acid and has a characteristic taste, to most people very agreeable. The flavor is different from that of artificially made buttermilk. In composition it is almost like whole milk, except that it contains very little fat. Many people make buttermilk by beating the clabbered milk thoroughly, until it becomes light. The buttermilk made from sweet milk and the various brands of bacterial ferments obtainable at the drug stores is all right. These ferments have as their basis the lactic acid bacteria, and if the manufacturers wish to call their germs by other names, such as Bacillus Bulgaricus, no harm is done. It is unnecessary to add any of these ferments, for the milk clabbers about as quickly without them. Buttermilk is an excellent food. The casein can be seen in fine flakes in the real buttermilk. Adults usually digest buttermilk and clabbered milk more easily than the sweet milk. The lactic acid seems to be quite beneficial. Metchnikoff thought for a while that he had discovered how to ward off decay and old age by means of the lactic acid bacteria in milk. Milk can be clabbered quickly by adding lemon juice to sweet milk.
