BUTTERMILK
In many cases of chronic intestinal indigestion, buttermilk is used in place of the milk. It is prepared as follows: After the cream has been taken from the milk and it has been allowed to come to a boil, it is cooled to just blood heat. A buttermilk tablet, having first been dissolved in a teaspoonful of sterile water, is now stirred into the quart of warmed, skimmed milk and allowed to stand at room temperature for twenty-four hours at which time it should look like a smooth custard. With a sterile whip this is now beaten and is ready for the sugar and the boiled water which is added according to the written prescription from the doctor.
