Measles, Lemon Remedy from a Canadian Mother

"Give child all cold lemonade it can drink and keep in warm room. This acts just as well as if the drinks are hot. We tried both on our children and cured both ways." Don't give so much of the cold as to chill. The cold drink makes child sweat, just as hot does. Also helps to carry off impurities by flushing bowels, just as clear water would.
