Treatment of Croup
Every mother knows those fearful premonitory symptoms of croup, the hoarse sepulchral cough which is so startling. The child should be at once taken up, its throat and chest rubbed thoroughly before a hot fire with lard and camphor melted together, then a wet compress put on, by folding up a cloth of a half dozen thicknesses, (have it about two or three inches in width,) wring it out of cold water, then pin it on to a piece of flannel, allowing the flannel to extend beyond it on either side at least an inch, pin it securely around the neck placing another piece of flannel or a soft towel out side, entirely excluding the air. If the child is very much oppressed give sufficient ipecac (syrup) to vomit it ; these remedies can be used until you have time to secure a physician. If the child continues t© be hoarse, continue giving ipecac all the next day every two hours not enough to vomit it, but sufficient to keep the phlegm loose. Another remedy for croup is alum, about one-half teaspoonful of pulverized alum in a small quantity of molasses, repeat the dose every hour until the patient is relieved ; or alum dissolved in water, and given in small doses every hour. Onion syrup is also very good for hoarseness in children ; put two or three onions in a pan, place them in the oven of the stove, let them get thoroughly baked, then squeeze the juice out into a saucer, and to every spoonful of juice put the same of white sugar, and give the child a teaspoonful every hour or oftener if necessary.
