Sweet Orange Juice. The juice of the orange is a light refrigerant article of diet, and is especially useful where the bowels are sluggish in action, and during convalescence from illness, as well as to be given during fevers and the exanthemata where acids are craved. It is par excellence the remedial agent in scurvy of infants, as well as adults, and if given early will abort this unpleasant disorder. Like all acids, orange juice is best indicated when the patient's tongue is deep-red or coated brown, black, or any intermediate color.
