Mishnah 6

One may anoint and rub the stomach with the bands, but not so as to cause fatigue. One must not brush the body with a flesh-brush or descend into a kurdima. One must not take an emetic, or stretch the limbs of an infant, or put back a rupture; one who has strained his hand or foot must not pour cold water on it, but he may wash it in the usual way: if he thereby becomes cured, it is Well.
