Quassia, Bitter Wood. In large doses (f.e., 30 I,) it acts as an emetic with some persons and is an anthel-mintic, but is seldom given in such doses. In small doses (f.e., 3 to 5 I,) it markedly stimulates all the glands concerned in digestion and increases intestinal peristalsis. It is highly useful in debilitated states of the digestive tract with inactivity of the secreting organs. Infusions of quassia, used as enemata, destroy worms in the lower intestinal tract, and, used upon the skin repeatedly, will kill pediculus capitis and pediculus pubis.
