Senna is a mild cathartic; but its action is frequently attended with much tormina, and to some is very unpleasant. As it does not increase elimination by the bowels, its use as a cathartic is quite limited, and it may well be replaced by other remedies.
It exerts, however, a special influence in colic, which renders it an important remedy. We have generally employed it in the form of the Compound Powder of Jalap and Senna, in doses of five or ten grains, frequently repeated until relief is obtained. An infusion of Senna—or the tincture will answer the same purpose—for the relief of colic, whether the common wind-colic or that known as bilious, I regard as one of our best remedies.
