2490. Therapeutic Uses

In habitual Constipation, in the Con-stipation of Pregnancy, and in the Puerperal State, Senna, particularly in the form of the Confectio SennAe (the old Lenitive Electuary), proves a mild and efficient purgative. It is of an agreeable flavour, does not leave constipation subsequently, and causes vent slight excitement.

2491. In Bilious Derangements and Visceral Obstructions, the infusion of Senna {ante), in doses of fl. oz. j. - fl. oz. iij., either alone or combined with the Sulphate of Magnesia (gr. cxx. - gr. ccclx.) or the Tartrate of Potash (gr. lx. - gr. cxx.), forms an efficient purgative. It is best given in the morning, a mild mercurial being taken the night previously. The routine practice of "Blue Pill and Black Draught" is now, happily, almost discarded; but when judiciously given, it proves, in many instances, a safe and efficient plan of treatment. The habitual use of these remedies cannot be too strongly condemned. When the patient's condition will admit of free purging, Dr. Graves* considers that the infusion should be given in doses varying from fiij. to fvj.

2492. In Atonic Dyspepsia, particularly when attended by constipation, a mixture of equal parts of the infusions of Senna and Gentian proves eminently serviceable. It proves an efficient purgative in Atonic Duodenal Dyspepsia.
