We prefer the coriander of the U. S. P. 1870 to the ginger of the British. The infusion deposits, on exposure to the air, a yellowish precipitate, which is said to aggravate its griping tendency; it should, therefore, not be made in large quantities. It is customary to prescribe with it manna and some one of the saline cathartics, which increase its efficacy and render it less painful in its operation. (See Infusum Sennae Compositum.) The cold infusion, especially if made by percolation from the coarsely powdered leaves, while probably not inferior in strength to that prepared with boiling water, is said to be less unpleasant to the taste.
Dose, two fluidounces (60 mils).
