The Aromatic Powder of the U. S. P. IX does not differ essentially from that formerly official. The British and American powders now closely resemble, each other. The U. S. process contains nutmeg and the British does not. The cardamom seeds should always be deprived of their pericarps before being weighed, and the powder, when prepared, should be kept in well-stoppered bottles.

Uses.—The aromatic powder is stimulant and carminative, and the U. S. preparation may be given in the dose of from ten to thirty grains (0.65-2.0 Gm.), in cases of enfeebled digestion with flatulence; but it is chiefly used as a corrigent and adjuvant of other medicines. A mixture of aromatic powders in the form of a cataplasm is much used as a mild rubefacient, especially in nausea and vomiting, being applied over the epigastrium. Such a mixture is commonly called spice plaster and will be found in the N. F. IV (Part III), under the title Pulvis Aromaticus Rubefaciens. It contains clove, cinnamon, ginger, and capsicum, and the mixed powder may be distributed in a thin flannel bag, quilted in position, and the whole wet with bathing whisky when applied and covered with oiled silk.

Aromatic Sugar.—Wm. L. Turner proposed a mode of obtaining the effects of the aromatic powder in certain cases where the use of the powder itself would be inconvenient. He prepared an aromatic sugar by submitting eight ounces of the freshly prepared powder to percolation with. stronger alcohol to exhaustion, pouring the percolate over eight ounces of sugar, and evaporating at a low heat. The sugar thus prepared may be added to mixtures, solutions, etc., requiring aromatic addition. (A. J. P., 1869, p. 118.)

Dose, ten to twenty grains (0.65-1.3 Gm.).
