Preparation.—Take of lard 7 ½ ounces, resin 1 ½ ounces, yellow wax 3 ounces, fluid extract of savin 2 ounces. Melt together the lard, resin, and wax, and when nearly cold, having stirred it constantly, add the fluid extract, and continue the stirring to completion.
Action and Medical Uses.—Savin cerate is applied to blistered surfaces, to maintain a constant discharge. It is less irritating than the cerate of cantharides, and has no tendency to excite strangury. When well prepared it has a fine green color, is uniform and transparent, without any tendency to separate, and has a smell like that of the plant.
