Preparation.—"Oleoresin of capsicum, resin plaster (contains lead), each, a sufficient quantity. Melt the resin plaster at a gentle heat, spread a thin and even layer of it upon muslin, and allow it to cool. Then, having cut off a piece of the required size, apply a thin coat of oleoresin of capsicum, by means of a brush, leaving a narrow, blank margin along the edges. A space of ten centimeters (10 Cm.) [3.94 inches] square should contain about twenty-five centigrammes (0.25 Gm.) [3.85 grains] of oleoresin of capsicum"—(U. S. P.).

Action and Medical Uses.—This plaster is stimulant and slightly rubefacient. It may be applied where a mild counter-irritant is needed in neuralgic, rheumatic, and other painful conditions.
