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.

Preparation.—Take of rosin, 4 troy ounces; yellow wax, 1 troy ounce; tincture of capsicum, 1/2, pint. Melt the rosin and wax, and add the tincture; keep stirring by a gentle heat, until the alcohol is evaporated; then remove from the fire, and, when nearly cold, add pulverized camphor, 1/2 troy ounce; oil of sassafras, 45 minims. Stir until cold (Beach's Amer. Prac.).
Action and Medical Uses.—This forms a gently stimulating and strengthening plaster, and may be used in all cases where artificial support, prevention of the contact of atmospheric air, or mild stimulation is required. It was a great favorite with Eclectic physicians 25 years ago, and is still extensively used by them.
