Action and Medical Uses.—This plaster is stimulant, and may be employed where a mild counter-irritant is demanded, as well as for a strengthening or supporting plaster. Occasionally the pitch plaster will be found to cause, and keep up a discharge of serum, and when it does so, it should be often renewed.
