A mixture of 10 per cent, of ammoniated mercury with white petrolatum and hydrous wool-fat.

Action and Uses: Ammoniated mercury in the form of an ointment of from 2 to 10 per cent, is much used as an antiseptic and local stimulant. In the strength of from 3 to 5 per cent, it is an efficient and non-irritating application for small areas of suppurating dermatitis. In stronger proportions (from 8 to 12 per cent.) it is a useful stimulating ointment for exciting a healthy inflammatory reaction, as in psoriasis. In seborrhea it may be applied after removal of crusts, in the form of a 2 per cent, ointment.
