Remarks

Of all the mercurial preparations, the white precipitate, in the form of ointment, is the one most frequently employed as an external application in diseases of the skin. Its principal use is in connection with eczema, in non-infiltrated forms of which it is almost always of ser-oe. The officinal ointment is greatly improved by the addition of a little compound tincture of benzoin, or the Ungt. Benzoini may be substituted for the simple ointment.
