2. Mercurial ointment 2 oz. Olive oil and camphor, of each 2 dr. Embrocations of a more stimulating kind are sometimes employed in swellings of the joints, old strains or other local affections, such as soap liniment with liquid ammonia, olive oil, oil of turpentine, and liquid ammonia, but blisters in such cases are generally more effectual. Embrocations are often improperly employed, as in recent strains, or inflamed tumours, and other cases where emollient or cooling applications are required. Both strains and bruises are, at first, attended with a degree of inflammation, proportionate to the violence of the injury, and the susceptibility of the injured part; therefore they require, at first, such treatment as is calculated to subdue inflammation, that is, bleeding and purging with a suitable diet, and in strains, rest. The local or topical remedies in the inflammatory stage, are poultices, but in these cases bleeding and purging, immediately after their occurrence, are an essential part of the treatment.—_White._ EMERY, _s._ An iron ore, useful in cleaning and polishing steel. EMMET, _s._ An ant, a pismire. EMOLLIENT, _a._ Softening, suppling. EMOLLIENTS, _s._ Such things as sheathe and soften the asperities of the humours, and relax and supple the solids. _Vide_ POULTICE and FOMENTATION.
