Related entry: Myrrha (U. S. P.)—Myrrh
Preparation.—Take of myrrh, in powder, ½ ounce; acetate of zinc, 1 ½ drachms; acetate of lead, ½ drachm; water, 2 pints. Add the myrrh to 1 ½ pints of water, and boil together for 10 or 15 minutes; when cold, add the rest of the water in which the lead and zinc salts have been previously dissolved. Let them stand 24 hours and filter. If necessary, add enough water to pass through the filter to make 2 pints of the lotion (J. King).
Action and Medical Uses.—Compound myrrh lotion was formerly employed in cases of chronic ophthalmia. It will, however, be found useful in all chronic mucous diseases. It is usually applied 3 or 4 times a day, and must not be used during the presence of inflammation. When too severe, it may be diluted with water.
