Emulsions arc aqueous preparations wherein oils or resins are maintained in a fine state of subdivision and suspension by means of the presence of mucilaginous or other viscid substances.

Prepare the official Emulsum Olei Terebinthinae as follows: Into a perfectly dry flask introduce 15 Gm. acacia, in fine powder; add 15 mils rectified oil of turpentine, and 5 mils expressed oil of almond, and agitate the mixture thoroughly. Next add 30 mils water, mixing this in with vigorous shaking. When emulsification is complete add 25 mils of syrup in 5-mil portions, shaking thoroughly between each addition. In the same manner, next add successive portions of water until the product measures 100 mils.

This preparation provides the best medium for administering "Spirits of Turpentine" in those rare instances where its internal use seems indicated. Dose, 2 mils.
