Unguentum Adipis, U. S. 1860; Unguentum Simplex; Pommade simple, Fr.; Unguentum cereum, P. G. Wachssalbe, G.
"White Wax, two hundred grammes [or 7 ounces av., 24 grains]; Benzoinated Lard, eight hundred grammes [or 28 ounces av., 96 grains], to make one thousand grammes [or 35 ounces av., 120 grains]. Melt the white wax, add the benzoinated lard, and heat gently until liquefied; then stir the mixture until it congeals. For use in southern latitudes and during the warm season in other localities, 50 Gm. of the benzoinated lard (or more if necessary) may be replaced by an equal quantity of white wax." U.S.
Yellow wax was used in this ointment in the U. S. P., 1890, and objection was made to the color of the ointment. It has been very properly replaced by white wax in the U. S. P. VIII and IX, and the lard is now benzoinated.
This is emollient, and is occasionally employed as a mild dressing to blistered or excoriated surfaces, but more frequently as a vehicle, it being the basis of several official ointments.
