Cerates are unctuous fatty preparations, similar to ointments, but having a higher melting point, and not liquefying at the body temperature.

Prepare the official Ceratum as follows: By the heat of a water bath melt 30 Gm. white wax, add 70 Gm. benzoinated lard; continue heat until all is melted; strain through thin cheesecloth, and stir constantly until the mixture congeals. (For hot localities a greater percentage of wax may be necessary.)

How does the consistency of the Cerate compare with an ointment ?........................................

Two other Cerates are official: Ceratum Cantharidis, which belongs to a discarded therapeutics; and Ceratum Resinae, used in making Linimentum Terebinthinae.
