Diapalma

In pharmacology, diapalma (from Lat dia, "made of" + palma, "palm"[1]) is a desiccating or drying plaster, named for the wood of the palm tree, from which the spatula is made that is used to stir the mixture while boiling.[2] It was formerly composed of common oil, hogs-fat, and litharge of gold;[2] or also of palm oil, litharge, and zinc sulfate. Now, it is made of white wax, emplastrum simplex, and sulfate of zinc.[1]
