What does cerate mean?
A cerate is a medicated ointment made by combining a wax — traditionally beeswax — with an oil or fatty substance such as lard or olive oil. The wax gives the preparation a firm but spreadable consistency, allowing it to cling to the skin and act as a soothing, protective dressing for burns, wounds, and irritated tissue. Cerates were staples of pharmacy for centuries, appearing under names such as 'simple cerate' in standard pharmacopoeias, and apothecaries routinely compounded them by melting wax and fat together and stirring in any required medicinal agents. With the rise of modern cream and ointment bases, the word has become largely historical, surviving mainly in older medical texts and discussions of traditional preparations. It derives from the Latin cera, meaning wax, which also gives us related terms such as cere. Though now uncommon, cerate remains a precise and evocative term for one of the oldest forms of topical medicine.
nounA medicated ointment or salve made by combining waxes (traditionally beeswax) with oil or fat, used on the skin for its soothing and protective properties.
- A medicated ointment or salve composed of wax combined with oil or fat, applied to the skin.

Long before modern creams came in tubes, apothecaries blended beeswax into 'cerates' — ointments literally named after the Latin word for wax.

Etymology of cerate
Cerate comes from the Latin cera, meaning 'wax', via forms such as Late Latin ceratum, referring to a waxed preparation. The word entered English in the early modern period through medical and pharmaceutical writing, when wax-based salves were standard items in the pharmacopoeia. It shares its root with other wax-related English words, including the verb cere (to coat with wax) and cerumen, the medical term for earwax.
How cerate is actually used
A technical term of historical pharmacy and medicine; rarely encountered outside older pharmacopoeias, medical history texts, or discussions of traditional remedies. It carries a formal, archaic register today.
