Oxymel

Oxymel (fromLatin, meaning "acid and honey", fromAncient Greek ὀξύς, meaning "acid",and μέλι, meaning "honey") is a mixture of honey and vinegar, used as a medicine.

Its name is often found in Renaissance (and later) pharmacopoeiae in Late Latin form as either a countable or uncountable noun. As a countable noun, it is spelled variously as (singular) oxymellus and oxymellis, and plural oxymeli and oxymelli.
