Oxymel

Oxymel (from Latin 'acid and honey', from Ancient Greek ὀξύς 'acid' and μέλι 'honey') is a mixture of honey and vinegar, historically 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.
