Oxymel

According to Scientific American, recently the mixture has been used successfully in a biofilm for topical uses on wounds where bacteria has become resistant to antibiotics, both ingredients having been used historicaly as antiseptics, but the combination was reported as killing as much as 1,000 times more bacteria than vinegar alone and as much as 100,000 times more than honey alone in biofilms.

[1] Its name is often found in Renaissance (and later) pharmacopoeiae in Late Latin form as either a countable or uncountable noun.

Fit vinum ex aceto & melle quod oxymel vocaverunt voce Graecanica.

Mellis decem librae cum aceti heminis quinque, haec decies subserve faciunt atque ita sinunt inveterare.

Est autem hydromel vinum ex aquae & melle confectum, unde & nome.
