A 1,000-year-old natural remedy made from onion, garlic, wine and bile salts has shown antibacterial potential.
Known as Bald's eyesalve, the treatment has the potential to tackle biofilm infections --- communities of bacteria which resist antibiotics.
The medieval concoction was first identified as being of potential help in the battle against superbugs in 2015, and the latest study in the journal Scientific Reports has shed more light on how it works and how it might be applied in practice.
The concoction was among the recipes for medicines, salves and treatments in "Bald's Leechbook," an Old English leatherbound book held in the British Library. It's one of the earliest known medical texts.
