What do you get when you mix leeks, garlic, wine and bull gall, then ferment it in a copper pot for nine days? In the Anglo-Saxon era, this concoction made a terrific treatment for eye styes but recently researchers have found it equally effective against the scourge of modern medicine: antibiotic-resistant MRSA "superbugs." Freya Harrison, a microbiologist at the University of Nottingham, UK working with Dr Christina Lee, an Anglo-Saxon expert from the School of English, found the ancient recipe in Bald's Leechbook, an Old English medical compendium. The two decided to test its against modern skin infections. Using the oldest heirloom vegetable varieties she could find, Harrison brewed up the recipe, then let it stand the requisite time. What she poured out displayed some incredible antibiotic characteristics.
