Just came across this news story from March.
"Scientists recreated a 9th Century Anglo-Saxon remedy using onion, garlic and part of a cow's stomach.
They were "astonished" to find it almost completely wiped out methicillin-resistant staphylococcus aureus, otherwise known as MRSA.
Their findings will be presented at a national microbiology conference."
Go, Bald! Onion, garlic and cow's stomach, eh? And early practitioner of the scientific method? Well, I suppose modern science is woefully lacking in techniques to deal with all those problems caused by malevolent elves, for a start.
