A 1,000-year-old treatment for eye infections could hold the key to killing antibiotic-resistant superbugs, experts have said.
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.
The remedy was found in Bald’s Leechbook – an old English manuscript containing instructions on various treatments held in the British Library.
Anglo-Saxon expert Dr Christina Lee, from the University of Nottingham, translated the recipe for an “eye salve”, which includes garlic, onion or leeks, wine and cow bile.
Experts from the university’s microbiology team recreated the remedy and then tested it on large cultures of MRSA.
The leechbook is one of the earliest examples of what might loosely be called a medical textbook. It seems Anglo-Saxon physicians may actually have practiced something pretty close to the modern scientific method, with its emphasis on observation and experimentation.
Bald’s Leechbook could hold some important lessons for our modern day battle with anti-microbial resistance.
In each case, they tested the individual ingredients against the bacteria, as well as the remedy and a control solution.
They found the remedy killed up to 90% of MRSA bacteria and believe it is the effect of the recipe rather than one single ingredient.
Dr Freya Harrison said the team thought the eye salve might show a “small amount of antibiotic activity”.
“But we were absolutely blown away by just how effective the combination of ingredients was,” she said.
Dr Lee said there are many similar medieval books with treatments for what appear to be bacterial infections.
She said this could suggest people were carrying out detailed scientific studies centuries before bacteria were discovered.
The team’s findings will be presented at the Annual Conference of the Society for General Microbiology, in Birmingham.
While FoodFacts.com does understand that our ancestors used leeches to “suck out” infections (which was not only nasty,painful, and useless but likely also unsanitary), they also turned to the natural world around them for medication. It’s an idea that scientists and physicians are getting back to in their research. We’re pretty sure modern medicine and science will continue to find more surprising efficacy from old medicine texts like this one.
Hippocrates was definitely on to something. Food medicine can kill MRSA, which is sometimes referred to as a “superbug” because of its drug resistance. What else can it do?
We’re looking forward to finding out!
