Despite the absolutely mind-blowing scientific developments we have witnessed in the last few decades, it seems like our ancestors still have the upper hand, as a 1000-year-old recipe for a treatment is effective against our worst medical nightmare: superbugs.
The instructions for said cure, found in the “Bald’s Leechbook” manuscript (written in the 9th Century), called for mixing garlic, leeks, wine, and bile from a cow’s stomach in a brass container, so that’s what scientists in Nottingham University, curious about the effectiveness of this old-fashioned procedure, prepared. There was one slight exception: brass containers are costly and difficult to keep bacteria-free, so instead they used a glass bottle and inserted brass sheets into the mixture hoping it would have the same effect. It was left for nine days to sit, producing a dominant garlic scent which filled the lab. But proof did eventually start to show that demonstrated this was more than child’s play: the bacteria that had been added through the soil in the garlic and the leek had been killed, meaning the solution was actually sterilising itself.
Originally, the concoction was thought out to treat styes (eyelash infections) which are caused by Staphylococcus aureus bacteria, supposedly working perfectly fine. But the reconstruction has now been tested on Methicillin-Resistant Staphylococcus aureus; the older, tougher sibling of the original bacteria and the mixture can still hold its ground. In an experiment using pieces of skin from infected mice, the centuries-old mixture cleared 90% of the MRSA infection; just as much as the standard modern antibiotic used for this type of bacteria.
What’s interesting to note is that only the mixture of all these compounds actually caused an effect on the bacteria. The scientists conducting this research carried out several repeats, each time changing the variables by using only one of the ingredients in a brass-containing water solution. By themselves, they were useless against MRSA, which was to expect because even though they all have some antimicrobial properties, this type of superbug is one of the hardest to kill. But when they were brewed together, they were able to almost completely massacre the culture. Although an explanation for why only their combined effects works is still missing, the frenzy of this wild event has caught many scientists from all around the world’s attention, and many experiments are currently being conducted in hopes of finding out the mechanism behind this ‘magical’ preparation.
This event just goes to show that although we may see most past scientists as delirious people who though the Earth was flat and there were only 5 elements, they still had some very promising ideas which should be remembered.
