Now this is interesting - MRSA relief from the 10th century

Anglo-Saxon eyesalve cuts swath through bacterial biofilms
One of my all-time favorite stories has an update. In 2015, microbiologists at the University of Nottingham collaborated with an Anglo-Saxon expert from the university’s English department to recreate a 10th century recipe for a salve purported to treat eye infections. The combination of onion, garlic, wine and bovine bile steeped together in a bronze or brass vessel was then tested on flourishing cultures of Methicillin-resistant Staphylococcus aureus (MRSA) and found to be a MRSA-killing machine. The individual ingredients did nothing; the control batch minus the vegetable ingredients did nothing. The full salve obliterated 999 Staphylococcus cells in 1,000, both for in vitro cultures and in vivo on infected mice. Even a diluted version of the salve was a powerful weapon. It couldn’t kill MRSA, but it blocked the bacterial cell-cell communication it needs to damage tissue.

The results were exciting but the research was in its infancy five years ago. Now the team has published a new paper on the use of Bald’s eyesalve on a range of pathogens in biofilms, communities of bacteria that form a protective shield that is to all intents and purposes impossible to destroy no matter how many antimicrobials you launch at it. Most pharmacological studies of plant ingredients focus on isolating active compounds and using them against planktonic (free-living) bacteria cells which are easier to kill than biofilms. This study explored the antimicrobial properties of the mixture

This is major and the chemicals involved (bovine bile) are available as standard reagents from a chemical supply house (Sigma Aldrich - $50 for 25 grams) Links to the two papers (as well as the original 10th century source) are in the post and the first two are very readable and give the proceedure for making the salve. Interesting. I can see an order to Aldrich in the offing - something to keep in the prepper's arsenal.
