What we found was very interesting -- we found that Bald's eyesalve is incredibly potent as an anti-Staphylococcal antibiotic in this context, we were going from a mature, established population of a few billion cells, all stuck together in this highly protected biofilm coat, to really just a few thousand cells left alive. This is a massive, massive killing ability.

I still can't quite believe how well this 1,000-year-old antibiotic actually seems to be working, when we got the first results we were just utterly dumbfounded. We did not see this coming at all.

The Middle Ages are often seen as the 'Dark Ages' -- we use the term 'medieval' these days ... as pejorative -- and I just wanted to do something that explains to me how people in the Middle Ages looked at science.
