As Outlander fans know, Claire Randall sterilizes the wound of young Jaime, a Jacobite fighter in the first episode of the show (and in the books, of course).
On Saturday on my ongoing Outlander field trip with VisitScotland we paid a call to Roddy MacRae a historical interpreter at the Highland Folk Museum.
Roddy told me that the Highlanders would indeed not have known what "germs" were, but they might have known enough to douse their wounds with whiskey. Water sources were often not to be trusted and people drank milk, whiskey, heather beer and other beverages but hardly ever plain water.
Stay tuned for more Highlander trivia along the Outlander trail.
