Since we are talking folklore here (and to the ‘grow up’ people, I say that the study of folklore is valuable because it forms such a huge chunk of our cultural development, even today), then NOT silver bullets. That’s Hollywood speaking, not folklore. Werewolves are recorded (initially as historical fact) as early as the first century AD, with the last recorded ‘werewolf trial’ taking place in Styria in the eighteenth century; silver bullets only become a thing with the release of ‘The Wolf Man’ in 1941. Silver IS connected to Werewolves, but since it is the ‘metal of the moon’ in purely magical terms it is no more effective against Werewolves than any other sort of bullet, and probably less effective than good old-fashioned lead, which is why we don’t make bullets out of silver as a matter of course (silver’s more abundant than people think). Silver was for Vampires. Traditionally for Werewolves you want aconite (also known as Monk’s Hood, or Wolfsbane – what a giveaway) or viscum album (mistletoe). There’s a reason why kissing under the mistletoe has become a Christmas tradition – in Medieval Europe, winter was wolf season, and a wolf walking abroad as a man would be unable to pass through a door over which mistletoe was hung. In some parts of Europe, Werewolves were believed to either put on a wolfskin or take off their human skin – and stealing and burning the discarded skin (wolf or human) would destroy the creature.
