Yes, I've heard of it as well, Jessie. There's no cure for the, err, disease of being a Werewolf but there's the Wolfsbane Potion which is a recent invension and should relieve some of the most harmful aspects of the werewolves. Still it doesn't help them go berserk when finding human beings, I've been told. (Its name is due to its main ingredient, the Wolfsbane, also known as aconite or monkshood)
