Homorphus Charm

The Homorphus Charm is briefly discussed in chapter 10 of Harry Potter and the Chamber of Secrets, where Professor Lockhart tells the tale of rescuing a village from the Wagga Wagga werewolf to Harry Potter. It is again mentioned in chapter 16 when Professor Lockhart admits to stealing the credit from an Armenian Warlock. It is a matter of debate amongst Harry Potter fans whether or not this charm actually exists or if Gilderoy Lockhart made it up. The fact that Lockhart implies (in chapter 10) that the charm cures werewolves makes its existance extremely suspect to the point of being almost unquestionably false.
