Counter-curse

A counter-curse is a type of Counter-spell designed to remove the effects of a curse.

Known uses

 * In 1991, Professor Snape used a counter-curse to protect Harry Potter from a jinx put on his broom by Professor Quirrell, who was trying to knock him off.
 * Also in 1991, Seamus Finnigan said he knew the counter-curse to the Leg-Locker Curse and was about to use it on Neville Longbottom when he was interrupted by Hermione Granger.
 * In the 1996-1997 school year, Harry Potter used Liberacorpus, the counter-spell of Levicorpus (a spell he found in the Half-Blood Prince's book), on Ron Weasley, in the Gryffindor Boys' Dormitory.

Debatable occasions

 * In 1992, Gilderoy Lockhart claimed that he knew the counter-curse to prevent the Transmogrifian Torture. Due to his dishonesty, it is debatable if such counter-curses exist to begin with.

Behind the scenes

 * Gilderoy Lockhart claimed that he knew the counter-curse to prevent the petrification (in the second film), as opposed to the Transmogrifian Torture (in the novel), although there is a great chance that he was simply trying to inflate his reputation, as he is known for a great ineptidude for magic and probably does not know the counter-curse.
