Love Potion Antidote

The Love Potion Antidote is a potion that cures the symptoms of the Love Potion. It is described as a clear liquid.

History
Horace Slughorn brewed some for Ron Weasley on 1 March, 1997 when he unintentionally ate some Chocolate Cauldrons spiked with Love Potion by Romilda Vane, which had fallen off of Harry Potter's bed and were mistaken by Ron as one of his birthday presents.

Behind the scenes

 * The potion is clear in the book, but on the film version the antidote is of a bright red colour. Yet, on the video game the potion is pink.
 * Although a love potion's effects will eventually wear off on their own, this antidote can be used as an expedient alternative.
 * A Hate Potion can also cancel out a Love Potion's effects, and vice versa.
 * It is unknown if each type of Love Potion has its own specific antidote, or all varieties can be cancelled out by one antidote.
