"Erumpent horns, tails, and the Exploding Fluid are all used in potions, though classified Class B Tradeable Materials"
— Erumpent horn's use in potions[src]

An Erumpent horn is the horn of an Erumpent, a magical beast. The horn contains a fluid that causes whatever it is injected into to explode. They are highly prized as potion ingredients, but are listed as a Class-B Tradeable Material.[1]


The Erumpent Horn in the Lovegood House

Luna Lovegood's home was destroyed by an Erumpent horn that her father Xenophilius claimed to be the horn of a Crumple-Horned Snorkack. He proudly displayed it despite the warnings given to him by Hermione Granger, and he accidentally blew it up while trying to stop her, Harry Potter, and Ron Weasley from escaping Death Eaters shortly after Christmas in 1997.[2]

During the Calamity which affected the Wizarding world in the 2010s, Erumpent Horns were used as ingredients in the brewing of the Tonic for Trace Detection by wizards and witches of the Statute of Secrecy Task Force.[3]
