"Erumpent horns, tails, and the Exploding Fluid are all used in potions, though classified Class B Tradeable Materials."
Newton Scamander, Fantastic Beasts and Where to Find Them

Exploding Fluid is found in the horn of the Erumpent. It causes anything that is impregnated with it to explode. It is highly valued as a potion ingredient, and is listed as a Class B Tradeable Material.[1]


In 1998, an Erumpent horn in the Lovegood House was struck by a Stunning Spell. This caused the fluid inside to explode, causing significant damage to the dwelling.[2]
