Armadillo bile is the bile of an armadillo, which can be used as a potion ingredient, such as in the Wit-Sharpening Potion.


In March 1995, Harry Potter deliberately spilled his armadillo bile at the end of Potions class so he could eavesdrop on a conversation between Severus Snape and Igor Karkaroff about the Dark Mark while he cleaned it up.[2]
