Nosebleed Nougat

Nosebleed Nougat is a type of sweet made by Fred and George Weasley in their Skiving Snackbox. The sweet is designed to made the eater's nose bleed heaveily within seconds of eating it.

One Quidditch practise in Harry's fifth year; Katie Bell got a nose bleed when playing and Fred gave her what he thought was the cure for a nose bleed(the purple sweets) but evidently gave her the orange one which made it worse. Fred and George had to take her to the Hospital wing and the practise was cancelled.
