Belch Powder

Belch Powder is a joke product that presumably causes the user or victim to begin burping. It was available in Hogsmeade, most likely at Zonko's Joke Shop.

Ingredients for Belch Powder included Mummy, Mastick, Red Myrrhe, Olibanum, Ammoniacum, Oppopanax and Bdelium (2 drachms of each), 2 pounds of Vitriol, 2 pounds of Honey, half an ounce of Tartar, and 3 gallons of Aquavitæ.

Behind the scenes

 * The ingredient list for the Belch Powder boxes, as featured in Harry Potter Wizard's Collection seem to have been copied directly from a 1656 copy of The Archidoxes of Magic, by Paracelsus. The excerpt in question is actually a list of ingredients for a "Celestial Medicine" against the gout.
