Argus Filch: "What are you doing?"
Harry Potter: "Nothing."
Argus Filch: "Nothing! A likely story! Sneaking around on your own -- why aren't you in Hogsmeade buying Stink Pellets and Belch Powder and Whizzing Worms like the rest of your nasty little friends?"
— Filch grilling Harry about why he wasn't in Hogsmeade.[src]

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.[1][2]

Behind the scenes

  • The ingredient list for the prop Belch Powder boxes featured in the Harry Potter films 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.
