"Extremely runny nose"
—The spell's description in The Dark Forces: A Guide to Self-Protection.[src]

The Curse of the Bogies (Mucus ad Nauseam[1]), is a curse that gives the recipient a strong cold, that can make him or her collapse if not treated, as well as an extremely runny nose.[2] No further casts of this curse have any additional effect on the target, unless the Duo or Tria modifiers are used.

There exists a counter-curse of unknown incantation, and it is presumed a Pepper-up potion will cure effects as well.


Quirinus Quirrell mentioned it to his first-year class in 1991. Ron Weasley threatened to learn this curse, then use it on Hermione Granger and Neville Longbottom if they got him and Harry Potter caught roaming the school at night on their way to a duel with Draco Malfoy.[3] In the same school year, Harry Potter fell ill when Peeves used this curse on him. Harry had to look for Updated Counter-Curse Handbook in the library to perform the Counter-curse.[4]


"Ad Nauseam" is a Latin term meaning "to the point of nausea". This implies that the curse makes one produce mucus to the point of them feeling physically ill.
