Presumably causes hiccups
- "Malfoy was already packing up, sour-faced; Slughorn had pronounced his Hiccoughing Solution merely 'passable'."
The Hiccoughing Solution is a potion that presumably causes hiccups. Draco Malfoy brewed some when Horace Slughorn asked his sixth year Potions students to make something "amusing," but Slughorn was unimpressed with Draco's work, declaring it only "passable."
