I kanon tror jag inte att Entrail-Expelling Curse någonsin nämns utanför HP och Phoenix-ordningen , kapitel 22. Allt vi vet är att det uppfanns av Urquhart Rackharrow på 1600-talet. Ordet "Curse" föreslår att det kan användas som ett vapen, men det faktum att hans porträtt hänger i det magiska sjukhuset i St. Mungo s suggestar att det har någon medicinsk tillämpning.

The term "entrail-expelling" is not something most people would like to think about, much less study. Another word often used to describe the same thing is "disembowelment." You might recall that Snape made Neville "disembowel" a barrel full of horned toads as a detention once -- not a pleasant task (GF14). While disemboweling creatures might be useful in potions-making - getting armadillo bile also comes to mind (GF26) - there are not many good reasons for wanting to remove entrails from humans while they are still alive, except for torture. Also the fact that it is a "curse" makes it sound even more terrifying. Since Urquhart Rackharrow was apparently some type of healer to be honored with a portrait at St. Mungo's, let's hope there was a humane surgical reason for using such a "harrowing" spell. Or perhaps Rackharrow studied bodies after death as a coroner or forensic pathologist.
