köken: From Middle High German ingeweide, from earlier geweide, a word restricted to High German. Predominantly attributed to hunter’s jargon as a derivation from Weide (“food, pasture”), as some of the guts are thrown to the dogs. Alternatively related to Weide (“willow”), then in the sense of “something wound up, convoluted”; compare Latin viscera (“entrails”).
aile: Eingeweidebruch
[Das Monster] beißt Dir in den Hals und trinkt Dein Blut. Ohne Blut bist Du bleich wie Kreide; dann frißt es Deine Eingeweide.

köken: Borrowed from German Hormon. The sense “offal” originated from the names of some Taishō era cuisines that supposedly promote human health by "affecting hormones". Relation to the phrase "放(ほう)るもん (hōru mon, literally “things to throw away”)" is a folk etymology.
