Bruise Cruse is a medicine that was mentioned on page 110 of Exile (paperback), when Sophie needed something to heal her wrist from when she went with Keefe to fix her abilities. Edaline had bought it for her along with Scratches 'n Splits, Abrasion Persuasion, and Blister Blast. In Everblaze, she ended up using Bruise Cruse for the burn on her wrist. When Sophie was rubbing it in, she noticed the yellowish sludge felt prickly because it was actually doing damage instead of healing. Eventually, she settled for scrubbing her wrist with soap and water. She mentioned that the cream made her burn worse.
