I need some help. In my story, one of the characters needs some kind of pain-killer for the plot. In the movie "Gladiator," the emporer's sister makes him some form of tonic or elixer to help him sleep. When I saw the film for the first time I was struck on how the use of the word was perfect for the scene. I cannot remember what it was! I've tried to find snippets of the movie showing that scene, and I've cross-checked my Thesaurus, but none of those words really fit my situation. Anyone know that word or remember the movie scene?
