Morphology
Dover's + powder
This is a named, historical medicinal preparation: 'Dover's' is an eponym/proper name and 'powder' only indicates the physical form. A B1 learner who knows 'Dover' and 'powder' would not be able to infer the specific medical composition or use (ipecac + opium, used to relieve pain/induce sweating), so the meaning is encyclopedic/idiomatic rather than compositional.
Etymology
Dover's powder is named after an English doctor, Thomas Dover, who sold a small powdered medicine in the 1700s. The powder made people 'sweat' and helped 'relieve pain', so the name became the common word for that remedy.
