Throat lozenge

A pocket tin containing small salmiak liquorice pastilles in the traditional diamond shape lozenge. In Europe, salmiak liquorice pastilles are considered a "traditionally-applied medicine to assist expectoration in the airways"

A throat lozenge (also known as a cough drop, sore throat sweet, troche, cachou, pastille or cough sweet) is a small, typically medicated tablet intended to be dissolved slowly in the mouth to temporarily stop coughs, lubricate, and soothe irritated tissues of the throat (usually due to a sore throat or strep throat), possibly from the common cold or influenza. Cough tablets have taken the name lozenge, based on their original shape, a diamond.
