Relating to or designed for rinsing or washing the mouth and throat.
From Latin 'colluere' (to rinse, wash) + '-ory' (relating to). The '-ory' suffix creates adjectives meaning 'serving for' or 'relating to a specific function.'
Medical texts from the 1600s-1800s are full of 'collutory' preparations—they were considered serious medicine, and apothecaries took them as seriously as we take toothpaste today, often insisting they had miraculous healing properties.
