A Detergent Gargle.
It deterges, and scours off thick Viscosity, and slimy Nastiness sticking to the Tongue, and parts of the Mouth; humects and refrigerates the Throat, when dry'd up and parch'd; corrects the muriatic Acrimony of the Saliva, and extinguishes Thirst. But in Case of a sore Thrush, Erosions, and little Exulcerations, 'twill cause such a smarting, that it can be scarce born:
And then we must have recourse to Refrigerates Moisteners, Emollients, Mucilages, and Astringents.
