It will do you no harm to keep close, drink nothing but demulcent barley-water and eat gruel, thin gruel—no beef or mutton, no wine or spirits.
-- Patrick O'Brian, Master and Commander
She knew where sour grass grew, which you chew for dyspepsy, and mint, excellent for the nau-shy, and the slippery elm, whose fragrant inner bark was the favorite demulcent of a hundred years ago—the thing to use for raw throat and other sore tishas.
-- James Thurber, Writings and Drawings
Demulcent comes from the Latin word dēmulcere which meant "to soften."
