William Thomas Fernie, Herbal Simples Approved for Modern Uses of Cure
“ The Latin name Nasturtium was given to the Watercress because of its volatile pungency when bruised and smelt; from nasus, a nose, and tortus, turned away, it being so to say, "a herb that wriths or twists the nose." For the same reason it is called Nasitord in France. When bruised its leaves affect the eyes and nose almost like mustard. They have been usefully applied to the scald head and tetters of children. In New Zealand the stems grow as thick as a man's wrist, and nearly choke some of the rivers. Like an oyster, the Water-cress is in proper season only when there is an "r" in the month. ”
