After referring to its medicinal uses, he says: "the Horse Radish stamped with a little vinegar put thereto, is commonly used among the Germans for sauce to eat fish with and such like meates as we do mustarde." Where the English name horseradish comes from is not certain. It may derive by misinterpretation of the German Meerrettich as mare radish. Some think it is because of the coarseness of the root.
