A kind of pyrogenous or empyreumatic oil, produced by the combustion of textures of hemp, linen, or cotton in a copper vessel. The brown product is acid. Its medical properties probably resemble those of creasote. Diluted with three or four times its weight of water, it has been used as a gargle in cynanche tonsillaris, but is not now employed. It is said, also, to be a popular remedy for toothach and skin diseases. When prepared from rags, it is called Rag oil; when from paper, Paper oil, (F.) Huile de Papier.
