This blown and molded square glass bottle has a narrow neck, a flared lip, and a baked enamel cartouche surrounded by a floral arrangement. The label is marked in black Lumbric Alum UST and the alchemical symbol for Spirits. Lumbricor is dried and pounded earthworms, alum is potassium aluminum sulfate, and ustum is Latin for heated. This jar would have contained a spirits solution of heated alum and earthworms, which was often used as an emetic, astringent, or diuretic.
