This blown and molded square–shaped bottle has a baked enamel white oval cartouche that is outlined with blue vines, red and yellow flowers, and a three-pointed crown. The cartouche is marked EL ACID H. The jar would have contained Electuarium Acidum, or Acid Electuary. Electuaries were pastes often made into lozenges. This lozenge, made with sorrel and cream of tartar, was used to treat jaundice, a yellow tinge of the skin caused by excess bilirubin in the blood.
