Cerium oxalicum

Natural History.
      Oxalate of Cerium. Ce2(C2O4)3 9H2O. Trituration.

      Cough, reflex, Dysmenorrhoea Pregnancy, vomiting of.

      Originally introduced by Sir James Simpson as a remedy for the morning sickness of pregnancy and chronic cases of vomiting, which he supposed to be due to some eruption on the mucous membrane of the stomach, Cer-ox., has fairly maintained its reputation.
      Hale found it of most use in cases of vomiting of half-digested food.
      It was mostly been given in lower triturations by homeopaths, and in five to ten grain doses by allopaths.
      In the latter doses it has produced decidedly narcotic effect in two cases.
      Some have obtained great success with it in sea-sickness.
      Spasmodic coughs of nervous or reflex origin have been successfully treated with it, and dysmenorrheal in fleshy and robust women, scanty flow, pain coming before, or at commencement, with feeling of tenesmus, better when the flow is established (like Lach.).
