The Official Salt Of Cerium (Cerium) Is The Oxalate, Ce2(C2o4)2

10H2O, an inert powder, insoluble in water. The commercial article is very impure. Its action is practically that of the insoluble bismuth salts in allaying gastric and intestinal irritation, but its therapeutic use is mostly to check nausea and vomiting. Baehr and Wessler (1909) found it non-poisonous to dogs even in doses of 50 grams (1 2/3 oz.). They noted also that its action was mechanical as a protective to the gastric mucous membrane, and that it would check the vomiting from stomach irritants; but that it had no influence on the vomiting brought about by apomorphine, which is a central emetic. They found the usual dose entirely too small for protective purposes, and recommend doses of 30 to 60 grains (2-4 gm.). A mixture of cerium oxalate, 5 grains (0.3 gm.), and sodium bicarbonate, 10 grains (0.7 gm.), has frequently been employed in refractory cases of nausea and vomiting, as in pregnancy. It may be given with water, or added to a glass of milk and the milk fed in small quantities at a time.
