Physiological Action. Feebly alkaline, the preparations of Calcium are mere astringent antacids. The actions of the phosphate have already been described. Syrupus Calcis is an antidote to Carbolic Acid, or Oxalic Acid poisoning.

Therapeutics. Lime-water is used in the summer vomiting of children, and is added to their milk when the latter is not well retained. Chalk mixture is prescribed in the diarrhoea of children, with sour-smelling watery stools. In Diphtheria and Croup, the vapors of slaking lime, or lime-water spray, are often very serviceable. Lime Liniment is a good application for burns.
