Death has been caused by the wilful administration of this acid, and by horses eating the leaves of mangel-wurzel, in which it is generated by fermentation while lying in heaps. The symptoms are similar to those produced by corrosive mineral acids (p. 46), and it is besides a powerful cardiac depressant.

Treatment

Frequent doses of saccharated carbonate of lime, lime-water, or whitewash. These are chosen because they form insoluble salts with oxalic acid, while those alkaline bicarbonates recommended for poisoning by other acids are forbidden because combining to form soluble oxalates, which are little less injurious than oxalic acid.

Oleaginous aperients and alcoholic stimulants to counteract symptoms of collapse are desirable. Friction, bandaging, and clothing to keep up the superficial circulation should be resorted to.
