    AMMOJSTOE carbonas. 49 any of its preparations, produces warmth at the epigastrium, and acts as an antacid ; increases the force and frequency of the pulse, allays spasm, and promotes the secretions from the skin and mucous membranes, especially the bronchial. In larger doses throbbing and pain in the head, with heaviness, are induced ; and in still larger medicinal doses, emetic effects ; beyond this poison- ous irritant symptoms may be caused. The action of ammonia differs much from that of alcohol, probably influencing the ganglionic and spinal systems rather than the brain proper, and increasing the functions of the secreting and excreting organs. It does not render the urine alkaline, but perhaps a portion ap- pears in that fluid as nitric acid. Externally applied, ammonia is rubefacient, and even vesicant. Ammonia is given to rouse the system in syncope ; to diminish spasm in hysteria ; to relieve nervous headache, the after-effects of alcohol, and delirium tremens ; also as a stimulant in low states of the system, as typhoid forms of fever ; in pneumonia and bron- chitis, in which the expectorant power is also useful ; as a stimulant and antacid in low forms of dyspepsia connected with increased secretion of acid and flatulence in the stomach. Externally it is applied to the mucous membrane of the nose in syncope and insensibility (in such cases care should be taken not to use too strong solutions) ; occasionally also it is inhaled very much diluted, as an expectorant in chronic bronchitis. On the skin it is used, combined with volatile or essential oils, in most cases where a counter-irritant effect is desired to be produced by means of an embrocation, as over painful parts, stiff joints, &c.
