Action And Uses

This powerful substance closely resembles in its action the nitrites of amyl and soda; its activity being apparently due to nitrous acid formed by its decomposition within the body. It is used for the same class of cases, such as angina pectoris, chronic heart disease, sea-sickness, and asthma and other spasmodic disorders.
