Action, Medical Uses, and Dosage.—This forms a powerful sedative narcotic, which has been used in neuralgia, cholera, and other symptoms where the India hemp has been recommended, with much success. The dose is 5 drops, gradually increased to 20 or 40, according to its influence. The extract and fluid extract are, however, more frequently employed than the simple tincture.
