Action, Medical Uses, and Dosage.—(See Hyoscyamus.) This tincture is sedative and soporific, and is frequently used in cases where opium does not agree, or where its constipating effects are not desired. Sometimes tincture of henbane purges; when this is the case, a small portion of laudanum may be added to it. The dose is from ½ to 1 fluid drachm.
