Action and Therapy.—Lupulin is administered in disorders for which infusion and tincture of hops were formerly given. It is a remedy for nervousness, to allay irritation and to produce sleep. It gives a sense of mental tranquillity which makes it a valuable agent in nervous unrest due to nocturnal seminal emissions, and relieves irritation of the genital tract when associated with the latter. It relieves irritation of the bladder, with frequent urination, and is quite efficient in chordee. When delirium tremens is accompanied by cerebral hyperemia it is of considerable service. Insomnia due to nervous debility or to worry, or headache associated with active cerebral circulation, is benefited by lupulin; while for painful conditions it may be employed when they depend upon nervous debility. For the latter reason it has been given with success in dysmenorrhea, and other painful conditions of the uterus and in after-pains. Lupulin checks fermentative changes in the stomach, thus proving useful in yeasty indigestion with acid eructations and dilation of the stomach, and in the headache due to such gastric disturbance.
