(Alkaloid from Decomposition of Morphine by Hydrochloric Acid)

The chief power of this drug lies in the speedy and effective vomiting that it produces, which becomes a strong guiding symptom to its homeopathic use. The vomiting is preceded by nausea, lassitude and increased secretion of sweat, saliva, mucus and tears. Pneumonia with vomiting. Combined alcoholism, with constant nausea, constipation, insomnia.

Head and Stomach
Vertigo. Dilated pupils. Nausea and vomiting. Violent inclination to vomit. Hot feeling all over body, especially head. Empty retching and headache; heartburn; pain between shoulder-blades. Reflex vomiting-pregnancy. Seasickness.

Non-homeopathic Uses
The hypodermic injection of one-sixteenth of a grain will cause full emesis within five to fifteen minutes in an adult without developing any other direct action apparently. Do not use in opium poisoning. Apomorph hypodermically, one-thirtieth grain or less, acts as a safe and sure hypnotic. Acts well even in delirium. Sleep comes on in half an hour.

Third to sixth potency.
