I have frequently treated this form of hemorrhage successfully by means of the perchloride of iron given internally; it has a direct local styptic effect, and in some aggravated cases, when the hemorrhage has occurred frequently, it has arrested it at the time, apparently prevented relapse, and certainly lessened after ill-effects, such as anaemia. In recent acute cases, ipecacuanha powder in doses of 1 or 2 gr. is more efficacious, but in semi-acute cases it is well to alternate this remedy (every half-hour to every two or three hours) with 15 to 30 min. of the iron tincture in water. I have known this method check severe hemorrhage in a case of gastric ulceration, after other remedies had failed, and Mr. Bowles records similar instances: he used 1 dr. of the tincture in 1 oz. of water, giving it after the stomach had been emptied by emesis, so that it could directly reach the bleeding part (British Medical Journal, i., 1872). Deleau, Pleischl, and others have also recorded excellent results from this treatment (Medical Times, i., 1857, Medico-Chirurgical Review, 1859), and it might with advantage be more generally adopted. Iron alum (a double sulphate of iron and ammonia) is also very valuable in this and other forms of internal hemorrhage (Lancet, i., 1871, p. 806).
