ARTICLE III.-Argentum-Nitricum. BY DR. PAZ ÁLVAREZ. "El Criterio Medico," March, 1870. Boerhave recommends the Nitrate of silver as a drastic in dropsies; Osborne in gastritis, with acid vomiting; Langdon Parker, as a sedative in gastric hyperæsthesia, acting similarly to Bismuth and Opium, Biggers and Steinetz in dyspepsia, and Hudson in inveterate gastralgias; it has also been used as a vermifuge; Trousseau and Pidoux employ it in injections in acute dysentery, in the diarrhoea of nursing children, when other remedies failed, with tormina and viscous sanguinolent stools and tenesmus, and drinking is accompanied by nausea and serous, green and lienteric stools; chronic diarrhoea of adults has also been benefited by it. In the acute period of whooping-cough during the convulsive stage, Berger saw benefit from it. Ricord and other practitioners praise it as a great antisyphiliticum. Hebra, of Vienna, contradicts emphatically the assertion, that large doses, employed for some length of time, produce a bluish tint of the skin. Everybody uses it as a caustic, as in small-pox, impetigo, or zona, or to prevent excessive granulations in ulcers, also in chronic indurations of the urethra, or of the tonsils, and in stenosis of the nasal organs, the external ear or the inferior part of the rectum, etc. Hahnemann, in his pathogenesis of silver, treats more of the pure metal, and to facilitate the study of the Nitrate of silver, we wish to compare them together, to find out as well their analogies as their differences. GENERAL SYMPTOMS.-Metallic silver produces anxiety, lassitude in the afternoon, weariness and weakness in the legs, with aversion to work, somnolence and sullen features, trembling of the extremities, sensation of distention in them and in the head, violent convulsions. The pains in the cartilages, periost. and bones, belonging to Silver are: a bruised sensation in the bones of the nose; a tearing, pulling pain on one side of the face; toothache, especially during mastication, or when anything cold or acid touches the teeth; pressure and weight in the chest; nocturnal tensive and compressive pains in the dorsal region; violent pains in the kidneys, as from luxation, in the morning, alleviated by walking; nocturnal osteocopic pains in the ulna; violent tearing, scraping pains in the knees; arthritic pains in the feet. The paralytic weakness in the lumbar region as far as the coxo-femoral articulation; the lassitude and tired sensation in the calves of the legs, as after a long march; the weariness and paralytic weakness of the lower extremities, belong also to the Nitrate of silver. The pulling cramps from the hip-joint to the knee, and from the hip-joint to the ankle, simulate a sciatica. The pains in the head have little analogy with those of the Metallic silver, as they arise undoubtedly from the bones of the cranium, whereas the latter are more of the congestive type; it has also semilateral prosopalgia, earache, and toothache simultaneously with the headache. It produces a gastralgia, that is a painful pressure in the stomach, analogue to the pressure in the cardia produced by the Argentum. The pressure and beating in the liver, and the pulsating pains in the spleen; the pressive, bruised sensation in the abdomen, as after ascites; the pains of excoriation and ulceration, and the spasmodic colic, are all found in the Nitrate of silver. We may therefore ascribe to the Nitrate the osteocopic pains, the paralytic weakness of the lumbar region and of the lower extremities, prosopalgia, otalgia, odontalgia, and sciatica. MORAL AND MENTAL SYMPTOMS.-The moral and intellectual state, which in the Metallic silver is hardly altered, manifests itself depressingly by anxiety, with sighing and profound discouragement, by apathy, with want of confidence in himself, with debility and nervous weakness; by exactness alternating with indifference; by hypochondria, and by looking at everything from the dark side, and by a presentiment of an epileptic attack. The intellectual faculties fall even to a degree of stupidity and incapacity of thinking, or to find the adequate words; dementia with foolish smiling, imbecile manners and visions, during which he closes his eyes in daytime, and confused sensations in the head, with painfulness, especially after taking coffee. HEAD. Obscuration of the sight, with anxiety, heat in the face and lachrymation-the head disturbed as if he would be attacked by an epileptic fit, dizziness and dulness, dizziness with languor, with passing headache, as if everything would turn in a circle, or with headache, nausea, blindness, and tearing in the ears. These vertigos, more numerous and pronounced than in the Metallic silver, united with the primary general symptoms, the spasms and sensation of strangulation in the throat, spasms in the oesophagus, with painful urging to expel eructations, pain in the stomach, nausea, languor, and accumulation of water in the mouth, and sensation of a lump ascending from the stomach, recommend this remedy in some hysterical epileptic attacks. The heaviness and painful fulness of the head, especially when awaking in the morning; the continual headache and the |
