back Argentum Nitricum

Nitrate of Silver.

Preparation. - The pure salt is dissolved in distilled water, one part by weight to nine parts by weight of water. The first three decimal dilutions are made with distilled water, the 4x with dilute alcohol, and subsequent dilu- tions with alcohol. Dilutions should be made fresh when used.

The most important action of Argentum Nitricum is on the blood, producing an antiplastic effect, rendering it more fluid and darker ; the red corpuscles lose their coloring matter ; the blood stagnates in the vessels causing ecchymosis, and nutrition is interfered with. The flow of bile is increased, and degenerative congestion in the liver is produced, and albumi- nuria. As a result of defective nutrition the bones and perios- teum are involved. The drug also acts as a highly irritant poison, affecting primarily the mucous membranes of the eyes, mouth, throat, and upper air-passages, the bowels and urethra, causing violent congestion, and destructive inflammation and ulcerations of these tracts. The nervous system is also decidedly affected, giving rise to great prostration, and causing violent tetanic convulsions, followed by paralysis.

THERAPEUTICS. The chief therapeutic value of Argentum Nitricum is in the treatment of catarrhal affections of mucous membranes characterized by a profuse muco-purulent discharge (Puls.).  Especially useful in purulent ophthalmia-acute granular conjunctivitis, with profuse discharge, great redness, swelling and even ulceration, the cornea being involved.  An excellent remedy in the purulent ophthalmia of new born infants.  Useful in ciliary blepharitis (see symptom), though in chronic cases with much thickening of the edge of the lids Arg. met. is more frequently used.  Paralysis of accommodation from errors of refraction; glasses failing.  Nasal catarrh, with loss of smell and haemorrhages.  Acute and chronic pharyngitis, uvula and fauces dark red, thick, tenacious mucus, rawness and soreness, sensation of a splinter, etc.  Catarrh of smokers, with sensation of a hair causing cough, better again by smoking.

In the chronic laryngitis of singers it is an excellent remedy, though less often indicated than Arg. met. Threatening paralysis of the lungs. Asthma. Angina pectoris.  Argentum Nitricum has proved useful in various chronic affections of the brain and nervous system.  Melancholia; spinal irritation; epilepsy and epileptiform convulsions; paralysis, paraplegia; functional paralysis following acute diseases, post diphtheritic, etc.; prosopalgia; cardialgia; gastralgia; nephralgia; locomotor ataxia.  According to Allen it is a valuable remedy in the mental depression or irritability which results from brainfag, with general debility and trembling of the whole body.  Has been used in septic forms of scarlet fever.  In bone affections, especially caries of small bones.  In chlorosis.
