Potassium, Acetate. Diuretic, refrigerant, alterative. Used in dropsy, gout, and rheumatism in 30 gr. doses. Bicarbonate, antacid, antilithic, and diuretic in 4 to 5 gr. doses. It is a valuable salt. Bichromate. See Dichromate. Bitartrate, "Cream of Tartar," aperient in 2 to 3 3 doses and diuretic in 30 gr. closes. Bromide. This important drug will not be discussed in detail here. Personally, I do not believe it can be of any permanent use, and may be very harmful in diseases produced or accompanied by organic lesions or nutritive changes. Its unwise use has done a vast deal of harm in epilepsy. We should not forget that brominism is manifested by a general failure of the mental powers. anesthesia of the mucous membranes, partial paralysis of a peculiar nature, acne, loss of sexual power, and weakened heart.
In large doses (20 to 40 gr.) it is employed in great nervous excitement following nervous strain, sleeplessness, and delirium, nightmare (according to age), mania, some cases of epilepsy (with caution), chorea, and tetanus. In strychnia poisoning single doses of 60 gr. may be given. In moderate doses (10 to 20 gr., usually IS gr.) in sleeplessness from exhaustion, migraine from irritable nerves, neuralgia from same cause, palpitation at climacteric, seminal emissions, nymphomania, and priapism. In small doses (I to 3 gr.) in infantile wakefulness, colic, convulsions from tooth or bowel irritation, and in whooping cough. In adults, give small doses for acne occurring at puberty or menstrual periods. The homeopathic use in minute doses is absolutely useless and a waste of time. Carbonate, in I5 gr. doses, is antacid, antilithic, and cholagogue, of value in acid dyspepsia, jaundice, etc. The IX trituration taken for long periods is asserted to be of value in hip-joint disease, anemia with constant backache in young girls, and ulcerative pulmonary phthisis. Chlorate, alterative, antiseptic, antisialagogue, employed now principally in mercurial salivation in doses of 3 or 4 gr. Internally, it is apt to cause inflammation of the kidneys, and its general use is almost abandoned. Externally, in 3 to 5% solution in ulcerated states, particularly in mouth and throat. Citrate, diaphoretic and refrigerant in I5 gr. doses. Cyanide. This is an antispasmodic and sedative that markedly depresses the heart. The U. S. P. has unwisely incorporated it. We have already in use altogether too many dangerous cough sedatives. It is suggested in 1-6 gr. doses in certain mental diseases, angina pectoris, etc. We have borrowed it from the homeopaths, who use 1-100 to 1-20 gr. doses in aggravated neuralgias in temporal, orbital. and supramaxillary regions, and the agonizing pain of cancer of the tongue. In my opinion, its only safe use is in removing silver nitrate stains (I % solution), although in desperate pain we may properly use it as a last resort. Its use in whooping cough is exceedingly dangerous in all cases. Dichromate (or bichromate). I do not know who has played a practical joke upon the regular writers in having them assign this agent to the list of internal remedies under the classical homeopathic indications of long, long ago. However, he did a good thing, but a Ix or a 2X triturate is strong enough, and 1-5 gr. doses are hardly required and are apt to lead to gastric irritation. Both our recently revised materia medicas and the old homeopathic ones recommend it in aphonia, due to catarrh, with viscid mucus, chronic coryza, gastric ulcer, syphilis, and syphilitic ulcers and vegetations. In order to get a good working idea of the mental processes involved, read a homeopathic materia medica in comparison with the "made in Germany" therapeutics of today. It is exceedingly easy to "discover" new therapeutics when it is already worked out and presented in symptomatic indications rather than in a nosologic classification in literature with which the regular profession are not familiar. It would not be at all hard to prognosticate a whole list of future "made in Germany" ideas from homeopathic literature, and the coming "ethical proprietary" pharmaceutics from eclectic formulae not yet scooped up. Ferrocyanide, 70 gr. doses, in phthisical night-sweats. Hydroxide, escharotic in gangrene and warty excrescences. Used very unwisely internally in 1/4 to I gr. doses, well diluted. Hypophosphite, a valuable nerve tonic reconstructive, in 5 to 20 gr. doses. Iodide, in large doses, a most valuable alterative if discreetly used. It should not be given when there is irritation of the gastro-enteric or renal membranes. It is indicated in blood dyscrasias, chronic glandular inflammations, and in indurations. Naturally, this covers a whole class of diseases too well known to demand discussion here. In small doses (1/4 to I gr.) useful in catarrhal pain in frontal sinus, catarrhal neuralgia of face with acrid nasal discharges, lachrymation with injected conjunctiva, raw feeling in larynx with greenish expectoration, descending colds, and in pneumonia when hepatization commences. (Iodide of ammonia when desired to combine with ammon. carb.) Very small doses (I - 10 gr.) sometimes effective. Muriate ("Kali Muriaticum" of homeopathy) is used in 3x trituration in catarrhal affections, subacute inflammations, fibrinous exudations, and glandular swellings. Nitrate, a diuretic refrigerant in 5 to 30 gr. doses. Doses of 0 to I gr. are sometimes used in suppurative nephritis. Permanganate, an emmenagogue in I gr. dose in pill. A valuable antidote for morphia. As a wash in throat troubles (diphtheria, etc.), 5%. In general surgery as an antiseptic wash (10 to 20 gr. to I pint water). When applied to mucous membranes, only enough to cause slight reaction. Better commence with only enough to give a carmine pink tint to the water, and run up as case demands. Potassium and Sodium tartrate, or "Rochelle Salt," saline, cathartic, refrigerant. Average dose, 2 3. Sulphate in doses of 2 to 4 3 is actively cathartic, while 30 gr. is diuretic and aperient. It is also classed as antigalactic. Doses of I or 2 gr. are suggested in oxaluria.
