Characteristics.-Kali bichromicum (with the other Chromium preparations, Chro. ac. and Chro. ox.) owes its introduction into the homoeopathic materia medica to the late Dr. J. J. Drysdale, whose monograph upon it, forming one section of the Hahnemann Materia Medica, and now occupying pp. 457 to 573 of Materia Medica Physiological and Applied, is the most complete account of the remedy which we possess. The Bichromate of Potash, which is manufactured in large quantities from chrome-iron-ore, is the preparation from which all other salts of Chromium are derived. The native association of Chromium with Ferrum is worthy of note. The Bichromate is largely used in the arts in dying, calico-printing, wood-staining, in photography, and as a solution for producing the current in electric batteries. Many of the most remarkable symptoms were obtained from workmen engaged in the preparation of the salt. Some of these had been noted before Drysdale took up the study of the drug. The first proving was published by him in 1844 in the British Journal of Homoeopathy. The following year it was proved by the Austrian Society. The effects of the drug show profound action on the entire organism, and characteristic features of the utmost value to the prescriber have been brought out, rendering the drug one of the most important members of the homoeopathic materia medica. Among these keynotes of Kali bi. four may be named as pre-eminent: (1) Discharges from mucous membranes of tough, stringy mucus, or muco-pus, which adheres to the part and can be drawn out in strings. (2) The occurrence of pain in small spots. In connection with this is another feature showing a sharply defined action: (3) Punched-out, perforating ulcers, occurring on skin, mucous membranes, and affecting bones (e.g. vomer, palate). (4) Alternating and shifting conditions: pains wander from part to part; rheumatic pains alternate with gastric symptoms, or with dysentery; headache alternates with blindness; fibrinous deposits extend downwards. Among other leading characters, scarcely less distinctive are: (a) The formation of plugs or clinkers on mucous membranes, especially in the nose. (This may be regarded as an advanced stage of the stringy mucous secretions.) (b) Still another Variety of this is the formation of false membranes as in croup and diphtheria, with hoarse, metallic cough; and the formation of casts of the bronchial tubes in fibrinous bronchitis. (c) Yet another characteristic mucous discharge is one of "jelly-like mucus." (d) Indigestion from drinking beer; loss of appetite; weight in pit of stomach immediately after eating; flatulence. (e) Among peculiar sensations the "hair sensation" is marked in Kali bi. It occurs chiefly on the back part of the tongue and in the left nostril.-It can hardly be questioned that Chromium is the predominant partner in the action of this salt, but it would be wrong to consider the Kali element as of no account, and it would be still more wrong to disregard the very large proportion of oxygen. It is as an oxydising agent and disinfectant that K. bi. is chiefly known in general medicine, and it is probably to the oxygen element that the ulcerating properties of the drug are largely due. One of its effects is "odourless stools," and the oxygen element is probably accountable for this. Another point in this connection is that the antidotes to poisonous doses of Kali bi. are the same as the antidotes to the acids. The Kali parallels must be sought chiefly in Causticum and Kali carb. The general resemblance is great, but the minute correspondences are not very striking. One possible point of correspondence has been pointed out. Storer (Med. Adv., xxv. 98), cured with Kali bi. a case of asthma in a man who noticed that the attacks were caused by and always followed coitus. The Kali bi. was prescribed on other indications, but this symptom must be noted for future verification. Kali c. has marked "< from coitus," and also from emissions; and Caust. has stupid feeling in the head the day after an emission." Caust. has many symptoms of disordered vision; though it has not the "blindness followed by headache, the sight improving as the pain becomes worse" of Kali bi. This is very characteristic and has led me to many cures. Both Caust. and Kali bi. have many symptoms of ulceration internal and external. Nash relates a good cure with Kali bi. A woman had deep punched-out ulcers with regular edges. One of them had perforated the soft palate and threatened the whole palate. It had a syphilitic appearance, and the patient had been long under old-school treatment. There was also a stringy discharge, but not to a great amount. In three weeks Kali bi. 30 made a cure which proved permanent; the local condition entirely healed and the patient's general state improved correspondingly. Apropos of syphilis Drysdale quotes a long series of cases of syphilis in all stages treated by J. E. GÃ¼ntz with "Chrome water." This consists of an artificial aerated water containing in 600 grammes of water Kali bi. 0.03 grms., Kali nit. 0.1 grm., Natr. nit., 0.1 grm., Nat. mur., 0.2 grm.; this mixture is incorporated with carbonic acid under the highest pressure, at low temperature, and kept some time before use. The dose given was from half to two bottles daily (each bottle containing 600 grammes) in five doses, given on a full stomach. Even in this dilution the mixture was sufficiently disgusting in taste, and to some quite intolerable. A number of the Kali bi. symptoms were produced, but on the whole very notable and evidently specific curative action was observed. Out of 100 cases of primary syphilis 64 remained without constitutional symptoms. In secondary and tertiary syphilis "chromo-water" was also remarkably successful. In strictly homoeopathic practice Kali bi. has been no less successful, as its symptoms correspond to a great variety of the manifestations of that disease, especially keratitis and iritis, ozaena, bone-pains and nodes, sore throat, syphilitic rheumatism and ulcers.
