With regard to the intermittent fevers, 1 that prevail sporadically or epidemically (not those endemically located in marshy districts), we often find every paroxysm likewise composed of two opposite alternating states (cold, heat – heat, cold), more frequently still of three (cold, heat, sweat). Therefore the remedy selected for them from the general class of proved (common, not antipsoric) medicines must either (and remedies of this sort are the surest) be able likewise to produce in the healthy body two (or all three) similar alternating states, or else must correspond by similarity of symptoms, in the most homoeopathic manner possible, to the strongest, best marked, and most peculiar alternating state (either to the cold stage, or to the hot stage, or to the sweating state, each with its accessory symptoms, according as the one or other alternating state is the strongest and most peculiar); but the symptoms of the patient’s health during the intervals when he is free from fever must be the chief guide to the most appropriate homoeopathic remedy.2
1 The pathology hitherto in vogue, which is still in the stage of irrational infancy, recognizes but one single intermittent fever, which it likewise termed ague, and admits of no varieties but such as are constituted by the different intervals at which the paroxysms recur, quotidian, tertian, quartan etc. But there are much more important differences among them than what are marked by the periods of their recurrence; there are innumerable varieties of these fevers, some of which cannot even be denominated ague, as their fits consist solely of heat; others, again, are characterised by cold alone, with or without subsequent perspiration; yet others which exhibit general coldness of the surface, with a sensation on the patient’s part, or whilst the body feels externally hot, the patient feels cold; others, again, in which one paroxysm consists entirely of a rigor or simple chilliness followed by an interval of health, while the next consists of heat alone, followed or not by perspiration; others, again, in which the heat comes first and the cold stage not till that is gone; others, again, wherein after a cold or hot stage apyrexia ensues, and then perspiration comes on like a second fit, often many hours subsequently; others, again, in which no perspiration at all comes on, and yet others in which the whole attack consists of perspiration alone, without any cold or hot stage, or in which the perspiration is only present during the heat; and there are innumerable other differences, especially in regard to the accessory symptoms, such as headache of a peculiar kind, bad taste of the mouth, nausea, vomiting, diarrhoea, want of or excessive thirst, peculiar pains in the body or limbs, disturbed sleep, deliria, alterations of temper, spasms, etc., before, during or after the sweating stage, and countless other varieties. All these are manifestly intermittent fevers of very different kinds, each of which, as might naturally be supposed, requires a special (homoeopathic) treatment. It must be confessed that they can almost all be suppressed (as is often done) by enormous doses of bark and of its pharmaceutical preparation, the sulphate of quinine; that is to say, their periodical recurrence (their typus) may be extinguished by it, but the patients who suffered from intermittent fevers for which cinchona bark is not suitable, as is the case with all those epidemic intermittent fevers that traverse whole countries and even mountainous districts, are not restored to health by the extinction of the typus; on the contrary, they now remain ill in another manner, and worse, often much worse, than before; they are affected by peculiar, chronic bark dyscrasias, and can scarcely be restored to health even by a prolonged treatment by the true system of medicine – and yet that is what is called curing, forsooth!
2 Dr. von Bonninghausen, who has rendered more services to our beneficent system of medicine than any other of my disciples, has best elucidated this subject, which demands so much care, and has facilitated the choice of the efficient remedy for the various epidemics of fever, in his work entitled Versuch einer homoopathischen Therapie der Wechselfieber, 1833, Muster bi Regensberg.
