Intermittent & Alternating Diseases

Organon Aphorism §235

With regard to the intermittent fevers, 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.
