Organon aphorism §231
The INTERMITTENT DISEASES deserve a special consideration, as well those that recur at certain periods—like the great number of intermittent fevers, and the apparently non-febrile affections that recur at intervals like intermittent fevers—as also those in which certain morbid states alternate at uncertain intervals with morbid states of a different kind.
Organon aphorism §232
These latter, ALTERNATING diseases, are also very numerous,( 127 ) but all belong to the class of chronic diseases; they are generally a manifestation of developed psora alone, sometimes, but seldom, complicated with a syphilitic miasm, and therefore in the former case may be cured by antipsoric medicines; in the latter, however, in alternation with antisyphilitics as taught in my work on the CHRONIC DISEASES.
Organon aphorism §233
The TYPICAL INTERMITTENT DISEASES are those where a morbid state of unvarying character returns at a tolerably fixed period, whilst the patient is apparently in good health, and takes its departure at an equally fixed period; this is observed in those apparently non-febrile morbid STATES THAT COME and go in a periodical manner (at certain times), as well as in those of a febrile character, to wit, the numerous varieties of intermittent fevers.
Organon aphorism §234
Those apparently non-febrile, typical, periodically recurring morbid states just alluded to observed in one single patient at a time (they do not usually appear sporadically or epidemically) always belong to the chronic diseases, mostly to those that are purely psoric, are but seldom complicated with syphilis, and are successfully treated by the same means; yet it is sometimes necessary to employ as an intermediate remedy a small dose of a potentized solution of cinchona bark, in order to extinguish completely their intermittent type.
Organon aphorism §235
With regard to the INTERMITTENT FEVERS, ( 128 ) 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 homeopathic 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 stage, 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 homeopathic remedy.
