Intermittent & Alternating Diseases

Organon Aphorism §243

In those often very pernicious intermittent fevers which attack a single person, not residing in a marshy district, we must also at first, as in the case of acute diseases generally, which they resemble in respect to their psoric origin, employ for some days, to render what service it may, a homoeopathic remedy selected for the special case from the other class of proved (not antipsoric) medicines; but if, notwithstanding this procedure, the recovery is deferred, we know that we have to do with psora on the point of its development, and that in this case antipsoric medicines alone can effect a radical cure.
