Intermittent & Alternating Diseases

Organon Aphorism §244

The intermittent fevers endemic in marshy districts and tracts of country frequently exposed to inundations, give a great deal of work to physicians of the old school, and yet a healthy man may in his youth become habituated even to marshy districts and remain in good health, provided he preserves a faultless regimen and his system is not lowered by want, fatigue or pernicious passions. The intermittent fevers endemic there would at the most only attack him on his first arrival; but one or two very small doses of a highly potentized solution of cinchona bark would, conjointly with the well-regulated mode of living just alluded to, speedily free him from the disease. But persons who, while taking sufficient corporeal exercise and pursuing a healthy system of intellectual occupations and bodily regimen, cannot be cured of marsh intermittent fever by one or a few of such small doses of cinchona – in such persons psora, striving to develop itself, always lies at the root of their malady, and their intermittent fever cannot be cured in the marshy district without antipsoric treatment. It sometimes happens that when these patients exchange, without delay, the marshy district for one that is dry and mountainous, recovery apparently ensues (the fever leaves them) if they be not yet deeply sunk in disease, that is to say, if the psora was not completely developed in them and can consequently return to its latent state; but they will never regain perfect health without antipsoric treatment.
