§ 236

§ 237

But if the stage of apyrexia be very short, as happens in some very bad fevers, or if it be disturbed by some of the after sufferings of the previous paroxysm, the dose of the homœopathic medicine should be administered when the perspiration begins to abate, or the other subsequent phenomena of the expiring paroxysm begin to diminish.

§ 238 Fifth Edition

It is only when the suitable medicine has with a single dose destroyed several fits and manifest health and ensued, but after some time indications of a new paroxysm appear, only then can and must the same medicine be given again, provided always the totality of the symptoms is still the same. This recurrence of the same fever after an interval of health is, however, only possible when the noxious influence that first excited the intermittent fever still continues to act upon the convalescent, as happens in marshy districts; in which case a permanent cure is often only possible by the removal of this exciting cause (as, for instance, a residence in a mountainous country if the case was one of marsh intermittent fever).
 

§ 238 Sixth Edition

Not infrequently, the suitable medicine has with a single dose destroyed several attacks and brought about the return of health, but in the majority of cases, another dose must be administered after such attack. Better still, however, when the character of the symptoms has not changed, doses of the same medicine given according to the newer discovery of repetition of doses (see note to § 270), may be given without difficulty in dynamizing each successive dose with 10-12 succussions of the vial containing the medicinal substance. Nevertheless, there are at times cases, though seldom, where the intermittent fever returns after several days’ well being. This return of the same fever after a healthy interval is only possible when the noxious principle that first caused the fever, is still acting upon the convalescent, as is the case in marshy regions. Here a permanent restoration can often take place only by getting away from this causative factor, as is possible by seeking a mountainous retreat, if the cause was a marshy fever.
commentary:

REPETITION OF MEDICINE IN INTERMITTENT FEVER .

Most of the time single dose of homoeopathic medicine that covers all the stage of the fever  is sufficient to bring back the health. But some times it may happen that it require second such dose after the attack. It may frequently happen that  the character of the symptoms has not changed, after administration of the first doses then  the same medicine can given according to the of repetition of doses (see note to § 270),  by dynamizing serial successive dose with 10-12 succussions of the vial containing the medicinal substance.

Maintaining cause of intermittent fever

The return of the same fever after a healthy interval is only possible when the noxious principle that first caused the fever, is still acting upon the convalescent, as is the case in marshy regions i.e. people  living in marshy places, the permanent cure in such diseases is only possible by removing this maintaining cause-like places of residence should be changed from marshy area to mountainous region.

§ 239

As almost every medicine causes in its pure action a special, peculiar fever and even a kind of intermittent fever with its alternating states, differing from all other fevers that are caused by other medicines, homœopathic remedies may be found in the extensive domain of medicines for all the numerous varieties of natural intermittent fevers and, for a great many of such fevers, even in the moderate collection of medicines already proved on the healthy individual.
commentary:

Almost all medicine causes in its pure action a special, peculiar fever and many can produce various alternating state of intermittent fever. Each medicine can produce alternating state which differ from other medicines, so that we can individualize each of the intermittent fever. So homœopathic remedies may be found in the broad domain of medicines for all the  varieties of natural intermittent fevers. A great many of such fevers, require only moderate collection of medicines already proved on the healthy individual.

§ 240

But if the remedy found to be the homœopathic specific for a prevalent epidemic of intermittent fever do not effect a perfect cure in some one or other patient, if it be not the influence of a marshy district that prevents the cure, it must always be the psoric miasm in the background, in which case antipsoric medicines must be employed until complete relief is obtained.
commentary:

§ 241

Epidemics of intermittent fever, in situations where none are endemic, are of the nature of chronic diseases, composed of single acute paroxysms; each single epidemic is of a peculiar, uniform character common to all the individuals attacked, and when this character is found in the totality of the symptoms common to all, it guides us to the discovery of the homœopathic (specific) remedy suitable for all the cases, which is almost universally serviceable in those patients who enjoyed tolerable health before the occurrence of the epidemic, that is to say, who were not chronic sufferers from developed psora.
