If, however, in such an epidemic intermittent fever the first paroxysms have been left uncured, or if the patients have been weakened by improper allopathic treatment; then the inherent psora that exists, alas! is so many persons, although in a latent state, becomes developed, takes on the type of the intermittent fever, and to all appearances continues to play the part of the epidemic intermittent fever, so that the medicine, which would have been useful in the first paroxysms (rarely an antipsoric), is now no longer suitable and cannot be of any service. We have now to do with a psoric intermittent fever only, and this will generally be subdued by minute and rarely repeated doses of sulphur or hepar sulphuris in a high potency.

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.

Having thus seen what attention should, in the homoeopathic treatment, be paid to the chief varieties of disease and to the peculiar circumstance connected with them, we now pass on to what we have to say respecting the remedies and the mode of employing them, together, with the regimen to be observed during their use.

Every perceptibly progressive and strikingly increasing amelioration during treatment is a condition which, as long as it lasts, completely precludes every repetition of the administration of any medicine whatsoever, because all the good the medicine taken continues to effect is now hastening towards its completion. This is not infrequently the case in acute diseases, but in more chronic diseases, on the other hand, a single doses an appropriately selected homoeopathic remedy will at times complete even with but slowly progressive improvement and give the help which such a remedy in such a case can accomplish naturally within 40, 50, 60, 100, days. This is, however, but rarely the case; and besides, it must be a matter of great importance to the physician as well as to the patient that were it possible, this period should be diminished to one-half, one-quarter, and even still less, so that a much more rapid cure might be obtained. And this may be very happily effected, as recent and oft-repeated observations have taught me under the following conditions; firstly, if the medicine selected with the utmost care was perfectly homoeopathic ; secondly, if it is highly potentized, dissolved in water and given in proper small dose that experience has taught as the most suitable in definite intervals for the quickest accomplishment of the cure but with the precaution, that the degree of every dose deviate somewhat from the preceding and following in order that the vital principle which is to be altered to a similar medicinal disease be not aroused to untoward reactions and revolt as is always the case with unmodified and especially rapidly repeated doses.

For this purpose, we potentize anew the medicinal solution (with perhaps 8, 10, 12 succussions) from which we give the patient one or (increasingly) several teaspoonful doses, in long lasting diseases daily or every second day, in acute diseases every two to six hours and in very urgent cases every hour or oftener. Thus in chronic diseases, every correctly chosen homoeopathic medicine, even those whose action is of long duration, may be repeated daily for months with ever increasing success. If the solution is used up (in seven to fifteen days) it is necessary to add to the next solution of the same medicine if still indicated one or (though rarely) several pellets of a higher potency with which we continue so long as the patient experiences continued improvement without encountering one or another complaint that he never had before in his life. For if this happens, if the balance of the disease appears in a group of altered symptoms then another , one more homoeopathically related medicine must be chosen in place of the last and administered in the same repeated doses, mindful, however, of modifying the solution of every dose with thorough vigorous succussions, thus changing its degree of potency and increasing it somewhat . On the other hand, should there appear during almost daily repetition of the well indicated homoeopathic remedy, towards the end of the treatment of a chronic disease, so-called (Aphorism 161) homoeopathic aggravations by which the balance of the morbid symptoms seem to again increase somewhat (the medicinal disease, similar to the original, now alone persistently manifests itself). The doses in that case must then be reduced still further and repeated in longer intervals and possibly stopped several days, in order to see if the convalescence need no further medicinal aid. The apparent symptoms (Schein-Symptom) caused by the excess of the homoeopathic medicine will soon disappear and leave undisturbed health in its wake. If only a small vial say a dram of dilute alcohol is used in the treatment , in which is contained and dissolved through succussion one globule of the medicine which is to be used by olfaction every two, three or four days, this also must be thoroughly succussed eight to ten times before each olfaction.

When, to the observant practitioner who accurately investigates the state of the disease, it is evident, in urgent cases after the lapse of only six, eight or twelve hours that he has made a bad selection in the medicine last given, in that the patient's state is growing perceptibly, however slightly, worse from hour to hour, by the occurrence of new symptoms and sufferings, it is not only allowable for him, but it is his duty to remedy his mistake, by the selection and administration of a homoeopathic medicine not merely tolerably suitable, but the most appropriate possible for the existing state of the disease (Aphorism167).
