(* In a case where sepia had showed itself completely homoeopathically antipsoric for a peculiar headache that appeared in repeated attacks, and where the ailment had been diminished both as to intensity and duration, while the pauses between the attacks had also been much lengthened, when the attacks re-appeared I repeated the dose, which then caused the attacks to cease for one hundred days (consequently its action continued that long), when it reappeared to some degree, which necessitated another dose, after which no other attack took place for, now, seven years, while the health was also otherwise perfect.)
Whoever can restrain his impatience as to this point, will reach his object the more surely, and the more certainly. Only when the old symptoms, which had been eradicated or very much diminished by the last and the preceding medicines commence to rise again for a few days, or to be again perceptibly aggravated, then the time has most surely come when a dose of the medicine most homoeopathically fitting should be given. Experience and careful observation alone can decide; and it always has decided in my manifold, exact observations, so as to leave no doubt remaining.
Now if we consider the great changes which must be effected by the medicine in the many, variously composite and incredibly delicate parts of our living organism, before a chronic miasm so deeply inrooted and, as it were, parasitically interwoven with the economy of our life as psora is, can be eradicated and health be thus restored: then it may well be seen how natural it is, that during the long-continued action of a dose of antipsoric medicine selected homoeopathically, assaults may be made by it at various periods on the organism, as it were in undulating fluctuations during this long-continued disease. Experience shows that when for several days there has been an improvement, half hours or whole hours or several hours will again appear when the case seems to become worse; but these periods, so long as only the original ailments are renewed and no new, severe symptoms present themselves, only show a continuing improvement, being homoeopathic aggravations which do not hinder but advance the cure, as they are only renewed beneficent assaults on the disease, though they are wont to appear at times sixteen, twenty or twenty-four days after taking a dose of antipsoric medicine.
(These attacks, however, if the antipsoric remedy was selected fittingly and homoeopathically and the dose was a moderate one, during its continued action take place, ever more and more rarely and more feebly, but if the doses were too strong they come more frequently and more strongly, to the detriment of the patient.)
As a rule, therefore, the antipsoric medicine in chronic diseases continue their action the longer, the more tedious the diseases are. But vice versa also those medicines which in the healthy body show a long period of action act only a short time and quickly in acute diseases which speedily run their course (e.g. belladonna, sulphur, arsenic, etc.) and their periods of action are shorter, the more acute the diseases. The physician must, therefore, in chronic diseases, allow all antipsoric remedies to act thirty, forty or even fifty and more days by themselves, so long as they continue to improve the diseased state perceptibly to the acute observer, even though gradually; for so long the good effects continue with the indicated doses and these must not be disturbed and checked by any new remedy.*
(* The importance of avoiding the above-described two errors will hardly be realized by physicians. These great, pure truths will be questioned yet for years even by most of the homoeopathic physicians, and will not, therefore, be practiced, on account of the theoretical reflection and the reigning thought: It requires quite an effort to believe that so little a thing, so prodigiously small a dose of medicine, could effect the least thing in the human body, especially in coping with such enormously great, tedious diseases; but that the physician must cease to reason, if he should believe that these prodigiously small doses can act not only two or three days, but even twenty, thirty and forty days and longer yet, and cause, even to the last day of their operation, important, beneficent effects otherwise unattainable. Nevertheless this true theorem is not to be reckoned among those which should be comprehended, nor among those for which I ask a blind faith. I demand no faith at all, and do not demand that anybody should comprehend it. Neither do I comprehend it; it is enough, that it is a fact and nothing else. Experience alone declares it, and I believe more in experience than in my own intelligence. But who will arrogate to himself the power of weighing the invisible forces that have hitherto been concealed in the inner bosom of nature, when they are brought out of the crude state of apparently dead matter through a new, hitherto undiscovered agency, such as is potentizing by long continued trituration and succussion. But he who will not allow himself to be convinced of this and who will not, therefore, imitate what I now teach after many years’ trial and experience (and what does the physician risk, if he imitates it exactly?), he who is not willing to imitate it exactly, can leave this greatest problem of our art unsolved, he can also leave the most important chronic diseases uncured, as they have remained unhealed; indeed, up to the time of my teaching. I have no more to say about this. It seemed to me my duty to publish the great truths to the world that needs them, untroubled as to whether people can compel themselves to follow them exactly or not. If it is not done with exactness, let no one boast to have imitated me, nor expect a good result.
