Aphorism 31 to 40


In these aphorisms Hahnemann discusses why human body is more susceptible to the action of the similar medicine as compared to the natural disease. In later aphorisms he discusses what happens when two dissimilar diseases meet in the body….


§ 31

The inimical forces, partly psychical, partly physical, to which our terrestrial existence is exposed, which are termed morbific noxious agents, do not possess the power of morbidly deranging the health of man unconditionally1; but we are made ill by them only when our organism is sufficiently disposed and susceptible to attack of the morbific cause that may be present, and to be altered in its health, deranged and made to undergo abnormal sensations and functions – hence they do not produce disease in every one nor at all times.

1 When I call a disease a derangement of man’s state of health, I am far from wishing thereby to give a hyperphysical explanation of the internal nature of disease generally, or of any case of disease in particular. It is only intended by this expression to intimate, what it can be proved diseases are not and cannot be, that they are not mechanical or chemical alterations of material substance of the body, and not dependant on a material morbific substance, but that they are merely spirit-like (conceptual) dynamic derangements of the life.

§ 32

But it is quite otherwise with the artificial morbific agents which we term medicines. Every real medicine, namely, acts at all times, under all circumstances, on every living human being, and produces in him its peculiar symptoms (distinctly perceptible, if the dose be large enough), so that evidently every living human organism is liable to be affected, and, as it were, inoculated with the medicinal disease at all times, and absolutely (unconditionally), which, as before said, is by no means the case with the natural diseases.

§ 33

In accordance with this fact, it is undeniably shown by all experience1 that the living organism is much more disposed and has a greater liability to be acted on, and to have its health deranged by medicinal powers, than by morbific noxious agents and infectious miasms, or, in order words,  that the morbific noxious agents possess a power of morbidly deranging man’s health that is subordinate and conditional, often very conditional; whilst medicinal agents have an absolute unconditional power, greatly superior to the former.

1 A striking fact in corroboration of this is, that whilst previously to the year 1801, when the smooth scarlatina of Sydenham still occasionally prevailed epidemically among children, it attacked without exception all children who had escaped it in a former epidemic; in a similar epidemic which I witnessed in Konigslutter, on the contrary, all the children who took in time a very small dose of belladonna remained unaffected by this highly infectious infantile disease. If medicines can protect from a disease that is raging around, they must possess a vastly superior power of affecting our vital force.

§ 34 Fifth Edition

The greater strength of the artificial diseases producible by medicines is, however, not the sole cause of their power to cure natural disease. In order that they may effect a cure, it is before all things requisite that they should be capable of producing in the human body an artificial disease as similar as possible to the disease to be cured, in order, by means of this similarity, conjoined with its somewhat greater strength, to substitute themselves for the natural morbid affection, and thereby deprive the latter of all influence upon the vital force. This is so true, that no previously existing disease can be cured, even by Nature herself, by the accession of a new dissimilar disease, be it ever so strong, and just as little can it be cured by medical treatment with drugs which are incapable of producing a similar morbid condition in the healthy body.

§ 34 Sixth Edition

The greater strength of the artificial diseases producible by medicines is, however, not the sole cause of their power to cure natural disease. In order that they may effect a cure, it is before all things requisite that they should be capable of producing in the human body an artificial disease as similar as possible to the disease to be cured, which, with somewhat increased power, transforms to a very similar morbid state the instinctive life principle, which in itself is incapable of any reflection or act of memory. It not only obscures, but extinguishes and thereby annihilates the derangement caused by the natural disease. This is so true, that no previously existing disease can be cured, even by Nature herself, by the accession of a new dissimilar disease, be it ever so strong, and just as little can it be cured by medical treatment with drugs which are incapable of producing a similar morbid condition in the healthy body.

§ 35

In order to illustrate this, we shall consider in three different cases, as well what happens in nature when two dissimilar natural diseases meet to in one person, as also the result of the ordinary medical treatment of diseases with unsuitable allopathic drugs, which are incapable of producing an artificial morbid condition similar to the disease to be cured, whereby it will appear that even Nature herself is unable to remove a dissimilar disease already present by one that is unhomoeopathic, even though it be stronger, and just as little is the unhomoeopathic employment of even the strongest medicines ever capable of curing any disease whatsoever.

§ 36

I. If the two dissimilar diseases meeting together in the human being be of equal strength, or still more if the older one be the stronger, the new disease will be repelled by the old one from the body and not allowed to affect it. A patient suffering from a severe chronic disease will not be infected by a moderate autumnal dysentery or other epidemic disease. The plague of the Levant, according to Larry,1 does not break out where scurvy is prevalent, and persons suffering from eczema are not infected by it. Rachitis, Jenner alleges, prevents vaccination from taking effect. Those suffering from pulmonary consumption are not liable to be attacked by epidemic fevers of a not very violent character, according to Von Hildenbrand.

§ 37 Fifth Edition

So, also under ordinary medical treatment, an old chronic disease remains uncured and unaltered if it is treated according to the common allopathic method, that is to say, with medicines that are incapable of producing in healthy individuals a state of health similar to the disease, even though the treatment should last for years and is not of too violent character. This is daily witnessed in practice, it is therefore unnecessary to give any illustrative examples.

1 But if treated with violent allopathic remedies, other diseases will be formed in its place which are more difficult and dangerous to life.

§ 38

II. Or the new dissimilar disease is the stronger. In this case the disease under which the patient originally labored, being the weaker, will be kept back and suspended by the accession of the stronger one, until the latter shall have run its course or been cured, and then the old one reappears uncured. Two children affected with a kind of epilepsy remained free from epileptic attacks after infection with ringworm (tinea) but as soon as the eruption on the head was gone the epilepsy returned just as before, as Tulpius1 observed. The itch, as Schopf2 saw, disappeared on the occurrence of the scurvy, but after the cure of the latter it again broke out. So, also the pulmonary phthisis remained stationary when the patient was attacked by a violent typhus, but went on again after the latter had run its course.3 If mania occur in a consumptive patient, the phthisis with all its symptoms is removed by the former; but if that go off, the phthisis returns immediately and proves fatal.4 When measles and smallpox are prevalent at the same time, and both attack the same child, the measles that had already broken out is generally checked by the smallpox that came somewhat later; nor does the measles resume its course until after the cure of the smallpox; but it not infrequently happens that the inoculated smallpox is suspended for four days by the supervention of the measles, as observed by Manget,5 after the desquamation of which the smallpox completes its course. Even when the inoculation of the smallpox had taken effect for six days, and the measles then broke out, the inflammation of the inoculation remained stationary and the smallpox did not ensue until the measles had completed its regular course of seven days.6 In an epidemic of measles, that disease attacked many individuals on the fourth or fifth day after the inoculation of smallpox and prevented the development of the smallpox until it had completed its own course, whereupon the smallpox appeared and proceeded regularly to its termination.7 The true, smooth, erysipelatous-looking scarlatina of Sydenham, with sore throat, was checked on the fourth day by the eruption of cow-pox, which ran its regular course, and not till it was ended did the scarlatina again establish itself; but on another occasion, as both diseases seem to be of equal strength, the cow-pox was suspended on the eighth day by the supervention of the true, smooth scarlatina of Sydenham,8 and the red areola of the former disappeared until the scarlatina was gone, wherein the cow-pox immediately resumed its course, and went on its regular termination.9 The measles suspended the cow-pox; on the eighth day, when the cow-pox had nearly attained its climax, the measles broke out; the cow-pox now remained stationary, and did not resume and complete its course until the desquamation of the measles, had taken place, so that on the sixteenth day it presented the appearance it otherwise would have shown on the tenth day, as Kortum10 observed.

Samuel Hahnemann
Samuel Hahnemann (1755-1843) was the founder of Homoeopathy. He is called the Father of Experimental Pharmacology because he was the first physician to prepare medicines in a specialized way; proving them on healthy human beings, to determine how the medicines acted to cure diseases.

Hahnemann's three major publications chart the development of homeopathy. In the Organon of Medicine, we see the fundamentals laid out. Materia Medica Pura records the exact symptoms of the remedy provings. In his book, The Chronic Diseases, Their Peculiar Nature and Their Homoeopathic Cure, he showed us how natural diseases become chronic in nature when suppressed by improper treatment.
