Let it be granted now, what cannot be doubted, that no diseases – if they do not result from the introduction of perfectly indigestible or otherwise injurious substances into the stomach, or into other orifices or cavities of the body, or from foreign bodies penetrating. the skin, etc. – that no disease, in a word, is caused by any material substance, but that every one is only and always a peculiar, virtual, dynamic derangement of the health; how injudicious, in that case, must not a method of treatment directed towards the expulsion14 of that imaginary material substance appear to every rational man, since no good, but only monstrous harm, can result from its employment in the principal diseases of mankind, namely, those of a chronic character!

14. There is a semblance of necessity in the expulsion by purgatives of worms, in so-called vermicular diseases. But even this semblance is false. A few lumbric; may be found in some children; in many there exist ascarides. But the presence of these is always dependent on a general taint of the constitution (the psoric), joined to an unhealthy mode of living. Let the latter be improved, and the former cured homÏopathically, which is most easily effected at this age, and none of the worms remain, and children cured in this manner are never troubled with them more; whereas after mere purgatives, even when combined with cina seeds, they soon reappear in quantities.

“But the tapeworm”, methinks I hear some one exclaim, “every effort should be made to expel that monster, which was created for the torment of mankind”.

Yes, sometimes it is expelled; but at the cost ot what after-sufferings, and with what danger to life! I should not like to have on my conscience the deaths of so many hundreds of human beings as have fallen sacrifices to the horribly violent purgatives, directed against the tapeworm, or the many years of indisposition of those who have escaped being purged to death. And how often does it happen that after all this health-and-life-destroying purgative treatment, frequently continued for several years, the animal is not expelled, or if so, that it is again produced!

What if there is not the slightest necessity for all these violent, cruel, and dangerous efforts to expel and kill the wormThe various species of tapeworm are only found along with the psoric taint, and always disappear when that is cured. But even before the cure is accomplished, they live – the patient enjoying tolerable health the while – not exactly in the intestines, but in the residue of the food, the excrement of the bowels, as in their proper element, quite quietly, and without causing the least disturbance, and find in the excrement what suffices for their nourishment; they then do not touch the walls of the intestine, and are perfectly harmless. But if the patient happens to be affected with an acute disease of any kind, then the contents of the bowels become intolerable to the animal; it twists about, comes in contact with, and irritates the sensitive walls of the intestines, causing a peculiar kind of spasmodic colic, which increases materially the sufferings of the patient. (So also the foetus in the womb becomes restless, turns about and kicks, only when the mother is ill; but when she is well; it swims quiet in its proper fluid without causing her any suffering.)

It is worthy of remark, that the morbid symptoms of patients suffering from tapeworm are generally of such a kind, that they are rapidly relieved (homÏopathically) by the smallest dose of tincture of male-fern root;* so that the ill-health of the patient, which causes this parasitic animal to be restless, is thereby for the time removed; the tapeworm then feels at ease, and lives on quietly in the excrement of the bowels, without particularly distressing the patient or his intestines, until the antipsoric treatment is so far advanced that the worm, after the eradication of the psora, finds the contents of the bowels no longer suitable for its support, and therefore spontaneously disappears, for ever from the now cured patient, without the least purgative medicine.

In short, the degenerated substances and impurities that appear in diseases are, undeniably, nothing more than products of the disease of the abnormally deranged organism, which are expelled by the latter, often violently enough – often much too violently – without requiring the aid of the evacuating art, and fresh products are always developed as long as it labors under that disease. These matters the true physician regards as actual symptoms of the disease, and they aid him to discover the nature of the disease, and to form an accurate portrait of it, so as to enable him to cure it with a similar medicinal morbific agent.

But the more modern adherents of the old school do not wish it to be supposed, that in their treatment they aim at the expulsion of material morbific substances. They allege that their multifarious evacuant processes are a mode of treatment by derivation, wherein they follow the example of nature which, in her efforts to assist the diseased organism, resolves fever by perspiration and diuresis pleurisy by epistaxis, sweat and mucous expectoration – other diseases by vomiting, diarrhaea and bleeding from the anus, articular pains by suppurating ulcers on the legs, cynanche tonsillaris by salivation, etc., or removes them by metastases and abscesses which she develops in parts at a distance from the seat of the disease.

Hence they thought the best thing to do was to imitate nature, by also going to work in the treatment of most diseases in a circuitous manner like the diseased vital force when left to itself and thus in an indirect manner,15 by means of stronger heterogeneous irritants applied to organs remote from the seat of disease, and totally dissimilar to the affected tissues, they produce evacuations, and generally kept them up, in order to draw, as it were, the disease thither.

15. In place of extinguishing the disease rapidly, without exhaustion of the strength and without going about the bush, with homogeneous, dynamic medicinal agents acting directly on the diseased points of the organism, as homÏopathy does.

This derivation, as it is called, was and continues to be one of the principal modes of treatment of the old
school of medicine.

In this imitation of the self-aiding operation of nature, as some call it, they endeavored to excite, by force, new symptoms in the tissues that are least diseased and best able to bear the medicinal disease, which should draw away16 the primary disease under the semblance of crises and under the form of excretions, in order to admit of a gradual lysis by the curative powers of nature.17

16. Just as if anything immaterial could be drawn away! So that here too was the notion of a substance and a morbific matter, excessively subtile though it might be supposed to be!

17. It is only the slighter and acute diseases that tend, when the natural period of their course has expired, to terminate quietly in resolution, as it is called, with or without the employment of not very aggressive allopathic remedies; the vital force, having regained its powers, then gradually substitutes the normal condition for the derangement of the health that has now ceased to exist. But in severe acute and in chronic diseases which constitute by far the greater portion of all human ailments, crude nature and the old school are equally powerless; in these, neither the vital force, with its self-aiding faculty, nor allopathy in imitation of it, can affect a lysis, but at the most a mere temporary truce, during which the enemy fortifies himself, in order, sooner or later, to recommence the attack with still greater violence.

This they accomplished by means of diaphoretic and diuretic remedies, blood-lettings, setons and issues, but chiefly by irritant drugs to cause evacuation of the alimentary canal, sometimes upwards by means of emetics, sometimes (and this was the favorite plan) downwards by means of purgatives, which were termed aperient and dissolvent18 remedies.

18. An expression which likewise betrays that they imagined and presupposed a morbific substance, which had to be dissolved and expelled.

To assist this derivative method they employed the allied treatment by counter-irritants; woolen garments to the bare skin, foot-baths, nauseants, inflicting on the stomach and bowels the pangs of hunger (the hunger-treatment), substances to cause pain, inflammation, and suppuration in near or distant parts as the application of horseradish, mustard plasters, cantharides, blisters, mezereum setons, issues, tartar-emetic ointment, moxa, actual cautery, acupuncture, etc.; here also following the example of crude unassisted nature, which endeavors to free herself from the dynamic disease (in the case of a chronic disease, unavailingly) by exciting pain in distant parts of the body, by metastases and abscesses, by eruptions and suppurating ulcers.

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.
