§ 71
As it is now no longer a matter of doubt that the diseases of mankind consist merely of groups of certain symptoms, and may be annihilated and transformed into health by medicinal substances, but only by such as are capable of artificially producing similar morbid symptoms (and such is the process in all genuine cures), hence the operation of curing is comprised in the three following points:
I. How is the physician to ascertain what is necessary to be known in order to cure the disease?
II. How is he to gain a knowledge of the instruments adapted for the cure of the natural disease, the pathogenetic powers of the medicines?
III. What is the most suitable method of employing these artificial morbific agents (medicines) for the cure of natural disease?
§ 72
With respect to the first point, the following will serve as a general preliminary view. The disease to which man is liable are either rapid morbid processes of the abnormally deranged vital force, which have a tendency to finish their course more or less quickly, but always in a moderate time – these are termed acute diseases; – or they are diseases of such a character that, with small, often imperceptible beginnings, dynamically derange the living organism, each in its own peculiar manner, and cause it gradually to deviate from the healthy condition, in such a way that the automatic life energy, called vital force, whose office is to preserve the health, only opposes to them at the commencement and during their progress imperfect, unsuitable, useless resistance, but is unable of itself to extinguish them, but must helplessly suffer (them to spread and) itself to be ever more and more abnormally deranged, until at length the organism is destroyed; these are termed chronic diseases. They are caused by infection with a chronic miasm.
§ 73
As regards acute diseases, they are either of such a kind as attack human beings individually, the exciting cause being injurious influences to which they were particularly exposed. Excesses in food, or an insufficient supply of it, severe physical impression, chills, over heatings, dissipation, strains, etc., or physical irritations, mental emotions, and the like, are exciting causes of such acute febrile affections; in reality, however, they are generally only a transient explosion of latent psora, which spontaneously returns to its dormant state if the acute diseases were not of too violent a character and were soon quelled. Or they are of such a kind as attack several persons at the same time, here and there (sporadically), by means of meteoric or telluric influences and injurious agents, the susceptibility for being morbidly affected by which is possessed by only a few persons at one time. Allied to these are those diseases in which many persons are attacked with very similar sufferings from the same cause (epidemically); these diseases generally become infectious (contagious) when they prevail among thickly congregated masses of human beings. Thence arise fevers1, in each instance of a peculiar nature, and, because the cases of disease have an identical origin, they set up in all those they affect an identical morbid process, which when left to itself terminates in a moderate period of time in death or recovery. The calamities of war, inundations and famine are not infrequently their exciting causes and producers – sometimes they are peculiar acute miasms which recur in the same manner (hence known by some traditional name), which either attack persons but once in a lifetime, as the smallpox, measles, whooping-cough, the ancient, smooth, bright red scarlet fever2 of Sydenham, the mumps, etc., or such as recur frequently in pretty much the same manner, the plague of the Levant, the yellow fever of the sea-coast, the Asiatic cholera, etc.
1 The homoeopathic physician, who does not entertain the foregone conclusion devised by the ordinary school (who have fixed upon a few names of such fevers, besides which mighty nature dare not produce any others, so as to admit of their treating these disease according to some fixed method), does not acknowledge the names goal fever, bilious fever, typhus fever, putrid fever, nervous fever or mucous fever, but treats them each according to their several peculiarities.
2 Subsequently to the year 1801 a kind of pupura miliaris (roodvonk), which came from the West, was by physicians confounded with the scarlet fever, notwithstanding that they exhibited totally different symptoms, that the latter found its prophylatic and curative remedy in belladonna, the former in aconite, and that the former was generally merely sporadic, while the latter was invariable epidemic. Of late years it seems as if the two occasionally joined to form an eruptive fever of a peculiar kind, for which neither the one nor the other remedy, alone, will be found to be exactly homoeopathic.
§ 74 Fifth Edition
Among chronic diseases we must still, alas!, reckon those so commonly met with, artificially produced in allopathic treatment by the prolonged use of violent heroic medicines in large and increasing doses, by the abuse of calomel, corrosive sublimate, mercurial ointment, nitrate of silver, iodine and its ointments, opium, valerian, cinchona bark and quinine, foxglove, prussic acid, sulphur and sulphuric acid, perennial purgatives, venesections, leeches, issues, setons, etc., whereby the vital force is sometimes weakened to an unmerciful extent, sometimes, if it do not succumb, gradually abnormally deranged (by each substance in a peculiar manner) in such a way that, in order to maintain life against these inimical and destructive attacks, it must produce a revolution in the organism, and either deprive some part of its irritability and sensibility, or exalt these to an excessive degree, cause dilatation or contraction, relaxation or induration or even total destruction of certain parts, and develop faulty organic alterations here and there in the interior or the exterior1 (cripple the body internally or externally), in order to preserve the organism from complete destruction of the life by the ever-renewed, hostile assaults of such destructive forces.
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.
