These are some of the leading symptoms observed by me, which, if they are often repeated, or become constant, show that the internal Psora is coming forth" from its latent state. They are at the same time the elements, from which (under unfavorable external conditions) the itch-malady, as it manifests itself, composes the illimitable number of chronic diseases, and with one man assumes the one form, with another another, according to the bodily constitution, defects in the education, habits, employment and external circumstances, as also modified by the various psychical and physical impressions. It thus unfolds into manifold forms of disease, with so many varieties, that they are by no means exhausted by the disease-symptoms enumerated in the pathology of the old-school, and erroneously designated there as well-defined, constant and peculiar diseases.*
*They bear the following names: Scrofula, rickets, spina ventosa, atrophy, marasmus, consumption, pulmonary consumption, asthma, tabes mucosa, laryngeal phthisis, chronic catarrh, constant coryza, difficult dentition, worms and consequent diseases, dyspepsia, ab-domina, cramps, hypochondria, hysteria, dropsy, dropsy of the ab-domenl dropsy of the ovaries, of the uterus, hydrocele, hydrocephalus, amenorrhoea, dysmenorrhoea, uterine hemorrhages, hemate-mesis, hemoptysis and hemorrhages, vaginal hemorrhages, dysuria.
These are the characteristic secondary symptoms* of the long-unacknowledged, thousand-headed monster, pregnant with disease, the Psora, the original miasmatic malady which now makes its manifest appearance.+ ischuria, enuresis, diabetes, catarrh of the bladder, hematuria, nephralgia, gravel of the kidneys, stricture of the urethra, stricture of the intestines, blind and running piles, fistula of the rectum, difficult stools, constipation, chronic diarrhoea, induration of the liver, jaundice, cyanosis, heart diseases, palpitation, spasms of the chest, dropsy of the chest, abortion, sterility, metro-mania, impotence, induration of the testicles, dwindling of the testicles, prolapsus uteri, inversion of the womb, inguinal, femoral and umbilical hernias, dislocations of the joints from an internal cause, curvature of the spine, chronic inflammation of the eyes, fistula lachrymalis, short-sightedness and long-sightedness, day blindness and night blindness, obscuration of the cornea, cataracts, glaucoma, amaurosis, deafness, deficient smell or taste, chronic one-sided headache, megrim, tic douloureux, tinea capitis, scab, crusta lactea, tetters (herpes), pimples, nettlerash, encysted tumors, goitre, varices, aneurism, erysipelas, sarcomas, osteosarcoma, scirrhus, cancer of the lips, cheeks, breast, uterus, fungus hematodes, rheumatism, gout in the hips, knotty gout, podagra, apoplectic fits, swoons, vertigo, paralysis, contractions, tetanus, convulsions, epilepsy, St. Vitus' dance, melancholy, insanity, imbecility, nervous debility, etc.
*The supreme royal councillor Kopp, an Allopath, who is unwillingly and only half and half approaching Homoeopathy, pretends to have seen chronic diseases disappear of themselves - he may have seen some particular symptoms disappear, which symptoms the old school, in its shortsighted fashion, considered with him as so many entire diseases!
I will grant that the doctrine, that "all chronic non-venereal diseases which are not extinguishable by the vital force, in an orderly course of life, while external circumstances are favorable, but which even increase with the years, are of psoric origin," is for all who have not fully weighed my reasons and for all narrow-minded people, too great, too overwhelming. But it is none the less true. Or should we regard such a chronic disease as not being psoric, because the patient cannot remember that he at sometime, all the way back to his birth, has had several or more (intolerable voluptuously) itching pustules of itch on his skin, or (since the itch-disease is considered as something disgraceful) is not willing to acknowledge it? His non-acknowledgment here proves nothing to the contrary.
Since at all times, all the innumerable chronic diseases resulting from an acknowledged preceding itch (when this has not been cured) are ineradicable through the vital force, and advance in their equable course as psoric ailments, and continually aggravated; so long as the doubters of the psora doctrine cannot show me any other source which is at least as probable for a (non-veneric) ailment, which, despite of favorable external conditions, correct diet, good morality and vigorous bodily constitution, nevertheless increases every year, without any preceding infection from itch so far as memory goes; so long-as I have on my side an overpowering analogous probability, i. e., joo to I, that also the individual cases of chronic disease, which show a like progression, probably also are, yea, must be of a psoric nature, although the patient cannot or will not remember a preceding infection.
It is easy to doubt matters which cannot be laid before our ocular vision, but in itself this doubt proves nothing at all, for according to the old rule of logic: negantis est probare.
To prove the Psoric nature of these chronic diseases without acknowledged infection, we do not even need the fact that the anti-psoric remedies prove effectual therein; this serves only like the proof to a correctly solved mathematical problem.
Now since, in addition, the other remedies, although also selected according to the similarity of their symptoms, do not by far yield so durable and thorough a cure in such chronic diseases, as those which are recognized as anti-psoric, and which are selected in as Homoeopathic a manner, because these more than the others are adequate to the whole extent of the endless number of symptoms of the great Psora malady: I do not see why men will deny to the latter the title of the especially anti-psoric remedies, unless this springs from dogmatism.
And just as little is there any good reason for contradicting me, when I (Organon, # 73) explain the acute diseases which return from time to time; e.g., inflammations of the throat, of the chest, etc., as flaming up from a latent Psora, simply because their inflammatory state, as they say, is mostly to be combatted by means of the anti-phlogistic remedies, which are not anti-psoric; i. e.t Aconite, Belladonna, Mercury and the like. These, nevertheless, have their source in a latent Psora, because their customary return cannot be prevented by anything but a final cure with anti-psoric remedies.
