It is to some extent a diaphoretic risperdal 4mg with mastercard, and has also a diuretic action which is important in these fevers cheap risperdal 3mg mastercard. The agent has been used to considerable extent as an emmenagogue discount 4mg risperdal, and is sometimes efficient in simple retention of the menses from cold discount risperdal 4mg overnight delivery. Note—As sedatives to nausea and gastric irritation, other agents, as hydrocyanic acid, ingluvin, ferrocyanide of iron, and ipecac in small doses, are efficient, and this property is fully described in the consideration of the therapy of those agents in other chapters. It is indicated when there is excessive mucous discharge, where catarrhal conditions exist in any locality, especially in the gastro-intestinal tract. Also where atonic diarrhea, or persistent diarrhea, accompanies prostrating disease; also where there is feeble capillary circulation of the mucous membranes, accompanied with phlegmenous ulceration. Therapy—It is a remedy for those conditions where the vital powers are at low ebb. It aids the nutrition, stimulating the absorption of food, and promotes the restoration of depraved blood. In any condition where the mucous surfaces have lost tone, and are throwing out a profuse discharge, it may be given with advantage. In conjunction with capsicum, its stimulating and tonic properties are plainly apparent. Combined with geranium, it is of superior benefit, where the patients have taken mercury and where ptyalism has been induced. Unlike most astringents, it materially improves excretion, secretion and the functional action of the glandular system. In chronic stomatitis, of whatever form, where the breath is bad, and there is slow ulceration, the mucous membranes being dark colored, this remedy in combination with other indicated remedies, will effect a rapid cure. If the stomach is foul, and the breath and fecal discharges are offensive, it should be given with an emetic, until the stomach is thoroughly evacuated. In combination with saguinaria it will be found useful in removing abnormal growths from the post-nasal cavity. Sufficiently diluted, and combined with hydrastis, it may be applied to Ellingwood’s American Materia Medica, Therapeutics and Pharmacognosy - Page 306 the mucous surfaces, in chronic nasal catarrh. It is valuable in the treatment of very severe forms of measles and scarlet fever. It is especially useful in the persistent sore throat of scarlet fever when the tissues are swollen and spongy. Given in conjunction with antispasmodics, it will improve the action of that class of remedies, in many forms of convulsions. Scudder claimed that the agent was a stimulant to the essential processes of digestion, blood-making and nutrition. The remedy may be given to advantage to those patients who are afflicted with chronic malarial symptoms and jaundice, with imperfect liver action, who are troubled with headaches, which are worse in the morning. The tongue is coated yellow, there is weakness and the patient complains of muscular soreness and aching in the limbs. No appetite, unrefreshing sleep, or where there are catarrhal conditions of the bile ducts resulting, in jaundice. Administration—The profound influence of this agent upon the nerve centers is quickly observed. Five drops of the specific medicine in three, four or even six ounces of water will be found sufficient. Fluid extracts or ordinary tinctures are not to be prescribed, because of uncertain strength. Physiological Action—Oenanthe crocata is extremely poisonous, and from its resemblance to common garden parsley has frequently caused death in men and animals. Toxic doses cause burning heat in the throat and stomach, with disturbance of intellect, cardialgia, nausea, vertigo, violent convulsions, furious delirium, or profound sleep; loss of sight, hearing and speech; rolling of the eye-balls upward, feeble pulse, abolition of sensation and of motive power, with increasing intellectual dullness. Ellingwood’s American Materia Medica, Therapeutics and Pharmacognosy - Page 307 There are universal chills, rose-colored spots on face, breast and arms; lividity and swelling of the face, with trismus and bloody froth from mouth and nostrils, stertorous breathing, coma, death. Autopsies performed on patients dead from the accidental use of this agent have shown an engorgement of the blood vessels of the brain and cord. The sinuses of the dura mater and the veins of the pia mater also were distended with blood, as were also the sinuses of the vertebrae. There was serous effusion in the cellular tissue beneath the arachnoid, in the ventricles and at the base of the brain. Fisk reported five cases cured, and other trustworthy investigators have had similar results. It is indicated in those cases which, instead of fullness of the capillary vessels of the brain and spinal cord, there is anemia of these organs more or less marked. It has proved of value in cases where epilepsy has resulted from injury, in cases where there is an impairment of the brain structure and imperfect cerebral circulation with impairment of the nutrition of the brain. It has not increased in reputation, nor has our knowledge of its action increased greatly during the past fifteen years. It may be given whenever irritating substances are retained in the intestinal tract and when convulsions are present from gastro-intestinal irritation. Violent and profound convulsions with acute enteritis, from swallowing the seeds of grapes, have been controlled at once by the writer, with large doses oil internally, and by using rectal injections of the oil very warm, large quantities of the seeds being removed and the local irritation soothed. Ellingwood’s American Materia Medica, Therapeutics and Pharmacognosy - Page 308 It is now generally used internally and externally in the treatment of appendicitis, and it is a most efficacious remedy. It is given freely, internally at regular intervals, and after its external application heat is kept constantly applied. Indicated remedies for the fever and for the prominent symptoms should not be overlooked. In these cases from six to twelve ounces is the necessary quantity for administration, repeated three or four times daily. It may be given per orem, and a quantity subsequently injected into the rectum after a bowel movement. If for an adult, two ounces, into which ten drops of laudanum has been rubbed, is injected, often the distress is so relieved that it need not be repeated. The injection of sweet oil is essential in impaction of the feces, and where there is great deficiency of intestinal secretion, or where scybala form, or where there are ulcers or fissures and great pain is induced by the presence of fecal matter in the rectum. A feeble, newly born infant may be quickly bathed in warm sweet oil and wrapped in cotton, and surrounded by heat and not dressed for several days. The oil can be wiped off once daily with a soft linen cloth and fresh warm oil applied. The child should then be wrapped in warm wrappings and not dressed for twenty-four hours. Olive oil is the best of lubricants, and the carbolized oil is used for chafing and upon hands and instruments in surgery, and in vaginal examinations, and in introducing bougies or catheters. If a stream of warm oil be forced into the urethra in spasmodic stricture just in advance of the catheter, the dilation may be made satisfactorily, and the catheter may be introduced when that act was previously impossible. Olive oil is exceedingly valuable in the treatment of sprained, bruised or contused parts, applied warm on absorbent cotton and kept hot. It acts as nutrition to the part, diffuses the heat and is markedly soothing in its influence. Olive oil is used to protect the mucous surfaces of the esophagus and Ellingwood’s American Materia Medica, Therapeutics and Pharmacognosy - Page 309 stomach when poisoning has occurred from the caustic alkalies. It also forms a neutral innocuous soap with the alkali and can subsequently be removed. In some cases a fatal loss of time occurs from depending upon this, when magnesia or lime water or soda or a soap solution should have been introduced to neutralize the acid. The substance is very mucilaginous, and an infusion will quickly become jelly-like. Weakness of the osseous structure, rickets, diarrhea and dysentery from local irritation in poorly nourished patients, Therapy—With some physicians this agent is very popular in the treatment of the above disorders. It is also useful in weak back, especially in those cases where, with weakness of the muscular structure of the back, there are symptoms of incipient disease of the spinal vertebrae. In the treatment of diarrhea and dysentery, whether acute or accompanying protracted fevers, the agent is said to be very beneficial, especially if accompanied with great weakness. It has been given in various form of female weakness, particularly where there was severe leucorrhea. Ellingwood’s American Materia Medica, Therapeutics and Pharmacognosy - Page 310 The Wm.

These drugs have multiple pharmacological and toxicological properties and are capa- ble of producing severe effects independent of the antidepressant response. Practitioners may also prefer these substances because of familiarity with their use and pharmacological actions (1–3). On entry into the body, these simple amines promote release of noradrenalin in the peripheral nervous system and are capable of causing severe hypertensive crisis. In another instance (15), 24 h after discon- tinuing phenelzine, a patient ingested a tablet containing ephedrine, caffeine, and theo- phylline. Eight hours later, she developed encephalopathy, neuromuscular irritability, hypotension, sinus tachycardia, rhabdomylosis and hyperthermia. Features of this syndrome might not develop until 6–12 h after overdose and include hyperpyrexia, disseminated intravascular coagulation, convulsions, coma, and muscle rigidity (19). It bears reem- phasis that the critical issue of this interaction is that it occurs between agents that act in concert to increase the amount of free serotonin. Therefore, because of the potential for severe toxicity, patients must follow a well-defined dosing regimen, be carefully monitored, and be informed of the immediate need for medical intervention should side effects occur. They also noted that the interaction with meperidine is of two distinct forms, excitatory and depressive. Meperidine is the only commonly used narcotic anal- gesic reported to have elicited this excitatory response, which occurs in approximately 20% of patients treated with this drug combination. This latter interaction can occur with any analgesic and results in symptoms characteristic of analgesic over- 152 Danielson dose. If recognized beforehand the interaction can be avoided by adjustment of the narcotic analgesic dosage. The use of isoniazid has increased recently largely as a result of treatment of human immunodeficiency virus infections. The most prominent members of the group are amitriptyline, imipramine, doxepin, dothiepin, and clomipramine. Clinical evidence suggests that suicidal ideation is not uncommon dur- ing a depressive illness (46–48) and that acting upon such impulses might lead to use of any available drug for improper, dangerous purposes. Tissue concentrations at intoxication may be only low multiples of the therapeutic level. Symptoms such as sedation, blurred vision, dry mouth, and urinary retention appear to be related to the antimuscarinic actions. In a small number of cases, involvement of other organs has also been observed (62). Chemically, imipramine differs from amitriptyline only by replacement of the C-5 exocyclic double bond by a nitrogen atom. Antidepressant and anticholinergic activities are retained after insertion of oxygen or sulfur heteroatoms at C-10 of the ethylene bridge (cf. It is also important to note that the C-5 double bond in amitriptyline introduces a plane of symmetry that passes through C-5 and the C-10, C-11 bond of the molecule. Analogs or metabolites of amitriptyline can therefore be separated into isomers, dif- fering only by introduction of substituents into the half of the molecule on the same (cis or Z) or opposite side of the double bond (trans or E) as the ethylamino aliphatic chain. This type of isomerism exists with amitriptyline, doxepin, and dothiepin but is absent for imipramine and clomipramine because of the ready inversion of the bridge- head nitrogen atom. Doxepin, for example, is marketed as an irrational 85:15, E:Z mixture and the less active E-isomer of N-desmethyldoxepin is metabolized more quickly than Z-N-des- methyldoxepin (67,68). Useful antidepressant activity is lost after dehydrogenation of the two-carbon ethylene bridge (C-10, C-11) and cyclobenzaprine is employed clinically as a centrally acting muscle relaxant. Some conflict as to the overdose risk of cyclobenzaprine is present in the literature. Some data suggest that cyclobenzaprine is an overdose risk in its own right (69,70). However, in a 5-yr multi- center study of over 400 cyclobenzaprine overdoses, no deaths occurred. Arrhythmias were infrequent and cyclobenzaprine did not appear to be life threatening after doses up to 1 g (71). Finally, carbamazepine differing by C-10, C-11 unsaturation, plus modifi- cation of the side chain at C-5, lacks both antidepressant and anticholinergic actions. The rationale in support of drug monitoring has been summar- ized for clomipramine (78). Clinical evidence suggests that, during treatment with ami- triptyline, efficacy is greatest when combined levels in serum of amitriptyline and its N-desmethyl metabolite, nortriptyline, are in a range between approximately 100 and 200 ng/mL (79,80). Other studies suggest levels of imipramine in blood greater than a threshold level near 180 ng/mL (81) or in a range of 200–300 ng/mL were consistent with a good clinical response (82,83). This suggests only a three- to four- fold difference between therapeutic and toxic amounts in blood. Figure 2 illustrates the common metabolic transformations undergone by ami- triptyline. These demethylated homologues accumulate in plasma and tissues and retain the pharmacological properties of the parent drug. In fact, the mono-N-demethylated metabolites of amitriptyline and imipramine, nortriptyline and desipramine respectively, are marketed in their own right as antidepressant drugs (70) and are toxic at levels in blood similar to their N,N-dimethyl- homologs (69). For exam- ple, clinical observations suggest the presence of an antidepressant response among patients treated with E-10-hydroxynortriptyline (89) and a superior clinical outcome was measured in patients favoring higher plasma levels of amitriptyline and Z-10- hydroxymetabolites in comparison to patients favoring formation of nortriptyline and E-10-hydroxy metabolites (90). In these experiments 2-hydroxyimipramine produced a significantly greater inci- dence of life-threatening arrhythmias than did its parent, imipramine (91). In comparison, E-10-hydroxynortriptyline produced fewer cardiac arrhythmias than did nortriptyline or Z-10-hydroxynortriptyline (92).

The author and the publishers do not accept responsibility or legal liability for any errors in the text or for the misuse or misapplication of material in this book. During the past several decades, however, pioneering work has revealed many of the complexities of cardiac arrhythmias and of the drugs used to treat them. To the dismay of most reasonable people, the old, convenient viewpoint finally proved utterly false. Indeed, in the decade since the first edition of this book appeared, the widespread notion that antiarrhythmic drugs are a salve for the irritated heart has been, appropriately, completely reversed. Every clinician worth his or her salt now realizes that antiarrhythmic drugs are among the most toxic substances used in medicine, they are as likely as not to provoke even more dangerous arrhythmias, and, indeed, the use of most of these drugs in most clinical situations has been associated with an increase (and not a decrease) in mortality. This newfound respect for (if not fear of) antiarrhythmic drugs has been accompanied by the comforting murmurs of an elite army of electrophysiologists, assuring less adept clinicians that, really, there is no reason to worry about these nasty substances anymore. After all (they say), what with implantable defibrillators, radiofrequency ablation, and other emerging technologies (that, by the way, only we are qualified to administer), the antiarrhythmic drug as a serious clinical tool has become nearly obsolete. It is certainly true that the use of antiarrhythmic drugs has been considerably curtailed over the past decade or so and that other emerging treatments have led to significantly improved outcomes for many patients with cardiac arrhythmias. But neither the widely acknowledged shortcomings of these drugs nor the dissemination of new technologies has eliminated the usefulness of antiarrhythmic drugs or obviated the need to apply them, when appropriate, in the treatment of patients with cardiac arrhythmias. Consider that implantable defibrillators, while in clinical use for over 25 years, are still indicated for only a tiny proportion of pa- tients who are at increased risk of arrhythmic death and are actually v vi Preface implanted in only a small proportion of these. Until these devices are made far cheaper, easier to implant, and more reliable than they are today (changes that would require dramatic—and thus unlikely— alterations in the business models of both the companies that make them and the doctors who implant them), they will never be used in the vast majority of patients who are at risk of arrhythmic death. And consider that ablation techniques to cure atrial fibrillation—the ar- rhythmia that produces the greatest cumulative morbidity across the population—have failed, despite prolonged and dedicated efforts, to become sufficiently effective or safe for widespread use. And finally, consider that with a deeper understanding of cellular electrophysiol- ogy, drug companies are now beginning to “tailor” new compounds that might be more effective and less toxic than those in current use, and that some future generation of antiarrhythmic drugs— possibly even some of the investigational drugs discussed herein— may offer a very attractive alternative to certain expensive or risky technologies. It remains important, therefore, for any health-care professional caring for patients who are at risk of developing cardiac arrhyth- mias (and not just the electrophysiologists) to understand some- thing about antiarrhythmic drugs. Accordingly, this book is intended for nonexperts—the practitioners, trainees, and students—who are most often called upon to make decisions regarding actual patients with cardiac arrhythmias. The book attempts to set out a framework for understanding antiarrhythmic drugs: how they work, what they actually do to improve (or worsen) the cardiac rhythm, and the fac- tors one must consider in deciding when and how to use them. Such a framework, it is hoped, will not only serve as a guidepost in making clinical decisions, but will also provide a basis for interpreting new information that comes to light on antiarrhythmic drugs and their place in the treatment of cardiac arrhythmias. Part 1 is an introduction to basic principles—the mechanism of cardiac arrhythmias and how antiarrhythmic drugs work. Part 2 discusses the clinically relevant features of the drugs themselves, including emerging investigational drugs that appear to show promise. Part 3 draws on this basic infor- mation to explore the treatment of specific cardiac arrhythmias and emphasizes the current roll of antiarrhythmic drugs in managing these arrhythmias. Accord- ingly, when a choice had to be made between simplicity and Preface vii complexity, simplicity prevailed in almost every case. The author recognizes that some colleagues may not agree with an approach that risks oversimplification of an inherently complex topic. It is an ap- proach, however, that reflects a deep-seated belief—by keeping the basics simple, the specifics (clinical cases and scientific reports) can be more readily weighed, categorized, absorbed, and implemented. Acknowledgments The author thanks Gina Almond, Publisher at Blackwell Publishing, for asking me to consider writing a second edition to this book, and Fiona Pattison, Senior Development Editor at Blackwell, for helping to shepherd me through the process of actually doing so. The author also thanks Anne, Emily, and Joe Fogoros for once again overlooking the temporary inattentiveness that always seems to accompany such endeavors. Indeed, it is nearly im- possible withoutafirm understanding of the basic mechanismsof cardiac tachyarrhythmias and the basic concepts of how antiarrhyth- mic drugs work. Chapter 1 reviews the normal electrical system of the heart and the mecha- nismsand clinical features of the major cardiac tachyarrhythmias. Chapter 2 examines the principles of how antiarrhythmic drugs af- fect arrhythmias. The electrical system of the heart On a very fundamental level, the heart isan electrical organ. The electrical signals generated by the heart not only cause muscle con- traction (by controlling the fluxofcalcium ionsacross the cardiac cell membrane) but also organize the sequenceofmuscle contrac- tionwith each heartbeat, thusoptimizing the pumping action of the heart. In addition,and especially pertinent to the subjectofthis book, the pattern and timing of the cardiac electrical signals deter- mine the heart rhythm. Thus, a well-functioning electrical systemis vital for adequate cardiacperformance. The fibrous skeletonis electrically inert, and therefore stops the electrical impulse. Onceon the ventricular side, the electrical impulse follows the His-Purkinje system as it divides first into the right and left bun- dle branches and theninto the Purkinje fibers. The Purkinje fibers speed the impulse to the furthermost reaches of the ventricular my- ocardium. In this way, the electrical impulse israpidly distributed throughout the ventricles. Mechanismsofcardiac tachyarrhythmias 5 The heart’s electrical system thusorganizes the sequenceofmy- ocardial contractionwith each heartbeat. Cardiac action potential The electrical impulse of the heart isactually the summation of thou- sandsoftiny electrical currents generated by thousandsofindivid- ual cardiaccells. The electrical activity of an individual cardiaccell is described by the cardiac actionpotential (Figure 1. Fortu- nately, for our purposes there are onlyafew thingsone needsto know about the actionpotential, and these are reasonably simple to understand. The voltage differenceacross the cell membrane(normally –80 to –90 mV) is called the transmembrane potential and is the result of an accumulation of negatively chargedmolecules within the cell. The magnitude of the transmembrane potential remains fixed through- out the lives of most living cells. When excitable cells are stimulatedinjust the right way, a variety of tiny channels in the cell membrane are induced to open and close in a complex sequence, which allows various electrically charged particles—ions—to pass backand forth across the membrane in an equally complex sequence. The movementofelectrical current across the cell membraneoccurs in a very stereotypic pattern and leadstoapatterned sequenceofchanges in the transmembrane po- tential. When the stereotypic changes in voltage are graphed against time, the result is the cardiac actionpotential.

Perspiration comes too easily from slight motion; even while sitting discount risperdal express, he is attacked with perspiration all over, or merely on some parts; e. Daily morning sweats, often causing the patient to drip, this for many years, often with sour or pungent-sour smell. Increasing susceptibility to colds either of the whole body (often even from repeatedly wetting the hands, now with warm water, then with cold, as in washing clothes), or only susceptibility of certain parts of the body, of the head, the neck, the chest, the abdomen, the feet, etc. Watery swelling, either of the feet alone, or in one foot, or in the hands, or the face, or the abdomen, or the scrotum, etc. Attacks of paralytic weakness and paralytic lassitude of the one arm, the one hand, the one leg, without pain, either arising suddenly and passing quickly, or commencing gradually and constantly increasing. No person who is not psoric ever suffers the least after- effects from such causes. Also similar attacks of weakness with adults in the legs, so that in walking one foot glides this way and the other that way, etc. While walking in the open air sudden attacks of faintness, especially in the legs. The predisposition to spraining and straining the joints at a mis-step, or a wrong grasp, increases at times even to dislocation; e. The snapping and cracking of the joints at any motion of the limb increases with a disagreeable sensation. The painful cramps in some of the muscles increase and come on without appreciable cause. Involuntary turning and twisting of the head, or the limbs, with full consciousness (St. Continuous, constant trembling, also in some cases beating with the hands, the arms, the legs. Attacks of loss of consciousness, lasting a moment or a minute, with an inclination of the head to the one shoulder, with or without jerks of one part or the other. Sleepiness during the day, often immediately after sitting down, especially after meals. Difficulty in falling asleep, when abed in the evening; he often lies awake for hours. Sleeplessness, from anxious heat, every night, an anxiety which sometimes rises so high, that he must get up from his bed and walk about. As soon as he closes his eyes, all manner of fantastic appearances and distorted faces appear. In going to sleep, she is disquieted by strange, anxious fancies; she has to get up and walk about. Very vivid dreams, as if awake; or sad, frightful, anxious, vexing, lascivious dreams. Somnambulism; he rises up at night, while sleeping with closed eyes, and attends to various duties; he performs even dangerous feats with ease, without knowing anything about them when awake. Various sorts of severe pains at night, or nocturnal thirst, dryness of the throat, of the month, or frequent urinating at night. Early on awaking, dizzy, indolent, unfreshed, as if he had not done sleeping and more tired than in the evening, when he lay down; it takes him several hours (and only after rising) before he can recover from this weariness. After a very restless night, he often has more strength in the morning, than after a quiet, sound sleep. Intermittent fever, even when there are no cases about, either sporadic or epideinic,1 or endemic; the form, duration and type of the fever are very various; quotidian, tertian, quartan, quintan or every seven days. Every evening, heat, with a rush of blood to the head, with red cheeks, also at times an intervening chill. Intermittent fever of several weeks duration, followed by a moist itching eruption lasting several weeks, but which is healed again during a like period of intermittent fever, and alternating thus for years. Melancholy, palpitation and anxiousness causes her at night to wake up from sleep (mostly just before the beginning of the menses). With others, this oppression is associated with anxious images and thoughts, and seems to rise from them, while with others, there is oppression without anxious ideas and thoughts. Without feeling any anxiety, or anxious thoughts, therefore also, without any oneÕs perceiving such anxiety in them, apparently in the full exercise of their reason, they are impelled, urged, yea, compelled by a certain feeling of necessity, to self-destruction. They are only healed by a cure of the Psora, if their utterances are noticed in time. I say in time, for in the last stages of this kind of insanity it is peculiarly characteristic of this disease, not to utter anything about such a determination to anyone. This frenzy manifests itself in fits of one-half or of whole hours, usually in the end daily, often at certain times of the day. But besides these fits of destructive mania, such persons have usually also fits of anxious oppression, which seem, however, to be independent of the former fits, and come at other hours, accompanied partly with pulsation in the pit of the stomach, but during these they are not tormented with the desire of taking their own life. These attacks of anxiety which seem to be more of a bodily nature, and are not connected with the other train of thoughts, may also be lacking, while the fits of suicidal mania rule in a high degree; they may also return, when that mania is in a great part extinguished through the anti-psoric remedies, so that the two seem to be independent of one another, though they have the same original malady for their foundation. Fright caused by the merest trifles; this often causes perspiration and trembling. Disinclination to work, in persons who else are most industrious; no impulse to occupy himself, but rather the most decided repugnance thereto. 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 coining 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. Occurrences affecting the mind, not only such as are of a sad and vexatious kind, but also those of a joyous kind, cause surprising ailments and disorders; touching tales, yea, even thinking of them and recalling them, cause a tumultuous excitement of the nerves, and drive the anxiety into the head, etc. Even a little reading about indifferent things, or looking attentively at an object; e. In many cases even moderate bodily motion, or speaking, also warmth, cold, open air, wetting the skin with water, etc. Not a few suffer even in their room from a sudden change of the weather, while most of these patients complain during stormy wet weather, few of dry weather with a clear sky. The full moon also with some persons and the new moon with other, has an unfavorable erect. 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 (intolerably voluptuously) itching pustules of itch on his skin, or (since the itch-disease is considered as something disgraceful) is not willing to acknowledge it? 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 are 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 I have on my side an overpowering analogous probability, i. 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. 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. We now proceed to the medical Homoeopathic treatment of the illimitably large number of chronic diseases, which, after the above gained knowledge of their threefold nature, has not, indeed, become easy, but - what without this knowledge was before impossible - has at last become Possible, since the homoeopathically specific remedies for each one of these three different miasmata have in great part been discovered. The first two miasmata, which cause by far the smaller part of the chronic diseases, the venereal chancre-disease (syphilis) and the figwart-disease (sycosis), with their sequelae, we will treat first, in order that we may have a free path to the therapeutics of the immeasurably greater number of the various chronic diseases which spring from Psora. First, then, concerning sycosis, as being that miasma which has produced by far the fewest chronic diseases, and has only been dominant from time to time. This figwart-disease, which in later times, especially during the French war, in the years 1809-1814, was so widely spread, but which has since showed itself more and more rarely, was treated almost always, in an inefficient and injurious manner, internally with mercury, because it was considered homogeneous with the venereal chancre-disease; but the excrescences on the genitals were treated by Allopathic physicians always in the most violent external way by cauterizing, burning and cutting, or by ligatures. These excrescences usually first manifest themselves on the genitals, and appear usually, but not always, attended with a sort of gonorrhoea* from the urethra, several days or several weeks, even many weeks after infection through coition; more rarely they appear dry and like warts, more frequently soft, spongy, emitting a specifically fetid fluid (sweetish and almost like herring- brine), bleeding easily, and in the form of a coxcomb or a cauliflower (brassica botrytes). These, with males, sprout forth on the glans and on, or below, the prepuce, but with women, on the parts surrounding the pudenda; and the pudenda themselves, which are then swollen, are covered often by a great number of them.
