29. With relation to diet and mode of life, whatever is injurious to the action of the remedies must be avoided, and with lingering diseases we must consider the age, occupation and social conditions of the patient. Strict diet alone will hardly ever cure a disease, and it is unreasonable to insist upon a mode of life which is impossible for a patient to follow; only that which is generally injurious to health, ought to be carefully avoided.
30. Rich patients must walk more than they usually do; moderate dancing, rural entertainments, music and amusing lectures, theaters once in a while are allowable, but they must never play cards; riding horseback or in a carriage ought to be restricted. All amorous intercouse and sensual excitement, reading lewd novels, superstitious and exciting books, are to be carefully avoided.
31. The literary man ought to take much exercise in the open air; in bad weather do some light mechanical work in the house. During treatment he ought to limit his literary work, and in mental diseases reading must be positively forbidden.
32. Chronic patients must avoid domestic medicines and abstain from perfumes. Those who are accustomed to wear wool may continue to do so, but as the case progresses and the weather becomes warmer, cotton or linen ought to be substituted. Daily ablutions are often more advisable than baths.
33. In regard to eating, one should consent to restrictions in order to be freed from a troublesome chronic disease, and only in abdominal affections restrictions are more necessary. In regard to beverages, coffee has pernicious effects upon mind and body. Young people do not need it, and older persons ought to wean themselves generally from its use, and be satisfied with roast rye or wheat, whose smell and taste is very much like coffee. Tea ought to be entirely avoided during treatment of chronic diseases. Old people cannot be suddenly deprived of their wine, but by mixing it with water and sugar, they can gradually reduce its strength; in fact, the patient cannot be too abstemious in relation to alcoholic beverages; it is a law of nature that the apparent increase of strength and animal heat consequent upon the use of ardent spirits will be followed by a state of depression and diminution of heat.
34. Beer is so much adulterated, that it becomes injurious to health; vinegar and lemon juice are especially hurtful to those who are affected with nervous and abdominal complaints; sweet fruits may be used moderately; beef, wheat or rye bread, cow's milk and fresh butter are the most natural food, hence also for chronic patients. Next to beef comes mutton, game, old chickens, young pigeons. Goose, duck, or pork are less admissible. Salt and smoked meats ought to be used in great moderation. Fish ought to be boiled and eaten without any spiced sauces; herrings and sardines in moderate quantities. Moderation in both eating and drinking is a sacred duty for all chronic patients.
35. Restriction in the use of tobacco is especially-necessary when the intellectual functions are affected, when the patient does not sleep well, is dyspeptic and constipated.
36. Excessive fatigue, working in marshy regions, injuries and wounds, excessive heat or cold, starvation, poverty, unwholesome food are less capable of rousing latent psora or aggravating a manifest psoric disease than an unhappy marriage or a gnawing conscience. Grief and sorrow are the chief causes which either develop latent psora or aggravate an already existing secondary psoric affection.
37. Mineral springs and all medicinal influences ought to be avoided and when the patient used them, he ought to abstain for some time from all medicines and follow a strict diet in the country.
38. All excesses injure mind and body; by vicious practices the most robust bodies often fail and the latent psora entering in combination with a badly managed syphilitic poison gives origin to most distressing diseases. We must then remove first the psoric poison and thus prevent all secondary chronic affections.
39. The physician must never interrupt the action of an antipsoric remedy nor exhibit an intermediate remedy on account of every trifling ailment; a carefully selected remedy should act till it has completed its effect.
40. Suppose the remedy calls out symptoms which have existed before, this apparent aggravation and the development of new symptoms show that the remedy has attacked the disease in its inmost nature, and it must be left undisturbed.
41. Should the remedy cause new symptoms, which may be supposed to be inherent to the medicine, the remedy should be permitted to act for a while and generally these symptoms will disappear; but if they are troublesome, they show that the remedy was not properly chosen, and an antidote, if known, must be given or another suitable antipsoric selected.
42. A homoeopathic aggravation is a proof that a cure may be anticipated with certainty; but if the original symptoms continue with the same intensity, it shows that too large a dose made the cure impossible, neutralizing its genuine homoeopathic effects and causing a medicinal disease by the side of the natural disturbances. We then select an antipsoric which corresponds to the symptoms of the natural and of the artificial disease. Should the same antipsoric be still indicated, we must give it in a much higher potency and in a more minute dose. The doses can scarcely be too much reduced, provided the effects of the remedy are not disturbed by improper food.
43. The physician ought to avoid three mistakes, that the dose can be too small, the improper use of the remedy, and in not letting the remedy act a sufficient length of time. The surest and safest way of hastening a cure is to let the medicine act as long as the improvement of the patient continues.
44. Psora is a troublesome thing to deal with, exacerbations show only that the disease is writhing under the action of the remedy, but they will progressively diminish in frequency and intensity if not interfered with by a new remedy, for the benign action of the former remedy, which was manifesting itself, is thus probably lost.
