"The same reasoning will apply to the operation of emetics and cathartics; for not only is the peristaltic motion either greatly quickened or inverted, according to the urgency of the distress, but both the mucous glands and the exhalent arteries pour forth their fluids in abundance to wash away the offending matter, which at one time acts chemically, at others mechanically."
If a horse, or an ox, be wounded in the foot with a nail, and a portion of it is broken off and remains in the wound, inflammation sets in, producing suppuration, and the nail is discharged.
A few days ago, we were called to see a horse, said to have swelling on the tarsus, (hock.) On an examination, it proved to be an abscess, well developed; the matter could be distinctly felt at the most prominent part. We should certainly have been justified (at least in the eyes of the medical world; and then it would have looked so "doctor-like"!) in displaying a case of instruments and opening the tumor. If ulceration, gangrene, &c., set in and the horse ultimately became lame, no blame could be attached to us, because the practice is scientific!—recognized by the schools as good and efficient treatment. What was to be done? Why, it was evident that we could not do better than to aid nature. A relaxing, anti-spasmodic poultice was confined to the parts, and in six hours after, the sac discharged its contents, and with it a piece of splinter two inches in length. The pain immediately ceased, and the animal is now free from lameness. We here see the design of nature: the consequent inflammation was to produce suppuration, and make an outlet for the splinter.
Professor Kost says, "The laws of all organic life are remarkably peculiar; they possess, in an eminent degree, the power of self-regulation. When interrupted, disease, indeed, supervenes; but unless the circumstances are particularly unfavorable, the physiological state will soon be restored. All observation most clearly corroborates this fact. The healing of wounds, restoration of fractured bones, expulsion of obtruded substances, and particularly the manner in which extravasated matter or pus is removed from internal organs, as in case of abscess in the liver, in which exit may be gained by ulceration through the parietes, or by an adhesion to and ulceration into the intestines, or even by the adhesions to the diaphragm and lungs, in such a manner as, by ulceration into the bronchia, a passage may be gained, and the pus thus removed by expectoration,—all evince a most singular conservative power. What is most remarkable in cases like the latter, is, that the adhesions are so formed as to prevent the escape of the pus into the peritoneal sac, which accident must inevitably prove fatal.
"Some very interesting experiments have been performed to test the restorative power of the different tissues of the animal body. If a portion of the intestines of a dog be taken out, and tied, so as to obstruct completely the passage, it will be found that the adjacent portions of the intestine will reunite, the ligature will separate into the canal and be discharged, and the gut will heal up so as to preserve its normal continuity, and the animal, in a fortnight, will have recovered entirely from the effects of this fearful operation.
"When noxious or poisonous substances are thrown into any of the cavities of the body from which their escape is impracticable, a cyst will often form around them, and they thus become isolated from absorption and the circulation, so as to prevent their doing harm.
"The less remarkable instances of this character are of more common occurrence; and the self-regulating power of the laws of life, alias vis conservatrix naturæ, is so universally known and depended on, that it is rare, indeed, that indisposed persons take medicine, until they have first waited at least a little, to see what nature would do for them; and they are seldom disappointed, as it may perhaps be safely asserted, that nine tenths of all the attacks of disease (taking the slight indispositions; for such are most of them, as they are checked before they become severe) are warded off by the vital force, unassisted. Such, then, are the facts deduced from observing the operations of nature in disease unassisted."
Dr. Beach says, "We are well aware, from what passes in the system daily, that the Author of nature has wisely provided a principle which is calculated to remove disease. It is very observable in fevers. No sooner is noxious or morbid matter retained in the system, than there is an increased action of the heart and arteries, to eliminate the existing cause from the skin; or it may pass off by other outlets established for that purpose. With what propriety, then, can this provision of nature be denied, as it is by some? A noted professor in Philadelphia or Baltimore ridicules this power in the constitution; he says to his class, 'Kick nature out of doors.' It was this man, or a brother professor, who exclaimed to his class, 'Give me mercury in one hand and the lancet in the other, and I am prepared to cope with disease in every shape and form.' I have not time to stop here, and comment upon such palpable and dangerous doctrine. I have only to say, let the medical historian record this sentiment, maintained in the highest medical universities in America in the nineteenth century. I am pleased, however, to observe, that all physicians do not coincide with such views."
