Some physicians, who have abandoned the other resins and gums, as useless or hurtful in hectic complaints, still adhere to myrrh as a beneficial medicine; but from what I can learn, the cases in which this gum has been thought serviceable, are hectic complaints, from debility, in consequence of excessive evacuations of various kinds, and not proceeding from ulcerated lungs. After it is fully established that myrrh is of use in such instances, it will still be worthy of investigation, whether it is of more or less than Jesuits bark. I have repeatedly mentioned blood-letting, and a spare, diluting regimen, as the most powerful means of preventing and curing all affections of the lungs that depend on inflammation. In the case of external wounds, or bruises of the lungs, this method facilitates the immediate cure by the first intention. It is the chief thing to be depended on for the cure of pleurisies; and it is often owing to a neglect, or too sparing an use of this evacuation, that the complaint terminates in an abscess. In people predisposed by the form of their bodies, or the nature of their constitutions, to a spitting of blood, it may prevent the turgid vessels from bursting; and in those who have tubercles in the lungs, it is of the greatest utility, by preventing those tumours from inflaming, and becoming ulcers; but after the ulcers are actually formed, I have great doubts with regard to the propriety of attempting a cure by repeated bleedings, even in small quantities. This method has been often tried; but I fear the success with which it has been attended, gives no encouragement to continue the practice. That symptoms may be such, in every period of this disease, as to require this evacuation, is not to be denied; but there is a great difference in the application of what is considered as an occasional palliative, and that from which we expect a radical cure. In the one case, it will only be used when some particular symptom strongly urges; in the other, it will be used at stated intervals, whether the symptoms press or not; and may tend to weaken the already debilitated patient, without our having the consolation of knowing, with certainty, that it has had any other effect. Blisters do not weaken so much; they are of undoubted use in pleurisies; perhaps, by exciting external inflammation, they may contribute to draw off the inflammatory disposition within the breast: perhaps—But in whatever way they act, I imagine I have frequently seen blisters and setons, particularly the latter, of considerable service, even after the symptoms indicated the existence of an ulcer in the lungs.
