When the scrophulous suppuration ends in the ulcerative action, the cure is generally tedious. It is even doubted by some how far it is safe to attempt a speedy termination to the ulcer, as it is supposed, that, in this case, the disease may be driven to some other part: And so fearful are they of this dreadful event, that they are careful, by issues and new artificial sores, to continue the discharge after the original ulcer is healed.
If I have been right in my view of this disease, it will appear, that this reasoning is false, and that the practice is both useless and troublesome. Even those who propose and defend the practice, do so not upon the principles of reason and judgment, or from logical deductions from the theory which they give of the disease, but upon imaginary apprehensions. We find, for instance, Mr. Bell saying, that, “till the disease is eradicated from the habit, all that should in general be done to the sores, is, to give as free and open vent to the matter as possible[102].” From this, we should, without doubt, expect, that he considered scrophula as dependent upon some peculiar humour which was to be expelled; but just before we are told, that this disease depends upon debility, particularly of the lymphatic system; a condition which it is not customary to talk of eradicating, or rooting out, or expelling. Upon the common principles of reasoning, Mr. Bell ought only to have forbid healing the sores, until the system was strengthened, otherwise the weakness would be driven or determined to some other part.
Moderate pressure, by means of adhesive plaster, conjoined with the application of cold water, is one of the best remedies for the mild scrophulous ulcer, when it is situated so, that this can be used. When it is not, then dusting the part thickly with cerussa, containing a sixth part of powdered alum, may be had recourse to. A piece of dry lint is next to be applied, and a compress bound down, with such pressure as can be used. It is sometimes useful to dip the compress in cold water, and renew it frequently.
The ceratum e lapide calaminari forms a very good dressing for this sore, when it is intended to leave it to follow its own course.
As a stimulant, the unguentum resinorum, either alone, or mixed with red precipitate, is often used; but it seldom is of service, and often makes the sore irritable. If, however, the ulcer become very indolent, this, or the citrine ointment, properly diluted[103], may be of service. The same may be said of the other common stimulating applications.
Poultices made of bread and sea water have been recommended, but seem to possess little power of accelerating the cure.
Solutions of alum, of blue vitriol, corrosive sublimate[104], of the nitrites of copper, bismuth, and silver, are sometimes useful to wash the sore with.
The recent leaves of the wood sorrel bruised, and applied raw to the sore, is sometimes useful. The same may be said of cloths dipped in lemon juice, or vinegar and water.
Saturnine ointment is much employed by some, for abating heat and pain; but is inferior to compresses dipped in cold water.
