The local applications should consist of such substances as are gently escarotic, and which excite an action in the torpid vessels of the affected part. Arsenic, precipitate, and blue vitriol, have all been employed with success for this purpose. Dr. Griffitts informed me, that he has frequently accomplished the same thing in the Dispensary by applications of tartar emetic. They should all be used, if necessary, in succession to each other; for there is often the same idiosyncrasy in a sore leg to certain topical applications, that there is in the stomach to certain aliments. After the use of these remedies, astringents and tonics should be applied, such as an infusion of Peruvian, or white-oak bark; the water in which the smiths extinguish their irons, lime-water, bread dipped in a weak solution of green vitriol (so much commended by Dr. Underwood), compresses wetted with brandy, or ardent spirits of any kind, and, above all, the adhesive plasters formerly mentioned.
Tight bandages are likewise highly proper here. The laced stocking has been much used. It is made of strong coarse linen. Dr. Underwood gives several good reasons for preferring a flannel roller to the linen stocking. It sets easier on the leg, and yields to the swelling of the muscles in walking.
In scorbutic sores on the legs, navy surgeons have spoken in high terms of an application of a mixture of lime-juice and molasses. Mr. Gillespie commends the use of lime or lemon-juice alone, and ascribes many cures to it in the British navy during the late war, after every common application had been used to no purpose[66].
It is of the utmost consequence in the treatment of sore legs, to keep them clean, by frequent dressings and washings. The success of old women is oftener derived from their great attention to cleanliness, in the management of sore legs, than to any specifics they possess which are unknown to physicians.
When sore legs are kept from healing by affections of the bone, the treatment should be such as is recommended by practical writers on surgery.
I shall conclude this inquiry by four observations, which are naturally suggested by what has been delivered upon this disease.
1. If it has been proved that sore legs are connected with a morbid state of the whole system, is it not proper to inquire, whether many other diseases supposed to be local, are not in like manner connected with the whole system; and if sore legs have been cured by general remedies, is it not proper to use them more frequently in local diseases?
2. If there be two states of action in the arteries in sore legs, it becomes us to inquire, whether the same opposite states of action do not take place in many diseases in which they are not suspected. It would be easy to prove, that they exist in several other local diseases.
