|BOOKS ON OLD MEDICAL TREATMENTS AND REMEDIES
HOME PHYSICIAN AND ENCYCLOPEDIA OF MEDICINE The biggy of the late 1800's. Clearly shows the massive inroads in medical science and the treatment of disease.
ALCOHOL AND THE HUMAN BODY In fact alcohol was known to be a poison, and considered quite dangerous. Something modern medicine now agrees with. This was known circa 1907. A very impressive scientific book on the subject.
DISEASES OF THE SKIN is a massive book on skin diseases from 1914. Don't be feint hearted though, it's loaded with photos that I found disturbing.

Definition.—Clavus, or corn, is a small, circumscribed, conic,
deep-seated, horny formation or callosity, usually seated about the toes,
with the small end of the growth pressing down upon the corium.
A corn resembles a callosity, the epidermis being thickened, pol
ished, and horny. It differs, however, from callosity in being smaller
and circumscribed, averaging a pea in size, and in being provided with
a central prolongation or horny peg, shaped like the head of a nail,
known as the core. The base of the corn is directed upward and the
apex downward, the latter by its pressure on the nerve filaments giving
rise to pain. Two varieties of clavus are recognized—the hard and the
soft. The former is the common one, and generally occurs on the dorsal
surface of the toes or on the plantar aspect of the foot; although they
may, however, appear on any other part which is subjected to pressure
or friction long continued. One, several, or more may be present. A
soft corn is generally seen between the toes; it is depressed in the center,
and of a grayish color, and, owing to the constant heat and moisture of
the parts, it becomes soft. Not infrequently, when improperly treated,
corns are the starting-point of erysipelas and suppuration, and even
ulceration may occur. From accidental causes or as the result of con
stant pressure or from some unknown factor a corn exceptionally be
comes the seat of inflammatory and suppurative action which may be
more or less persistent—suppurating corn. They are prone to become
quite sensitive during climatic changes, and are usually at all times
painful when pressed upon, and sometimes spontaneously so. On the
sole of the foot, when well developed, they may give rise to considerable
discomfort, making locomotion or standing painful; doubtless some of
these latter cases more properly belong under verruca plantaris (q. v.).
Etiology and Pathology.—A corn results from pressure
with counterpressure and friction, attributable generally to tight or
badly fitting shoes. It appears, however, that apparently similar
formations may occur spontaneously independently of pressure, as in
the cases of Davies-Colley, quoted by Crocker, in which the palms and
plantar surfaces of a Hindoo were the seat of numerous clavi. Primarily
the growth is, as in callositas, an attempt to protect a part pressed upon,
but its subsequent peculiar development is difficult to understand. It
consists of a circumscribed hyperplasia of the epidermis, of conic shape,
with the base external, variously elevated, and with the apex directed
downward and pressing upon the papillae. It is, in fact, a peculiarly
shaped callosity, the central portion and apex being dense and horny,
forming the so-called core. The corium beneath the down-pressing apex
is thinned, and the papillae are usually atrophied, although occasionally
hypertrophied. There is, Robinson states, more or less hypertrophy of
the papillae at the circumference. Unna noted “well-preserved condi
tion of the sweat-glands, and even those glands whose pores disappear
in the core do not atrophy.” Minute hemorrhages frequently occur
beneath the thickened epidermis, due to rupture of capillary vessels of
the papillae. Structurally, the growth is made up of closely packed
epidermic cells arranged in concentric layers.
Treatment.—Removal of the cause and the wearing of properly
fitting shoes are a sine qua non of successful treatment. In fact, if
pressure is removed, corns will in most instances disappear sponta
neously. In an affection so common, the plans of treatment recom
mended, as is to be expected, are almost innumerable. A simple and
popular method of treatment consists in shaving off, after a preliminary
hot-water soaking, the surface portion by means of a razor or sharp
knife, and then applying a ring of felt wadding or like material having
an adhesive side, to be found in the shops, over the region of the corn,
with the hollow part directly over the site of the core. This should
be worn for some time—usually several weeks—thus relieving the
growth of all pressure and friction; and if well carried out, this plan
quite frequently will bring a good result. Another method is to pare
off; as before, the thickened broad surface, and then carefully to dissect
out the core; in some instances, after thorough soaking and surface
removal, this can be extracted with the forceps. Chiropodists have
become quite expert in their removal, often dissecting them out without
previous softening, and with scarcely any pain and rarely any bleed
ing. In manipulations of this character it is absolutely imperative that
the instruments employed should be aseptic, as unpleasant complica
tions or consequences have occasionally been noted. In some cases
touching the base of the cavity left by the removal of the corn with a
droplet of a solution of caustic potash will prevent a return; but the
application must be made with care, and with a solution of not more
than 5 per cent, strength, and its action almost immediately neutralized
with vinegar or dilute acetic acid.
A safe and conservative plan, sometimes successful, consists in the
repeated application of a solution of salicylic acid in collodion, for which
the common formula is: Salicylic acid, gr. xxx-xl (2.-2.65); ext. cannabis
indica, gr. x (0.65); collodion and flexible collodion, ŕâ f5ij (8.).—M.
This is to be painted on the corn night and morning for several days,
at the end of which time the parts are soaked in hot water, and the horny
mass, or a greater part of it, will, as a rule, come readily away with a
little rubbing or scraping. If it is then at all tender, treatment is to be
discontinued for a few days, and the paintings resumed. Several repe
titions are usually necessary. After apparent relief the wearing of a ring-
pad, as already referred to, for a few weeks, is to be advised. Salicylic
acid has the peculiar property, especially when so applied, and also in
the form of a plaster, of softening and removing the horny layer of the
epidermis, and this drug is the active principle in most of the adver
tised corn-cures. The various caustics are also occasionally employed,
but their use requires care and caution. Of the milder caustics, lactic
acid may sometimes be applied, in minute quantity, with benefit, weak
ened or full strength.
In soft corns the same mild plans mentioned may also be employed.
Nitrate of silver is useful in these cases, the outer surface first being re
moved by salicylic acid or weak solution of caustic potash. The essen
tial measure is the prevention of friction and maceration by keeping the
toes slightly separated with a piece of soft lint or absorbent cotton,
changing frequently. When extremely sensitive, dilute lead-water is a
