Cure for a Black Eye
Bathe it with tepid water, and then apply a piece of lint saturated with the pure extract of lead. Keep the lint continually wet with the lotion for two or three hours.

Bruises
The only treatment that does any good is to bathe the bruised part with cold water — the colder the better — to check the diffusion of blood through the tissues. The part should be kept as still as possible and not be rubbed. Applying a piece of raw meat to a black eye may not do any harm, but it certainly has no useful effect.

For a Black Eye
An excellent application for “black eye” is twenty drops of calendula (juice of marigold) to a teacupful of water, applied by means of a pad of lint. Calendula is a splendid substitute for arnica
in case of a bruise, where the skin is abraded, as in such a case the latter will often produce what is known as “arnica poison.”
