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.”
