This eruption usually commences with a brownish spot on some part of the head; which soon discharges matter so acrid as to excoriate the skin, and spreads so as sometimes to entirely cover the head. Children are particularly subject to this eruption, which is occasioned by improper diet, uncleanliness, or contagion.


It is necessary to administer two or three courses of medicine to cleanse the system from the impurities that occasion the eruption. First wash the head two or three times a day with castile soap, then a strong tea of meadow fern burs and leaves; after which apply a poultice composed of slippery elm, pond lily root, and barberry, using the composition tea internally to favor perspiration. Particular attention should be paid to diet, avoiding butter, tea or coffee.
