Chilblains

Chilblains are the result of too rapid warming of cold parts, generally feet or fingers. Sometimes for years after being frost-bitten, exposure to severe cold will produce itching and burning, and perhaps swelling and ulcers.

Treatment:

Rub with turpentine or alcohol. The rubbing in itself is excellent. See doctor.

The Burning of Sponge, Burnt Sponge

Cut the sponge in pieces, and bruise it, so as to free it from small stones; burn it in a close iron vessel, until it becomes black and friable; afterwards reduce it to a very fine powder.

This medicine has been in use for a considerable time, and employed against scrofulous disorders and cutaneous foulnesses, in doses of a scruple and upwards. Its virtues probably depend on the presence of a little alkali. It also contains charcoal; and its use may be entirely superseded by these substances, which may be obtained in other manners, at a much cheaper rate.
