Camomile flowers, boiled in milk, and then expressed, yield a decoction, which, when made into a poultice with crumb of bread, frequently abates the pain. Sometimes the application of cloths, dipped in fine oil, give relief.

These sores are also frequently reduced to a more healthy state, by applying cloths dipped in the following mixture:

R. Ammon. Hepatizatæ[63] guttas decem.
Aq. Font. uncias octo.

This produces a moderate degree of smarting for a little time, during which the former painful sensation arising from the sore lessens, and does not return for some time. When the peculiar pain of the ulcer again manifests itself, the solution is again to be applied.

An ointment, consisting of two drachms of powdered opium, and one ounce of simple cerate, is also a very useful application.

Sprinkling the sore with red precipitate, or touching the surface with caustic, frequently stops the disease.

The kind of erythematous affection, which frequently affects the surrounding skin, is best removed by stimulating applications, which abate the pain or hot sensation, and make it less apt to ulcerate. The following is a very useful application for this purpose. The affected part is to be lightly dusted with it occasionally:

R. Hyd. Precip. Rub. unc. i.
Pulv. Opii semiunc.
Cretæ Ppt. unc. ii. Tere simul ut fiat pulvis subtiliss.
