Cataplasmata. Poultices.

Poultices are thick pasty preparations usually intended to be made as required. Except in special cases, the boiling water is placed in a previously warmed basin, and the powder, or mixed powders, stirred in with a warm spoon until a mass of the proper consistence results. This is placed in a muslin bag and applied hot; the linen may be protected by covering the poultice with jaconet, oiled silk, or gutta percha tissue.

The British Pharmaceutical Codex, 1911, was published by direction of the Council of the Pharmaceutical Society of Great Britain.
