PLASTERS, POULTICES AND STUPES
Moist heat, in the form of plasters, poultices, and stupes, is more penetrating than dry heat, and is often employed in cases of severe inflammation.
Mustard plasters are in such common use that it seems unnecessary to mention their value as counter-irritants.
To Make a Mustard Plaster.—For an adult, mix together in the proportion of 1 tbsp. mustard and 3 or 4 tbsp. flour, and rub into a smooth paste with warm water—not hot or cold water.
For a child, use from 4 to 6 tbsp. flour to ½ tbsp. mustard.
Spread the paste on muslin, turning each edge over about an inch. Cover with gauze or a piece of thin muslin.
To prevent blistering, it is well to add beaten white of egg in making the plaster, and to anoint the skin with vaseline or olive oil before applying the plaster.
