Pulvis Aloes Compositus. Lond. Compound Powder of Aloes

Both the active substances in these powders are ill adapted quite excluded. They should be then exposed to a temperature of not less than from 130 to 140 deg. of Fahrenheit's thermometer for three or four hours, or until the leaves begin to shrivel. They are then to be turned in the same temperature, and the heat kept up for six or eight hours longer, when the operation is generally finished; which is known by the leaves crumbling without much difficulty in the hand. If the process has been in all its parts properly managed, the result will be, that the leaves retain a beautiful green colour, and also in a high degree the medical properties of the plant to which they belong.

To preserve them in this desirable state, oil jars, made perfectly clean a nddry are found to answer best. Place the leaves lightly in the jars, and hermetically seal them. The filled jars ought to be in a dry and warm situation.
