Evacuantia

(From evacuo, to evacuate). Medicines suited to promote the discharge of fluids either by the secretaries, or in more artificial ways, as bleeding or blistering.

The latter discharge the fluids, or at least their proper portion, indiscriminately. The evacuants are errhines, sialagogues, expectorants, emetics, cathartics, diuretics, diaphoretics, and emmenagogues, q. v.

Evaporatio

(From evaporo, to evaporate). Evaporation, anathymiasis. The conversion of fluids, and sometimes even solids, into gaseous invisible fluid, probably into air. This process has been attributed to a solution of the fluid in air; but evaporation takes place in vacuo: even mercury exhales in the Toricellian vacuum, and ice in the open air. Water by evaporation seems to be decomposed; but the other phenomena have not yet been explained.

In pharmacy, some solid bodies are recovered from their state of solution by evaporation, by means of heat. This process is applicable to all those substances which are less volatile than the menstruum; as, solutions of alkaline salts, and the inodorous parts of vegetables and animals from water; resinous and odorous bodies from spirits of wine. The tincture of mint, for instance, made with spirit of wine, leaves a resin rich with the -properties of the herb on the evaporation of the spirit.
