Aræotics, in pre-modern medicine, were remedies believed to open up the pores of the skin, rendering them large enough for diseased matter to be carried off by sweat or perspiration . Such treatments were also believed to rarefy the humours, rendering them easy to be carried off by the pores.

To the class of aræotics belonged diaphoretics, sudorifics, etc.
