The basic energetic quality of Phlegma is cold and moist, (hence its association with the season of winter) a fact that the Hippocratic text On the Nature of Man encourages one to prove for oneself by simply touching phlegm and feeling its cool nature compared to blood or bile.
Galen had combined the Empedoclean notion of the basic constituents of the universe (earth, fire, water, air) with the Hippocratic assumption that human beings were composed of four humors--black bile (melancholia), blood (sanguis), yellow bile (choler), and phlegm (phlegma).
