Akhlat: The Bodily Humors

Perhaps the best-known component of the theory of the seven naturals in Unani medicine is the concept of akhlat, or the four bodily humors. According to Unani concepts of physiological function there are three physical states of the human body: solid, liquid, and gaseous. The solid parts are the organs (azah), the liquid parts are the humors (akhlat) and the gaseous state is called pneuma (ruh).
