Four Humours

Fringe medicine
The four major fluids in the body—yellow bile, phlegm, black bile and blood—which the Greeks believed corresponded to the four elements—fire, water, earth and air—in the universe. Now of historic interest, the Four Humours may be evoked or listed as part of a non-mainstream therapeutic philosophy or system that is not founded on currently accepted scientific principles.
