THE FOUR HUMORS
Humoral theory, a pseudo-science, is one approach to understanding traits and sickness. The four humors were once considered the core fluid constituents of the human body. Together, these fluids- blood, yellow bile, phlegm, and black bile- mediated the balance and universal health of a person in a process known as coction. The predominance of one humor over all others manifested in an imbalance of the body and mind, leading to ailments, afflictions, and temperamental behavior.
