The theory of humours revisited
The Humoral Theory held sway for more than two thousand years, as it offered a rational and understandable model for the workings of the human body in both health and disease. It incorporated the concepts of the elements (fire, water, air, and earth) and the qualities (heat, coldness, moistness and dryness) which offered a viable explanation of both the microcosm (the body) and the microcosm (the environment). It also merged with the constructs related to the person’s temperament and lifestyle, and offered valuable clinical support in diagnosis, treatment, and recuperation.
