Wood is the most human of the elements. It is the element of spring; the creative urge to achieve – which can turn to anger when frustrated. It is associated with the capacity to look forward, plan and make decisions.
Wood energy is rising, expanding, and is the force of growth and flexibility.
This element represents all the activities of the body that are self regulating and/or function without conscious thought; i.e. digestion, respiration, heart beat and basic metabolism.
The liver (which converts food into fuel which is then supplied to the muscles, tendons and ligaments) is associated to the Wood element.
