The Five Elements, showing the Cycle of Creation (outer arrows),and the Cycle of Destruction (inner arrows).
Define the Five Elements and their associations
The 5 elements is a bit of a misnomer, it would be better called the 5 phases cycle, as the wu xing is often translated. The 5 elements -water, wood, fire, earth and metal each have a profound effect on one another, either creative or destructive, eg: water nurtures wood, wood nurtures fire, fire creates earth, earth creates metal metal condenses water – this is the creative cycle. The destructive cycle- wood penetrates and destroys earth, earth absorbs and destroys water, water puts out fire, fire melts metal, and metal chops wood.
In essence these elements are a study of relationships and influence in nature, and how they are reflected in the human body-they have a profound effect on health in that they are reflected in the various organ meridians(see my list above- elemental associations) and this cycle of nurturing or controlling(creating or destroying) is used in TCM
