A Model for Dynamic Relationships
In Traditional Chinese Medicine (TCM), the theory of the Five Elements (Wu Xing) is not a static list, but a living model that describes how everything in nature – and therefore also in our bodies – is interconnected. The five elements are Wood, Fire, Earth, Metal and Water.
The Nourishing Cycle (Sheng)
This is the “Mother-Child” relationship. One element nourishes and generates the other.
Wood feeds Fire:Just as wood fuels a fire, in the body this means that the Liver (Wood) supports the Heart (Fire). Healthy Liver energy ensures a smooth blood flow to the Heart.
Earth nourishes Metal:Just as metals are mined from the earth, a strong Spleen (Earth) provides sufficient energy for the Lungs (Metal).
The Control Cycle (Ke)
This is the “Grandmother-Grandchild” relationship. One element restrains the other to maintain balance.
Water controls Fire:Water extinguishes fire. The Kidneys (Water) prevent the Heart (Fire) from overheating. If this control is lost, restlessness or insomnia can occur.
Wood Controls Earth:Roots hold the earth. The liver ensures a smooth flow of qi, which aids the spleen in digestion.
In practice:Health is a dance between nourishment and control. Complaints often arise not in the organ that’s bothering you, but in the element that’s under-nourishing or over-controlling.
