The theory of Five Elements, also known as Wu Xing （五行） in Chinese medicine, is a fundamental concept that seeks to understand the dynamic interplay and relationships between various aspects of the natural world. It suggests that wood, fire, earth, metal, and water are not just physical substances, but also represent energetic qualities and principles that shape the material world.

Wood represents the energy of growth, expansion, and vitality. It is associated with the season of spring, the colour green, and the direction of east. Wood is also linked to the liver and gallbladder organs in the body.

Fire represents the energy of warmth, transformation, and enthusiasm. It is associated with the season of summer, the colour red, and the direction of south. Fire is linked to the heart, small intestine, pericardium, and triple burner organs.

Earth represents the energy of stability, nourishment, and grounding. It is associated with the season of late summer or transition periods, the colour yellow, and the central direction. Earth is linked to the spleen and stomach organs.
Metal (金 Jin)
Metal represents the energy of clarity, precision, and contraction. It is associated with the season of autumn, the colour white, and the direction of west. Metal is linked to the lungs and large intestine organs.
Water (水 Shui)
Water represents the energy of fluidity, adaptability, and conservation. It is associated with the season of winter, the colour blue or black, and the direction of north. Water is linked to the kidneys and urinary bladder organs.
In the theory of Five Elements, these elements are not viewed as static entities, but rather as dynamic forces that interact with and influence each other. The relationships between the elements are categorised into two main cycles: the generating cycle and the restraining cycle.
Wood generates Fire, Fire generates Earth, Earth generates Metal, Metal generates Water, and Water generates Wood. This cycle describes how each element supports and nourishes the next in a continuous flow of energy.
Wood restrains Earth, Earth restrains Water, Water restrains Fire, Fire restrains Metal, and Metal restrains Wood. This cycle illustrates how each element has the ability to control or restrain another element to maintain balance and prevent excessive energy.
The theory of Five Elements is utilised in traditional Chinese medicine for diagnosis, treatment, and understanding the interconnections between various aspects of health and well-being. It provides a framework to analyse and address imbalances in the body’s energy system and guide the use of acupuncture, herbal medicine, dietary adjustments, and lifestyle recommendations to restore harmony and promote optimal health.
