Theory of Five Elements
Yang Health Center
Similar to the theory of yin-yang, the theory of five elements – wood, fire, earth, metal and water
– was an ancient philosophical concept used to explain the composition and phenomena of the
physical universe. In traditional Chinese medicine the theory of five elements is used to interpret
the relationship between the physiology and pathology of the human body and the natural
environment. According to the theory, the five elements are in constant move and change, and
the interdependence and mutual restraint of the five elements explain the complex connection
between material objects as well as the unity between the human body and the natural world.

In traditional Chinese medicine, the visceral organs, as well as other organs and tissues, have
similar properties to the five elements; they interact physiologically and pathologically as the five
elements do. Through similarity comparison, different phenomena are attributed to the
categories of the five elements. Based on the characteristics, forms, and functions of different
phenomena, the complex links between physiology and pathology as well as the interconnection
between the human body and the natural world are explained.

The five elements emerged from an observation of the various groups of dynamic processes,
functions and characteristics observed in the natural world. The aspects involved in each of the
five elements are follows:

Fire: draught, heat, flaring, ascendance, movement, etc.
Wood: germination, extension, softness, harmony, flexibility, etc.
Metal: strength, firmness, killing, cutting, cleaning up, etc.
Earth: growing, changing, nourishing, producing, etc.
Water: moisture, cold, descending, flowing, etc.

The order of mutual promoting among the five elements is that wood promotes fire, fire promotes
earth, earth promotes metal, metal promotes water, and promotes generates wood. In this way
each of the five elements has this type of mutual promoting relationship with the other, thus
promoting is circular and endless. According to the order of mutual restraining, however, wood
restrains earth, metal restrains wood, etc. Each of the five elements also shares this restraining
relationship with the other. Mutual promoting and mutual restraining are two aspects that cannot
be separated. If there is no promoting, then there is no birth and growth. If there is no restraining,
then there is no change and development for maintaining normal harmonious relations. Thus the
movement and change of all things exists through their mutual promoting and restraining
relationships. These relationships are the basis of the circulation of natural elements.
Encroaching and violating are the pathological conditions of the normal mutual promoting and
restraining relationships. Encroaching denotes that the restraining of one of the five elements to
another surpasses the normal level, while violating means that one of the five elements restrains
the other opposite to the normal mutual restraining order.
