Here are some brief aspects of each. Wood involves the aspects of germination, extension, softness and harmony. Fire involves heating and flaring. Earth involves the aspects of growing, nourishing, and changing. Metal is associated with cleaning up, killing, strength, and firmness.
Water is associated with cold, moisture, and downward flowing.
When one is affected, it affects another and they all have mutual generation. Wood generates fire, fire generates earth, earth generates metal, metal generates water, and water generates wood. The Zang-Fu theory explains the mutual relationships and pathological and physiological changes between the Zang organs and the Fu organs. There are five Zang organs and six Fu organs. The five Zang organs are the heart, lung, spleen, liver, and kidney's.
