The seven element theory included all elements on earth: plants, warm energy, soil, mineral, water, cold energy, and air. This theory introduced each element's material, property, characteristics, function, relationship to each other, and relationship with life and organs. This theory tried to discover the universe's warm, dry, cold, and moisture energy, how they transfer and transform from the seven elements, and how they affect the animal and human life. The basic properties are good, bad, warm, dry, cold, and moist. Each element can have multiple properties. The property is associated with the amount and degree difference. The relationship of the seven elements is singular and mutual for promotion, restriction, over restriction and reverse restriction, excess and deficiency conditions, the mother and child relationship, and the classification and purpose of restriction. The relationship is about one element's interconnection to the other six in regards to these single and mutual conditions. The properties and relationships of the seven elements will reflect life and organ properties and relationships with the seven elements. The most important concept of the seven element theory is to provide a foundation of the relationship of organs with nature, and to set up principles and remedies for healthcare practices. The seven element theory is in accordance to each element's real property, function, and characteristics for connecting with life and organ functions. The main point is that the seven elements create life, and as life is created by Mother Nature, the seven elements are Mother Nature. One organ can represent one element, and characteristics of multiple elements can be contained in one organ. Multiple organs can have one element's property and functions. The main study methods are comparison, analysis, generalization, deduction, testing, and proving and disproving. This includes the categorization of things found in nature according to the attributes of the seven elements, such as shape, characteristic, property and function, followed by making the connection between things in nature and animal or human life. The original five elements theory is incomplete, the incomplete description of nature is not a universal truth. Only the universal truth will help us find life truth, and life truth will lead and guide us in how to deal with health conditions or issues.
