So Eum Type

According to <Dong Eu Su Se Bowon Sadan theory in Korean traditional medicine>, “There are four different types of human as men born with different size in organs, larger/stronger Lung and Smaller/weaker Liver called TaiYang (TY) type person, Larger Liver and Smaller Lung called TaiEum (TE) type person, Larger Spleen with smaller Kidney called SoYang (SY) type, and Larger Kidney with smaller spleen called SoEum (SE) type person.”

Size differences of organs are the sign of diversification of Eum and Yang, and Universal transition; everybody is belonging to one of the 4types of TY, TE, SY, and SE. This theory is backed by <DongEuSuSeBowon Sadan theory>. According to this book, “size differences of Zang-Fu organs are already fixed by diversification of Eum Yang and temperament, so human-being is life is depending on the natural disposition that controls quality and length of life.”

The Four Type Human Factors Theory in Cosmetic Train theory classifies 4types as TY, TE, SY, and SE types. However, TY type is very rare in the population (about 1%), and clinical research is not enough to explain this type in detail, thus, TE, SY, and SE will be mostly applied in clinical research.

These three types divided into 6 types in Cold and Heat principles, and this difference is the most important diagnostic tool to check Weakness on the Face and Body, to check the Nutritional influence in the body including Energy, Blood, and Body Fluid.

Differentiate Disposition is the most crucial point of Verifying body type, and disposition does not only refer to characteristics but also refers to the tendency and temperament of humans.

The Four Type Human Factors are especially important in that they are clues to understand the tendency and temperament of the patient, and to predict and planning treatment terms for the patient. Also, these factors are important to teach patients to avoid aspects that could damage their health within daily lifestyle, and understand the aging process of the individual patient.
