Sasang constitutional medicine

The Sasang typology (Hangul: 사상의학. Hanja: 四象醫學) is a classification scheme in Traditional Korean medicine. It was systematized by Lee Je-ma in his book Longevity and Life Preservation in Eastern Medicine (東醫壽世保元, 동의수세보원) in 1894. It divides people in four types based on their biopsychosocial traits: Tae-Yang ( 태양, 太陽) or "greater yang", So-Yang (소양, 小陽) or "lesser yang", Tae-Eum (태음, 太陰) or "greater yin", and So-Eum (소음, 小陰) or "lesser yin".

Each type consists of a classification of pathology, hygiene, medicine and hygiene depending on personality, psychological status and organ functionality. People consider that one cannot escape the category of biological body type, and the strengths and weaknesses of organs, both major and minor, depend on the type.

Donguibogam: Principles and Practice of Eastern Medicine is the representative standard of Eastern Medicine, and it treaties the relationship of "Nature vs. Man," and the Sasang typology focusses on "Man vs. Man," or Man's "Differences in Inner Consciousness."
