Objectives Because of growing interest in personalized medicine, constitutional medicine also becomes more important. Constitutional medicine has already developed in many countries. In this study, we tried to investigate five type personality (Wutairen), a kind of Chinese constitutional medicine. Methods We did a research on five type personality using CNKI (http://www.cnki.net) up to Jan 15, 2018. Total 204 papers were searched with the keyword "Wutairen". We excluded 170 papers away from the subject or clinically studied. As a result, 34 papers were selected and analyzed. Results and Conclusions Five type personality (Wutairen) originated from Huangdi Neijing-Lingshu. There are 5 types: greater Yin person (Taiyin), lesser Yin person (Shaoyin), greater Yang person (Taiyang), lesser Yang person (Shaoyang) and Yin-yang balanced person. These are classified according to Yin-Yang content. Each type has different characteristic, treatment and prevention. Five type personality theory considers internal factors more important than external factors. Also, it considers the balance of Yin-Yang important.
