TCM Constitution Types (Ti Zhi): Understanding Your Body's Blueprint
Discover the 9 TCM constitution types (体质分类) developed by Professor Wang Qi. Learn which body type you have, what imbalances you're prone to, and personalized wellness strategies for each type.
What Are TCM Constitution Types?
Constitution (体质, Tǐ Zhì) in TCM refers to your body’s unique, relatively stable physical and psychological makeup — determined by both congenital (inherited) and acquired (lifestyle, diet, environment) factors. Your constitution influences which diseases you’re prone to, how you respond to stress, and what treatments work best for you.
In 2009, Professor Wang Qi (王琦) of Beijing University of Chinese Medicine officially standardized Nine Constitution Types, which have since been adopted by the Chinese government as part of TCM health management. This framework is considered a form of personalized preventive medicine — identifying risks before disease manifests.
Key principle: Your constitution is not your destiny. While you inherit a baseline tendency, diet, exercise, and lifestyle can modify your constitution over time. TCM aims to nudge your constitution toward balance.
