Nine constitution types
TCM Body Constitution Test
A TCM body constitution assessment is a traditional framework for describing recurring tendencies across the nine constitution types used in modern Traditional Chinese Medicine education. Assessments may consider experiences and habits over time, but they are not medical diagnoses or replacements for professional care. Biohack.BaZi explores constitution through its existing BaZi-based experience rather than presenting this page as a questionnaire.
What Is TCM Body Constitution?
体质 (tǐ zhì), often translated as body constitution, describes an individual's relatively stable tendencies within a TCM framework. Modern assessments commonly draw on the nine-constitution model associated with TCM public health research. Context, season, age and life circumstances can all influence how a pattern appears.
What Are the 9 TCM Constitution Types?
| Traditional name | English name | Concise description |
|---|---|---|
| 平和质 | Balanced | A relatively even constitutional pattern; often described as steady energy and adaptable routines. |
| 气虚质 | Qi Deficiency | A traditional pattern framed around available qi and stamina; people may describe low reserves or needing more recovery. |
| 阳虚质 | Yang Deficiency | Associated in TCM language with warmth, activation and a preference for gentle consistency. |
| 阴虚质 | Yin Deficiency | A pattern discussed through restoration, moisture and the balance between activity and replenishment. |
| 痰湿质 | Phlegm-Dampness | A traditional model of sluggish transformation and heaviness; the language is symbolic, not diagnostic. |
| 湿热质 | Damp-Heat | A combined pattern of dampness and heat in TCM theory, often explored through habits and environment. |
| 血瘀质 | Blood Stasis | A traditional description of constrained movement and circulation within the TCM model. |
| 气郁质 | Qi Stagnation | A pattern concerned with the free movement of qi, mood and expression in traditional language. |
| 特禀质 | Special Constitution | A category for distinctive sensitivities and constitutional features outside the other groupings. |
How Does a TCM Constitution Assessment Work?
A questionnaire usually asks about a cluster of experiences over time, rather than one isolated symptom. A useful result shows which descriptions resonate, where uncertainty remains and what questions you might bring to a qualified practitioner.
Can Your Constitution Change?
Traditional texts and modern TCM practice describe constitution as both tendency and process. Sleep, stress, food, activity, environment and life stage may change how a pattern is expressed. That makes an assessment a snapshot for reflection, not a permanent label.
TCM Constitution vs Medical Diagnosis
A medical diagnosis uses modern clinical history, examination and validated tests to identify a condition. TCM constitution categories belong to a different explanatory system. They can be studied respectfully alongside modern healthcare, but one cannot stand in for the other.
