A New National Standard for Body Constitution
In April 2026, China implemented its first national standard for TCM constitution classification. This landmark standard, developed by the National Administration of Traditional Chinese Medicine, officially recognizes nine body constitution types: one balanced type and eight imbalanced types. This replaces the era of guessing your constitution with a scientific framework for personalized health.
What Is Body Constitution?
Your constitution is not simply "deficient" or "overheated." It is a stable physical and mental state shaped by your innate endowment plus years of diet, sleep patterns, emotions, and environment. It determines which illnesses you are prone to, what foods suit or harm you, whether your wellness approach should focus on tonifying or clearing, and why the same regimen works for others but not for you.
The Nine Types in Detail
1. Balanced Constitution — The Health Benchmark
Well-proportioned body, abundant energy, rosy complexion, sound sleep, regular digestion, cheerful disposition, and strong immunity. If this describes you, simply maintain regular routines, balanced eating, and consistent exercise.
2. Qi-Deficient Constitution — Chronically Fatigued
Persistent fatigue, soft voice, spontaneous sweating, dizziness, poor immunity, and frequent colds. Nourish with millet, yam, pumpkin, chicken, mushrooms, and jujube dates. Avoid raw cold foods and overwork.
3. Yang-Deficient Constitution — Always Cold
Aversion to cold, cold hands and feet, preference for hot drinks, low spirits, and weak lower back. Warm with ginger, lamb, longan fruit, chives, and walnuts. Avoid icy drinks, raw foods, and staying up late.
4. Yin-Deficient Constitution — Dry and Hot
Dry mouth and throat, hot palms and soles, night sweating, red tongue with little coating, and constipation. Nourish with lily bulb, tremella, lotus seed, pear, ophiopogon, and black sesame. Avoid spicy barbecue, warming tonics, and late nights.
5. Phlegm-Dampness Constitution — Heavy and Sluggish
Overweight with a soft belly, chest congestion, heavy body sensation, oily face, and thick tongue coating. Clear with winter melon, coix seed, adzuki bean, white radish, lotus leaf, and tangerine peel. Avoid sweets, fried foods, and prolonged sitting.
6. Damp-Heat Constitution — Oily and Irritable
Oily face with acne, bitter taste in mouth, bad breath, yellow urine, and sticky bowel movements. Clear heat with mung bean, celery, bitter melon, purslane, lotus root, and poria. Avoid hot pot, barbecue, alcohol, and sugary foods.
7. Blood-Stasis Constitution — Poor Circulation
Dull complexion, dark spots, painful menstruation with clots, dark purple lips, and prominent purple veins under the tongue. Move blood with hawthorn, rose, peach kernel, black fungus, and angelica. Avoid raw cold foods and emotional suppression.
8. Qi-Stagnation Constitution — Depressed and Anxious
Low mood, excessive worry, chest tightness, frequent sighing, and anxiety-related insomnia. Smooth qi with finger citron, tangerine peel, cilantro, rose, and daylily. Prioritize social connection, meditation, and regular exercise.
9. Special Constitution — Allergic and Sensitive
Prone to allergies, asthma, skin rashes, and seasonal rhinitis. Eat mild, neutral foods and strictly avoid known allergens and irritants. Protect yourself from environmental triggers and pursue gentle, gradual strengthening.
Your Constitution Can Change
The national standard emphasizes that while constitution has relative stability, it is also markedly malleable. Late nights worsen yin and qi deficiency. Cold drinks worsen yang deficiency and phlegm-dampness. Sedentary habits with greasy food worsen damp-heat. Emotional repression worsens qi stagnation and blood stasis. In other words, your current constitution was largely shaped by your lifestyle — and it can be reshaped through daily adjustments.
Practical Guidance
Most people have a mixed constitution — common combinations include qi-deficiency with yang-deficiency, or phlegm-dampness with damp-heat. When multiple patterns co-exist, focus first on the most pronounced and most uncomfortable symptoms. Always identify your constitution before starting any wellness regimen — yang-deficient people eating cooling foods like tremella, or yin-deficient people eating heating foods like lamb, is reverse-wellness that does more harm than good.
