Constitution-Based Formula Guide

What Is Body Constitution in TCM?

In Traditional Chinese Medicine, the concept of body constitution (体质, ti zhi) refers to the relatively stable set of physical, physiological, and psychological characteristics that define an individual's overall makeup. Constitution is shaped by both congenital factors — the essence inherited from one's parents — and acquired factors such as diet, lifestyle, environment, emotional habits, and age. It is not a disease state but rather a baseline tendency, much like a landscape that predisposes certain plants to thrive and others to struggle. Understanding your constitution helps you anticipate which types of imbalances you are most likely to develop and, correspondingly, which categories of formulas and dietary practices may support your wellness over the long term.

The standardized framework of nine constitutions was formally codified in the Chinese medicine standard Classification and Determination of Constitutions in Traditional Chinese Medicine (ZYYXH/T 157-2009), developed through decades of clinical research and population studies. This system identifies nine distinct types: balanced (平和), qi deficiency (气虚), yang deficiency (阳虚), yin deficiency (阴虚), phlegm-dampness (痰湿), damp-heat (湿热), blood stasis (血瘀), qi stagnation (气郁), and special or allergic constitution (特禀). While most people display a dominant type, it is common to have a mixed constitution blending features of two or three types. The nine-type system provides a practical map for connecting constitutional tendencies to appropriate formula categories.

It is important to emphasize that constitution-based formula selection is an educational framework, not a self-prescription guide. The formulas named below are classical prescriptions studied in TCM education for centuries. Whether a particular formula is appropriate for you depends not only on your constitution but also on your current pattern (zheng), the season, your age, any medications you take, and other individualized factors. A qualified TCM practitioner integrates all of these considerations. For a structured starting point, you may wish to try our Body Constitution Quiz.

The Nine Constitutions and Their Formula Categories

Each of the nine constitution types is associated with a family of classical formulas that address its characteristic tendencies. Below, we explore each type in detail, including its key signs, the corresponding formula category, representative classical formulas, and dietary recommendations.

1. Qi Deficiency Constitution (气虚质)

The qi deficiency constitution is characterized by insufficient life-force energy. People with this type often feel easily fatigued, have a soft or weak voice, breathe shallowly, and sweat with minimal exertion. They may be prone to colds and slow recovery from illness. The tongue is typically pale with teeth marks along the edges, and the pulse is weak. This constitution reflects an underlying weakness in the spleen and lung, the two organs most responsible for generating and circulating qi.

The corresponding formula category is tonifying qi formulas (补气剂). These formulas strengthen the spleen's transformative function and augment the lung's defensive capacity. Representative classical formulas include:

• Si Jun Zi Tang (Four Gentlemen Decoction) — the foundational qi-tonifying formula, containing ginseng, white atractylodes, poria, and licorice. It gently strengthens spleen qi and is the base from which many other tonifying formulas are derived.
• Bu Zhong Yi Qi Tang (Tonify the Middle and Augment the Qi Decoction) — developed by Li Dongyuan, this formula addresses spleen qi deficiency with sinking qi, manifesting as organ prolapse, chronic fatigue, and low-grade fever that worsens with exertion.

Dietary tips: Favor warm, easily digested foods such as congee, sweet potato, yam, and rice. Avoid raw, cold, and excessively greasy foods that burden the spleen. For practical food therapy, see our Qi-Boosting Foods Guide.

2. Yang Deficiency Constitution (阳虚质)

The yang deficiency constitution is marked by a lack of warming, activating energy. People with this type feel cold easily, especially in the hands, feet, and lower back. They may have a pale complexion, prefer hot drinks and warm environments, urinate frequently with clear urine, and have loose stools. The tongue is pale and swollen with a white, moist coating, and the pulse is deep and slow. This constitution often involves deficiency of kidney yang and spleen yang.

The corresponding formula category is warming yang formulas (温阳剂), which supplement the body's fire and dispel internal cold. Representative classical formulas include:

• Shen Qi Wan (Golden Cabinet Kidney Qi Pill, also called Jin Gui Shen Qi Wan) — the archetype of kidney yang tonifying formulas, containing rehmannia, dioscorea, cornus, hoelen, alisma, moutan, cinnamon, and aconite. It warms kidney yang and transforms fluids.
• Li Zhong Wan (Regulate the Middle Pill) — warms the middle jiao and strengthens spleen yang, used for cold-type digestive symptoms such as abdominal pain relieved by warmth, loose stools, and poor appetite.

Dietary tips: Include warming foods such as ginger, lamb, walnuts, leeks, and cinnamon. Limit cold-natured foods like watermelon, cucumber, and raw salads, especially in winter. Warming soups and stews are ideal. See our TCM Warming Spices Guide for more.

3. Yin Deficiency Constitution (阴虚质)

The yin deficiency constitution reflects insufficient cooling, moistening, and anchoring energy. People with this type tend to feel warm, especially in the palms, soles, and chest — the so-called "five-center heat." They may experience night sweats, a dry mouth and throat (especially at night), irritability, and a tendency toward constipation with dry stools. The tongue is red with little or no coating, and the pulse is thin and rapid. This constitution often involves kidney yin and liver yin deficiency.

The corresponding formula category is nourishing yin formulas (滋阴剂), which replenish fluids and clear empty heat. Representative classical formulas include:

• Liu Wei Di Huang Wan (Six-Ingredient Rehmannia Pill) — the classic kidney yin nourishing formula, containing rehmannia (prepared), dioscorea, cornus, hoelen, alisma, and moutan. It is the foundational prescription for kidney yin deficiency and the base formula for many yin-nourishing variations.
• Zuo Gui Wan (Restore the Left Pill) — a more concentrated yin-nourishing formula that also supplements kidney essence, used when yin deficiency is more severe or accompanied by essence depletion.

Dietary tips: Emphasize moistening, cooling foods such as pear, lily bulb, black sesame, duck, and tremella. Avoid excessively spicy, deep-fried, and warming foods that further deplete yin. See our Menopause Foods Guide for yin-nourishing dietary ideas.

4. Phlegm-Dampness Constitution (痰湿质)

The phlegm-dampness constitution is characterized by the accumulation of turbid dampness and phlegm in the body. People with this type tend to have a soft, fleshy physique, feel heavy and sluggish, and may be prone to oily skin, a greasy tongue coating, and a feeling of fullness in the chest or abdomen. They may sweat easily and feel sticky. The tongue is enlarged with a thick, greasy coating, and the pulse is slippery or wiry. This constitution is strongly associated with spleen weakness failing to transform fluids.

The corresponding formula category is transforming dampness and resolving phlegm formulas (化痰祛湿剂). These formulas dry dampness, transform phlegm, and restore the spleen's transport function. Representative classical formulas include:

• Er Chen Tang (Two-Cured Decoction) — the foundational phlegm-resolving formula, containing pinellia, tangerine peel, poria, and licorice. It transforms dampness, resolves phlegm, and regulates qi. Nearly all phlegm-treating formulas are modifications of this base.
• Ping Wei San (Calm the Stomach Powder) — dries dampness and harmonizes the stomach, used when dampness obstructs the middle jiao with symptoms of fullness, nausea, and reduced appetite.

Dietary tips: Favor dampness-resolving foods such as coix seed (yi yi ren), adzuki bean, winter melon, and tangerine peel. Reduce sweets, dairy, and greasy foods that promote phlegm formation. See our Dampness-Removing Foods Guide.

5. Damp-Heat Constitution (湿热质)

The damp-heat constitution combines the heaviness of dampness with the agitation of heat. People with this type often have a flushed or oily face, are prone to acne and skin eruptions, feel warm and sticky, and may experience bitter taste in the mouth, dark or scanty urine, and irritability. The tongue is red with a yellow, greasy coating, and the pulse is rapid and slippery or wiry. This constitution is common in humid climates and among those who consume alcohol and spicy, greasy foods.

The corresponding formula category is clearing heat and draining dampness formulas (清热利湿剂). Representative classical formulas include:

• Long Dan Xie Gan Tang (Gentian Longdan Decoction to Drain the Liver) — a powerful formula that drains damp-heat from the liver and gallbladder, used for symptoms such as bitter taste, red eyes, ear discharge, and genital itching or swelling.
• San Ren Tang (Three-Nut Decoction) — a gentler formula that clears damp-heat from the qi level, used for early-stage damp-heat patterns with chest oppression, fever, and heavy limbs.

Dietary tips: Include heat-clearing, damp-draining foods such as mung bean, bitter gourd, celery, green tea, and coix seed. Avoid alcohol, spicy food, lamb, and fried items. See our Summer Heat-Clearing Foods Guide.

6. Blood Stasis Constitution (血瘀质)

The blood stasis constitution is marked by sluggish or obstructed blood flow. People with this type may have a dull or darkish complexion, dark circles under the eyes, dry or rough skin, and a tendency toward fixed, stabbing pain. They may develop dark spots, easy bruising, or purple lips. The tongue is dark or purple, possibly with purple spots on the undersurface, and the pulse is choppy or wiry. This constitution is more common with aging and among those who are sedentary or experience chronic emotional stress.

The corresponding formula category is invigorating blood and dispelling stasis formulas (活血化瘀剂). Representative classical formulas include:

• Tao Hong Si Wu Tang (Four-Substance Decoction with Peach Kernel and Safflower) — a foundational blood-invigorating formula that combines the classic Si Wu Tang (four-substance decoction for nourishing blood) with peach kernel and safflower to dispel stasis. It both nourishes and moves blood.
• Xue Fu Zhu Yu Tang (Blood Mansion Stasis-Expelling Decoction) — addresses blood stasis in the chest and upper body, used for chronic pain, palpitations, and emotional distress related to stasis.

Dietary tips: Include blood-moving foods such as black fungus, hawthorn, safflower tea, and rose tea. Regular gentle movement and avoiding prolonged sitting are also important. See our Blood Circulation Foods Guide.

7. Qi Stagnation Constitution (气郁质)

The qi stagnation constitution is characterized by impaired free flow of qi, most commonly involving the liver's function of ensuring smooth emotional and energetic movement. People with this type are often emotionally sensitive, prone to sighing, mood swings, chest and hypochondrial tightness, and a feeling of a lump in the throat. The tongue may have thin coating with slightly purple edges, and the pulse is wiry. This constitution is strongly influenced by stress, emotional repression, and irregular routines.

The corresponding formula category is regulating qi and dispersing stagnation formulas (理气解郁剂). Representative classical formulas include:

• Xiao Yao San (Free and Easy Wanderer Powder) — the signature formula for liver qi stagnation with spleen deficiency. It soothes the liver, relieves depression, tonifies the spleen, and nourishes blood. It is one of the most widely used formulas in TCM for stress-related conditions.
• Chai Hu Shu Gan San (Bupleurum Powder to Spread the Liver) — focuses on soothing liver qi and relieving pain, used for chest and hypochondrial distension and pain, especially when spleen deficiency is less prominent.

Dietary tips: Include qi-moving foods such as citrus peel, radish, rose tea, and fennel. Practices that support emotional expression and gentle movement, such as tai chi and qigong, are especially beneficial.

8. Special or Allergic Constitution (特禀质)

The special constitution encompasses individuals with innate sensitivities, including allergic tendencies, asthma, eczema, and allergic rhinitis that often run in families. People with this type may react to pollen, dust, certain foods, or medications more strongly than others. The tongue and pulse vary depending on the current condition. This constitution reflects an underlying hypersensitivity of the body's defensive systems and a tendency toward disharmony between the interior and exterior.

The corresponding formula category is harmonizing and stabilizing formulas (调和固表剂), which regulate the relationship between the body's defensive (wei) qi and external factors. Representative classical formulas include:

• Yu Ping Feng San (Jade Windscreen Powder) — containing astragalus, white atractylodes, and saposhnikovia. It tonifies defensive qi, stabilizes the exterior, and prevents recurrent external invasions. It is widely used for allergic conditions and frequent colds.
• Xiao Feng San (Eliminate Wind Powder) — treats wind-related skin eruptions and allergies by dispersing wind, clearing heat, and resolving toxicity.

Dietary tips: Identify and avoid trigger foods. Emphasize mild, easy-to-digest foods that strengthen the spleen and stabilize the exterior. For allergic rhinitis specifically, see our TCM Allergic Rhinitis Guide.

9. Balanced Constitution (平和质)

The balanced constitution is the ideal state. People with this type have a moderate build, good appetite, restful sleep, stable emotions, and robust resistance to disease. Their complexion is bright, the tongue is normal pink with a thin white coating, and the pulse is calm and harmonious. They adapt well to seasonal and environmental changes. The balanced constitution does not require corrective formulas; instead, the focus is on maintenance and prevention — preserving the harmony that already exists.

For the balanced constitution, the formula category is maintenance and preventive tonification (调养预防). This is not about taking daily medicine but rather seasonal adjustment:

• Seasonal food therapy aligned with the five elements — nourishing the liver in spring, clearing heat in summer, moistening the lungs in autumn, and warming the kidneys in winter.
• Gentle preventive formulas such as seasonal congees or simple herbal teas that align with the current season, used briefly rather than long-term.
• Lifestyle practices such as meditation, tai chi, and regular sleep-wake routines to sustain balance.

How Constitution Influences Long-Term Wellness

Constitutional awareness is valuable not because it tells you exactly which formula to take, but because it illuminates the terrain of your body. A person with a phlegm-dampness constitution who understands this tendency can proactively choose dampness-resolving foods, engage in regular movement to prevent stagnation, and be alert to early signs of dampness accumulation — long before a pattern fully develops. Similarly, a person with a yin deficiency constitution can prioritize rest, avoid overexertion, and choose moistening foods during the dry autumn months. This proactive approach is the essence of TCM preventive medicine, which emphasizes maintaining balance rather than waiting for illness to declare itself.

Constitution can also shift over time. Aging tends to move constitutions toward deficiency, as kidney essence naturally declines. Major life events, chronic illness, or sustained dietary and lifestyle changes can alter your dominant type. This is why periodic reassessment — ideally with a qualified practitioner — is valuable. The goal is not to label yourself permanently but to use constitutional awareness as an ongoing tool for personalized wellness.

For those interested in a deeper understanding of the diagnostic frameworks that complement constitutional assessment, our Eight Principles Differentiation Guide and Organ Differentiation Guide provide the clinical vocabulary that practitioners use to refine formula selection beyond the constitutional level.

Integrating Constitution with Other TCM Frameworks

Constitution is one layer of the TCM diagnostic mosaic. When a practitioner evaluates a patient, they consider constitution as the background context, but they also assess the current pattern through multiple lenses: the Eight Principles (exterior/interior, cold/heat, deficiency/excess, yin/yang), organ differentiation (which zang-fu system is primarily affected), qi and blood differentiation (is there deficiency, stagnation, or rebellion), and the influence of the six pathogenic factors. Only by synthesizing all of these layers can a practitioner select a formula that is truly appropriate for the individual at that moment.

For example, a person with a yang deficiency constitution who presents with an acute wind-heat invasion (sore throat, fever, yellow pharyngeal congestion) would not be given a warming yang formula in the acute phase. The acute pattern takes priority, and a heat-clearing, exterior-releasing formula would be used first. Once the acute condition resolves, constitutional management with warming formulas and dietary adjustments would resume. This illustrates the principle that the pattern determines the immediate strategy, while the constitution guides long-term maintenance.
