Huang Huang's Ten Formula Family Constitutions

A framework matching ten key classical herbs — and the formula families built upon them — to stable constitutional types. Each type describes the person who most reliably responds to that family: their build, complexion, temperament, and vulnerabilities.

Family 01 · Yang Warm
桂枝
Guì Zhī — Cinnamon Twig
Surface disharmony — Wei Qi dysregulation and blood deficiency
Modern analogy: Dysautonomia · Postural instability · Cardiovascular and neurological sensitivity · Connective tissue vulnerability
Constitutional Person

Lean to medium build — notably not robust or heavily muscled. The Gui Zhi type is the most refined and delicate of the ten. Skin is pale or tends to flush easily, sometimes with a pinkish cast. Huang Huang describes the classical prototype as someone who looks fragile rather than sturdy — fine bone structure, light musculature, visible veins. Spontaneous sweating is a hallmark: the body leaks qi at the surface. Cold hands and feet are common. This person is easily fatigued and easily startled.

Palpitations and an awareness of the heartbeat are characteristic. Women of this type frequently have gynecological irregularity — cold uterus, difficult menstruation, postpartum conditions. The range of Gui Zhi formulas is wide precisely because this constitution underlies so many disorders: it is one of Huang Huang's most frequently applied types.

Physical Signature
Build

Lean to medium. Light musculature. Not the robust, oily-skinned Da Huang type — almost the opposite. Huang Huang uses the phrase "refined" or "delicate."

Complexion

Pale or slightly flushed. The skin may be thin, with a tendency to capillary visibility. Easily reddens with warmth or embarrassment.

Abdomen (Fukushin)

Soft, often slightly lax. May show a pulsatile quality in the epigastric region — the heartbeat visible at the abdomen. Abdominal tension is low rather than high.

Tongue / Pulse

Tongue pale, possibly thin coat. Pulse: floating and soft, or slightly rapid and thin. The surface does not hold the pulse firmly — it floats outward.

Key Formula Entries
Gui Zhi Tang 桂枝湯

The anchor formula. For the Gui Zhi constitution with fever, chills, and spontaneous sweating that does not resolve the exterior — the surface is open but not functioning. Huang Huang regards this as one of the most broadly applicable formulas in the classical tradition, extending far beyond acute cold to chronic autonomic dysfunction, postpartum weakness, and gastric disorders in the Gui Zhi type.

Core formula Spontaneous sweating Chills with fever Autonomic instability
Gui Zhi Jia Long Gu Mu Li Tang 桂枝加龍骨牡蠣湯

For the Gui Zhi type with significant spirit disturbance — palpitations, insomnia, anxiety, sexual dysfunction, hair loss. Long Gu and Mu Li anchor the floating yang and settle the spirit. Huang Huang applies this to a wide range of neuropsychiatric presentations in constitutionally lean, easily startled patients.

Palpitations Insomnia Anxiety Sexual depletion
Xiao Jian Zhong Tang 小建中湯

Gui Zhi Tang plus doubled Shao Yao and Yi Tang (malt sugar). For the Gui Zhi type with abdominal spasm and pain, fatigue, and underlying blood deficiency. Classical formulation for the constitutionally weak child with abdominal pain, but extends to adult presentations of deficiency with cramping and nervous exhaustion. Huang Huang considers this an essential formula for children.

Abdominal spasm Children Blood deficiency Chronic fatigue
Gui Zhi Fu Ling Wan 桂枝茯苓丸

For the Gui Zhi constitution with blood stasis — pelvic masses, ovarian cysts, uterine fibroids, dark or clotted menstruation. The underlying person remains lean and relatively deficient, but blood has become static. One of the most widely used formulas in Huang Huang's gynecological practice.

Gynecology Blood stasis Pelvic masses Menstrual disorders
Zhi Gan Cao Tang 炙甘草湯

For the Gui Zhi type with severe blood and yin deficiency — palpitations, irregular pulse, emaciation, dry skin, insomnia. This is the Gui Zhi formula for the most depleted end of the spectrum: the person is thin, the pulse irregular, the spirit floating. Huang Huang applies it to cardiac arrhythmias and post-illness exhaustion.

Arrhythmia Yin-blood deficiency Emaciation Irregular pulse
Dang Gui Si Ni Tang 當歸四逆湯

Gui Zhi Tang with Dang Gui, Xi Xin, and Tong Cao. For the Gui Zhi type with significant blood deficiency causing cold in the channels — cold extremities cold to the elbow and knee, chilblains, Raynaud's phenomenon, cold dysmenorrhea. The blood does not reach the periphery because it is insufficient, not because yang has collapsed.

Raynaud's phenomenon Cold extremities Chilblains Cold dysmenorrhea
Key distinction: The Gui Zhi type sweats spontaneously and is depleted at the surface. The Ma Huang type cannot sweat and is closed at the surface. Both are Taiyang — but the therapeutic direction is opposite.
Family 02 · Yang Warm
麻黃
Má Huáng — Ephedra
Exterior closure — surface locked, fluids unable to disperse
Modern analogy: Respiratory hyperreactivity · Tight-surface phenotype · Musculoskeletal density · Edema-prone constitution
Constitutional Person

Compact and muscular with tight, dense skin. Where the Gui Zhi type is lean and open-pored, the Ma Huang type is closed — the body does not give off its excess. Complexion tends toward dark yellow or slightly dull, not flushed. No spontaneous sweating; in fact the skin resists sweating even under stress or exercise. Huang Huang notes this person often has a strong physical presence without the fragility of the Gui Zhi type.

Respiratory disorders are the primary domain: asthma, bronchitis, and wheezing brought on by cold. The surface closure traps pathogen and fluid. Edema that is tense and not easily pitted is another hallmark. Musculoskeletal pain from cold-damp obstruction — joints that ache in cold weather, stiff neck and back — are common presentations.

Physical Signature
Build

Compact, muscular, dense. Skin is tight rather than open. Not obese — the flesh is firm. Body may look somewhat dense or heavy despite normal weight.

Complexion

Dull yellow or slightly dark. Not the florid redness of the Gypsum or Rhubarb type, nor the pallor of Gui Zhi. A "closed," muted tone.

Abdomen

Firm, not obviously distended. No significant hypochondriac tension. Key marker is skin and surface quality, not abdominal finding.

Tongue / Pulse

Tongue pale with thin white coat (cold type). Pulse floating and tight — the tightness reflects the locked exterior.

Key Formula Entries
Ma Huang Tang 麻黃湯

The core formula for exterior cold excess — the surface is locked, no sweating, strong chills, tight pulse. Huang Huang emphasizes this for robust patients who cannot sweat, noting it should be avoided in the elderly, those with hypertension, or the constitutionally deficient. The classical formula for the Ma Huang constitution facing an acute cold-type respiratory pathogen.

Core formula No sweating Tight pulse Cold pathogen locked exterior
Xiao Qing Long Tang 小青龍湯

For the Ma Huang type with cold-fluid accumulation in the lungs — thin, watery phlegm, coughing, wheezing, copious clear nasal discharge. The formula transforms cold-fluid (yin xie) rather than simply opening the surface. Huang Huang applies this frequently to allergic rhinitis, cold-type asthma, and chronic bronchitis in robust patients with cold pattern.

Cold asthma Thin watery phlegm Allergic rhinitis Chronic bronchitis
Ma Xing Shi Gan Tang 麻杏石甘湯

Ma Huang with Gypsum: opens the surface while clearing interior heat. For the Ma Huang type where heat has accumulated inside — wheezing with heat signs, sweating but wheezing, or post-febrile respiratory obstruction. The Gypsum cools the interior while the Ma Huang continues to open the lung. Huang Huang uses this for acute respiratory infections with both exterior obstruction and interior heat.

Wheezing with heat Post-febrile cough Pneumonia pattern
Ma Huang Fu Zi Xi Xin Tang 麻黃附子細辛湯

For the Ma Huang type with underlying yang deficiency — the surface is closed but the interior is cold as well. Exhaustion combined with inability to sweat; cold pathogen in a depleted patient. This formula bridges the Ma Huang (exterior) and Fu Zi (interior cold) constitution types. Huang Huang uses it for sinusitis, chronic rhinitis, and hypothyroid-pattern presentations where cold pervades both inside and out.

Exterior cold + interior yang deficiency Chronic sinusitis Exhaustion with cold obstruction
Yue Bi Jia Zhu Tang 越婢加朮湯

For the Ma Huang type with damp-heat edema — tense, non-pitting edema in a robust patient. The addition of Gypsum indicates interior heat, and Bai Zhu manages the dampness. Huang Huang applies this to nephrotic syndrome, acute nephritis with edema, and inflammatory musculoskeletal conditions with swelling.

Edema (tense, non-pitting) Nephritis Damp-heat joint swelling
Family 03 · Pivot Neutral
柴胡
Chái Hú — Bupleurum
Shaoyang dysregulation — pivot sensitivity, emotional-physical hypersensitivity
Modern analogy: HPA-axis instability · Neuroendocrine reactivity · Stress-sensitive regulatory type · The "tracking" patient
Constitutional Person

Medium to thin, with firm muscle tone — not soft or heavy. The most clinically distinctive marker described by Huang Huang: a blue-green cast to the skin, most visible at the temples and the yintang area between the brows. The skin is dry rather than oily. These patients are acutely sensitive — to temperature, to the emotional atmosphere of a room, to physical sensations others might not notice. They track their symptoms with unusual precision and detail.

Huang Huang notes that practitioners sometimes call these patients "hypochondriacal" — but this misreads them. Their sensations are real; they simply register environmental and internal change with exceptional fidelity. Appetite and libido are strongly affected by mood. Menstruation in women of this type tends to be difficult: irregular, cramping, premenstrual tension. This is one of Huang Huang's most extensively described constitution types, and he considers it one of the most prevalent in contemporary clinical practice.

Physical Signature
Build

Medium to thin. Firm rather than soft musculature. Tends toward cold extremities. Not overweight — distinct from the Ban Xia and Huang Qi types in this regard.

Complexion

Blue-green cast, especially at temples and yintang. Dry skin. Not the florid redness of excess types, nor the pallor of the coldest deficiency types.

Abdomen (Fukushin)

Key diagnostic: bilateral hypochondriac resistance and tenderness — even gentle pressure under the costal margins reveals tightness or discomfort. The most reliable objective confirmation of a Chai Hu constitution.

Tongue / Pulse

Tongue firm and slightly dusky — not pale and swollen. Pulse: wiry (xian). Tension is the defining quality — in the body, in the pulse, in the rib-side.

Key Formula Entries
Xiao Chai Hu Tang 小柴胡湯

The anchor formula for the Chai Hu constitution. Alternating chills and fever, bitter taste, dry throat, loss of appetite, hypochondriac fullness. Huang Huang extends this far beyond acute Shaoyang disease to chronic immune dysregulation, digestive-emotional overlap syndromes, autoimmune conditions, and any presentation with the classic alternating, shifting quality in a Chai Hu constitutional type. He calls this one of the most versatile formulas in the classical tradition.

Core formula Alternating symptoms Immune dysregulation Autoimmune Digestive-emotional overlap
Chai Hu Jia Long Gu Mu Li Tang 柴胡加龍骨牡蠣湯

For the Chai Hu constitution with significant neuropsychiatric involvement — anxiety, palpitations, insomnia, hypertension, emotional dysregulation. The additions of Long Gu and Mu Li anchor the ascending yang and settle the spirit. Huang Huang describes this as one of his most important formulas for contemporary practice, where the Chai Hu type's regulatory sensitivity has generated ongoing autonomic and spirit disturbance. Used in hypertension, panic disorder, stress-driven arrhythmia, and PTSD presentations.

Core formula Anxiety Hypertension Palpitations Panic disorder
Da Chai Hu Tang 大柴胡湯

For a more robust Chai Hu constitution with interior excess — the Shaoyang type who also has constipation, epigastric hardness and fullness, and excess heat signs. The addition of Rhubarb and Zhi Shi pushes toward the interior. Huang Huang uses this for hepatobiliary disorders (cholecystitis, gallstones), metabolic syndrome in the Chai Hu type, and stress-related hypertension with constipation.

Cholecystitis Constipation + rib-side fullness Metabolic syndrome Gallstones
Chai Hu Gui Zhi Gan Jiang Tang 柴胡桂枝乾薑湯

For the Chai Hu constitution with an underlying deficiency and cold — the sensitive, reactive patient who also has a cold abdomen, loose stool, and fatigue. This formula occupies a crucial bridging position between Shaoyang reactivity and Taiyin/deficiency cold. Huang Huang considers it important for the anxious, emotionally reactive patient who is also chronically depleted and cold at the core.

Shaoyang + cold deficiency Anxiety + loose stool Cold abdomen with stress overlay
Si Ni San 四逆散

For the Chai Hu constitution with qi constraint causing cold extremities and chest oppression — the liver qi stagnation archetype. The paradox of cold limbs from stagnation rather than from yang deficiency. Huang Huang uses this as a base for many modifications addressing the Chai Hu type's tendency toward emotional constraint manifesting as physical obstruction: irritable bowel syndrome, chest tightness, biliary spasm.

Liver qi stagnation Cold limbs from constraint IBS Biliary spasm
Chai Hu vs. Ban Xia: Both types can be emotionally sensitive, but the Chai Hu person is thin with dry skin and a blue-green cast; the Ban Xia person is overweight with a greasy tongue coat. Chai Hu dislikes being watched; Ban Xia likes the stage.
Family 04 · Yang Cold
石膏
Shí Gāo — Gypsum
Interior heat excess — metabolic fire without accumulation
Modern analogy: Inflammatory excess phenotype · High-metabolic constitution · Heat-generating, thirst-driven physiology
Constitutional Person

Robust and well-nourished with a strongly heat-generating constitution. The face is flushed, the complexion florid and reddish. Profuse sweating — not the leaking of the Gui Zhi type, but true heat-driven perspiration. Intense thirst and a preference for cold drinks. This person radiates warmth and tends toward inflammatory conditions. Voice is strong, appetite vigorous, energy high.

The key distinction from the Da Huang (Rhubarb) type: Gypsum addresses heat without dryness and accumulation. The Da Huang type tends toward constipation; the Gypsum type may sweat freely and remain otherwise unremarkable digestively. The heat is present but has not dried and compacted the bowel. Skin conditions, high fevers, inflammatory joint disease, and heat-type diabetes are common clinical presentations.

Physical Signature
Build

Robust to heavy build. Well-nourished, vigorous. Strong constitution with a high metabolic baseline. Not the tight-closed quality of Ma Huang — more overtly hot and open.

Complexion

Florid, reddish, flushed. Radiates heat. Profuse perspiration. Intense thirst with preference for cold beverages — a constant quality, not just acute.

Abdomen

Full but not hard. The interior heat has not compacted into the firm, hard abdomen of the Da Huang type. Warmth to the abdomen on palpation.

Tongue / Pulse

Tongue red, dry, possibly cracked, with yellow coat. Pulse: flooding (hong) and rapid — the classical four-bigs pulse (da mai). Flooding rather than forceful-deep.

Key Formula Entries
Bai Hu Tang 白虎湯

The flagship formula for the Gypsum type in heat excess — the four greats: high fever, profuse sweating, intense thirst, flooding rapid pulse. Huang Huang applies this in acute infectious diseases with high fever, inflammatory states, and what he calls the Yangming heat pattern in robust patients. The formula cools the interior without purging — appropriate when heat is present but bowel is not yet obstructed.

Core formula High fever Profuse sweating Intense thirst Flooding pulse
Bai Hu Jia Ren Shen Tang 白虎加人參湯

For the Gypsum type with significant fluid depletion from the heat — the thirst becomes extreme (drinking without satiation), and the patient is weakening. Ren Shen rebuilds the fluid and qi that the heat has consumed. Applied to diabetic thirst, heat exhaustion with collapse, and severe febrile states with fluid loss.

Extreme thirst (unquenchable) Diabetes Heat exhaustion Fluid depletion
Zhu Ye Shi Gao Tang 竹葉石膏湯

For the Gypsum type in convalescence — after a febrile illness, the heat has partially resolved but the patient remains feverish, thirsty, and depleted. The formula cools residual heat while tonifying the qi and yin that the fever has consumed. Huang Huang applies this to lingering low-grade fever after illness, radiation-induced heat in cancer patients, and exhaustion with low-grade inflammatory states.

Post-febrile convalescence Residual heat Cancer-related heat Lingering fever
Xiao Feng San 消風散

For the Gypsum type with wind-heat-damp skin conditions — intensely itchy, weeping, red rashes (eczema, urticaria, contact dermatitis). The heat constitution generates conditions at the skin surface; the formula clears wind and heat while resolving damp. Huang Huang uses this for inflammatory dermatological conditions in heat-type constitutions.

Eczema Urticaria Wind-heat skin conditions Intensely itchy rashes
Family 05 · Yang Cold
大黃
Dà Huáng — Rhubarb
Yangming accumulation — interior heat with dryness and stagnation
Modern analogy: Metabolic excess with stagnation · Cardiovascular risk phenotype · The "action hero" constitution
Constitutional Person

Big, muscular, and physically imposing. Huang Huang contrasts this type directly with the Gui Zhi person: these are the "rough, burly, heroic types" — not the refined, delicate Gui Zhi constitution. Reddish or swarthy skin tone with oiliness. A reddish or dark cast around the mouth. Strong appetite that is difficult to satisfy. The body retains and accumulates rather than dispersing. Constipation is characteristic — the bowel is sluggish or obstructed despite the strong intake.

This is the Yangming constitution ruled by the Stomach and Large Intestine. Big appetite, big build, excess heat. Clinically these patients commonly present with digestive complaints (GERD, bloating, constipation), headaches, dizziness, hypertension, or hyperlipidemia. A notable feature: sweating is limited to specific areas (forehead only, chest only, hands only) rather than generalized.

Physical Signature
Build

Big, robust, muscular, firm. Not soft and fluidy like the Huang Qi type. The musculature is solid, the frame large. The belly is firm and dome-shaped, not slumping to the sides.

Complexion

Reddish-swarthy, oily skin. Darkness or redness around the mouth. Not the florid flush of the Gypsum type — more of an oil and heat combined quality.

Abdomen (Fukushin)

Full, firm, and resistant. Does not droop or soften. Fullness and firmness that stays even when lying down. Lower abdomen may show resistance or tenderness on palpation.

Tongue / Pulse

Tongue red, firm, dark-colored; thick, dry coat. Like "steak left out in the fridge" — dark, tough, dry. Pulse deep and forceful, or rapid and full. Not the flooding quality of Gypsum — more sunken and dense.

Key Formula Entries
Da Cheng Qi Tang 大承氣湯

The most forceful purgative formula — for the Da Huang type with severe interior accumulation. Classical indication: constipation with abdominal hardness and distension, high fever, confusion, or mania in a robust patient. Huang Huang extends this to chronic metabolic accumulation, certain neurological excess states (stroke from excess, acute hypertensive crisis), and situations where strong downward purging is the therapeutic principle. Contraindicated in deficiency.

Core formula Severe constipation Abdominal hardness Excess neurological states
Tao He Cheng Qi Tang 桃核承氣湯

For the Da Huang constitution with blood stasis in the lower burner — the accumulation has thickened into static blood. Lower abdominal hardness and tenderness, possible manic or agitated behavior, dark menstruation or amenorrhea, evening fever. Huang Huang uses this for lower abdominal blood stasis syndromes, certain psychiatric presentations with blood stasis, and gynecological accumulation in the robust Da Huang type.

Blood stasis lower burner Amenorrhea Lower abdominal hardness Agitation with stasis
Da Huang Zhe Chong Wan 大黃蟅蟲丸

For the Da Huang type with chronic, deep blood stasis — the "dry blood" syndrome of chronic accumulation. Emaciation despite a history of robustness, dry and scaly skin, fixed and painful masses, amenorrhea. Huang Huang uses this for hepatic fibrosis, chronic abdominal masses, uterine fibroids in the Da Huang type, and what classical texts describe as chronic "five labors and seven damages."

Chronic blood stasis Hepatic fibrosis Dry skin + emaciation Abdominal masses
Yin Chen Hao Tang 茵陳蒿湯

For the Da Huang type with damp-heat jaundice — the accumulation has generated heat and damp in the liver and gallbladder. Bright yellow jaundice, dark urine, epigastric fullness, constipation. Huang Huang applies this to acute hepatitis, cholestatic jaundice, and biliary obstruction in constitutionally robust patients.

Damp-heat jaundice Hepatitis Cholestasis
Da Huang vs. Shi Gao: Both are excess, heat-type constitutions. The Gypsum type radiates heat with profuse sweating and flooding pulse — heat is dispersing outward. The Rhubarb type tends toward constipation, localized sweating, and a firm hard abdomen — heat is accumulating inward.
Family 06 · Yang Cold
黃連
Huáng Lián — Coptis
Stomach-heart heat — digestive fire disturbing the spirit
Modern analogy: Gastric inflammatory phenotype · Heat-driven insomnia and irritability · Upper digestive-nervous axis dysregulation
Constitutional Person

Irritable and easily angered — restlessness and hot temper are hallmarks. The heat in the Huang Lian type sits primarily in the Stomach, and from there it disturbs the Heart spirit: insomnia, palpitations, and a persistently active, overheating mind. These patients are often described as agitated or mentally congested — unable to clearly think or settle.

Digestively: epigastric focal distention, stomach aches, nausea, bad breath (from stomach heat, distinct from the bowel-constipation bad breath of the Da Huang type), and loose stool — not constipation. This is a key differential from Da Huang: the Huang Lian type has loose or urgent stool; the Da Huang type is constipated. The appetite may be heavy or poor, disrupted by the abdominal pain and bloating.

Physical Signature
Build

Moderate to robust. Less extreme than Da Huang — not always the large powerful type, but more excess than deficient. Heat signs are primary.

Complexion

Reddish or flushed, especially the face and chest. May appear to look "hot" even when not febrile. Eyes often slightly red or restless-looking.

Abdomen (Fukushin)

Epigastric focal distention and tenderness — the heat is centered at the middle. Not the firm lower abdominal resistance of Da Huang. The discomfort is more epigastric and burning.

Tongue / Pulse

Tongue red, especially the tip and center — heat in the Heart and Stomach. May have yellow greasy coat. Pulse rapid, possibly wiry. The tip redness is notable.

Key Formula Entries
Huang Lian Jie Du Tang 黃連解毒湯

For intense heat toxin affecting multiple systems — high fever, agitation, insomnia, bleeding from heat, skin eruptions. All four bitter cold herbs (Huang Lian, Huang Qin, Huang Bai, Zhi Zi) combine to clear heat from all three burners simultaneously. Huang Huang uses this for hypertensive crises, acute infectious disease with rampant heat, and the most extreme Huang Lian constitution presentations.

Core formula Heat toxin Hypertensive crisis Agitation + fever
Xie Xin Tang 瀉心湯

Three herbs (Huang Lian, Huang Qin, Da Huang) for epigastric distention and heat — the pivot formula between Huang Lian and Da Huang constitutions. Addresses heat accumulation in the middle burner with some degree of bowel obstruction. Huang Huang uses this for epistaxis and hematemesis from heat, esophageal reflux, and digestive inflammation with bleeding tendency.

Epigastric distention Heat bleeding (epistaxis, hematemesis) Reflux esophagitis
Huang Lian E Jiao Tang 黃連阿膠湯

For the Huang Lian type with yin deficiency — fire without root, heat that has consumed the yin. Intense insomnia, agitation, heart palpitations in a person who is also depleted and drying out. Huang Huang regards this as a key formula for the complex type where excess heat and yin deficiency are simultaneous — common in chronic anxiety disorders and what classical texts call "inability to sleep from heart-kidney disharmony."

Insomnia (severe) Heat + yin deficiency Heart-kidney disharmony Chronic anxiety
Zuo Jin Wan 左金丸

Six parts Huang Lian to one part Wu Zhu Yu — for the Huang Lian type with liver fire attacking the stomach. Acid regurgitation, burning epigastric pain, bitter taste, irritability. The small amount of warm Wu Zhu Yu prevents the extreme cold of Huang Lian from causing cold rebellion while directing the formula to the liver channel. Used for liver-fire gastritis, GERD, and biliary-gastric reflux.

Acid reflux Liver fire attacking stomach Burning epigastric pain GERD
Huang Lian vs. Da Huang: Both are heat types. The Huang Lian type has loose stool; the Da Huang type is constipated. The heat in Huang Lian sits in the Stomach and Heart, generating insomnia and agitation. The heat in Da Huang sits in the Intestines and generates dry accumulation.
Family 07 · Yin Hot
附子
Fù Zǐ — Aconite Accessory Root
Yang collapse — systemic cold from constitutional yang deficiency
Modern analogy: Adrenal-cardiac depletion phenotype · Hypothyroid-like presentation · Deep constitutional cold
Constitutional Person

Profoundly cold throughout — not a surface cold that warming resolves, but a constitutional cold that permeates the interior. Cold limbs extending beyond the wrists and ankles (the classical marker that distinguishes true yang deficiency from simple cold extremities from qi stagnation). Exhaustion that sleep does not restore. A dull, grey, or sunken complexion — the face lacks vitality and color. The patient's posture and movement are slow, careful, deliberate.

Huang Huang discusses the Fu Zi constitution with notable care — both because these patients need warming formulas powerfully applied, and because Aconite's toxicity demands attention to preparation and dosing. He notes a characteristic psychological quality: emotional blunting rather than simple sadness. These patients are not dramatically depressed — they are simply flat, withdrawn, slow to respond. Low blood pressure and bradycardia are common findings.

Physical Signature
Build

Often thin, drawn, and lacking vitality. The body looks cold — pallor, lack of tone, slow movement. May appear older than chronological age.

Complexion

Pale, grey, or dusky. No warmth or color. The face has a sunken quality — cheeks drawn, no flush. Dark rings under the eyes are common.

Abdomen (Fukushin)

Sunken and thin, cold to the touch. Soft with minimal tone. Palpable epigastric aortic pulsation sometimes present. The abdomen itself feels cold on the examiner's hand.

Tongue / Pulse

Tongue pale, swollen, with thick wet white coat. Pulse deep, weak, and faint — especially in the chi (kidney) position. Slow rate possible. The yang has retreated inward.

Key Formula Entries
Si Ni Tang 四逆湯

The core yang-rescue formula. Cold limbs beyond wrist and ankle, sunken weak pulse, exhaustion, diarrhea with undigested food, preference to lie curled up with aversion to cold. Huang Huang discusses this formula with great care: it is appropriate only for genuine yang collapse — not for simple cold sensitivity. Used for cardiovascular collapse, septic shock in the correct constitution, severe hypothyroid presentations, and chronic adrenal depletion.

Core formula Yang collapse Cold limbs beyond wrist/ankle Deep exhaustion Cardiovascular depletion
Zhen Wu Tang 真武湯

Yang deficiency with water accumulation — the body cannot transform fluids because yang is insufficient to drive metabolism. Edema (pitting, cold), dizziness, palpitations, cold limbs, loose stool, and urinary difficulty in a depleted, cold patient. Huang Huang applies this to heart failure, renal insufficiency, hypothyroid edema, and any pattern where fluid metabolism has broken down from yang deficiency. The water accumulates because the fire cannot move it.

Heart failure Cold pitting edema Renal insufficiency Hypothyroid edema
Fu Zi Xie Xin Tang 附子瀉心湯

An unusual combination: bitter cold herbs (Huang Lian, Huang Qin, Da Huang) with Fu Zi. For the complex patient who has simultaneous interior heat and exterior yang deficiency — hot epigastrium with cold limbs. The formulas addresses the paradox directly. Huang Huang uses this for the Fu Zi type who has developed a secondary heat pattern, or for complex mixed presentations in elderly or depleted patients with inflammatory signs.

Cold exterior + interior heat Complex mixed patterns Elderly with inflammatory signs
Fu Zi Tang 附子湯

For the Fu Zi type with bone and joint cold pain — cold permeating the musculoskeletal system, cold damp bi syndrome in a constitutionally yang-deficient patient. Body aches, cold and heavy joints, cold back, pale moist tongue. Huang Huang applies this to arthritis and fibromyalgia presentations in the cold-depleted constitution, where the pain is clearly cold in nature.

Cold bi syndrome Arthritis (cold type) Fibromyalgia (cold pattern) Cold back pain
Family 08 · Yin Warm
乾薑
Gān Jiāng — Dried Ginger
Middle burner cold — digestive yang deficiency with cold-fluid accumulation
Modern analogy: Hypometabolic digestive phenotype · Cold-type gut dysregulation · Watery, cold secretion pattern
Constitutional Person

A cold constitution centered specifically on the digestive system. Where the Fu Zi type has systemic, cardiovascular-level yang deficiency, the Gan Jiang type is cold primarily in the middle — the Spleen-Stomach axis has lost its warming fire. Nausea, vomiting, and watery cold secretions from the stomach are hallmarks. The secretions are thin, clear, and cold — not thick and phlegmy as in the Ban Xia type. The epigastric region feels cold to the patient and cold to the practitioner's hand.

Fatigue, poor appetite, and a preference for warm food and drink. These patients do very badly with cold, raw, or refrigerated foods. The complexion is pale and sallow. Importantly, the Gan Jiang type can overlap significantly with both the Fu Zi type (systemic cold) and the Ban Xia type (fluid accumulation with phlegm) — in practice, these formulas are often combined.

Physical Signature
Build

Often thin to medium, lacking vigor. Poor muscle tone. Low energy posture. Less constitutionally depleted than the Fu Zi type, but similarly low vitality.

Complexion

Pale or sallow — yellowish-white without warmth. The face reflects the cold in the middle. Not the grey sunken quality of Fu Zi — more dull and lacking color.

Abdomen (Fukushin)

Soft, possibly distended in the epigastric region. Audible water sounds (splash) on percussion or movement — cold-fluid accumulation in the stomach. Epigastric cold to the touch.

Tongue / Pulse

Tongue pale, wet, with thick white moist coat — the dampness of cold. Pulse deep, moderate, or slow. No heat signs anywhere.

Key Formula Entries
Li Zhong Wan 理中丸

The primary formula for warming and restoring the middle. Cold-damp Spleen patterns with loose stool, nausea, cold abdomen, and fatigue. Huang Huang notes this constitution does poorly with cold, raw foods and responds strongly to warmth. Ren Shen provides qi while Gan Jiang warms the cold. Extended to diarrhea, chronic gastritis (cold type), and abdominal cold pain. One of the most fundamental formulas in the Gan Jiang family.

Core formula Cold-damp diarrhea Nausea Cold abdomen Chronic cold gastritis
Da Jian Zhong Tang 大建中湯

For the Gan Jiang type with severe cold in the middle — visible peristalsis through the abdominal wall, intense cold cramping abdominal pain, vomiting, inability to eat. The formula is strongly warming with Shu Jiao (Sichuan pepper) and Ren Shen. Huang Huang uses this for severe cold-type intestinal obstruction patterns, post-surgical ileus in cold constitutions, and intestinal adhesions with cold cramping.

Severe cold abdominal pain Visible peristalsis Post-surgical ileus Cold intestinal obstruction
Gan Jiang Ling Zhu Tang 甘草乾薑茯苓白朮湯

(Licorice, Ginger, Poria, Atractylodes Decoction) For the Gan Jiang type with cold-damp affecting the lower back — cold, heavy lumbar pain that worsens in cold and damp weather, difficulty turning or rising. The cold-damp has settled into the kidneys and lumbar region. Huang Huang applies this to cold-type lumbar disc conditions, chronic lower back pain with cold-damp pattern, and what classical texts call "kidney착" (kidney cold-damp syndrome).

Cold-damp lumbar pain Heavy lower back Worsens in cold/damp
Gan Jiang vs. Fu Zi: Gan Jiang warms the middle (Spleen-Stomach); Fu Zi rescues the yang from the kidneys and heart. Gan Jiang cold is digestive cold — nausea, watery secretions. Fu Zi cold is systemic — cold limbs, cardiovascular depletion, deep faint pulse. They are commonly combined when both levels are involved.
Family 09 · Yin Warm
黃耆
Huáng Qí — Astragalus
Wei Qi deficiency — open pores, soft tissues, vulnerability to exterior
Modern analogy: Immunodeficiency phenotype · Hypotonic musculature · Autonomic surface dysregulation from deficiency
Constitutional Person

Overweight with characteristically poor muscle tone — the key distinction from the Ma Huang type, who is also solidly built but muscular and firm. The Huang Qi type's excess weight is soft and fluid: the belly is not a firm dome but slumps and spreads to the sides when lying down. The pores are too open — this person sweats easily without exertion, even in moderate temperatures. Wind sensitivity is marked: they dislike drafts and feel exposed in breezy conditions.

Frequent colds are typical — the Wei Qi that defends the surface is insufficient. Fatigue with low stamina. Huang Huang distinguishes this from the Gui Zhi type: both are surface-deficient, but the Gui Zhi type is lean and fine-boned while the Huang Qi type is overweight and soft-tissued. The Huang Qi type's core issue is deficiency of the tissue-nourishing, surface-defending qi — the flesh is abundant but lax, not vigorous.

Physical Signature
Build

Overweight but with soft, poorly-toned musculature. Fat slumps to the sides (not the firm dome of Da Huang). Skin is loose and soft. This is the "retired sumo wrestler" image — big but without firmness.

Complexion

Sallow, slightly puffy, pale or yellowish. The face looks soft and slightly edematous. Not the redness of the heat types. No vibrancy or color — muted, loose quality.

Abdomen (Fukushin)

Soft, lax, and possibly slightly edematous. No significant resistance. The tissue has low tone throughout. The abdominal wall itself is loose — not the taut wall of the Chai Hu or Da Huang type.

Tongue / Pulse

Tongue pale, possibly swollen and with tooth marks along the edges. Thin white coat. Pulse floating but weak — the surface is open (floating) but there is no force behind it (weak). Deficiency at the surface.

Key Formula Entries
Yu Ping Feng San 玉屏風散

The classic "jade windscreen" — for the Huang Qi type with recurrent colds from Wei Qi deficiency. Spontaneous sweating in the absence of disease, easy susceptibility to cold pathogens, fatigue. Huang Huang considers this the foundational formula for the Huang Qi constitution in its most basic presentation. Widely applied to recurrent upper respiratory infections, allergic rhinitis with deficiency pattern, and post-illness susceptibility.

Core formula Recurrent colds Spontaneous sweating Wei Qi deficiency Allergic rhinitis (deficiency)
Fang Ji Huang Qi Tang 防己黃耆湯

For the Huang Qi type with damp accumulation — the open-pored, soft-tissued constitution that has allowed pathological water to accumulate in the flesh. Edema of the lower limbs, heavy and swollen knees, soft puffy ankles, sweating easily. Huang Huang describes the patient of this formula with precision: overweight, low muscle tone, easy sweating, heavy legs. Applied to lower limb edema, knee joint effusion, and obesity with damp accumulation.

Lower limb edema Knee joint effusion Obesity with damp Sweating easily with heaviness
Bu Zhong Yi Qi Tang 補中益氣湯

For the Huang Qi type with qi sinking — fatigue, prolapse (of organs, uterus, rectum), shortness of breath on exertion, clear urine, loose stool. The qi has not only failed to defend the surface but has lost its upward-lifting function. Huang Huang uses this for organ prolapse, chronic fatigue syndrome, rectal prolapse, and post-surgical recovery in the Huang Qi constitution. One of Li Dong-Yuan's masterworks adapted for the Huang Qi type.

Bu Yang Huan Wu Tang 補陽還五湯

For the Huang Qi type with qi deficiency and blood stasis — specifically for hemiplegia, post-stroke sequelae, and peripheral neuropathy in the constitutionally deficient patient. Large doses of Huang Qi (up to 120g) move the blood through the channels by providing the qi to push it. Huang Huang applies this to stroke recovery, diabetic neuropathy, and chronic peripheral circulatory insufficiency in Huang Qi types.

A bridge between the Huang Qi and Gui Zhi constitutions — for the Huang Qi type with blood deficiency causing numbness and tingling of the limbs. Weakness, numbness, poor sensation. Huang Huang uses this for peripheral neuropathy with deficiency, post-chemotherapy neuropathy, and numbness in the overweight deficient patient.

Constitutional Person

Overweight with a big personality — Huang Huang notes that Ban Xia types are often performers, comfortable in front of crowds, fond of singing and speaking. This distinguishes them from the Chai Hu type, who is also emotionally sensitive but tends to withdraw from exposure. The Ban Xia type is large and outward-facing despite their sensitivity.

The defining physical features: a sallow or yellowish complexion and a greasy tongue coating. This greasy coat is the objective hallmark — it distinguishes the Ban Xia type from the Chai Hu type even when both are emotionally sensitive. Nausea is constitutional for this type: they lose their appetite easily, develop nausea under stress or in certain environments, and their digestive system is the first to register emotional disruption. Thick, abundant secretions (phlegm) are characteristic throughout — the body's fluids tend to congeal rather than flow clearly.

Physical Signature
Build

Overweight to heavy build. But unlike the Huang Qi type, the Ban Xia type can have moderate muscle tone — they are big rather than flabby. Big presence, big frame, big personality.

Complexion

Sallow, yellowish — the classic phlegm-damp complexion. Not the redness of heat types. A "murky" quality to the skin and face. Greasy appearance overall.

Abdomen (Fukushin)

Full, possibly with epigastric focal distention. Slippery quality on palpation in some cases. The phlegm accumulation tends to sit in the epigastric and upper abdominal regions.

Tongue / Pulse

Greasy tongue coat — the definitive marker. White or yellow greasy coat indicates phlegm-damp constitution. Tongue body may be swollen. Pulse slippery (hua) — the classical phlegm pulse.

Key Formula Entries
Ban Xia Xie Xin Tang 半夏瀉心湯

For the Ban Xia type with epigastric focal distention, nausea, vomiting, and borborygmus — the classic "heart-below congestion" pattern. A mix of cold (Huang Lian, Huang Qin) and warm (Gan Jiang, Ban Xia) herbs that simultaneously descends the turbid and restores the middle. Huang Huang uses this for functional dyspepsia, chronic gastritis, irritable bowel syndrome, and any presentation of epigastric congestion with alternating nausea and loose stool in the Ban Xia type.

Core formula Epigastric distention Nausea + loose stool Functional dyspepsia IBS
Wen Dan Tang 溫膽湯

For the Ban Xia type with phlegm-heat disturbing the spirit — insomnia, vivid dreams, anxiety, palpitations, dizziness, nausea, and a greasy yellow tongue. The phlegm has taken on heat and moves upward to disturb the mind. One of the most widely applicable formulas in contemporary practice. Huang Huang uses this for anxiety disorders, insomnia with vivid dreaming, post-traumatic stress, and any neuropsychiatric presentation in the phlegm-damp Ban Xia type.

Phlegm-heat insomnia Anxiety Vivid dreams PTSD Palpitations from phlegm
Ban Xia Hou Po Tang 半夏厚朴湯

For the Ban Xia type with qi-phlegm obstruction in the throat — the "plum-pit qi" sensation of something stuck that cannot be swallowed down or coughed up. Anxiety, depression, globus pharyngeus. The phlegm-qi has obstructed the passage between middle and upper. Huang Huang extends this to somatic symptoms of anxiety in the Ban Xia constitution, functional throat conditions, and vocal difficulties in the phlegm-damp type.

Globus pharyngeus "Plum-pit qi" Somatic anxiety Depression with phlegm
Ban Xia Bai Zhu Tian Ma Tang 半夏白朮天麻湯

For the Ban Xia type with phlegm obstructing the clear yang — vertigo, dizziness, heavy head, nausea, and headache in the phlegm-damp constitution. The phlegm prevents clear yang from ascending to the head. Huang Huang uses this for Ménière's disease, vestibular disorders, positional vertigo, and migraine with nausea in heavy, phlegm-damp patients.

Vertigo Ménière's disease Migraine with nausea Heavy head from phlegm
Da Ban Xia Tang 大半夏湯

For the Ban Xia type with severe vomiting from stomach deficiency — the stomach lacks the downward-moving function. Food is vomited after eating without significant force (regurgitation rather than projectile vomiting). Huang Huang uses this for gastroparesis, reflux with regurgitation, hiatal hernia presentations, and chronic vomiting in constitutionally deficient patients where the phlegm-damp has undermined the stomach's descending function.

Gastroparesis Chronic regurgitation Hiatal hernia Stomach deficiency vomiting
Ban Xia vs. Chai Hu: Both types can be emotionally sensitive. The key physical differentiators: Ban Xia is overweight with a greasy tongue coat and likes being on stage. Chai Hu is thin with dry skin, a blue-green tinge at the temples, and does not enjoy public exposure. Chai Hu's pulse is wiry; Ban Xia's is slippery.
