A recognisable pattern in modern clinical practice: the patient cannot fall asleep; when sleep finally comes, vivid or frightening dreams cause sudden waking; after waking, the heart races and it takes time to settle; during the day, the same patient is easily startled by sudden sounds or unexpected events, feels generally anxious, and experiences fatigue and poor concentration. This cluster — fear-fright-palpitation-insomnia-fatigue — is what TCM identifies as Heart-Gallbladder Qi deficiency with Heart-Spirit failing to consolidate (xin dan qi xu, xin shen shi shou). The formula designed for this pattern is An Shen Ding Zhi Wan (Calm the Spirit and Settle the Will Pill), developed from a Song Dynasty antecedent and definitively structured by Qing physician Cheng Zhongling (Cheng Guopeng) in Yi Xue Xin Wu. Cheng’s description remains precise after several centuries: "Those with internally deficient Yang Qi, Heart-Spirit failing to consolidate, with alarm and palpitation and inability to sleep — this is from Gallbladder Qi deficiency-Cold. Trembling as if someone is about to arrest them, nocturnal restlessness, dream-startling and frightened waking, Spirit-Soul insecure, even with sweating — all are evidence of Gallbladder deficiency. An Shen Ding Zhi Wan governs."
I. Historical Development and Wang Ang’s Annotation
An Shen Ding Zhi Wan’s earliest antecedent appears in Song Dynasty Yi Fang Lei Ju citing Jiu Yuan Fang; the classical formula structure was definitively established by Cheng Zhongling in Yi Xue Xin Wu with the addition of Zhu Sha (Cinnabar) as a coating. Wang Ang’s Yi Fang Ji Jie provided the formula’s most quoted annotation: "An Shen Ding Zhi Wan treats Heart-Gallbladder deficiency-timidity. Cheng Zhongling said: The Gallbladder is the Pure and Clear Organ; when it loses its normal state, it becomes timid and prone to fear. Ren Shen supplements the five viscera’ original Qi, strengthens the root of Gallbladder Qi; Long Chi and Zhu Sha sedate and consolidate the floating Spirit-Soul; Yuan Zhi and Chang Pu (Shi Chang Pu) awaken the mind’s obscuration; Fu Ling and Fu Shen guide Heart-Qi to return to the Kidney. When Gallbladder Qi is full, decision-making is restored; Spirit and Will are settled." This annotation captures the formula’s three-layer logic precisely.
The formula’s original composition included Zhu Sha (Cinnabar) as a pill coating. Modern clinical practice has largely discontinued Zhu Sha — it contains mercury and poses hepatorenal toxicity risk with sustained use. Common modern substitutes: Hu Po (Amber) 3–6g; Ci Shi (Magnetite) 20–30g (pre-decoct); or simply omit without replacement. This substitution does not significantly compromise the formula’s clinical efficacy when the remaining six herbs are appropriately dosed.
II. Six-Herb Composition and Three-Layer Analysis
Modern clinical reference doses: Ren Shen 10g · Fu Shen (Poria with wood) 15g · Fu Ling 15g · Yuan Zhi 10g · Shi Chang Pu 10g · Long Chi 20g (pre-decoct 30 min). Original classical method: grind to fine powder, refine into honey pills (as large as Firmiana seeds), with Zhu Sha as coating.
Layer 1: Supplement Qi to address the root — Ren Shen (Chief, paired with Long Chi)
- Ren Shen 10g (or Dang Shen 15g): greatly supplements original Qi; strengthens Spleen-Lung; calms Spirit. The formula’s root treatment: Heart-Gallbladder Qi deficiency means the Spirit lacks an adequate Qi substrate to remain consolidated; Ren Shen replenishes both Heart Qi and Gallbladder Qi, restoring the constitutional foundation for Spirit-stability. As Wang Ang noted: “supplements the five viscera’ original Qi, strengthens the root of Gallbladder Qi.” The Yi Xue Zhong Zhong Can Lu: “Ren Shen’s first action is calming the Spirit.” Use Hong Shen (red ginseng) or Bie Zhi Shen for severe deficiency; Dang Shen or Tai Zi Shen for mild deficiency or heat-sensitive patients.
Layer 1 (paired chief): Long Chi (Dragon tooth fossil) 20g (pre-decoct)
- Long Chi: sweet-astringent, cool; enters Heart, Liver. Heavy-settling, Spirit-calming, fright-settling, Yang-anchoring. Long Chi’s heavy mineral mass directly consolidates the floating Spirit, stopping the alarm-palpitation-fright-waking cycle at the branch level while Ren Shen addresses the root. The Yi Xue Zhong Zhong Can Lu: "Long Chi is an essential herb for settling the Spirit and fixing the Ambition (Po); it consolidates and astringes, collecting the wandering Yuan Qi and returning it to the Liver.” Must be crushed and pre-decocted for 30 minutes to extract its active mineral constituents. Long Chi is used in preference to Long Gu here as it has a somewhat stronger fright-settling and Spirit-calming action.
Layer 2: Strengthen Spleen and calm Heart — Fu Shen and Fu Ling (Deputy)
- Fu Shen 15g (Poria with pine root): sweet-bland, neutral; enters Heart, Spleen. Calms Heart and settles Spirit, strengthens Spleen and promotes urination. Fu Shen (the portion of Poria that grows around pine wood) has a stronger Heart-Spirit-calming action than ordinary Fu Ling. It directly reduces palpitations, insomnia, and nocturnal restlessness from Heart-Spirit agitation, while simultaneously protecting Spleen-Stomach from the formula’s heavy-settling herbs.
- Fu Ling 15g: sweet-bland, neutral; enters Spleen, Lung, Kidney. Promotes urination and percolates Damp, strengthens Spleen and harmonises Stomach, calms Heart. Paired with Fu Shen: one focuses on Heart-Spirit calming (Fu Shen), one focuses on Spleen-Damp elimination (Fu Ling). Together they prevent Phlegm-Damp from forming and further disturbing the Heart — the formula’s Phlegm-prevention component. Wang Ang: “guide Heart-Qi to return to the Kidney” — Fu Ling’s water-promotion action descends Qi from Heart to Kidney, normalising the Heart-Kidney Qi axis.
Layer 3: Open orifices and dissolve Phlegm — Yuan Zhi and Shi Chang Pu (Assistant)
- Yuan Zhi 10g: bitter-pungent, warm; enters Heart, Kidney, Lung. Calms Spirit and boosts intelligence, dissolves Phlegm and opens orifices, disperses swelling. Yuan Zhi’s distinctive action: it communicates between Heart and Kidney (“exchanges Heart and Kidney”), pulling the floating Spirit of the Heart down toward its Kidney-root and drawing Kidney-Water up to nourish the Heart. This dual upward-descending and downward-ascending quality is why it is paired with Shi Chang Pu. The Yi Zong Bi Du: "Yuan Zhi and Chang Pu open the obscuration, allowing Heart-Gallbladder Qi to communicate, so deficiency-timidity naturally calms.”
- Shi Chang Pu 10g: pungent-bitter, warm; enters Heart, Stomach. Opens orifices and awakens the Spirit, transforms Damp and harmonises the Stomach. Chang Pu’s aromatic-dispersing nature opens the Heart-orifice that has been obscured by Phlegm-Qi (the mechanism underlying anxiety-depression in TCM), allowing Spirit to flow freely. Paired with Yuan Zhi: both are warm-aromatic orifice-opening herbs; Yuan Zhi specifically opens from Heart to Kidney; Chang Pu opens the Heart orifice itself. Together they prevent the Phlegm-Qi obstruction that perpetuates the fright-anxiety cycle, and enhance drug absorption by keeping the Spleen-Stomach Qi mechanism free-flowing.
Three-layer formula logic:
① Supplement the root: Ren Shen fills Heart-Gallbladder Qi deficiency (the root cause of Spirit instability)
② Settle the branch: Long Chi directly consolidates floating Spirit and stops fright-palpitation
③ Remove the perpetuating factor: Fu Shen + Fu Ling prevent Phlegm-Damp from forming; Yuan Zhi + Chang Pu open the Heart-orifice and communicate Heart-Kidney, addressing the mechanism that prevents Spirit from settling
III. Pattern Identification — Heart-Gallbladder Qi Deficiency vs Other Spirit Disorders
Core pattern: Heart-Gallbladder Qi deficiency
Palpitations and alarm-fright; nocturnal restlessness with dream-startling and fright-waking; the characteristic sensation of “trembling as if someone is about to arrest them” (Cheng Zhongling’s formulation); daytime easy-fright and timidity; fatigue and poor concentration; poor appetite and pale complexion; pale tongue, thin white coating; thin-weak or wiry-thin pulse. Key discriminating feature: the deficiency character — no excess-Heat, no Phlegm-Fire, no prominent redness or agitation. Fear and fright predominate over restlessness and agitation.
| Pattern | Key features | Appropriate formula |
|---|---|---|
| Heart-Gallbladder Qi deficiency (this formula) | Fright-palpitation, timidity, fatigue; pale tongue; thin-weak pulse | An Shen Ding Zhi Wan |
| Liver-Blood deficiency with deficiency-Heat | Dry mouth, hot palms, exhaustion from overwork; red tongue; thin rapid pulse | Suan Zao Ren Tang |
| Phlegm-Fire disturbing Heart | Agitation, restlessness, bitter mouth; yellow greasy coating; slippery rapid pulse | Huang Lian Wen Dan Tang |
| Heart-Kidney non-interaction | Hot palms, night sweats, lumbar soreness; red tongue, little coating; rapid pulse | Tian Wang Bu Xin Dan |
IV. Clinical Applications and Case Examples
1. Insomnia (Heart-Gallbladder Qi deficiency type): difficulty falling asleep or staying asleep; frequent dream-frightened waking; heart pounding on waking; daytime easy-fright; fatigue; pale tongue; thin-weak pulse. No excess-Heat or Phlegm-Fire signs. Case example: 34-year-old woman, insomnia 8 years worsened by emotional trauma; wakes at 4–5am unable to return to sleep; palpitations on waking; anxious and easily startled; cold limbs; pale tongue, thin white coating with tooth marks; soft pulse. Given An Shen Ding Zhi Wan plus Huang Lian 6g, Chao Bai Shao 15g, He Huan Pi 20g, Fu Xiao Mai 30g. After 1 dose: slept 8 hours. After 7 doses: insomnia, palpitations, anxiety all improved. Continued with Chao Suan Zao Ren 15g added; further 5 doses for consolidation. Follow-up 2 months: stable 7h sleep, anxiety resolved.
Modifications: Qi deficiency severe → add Huang Qi, Bai Zhu; insomnia prominent → add Suan Zao Ren 15g, Ye Jiao Teng 15g.
2. Anxiety disorder (Heart-Gallbladder Qi deficiency type): emotional anxiety, timidity, easy-fright, palpitations; fatigue, poor concentration; pale tongue, thin-weak pulse. No prominent Phlegm-Fire or Liver-stagnation signs. Case example: 29-year-old woman, vivid nightmares and frequent waking for 6+ months; fright-waking with heart pounding and sweating; timid and easily startled; cold limbs; pale tongue; thin-weak pulse. Given An Shen Ding Zhi Wan combined with Gan Mai Da Zao Tang. After 7 doses: nightmares and anxiety markedly reduced; continued 14 doses, full resolution; stable at 1-month follow-up.
Modifications: Blood deficiency (pallor, dizziness) → add Dang Gui 10g, Long Yan Rou 15g; virtual Heat (oral bitterness, hand-palm heat) → add Huang Lian 6g; reduce Ren Shen dose.
3. Functional arrhythmia (palpitation, tachycardia, premature beats): Heart-Gallbladder Qi deficiency type: sinus tachycardia, functional premature beats with anxiety-fright trigger, fatigue, pale tongue, thin-weak pulse. Modifications: palpitations severe → add Suan Zao Ren 15g, Bai Zi Ren 12g, Mu Li 20g; Blood Stasis signs → add Dan Shen 15g.
4. Epilepsy (Heart-Gallbladder Qi deficiency with Phlegm): fright-triggered epilepsy or seizure disorder with the constitutional picture of Qi deficiency and Phlegm. Modifications: add Dan Nan Xing 6g, Zhu Ru 9g, Tian Ma 9g for Phlegm-type; increase Chang Pu to 15g.
Common modifications:
- Qi deficiency severe (extreme fatigue, breathlessness): add Huang Qi 15g, Bai Zhu 12g, Zhi Gan Cao 9g
- Fright-palpitation prominent: add Suan Zao Ren 15g, Bai Zi Ren 12g, Mu Li 20g (pre-decoct)
- Phlegm-turbidity (chest fullness, greasy coating): add Ban Xia 12g, Chen Pi 9g, Gua Lou 12g
- Deficiency-Heat component (oral bitterness, hot palms, red tongue tip): add Huang Lian 6g, Bai He 20g; reduce Ren Shen dose
- Blood deficiency (pallor, scanty menses): add Dang Gui 10g, Bai Shao 15g, Long Yan Rou 15g
- Epilepsy focus: add Dan Nan Xing 6g, Zhu Ru 9g, increase Chang Pu to 15g
V. Usage, Dosage, and Safety
Preparation: water decoction; Long Chi pre-decocted 30 minutes; take 2 doses daily (afternoon and 1 hour before sleep). Patent form: Hai Tian An Shen Ding Zhi granules (An Shen Ding Zhi Wan).
Zhu Sha (Cinnabar) note: original formula used Zhu Sha as pill coating (0.3–1g per dose). Modern practice: substitute with Hu Po 3–6g (dissolve into strained liquid separately) or Ci Shi 20–30g (pre-decoct), or omit entirely. Never use Zhu Sha for more than 7 consecutive days; avoid entirely in children, pregnant women, and patients with hepatorenal insufficiency due to mercury toxicity risk.
Contraindications: pregnant women (Shi Chang Pu and Yuan Zhi have mild stimulating properties; practitioner supervision required); breastfeeding women; allergy to any component; severe hepatorenal dysfunction; children (reduce doses under supervision); not for Phlegm-Fire disturbing Heart pattern (agitation, bitter mouth, yellow greasy coating — different mechanism requiring Phlegm-clearing formulas); not for excess-Fire insomnia.
Concurrent medications: do not combine with sedative-hypnotic drugs without physician guidance; avoid with Ren Shen antagonist herbs (Wu Ling Zhi, Li Lu — classical incompatibility); avoid strong tea, coffee, and alcohol during treatment.
Lifestyle co-treatment: regular sleep schedule (before 11pm essential); gentle daytime exercise (walking, Tai Chi, Ba Duan Jin) — moderate exercise supplements Qi and settles Spirit; emotional regulation (avoid excessive stimulation, horror media, loud environments); dietary support (millet congee, lotus seed, lily bulb, red dates, longan, yam for Spirit-nourishing).
