Gui Pi Tang (Restore the Spleen Decoction) is one of the most clinically versatile classical formulas in the TCM Heart-Spleen treatment category. Originally recorded in Song dynasty physician Yan Yonghe’s Ji Sheng Fang (Formulas for Rescuing Lives, 1253), it was later refined by Ming dynasty physician Xue Ji and has remained in continuous clinical use across nearly eight centuries. It is the standard representative formula for Heart-Spleen dual deficiency (xin pi liang xu) — the pattern in which excessive mental taxation depletes both the Spleen’s Blood-generating capacity and the Heart’s Blood-storing function simultaneously. Modern relevance: in an era of high work pressure, chronic sleep disruption, and habitual over-thinking, Heart-Spleen deficiency is one of the most prevalent constitutional patterns encountered in clinical practice. Gui Pi Tang remains the first-line formula for this presentation.

I. Source, Origin and Historical Development

Primary source: Ji Sheng Fang (Yan Yonghe, Song dynasty, 1253), original name “Ji Sheng Gui Pi Tang.” The original formula targeted mental taxation and overwork injuring the Heart-Spleen, producing palpitations, insomnia, and forgetfulness.

Key historical expansion: Ming dynasty physician Xue Ji added Dang Gui and Yuan Zhi to the original formula, significantly expanding its Blood-nourishing and Spirit-calming capacity. This expanded version became the standard clinical formulation used to the present day.

Later endorsements: Zhang Jingyue (Jing Yue Quan Shu, Ming dynasty) praised Gui Pi Tang as the essential formula for nourishing Blood and calming Spirit and strengthening Heart-Spleen. The Qing dynasty Yi Zong Jin Jian listed it as the first-choice formula for Heart-Spleen deficiency. It is now formally included in multiple versions of the Chinese Clinical Diagnosis and Treatment Guidelines for insomnia, anaemia, and related conditions.

II. Composition — Nine Herbs and Their Roles

Gui Pi Tang’s nine-herb composition is architecturally precise: four herbs address the Spleen-Qi and generative capacity; three herbs nourish Heart-Blood and calm the Spirit; one herb moves Qi to prevent stagnation; one herb harmonises. The standard clinical dosage: Bai Zhu 15g · Fu Shen 10g · Huang Qi 12g · Long Yan Rou 12g · Suan Zao Ren 12g · Ren Shen 6g · Mu Xiang 6g · Zhi Gan Cao 6g · Dang Gui 9g. Sheng Jiang 5 slices and Da Zao 1 piece are added as adjusting herbs.

Ren Shen (Ginseng) — jun (sovereign): greatly supplements original Qi; especially supplements Heart-Qi; strengthens cardiac function; improves shortness of breath and fatigue from Heart-Spleen Qi deficiency. The primary Qi-supplementing driver of the formula.

Huang Qi (Astragalus) — chen (minister): greatly supplements Spleen-Lung Qi; raises Yang and consolidates the body surface; the Spleen-Qi supplementing driver. Ren Shen + Huang Qi together provide the primary Qi-supplementing force of the formula.

Bai Zhu (Atractylodes) — chen (minister): strengthens Spleen and dries Damp; improves transformation and transportation function; ensures the Spleen effectively generates Blood from food and Qi. The Spleen-strengthening and digestive-supporting drug.

Dang Gui (Angelica sinensis) — chen (minister): nourishes Blood and activates Blood; supplements the Liver-Heart Blood that the Spleen generates; the Blood-nourishing driver. Addresses sallow complexion, head-dizziness, and Blood-deficiency symptoms directly. Added by Xue Ji to the original formula.

Long Yan Rou (Longan Arillus) — chen (minister): sweet-warm, nourishes Heart-Spleen Blood and calms the Spirit; simultaneously a food-medicine dual-use herb and a pharmacological agent. Directly supplements the Heart-Blood deficiency underlying insomnia, palpitations, and forgetfulness.

Suan Zao Ren (Jujube seed) — zuo (assistant): nourishes Liver-Blood and calms the Spirit; the primary sleep-promoting Spirit-calming drug. Sweet-sour, enters Heart and Liver channels; specifically addresses dream-disturbed insomnia and palpitations from Liver-Heart Blood deficiency. Used roasted (chao) to enhance sleep-promotion.

Fu Shen (Poria with pine root) — zuo (assistant): calms the Heart and settles the Spirit; enters the Heart channel; addresses Heart-Spirit agitation producing insomnia, palpitations, and startling. Gentler and specifically Heart-directed compared with Fu Ling. Its Spirit-calming action is gentle and sustained.

Yuan Zhi (Polygala) — zuo (assistant): dissolves Phlegm and opens orifices; communicates Heart and Kidney; calms Spirit and improves memory. Added by Xue Ji to the original formula; strengthens the memory-improving and Spirit-settling dimension, addressing the forgetfulness component of the Heart-Spleen pattern.

Mu Xiang (Costus root) — zuo (assistant): moves Qi and relieves pain; awakens the Spleen and promotes digestion. The pharmacological rationale: heavy supplementing formulas risk creating cloying stagnation in the Spleen-Stomach; Mu Xiang’s fragrant Qi-moving action prevents this, ensuring the Spleen-Stomach can receive and metabolise the supplements. The classical principle: “supplement without stagnation.”

Zhi Gan Cao (Honey-fried licorice) — shi (envoy): supplements Spleen and harmonises Stomach; coordinates all herbs; moderates the flavours and properties of the formula; the harmonising envoy.

III. Actions, Indications and the Heart-Spleen Pattern

Primary actions: Supplement Qi and nourish Blood; strengthen Spleen and nourish the Heart.

The Heart-Spleen deficiency pattern — understanding the mechanism:
The Spleen is responsible for transformation and transportation: it generates Blood from food. The Heart stores and governs Blood and houses the Spirit (shen). When mental taxation is excessive — chronic overthinking, anxiety, night-time studying, emotional stress, overwork — both Spleen and Heart are simultaneously depleted: the Spleen loses its transformation capacity (inadequate Blood generation) and the Heart loses its nourishment (inadequate Blood supply to house the Spirit). The two deficiencies are mutually reinforcing and produce the characteristic constellation of symptoms.

Core symptom constellation (Heart-Spleen deficiency):

• Heart symptoms: palpitations and fright-palpitations (xin ji zheng chong), insomnia and dream-disturbed sleep, difficulty falling asleep, easy awakening, forgetfulness and impaired memory, anxiety and restlessness
• Spleen symptoms: poor appetite and poor food intake, abdominal bloating, loose stool and loose-tendency bowel movement, fatigue and limb heaviness, mental depression and low energy
• Blood-deficiency manifestations: sallow dull-yellow complexion, pale lips, head-dizziness and eye-dizziness, tinnitus, pale nail beds
• Tongue and pulse: pale tongue with thin white coating; thread-and-weak (xi ruo) pulse

Typical modern presentations that match this pattern: office workers with chronic sleep disruption and daytime fatigue; students with examination anxiety and insomnia; women with post-partum Qi-Blood deficiency; patients with neurological exhaustion and functional heart palpitations; patients with chronic fatigue syndrome; menopausal women with insomnia and palpitations; patients after major illness or surgery with Qi-Blood dual deficiency.

IV. Formula Architecture — the Three Principles

Principle 1 — Simultaneous Heart-Spleen treatment:
The Heart governs Spirit (shen ming); the Spleen governs transformation and transportation. When Heart-Spleen deficiency occurs, the Heart loses nourishment and the Spirit is not settled (palpitations, insomnia); and the Spleen loses its transformation capacity and Blood-generation is insufficient (fatigue, poor appetite, pallor). Gui Pi Tang addresses both simultaneously: Bai Zhu + Huang Qi + Ren Shen + Zhi Gan Cao supplement Spleen-Qi and restore the Blood-generating source; Long Yan Rou + Dang Gui + Suan Zao Ren + Fu Shen nourish Heart-Blood and calm the Spirit. The clinical result: Spleen-Qi restored → Blood generation resumes → Heart-Blood replenished → Spirit settles.

Principle 2 — Qi-Blood dual supplementation:
Ren Shen + Huang Qi + Bai Zhu + Zhi Gan Cao supplement Qi and strengthen Spleen (the Blood-generation source); Long Yan Rou + Dang Gui nourish Blood directly. Qi and Blood are mutually dependent: Qi generates Blood (qi neng sheng xue); Blood carries Qi (xue wei qi mu). Qi-Blood dual supplementation resolves both the Qi-deficiency fatigue and the Blood-deficiency insomnia-palpitations simultaneously. The formula embodies the classical principle: “Qi is the commander of Blood; Blood is the mother of Qi.”

Principle 3 — Supplement with Qi-movement to prevent stagnation:
Mu Xiang is the pharmacological keystone of the formula’s architecture. Heavy supplementing herbs (Ren Shen, Huang Qi, Long Yan Rou, Dang Gui) risk creating cloying stagnation in the Spleen-Stomach, worsening the very digestive function they aim to support. Mu Xiang’s fragrant Qi-moving action keeps the Spleen-Stomach receptive, ensures the supplements are transformed and distributed rather than stagnating, and allows the formula to be used long-term without generating digestive side effects. The guiding principle: bu er bu zhi (“supplement without stagnation”).

V. Clinical Modifications

Gui Pi Tang is clinically flexible and adapts readily to sub-patterns within the Heart-Spleen deficiency framework:

• Severe palpitations and insomnia: add Yuan Zhi (if not already included), Bai Zi Ren, and Ye Jiao Teng to amplify the Spirit-calming and sleep-promoting force
• Prominent Blood deficiency with sallow complexion: add Shu Di Huang, He Shou Wu, and E Jiao Zhu to strengthen the Blood-nourishing action
• Spleen-deficiency Damp exuberance with poor appetite and loose stool: add Shan Yao, Lian Zi Rou, and Yi Yi Ren to strengthen the Spleen and drain Damp
• Qi-deficiency spontaneous sweating with prominent fatigue: add Fu Xiao Mai, Duan Long Gu, and Duan Mu Li to consolidate the surface and stop sweating
• Severe Qi-Blood dual deficiency: combine with Si Wu Tang for stronger Blood-nourishing
• Heart-Yin deficiency more prominent: combine with or alternate with Tian Wang Bu Xin Dan for stronger Yin-nourishing

All modifications should be guided by a TCM physician following pattern differentiation.

VI. Comparison with Similar Formulas

Clinical selection rule: Insomnia with Yin deficiency-Fire signs (heat, night sweats, dry throat) → Tian Wang Bu Xin Dan. Insomnia with Spleen deficiency, poor appetite, fatigue, and pallor → Gui Pi Tang. Irregular pulse from Qi-Yin deficiency → Zhi Gan Cao Tang. Pure Spleen-Qi deficiency without Heart symptoms → Si Jun Zi Tang.

VII. Clinical Applications

Cardiovascular: palpitations and fright-palpitations from Heart-Spleen deficiency; adjunctive in coronary artery disease and arrhythmia of Heart-Spleen deficiency pattern; modern research confirms Gui Pi Tang regulates cardiac function, improves myocardial blood supply, and enhances myocardial contractile force.

Neurology and sleep: insomnia, forgetfulness, and neurological exhaustion; post-exam and chronic stress insomnia; menopausal insomnia and palpitations; neurological exhaustion; modern research confirms Gui Pi Tang regulates neurotransmitter secretion (including serotonin), improves sleep architecture, reduces anxiety and depressive symptoms, and enhances memory. Many patients report: “palpitations lessened, sleep improved, and mental clarity significantly recovered.”

Haematology: Qi-Blood deficiency anaemia; Blood-deficiency from Spleen-deficiency (the Spleen fails to generate Blood); modern research confirms Gui Pi Tang promotes erythropoiesis, increases haemoglobin and red blood cell count, improves sallow complexion and haematological parameters. Also used in haematological conditions: aplastic anaemia, immune thrombocytopenic purpura, and functional uterine haemorrhage — all of Heart-Spleen deficiency pattern.

Gastroenterology: Spleen-Stomach deficiency poor appetite, abdominal bloating, loose stool; adjunctive in chronic gastritis and peptic ulcer of Heart-Spleen deficiency pattern.

Gynaecology: menstrual irregularity from Qi-Blood deficiency with mental fatigue; functional uterine haemorrhage (Spleen failing to govern Blood); post-partum Qi-Blood dual deficiency.

Post-illness recovery: post-serious illness, post-surgical, and post-chemotherapy Qi-Blood dual deficiency.

VIII. Dosage and Administration

Standard decoction: one dose daily, water-decocted, taken in two divided doses. Standard clinical dosage: Bai Zhu 15g · Fu Shen 10g · Huang Qi 12g · Long Yan Rou 12g · Suan Zao Ren (roasted) 12g · Ren Shen 6g · Mu Xiang 6g · Zhi Gan Cao 6g · Dang Gui 9g · Yuan Zhi 6g · Sheng Jiang 5 slices · Da Zao 1 piece.

Modern formulations: Gui Pi Tang (Hoi Tin) and Gui Pi Tang (Nong Ben Fang) are available as granules, pills, and capsules for convenient daily use — follow product-specific instructions and TCM physician guidance on duration and dose.

IX. Contraindications and Safety

Contraindications — patterns where Gui Pi Tang is inappropriate:

• Yin deficiency-Fire uprising (yin xu huo wang): tidal flushing, palm-and-sole Heat, night sweats, heart-vexation, dry mouth and dry throat — Gui Pi Tang’s warm-supplementing nature will aggravate deficiency-Heat; use Tian Wang Bu Xin Dan or Zhi Bai Di Huang Wan instead
• Damp-Heat exuberance or Phlegm-Heat disturbing the Spirit: insomnia with thick-greasy coating, heavy sensation, bitter mouth, or obvious Heat signs; Gui Pi Tang’s warm-supplementing herbs will worsen Damp-Heat stagnation
• Active exterior-pathogen illness (cold, fever, infection): all supplementing formulas are contraindicated during active exterior-pathogen invasion; wait until pathogen is resolved before using Gui Pi Tang
• Liver-Qi stagnation-type insomnia: insomnia driven by emotional suppression, Liver-Qi binding, irritability and rib-side distension — Gui Pi Tang does not address Liver-Qi stagnation; use Chai Hu Shu Gan San or Xiao Yao San framework instead

Special populations: pregnancy — use with TCM physician guidance; do not self-administer. Children — adjust dose according to age and constitution under physician supervision.

Dietary guidance during treatment: avoid raw-cold, oily, and spicy-irritating foods; avoid radish and strong tea (may reduce supplementing efficacy); maintain regular sleep schedule.

The most important clinical rule: Gui Pi Tang is pattern-specific. It must only be used for confirmed Heart-Spleen deficiency pattern with pale tongue, thread-weak pulse, and the core symptom constellation (palpitations, insomnia, forgetfulness, fatigue, sallow complexion, poor appetite). Using it for patterns it does not address — especially Yin deficiency-Fire or Damp-Heat — will worsen the condition. Always seek TCM physician pattern differentiation before use.

X. Modern Research

Neurological: Gui Pi Tang regulates neurotransmitter secretion (increases serotonin and other neurotransmitters); improves CNS function; relieves anxiety and depressive symptoms; improves sleep quality and architecture; enhances memory consolidation.

Cardiovascular: improves myocardial blood supply; enhances myocardial contractile force; reduces myocardial oxygen consumption; regulates blood lipids and blood pressure; cardiovascular-protective effect.

Immunological: Gui Pi Tang enhances macrophage phagocytic activity; promotes lymphocyte proliferation and differentiation; regulates immune balance; improves resistance to external pathogens.

Haematological: promotes erythropoiesis; increases haemoglobin and red blood cell count; adjunctive in aplastic anaemia, immune thrombocytopenic purpura, and functional uterine haemorrhage of Qi-Blood deficiency pattern.

Gui Pi Tang has been in continuous clinical use for nearly eight centuries. Its trajectory from the Song dynasty Ji Sheng Fang through Ming dynasty expansion to modern clinical guidelines reflects a formula whose pharmacological validity has been continuously reconfirmed across generations. Modern research increasingly provides molecular-level explanations for actions that classical physicians documented empirically: neurotransmitter regulation for Spirit-calming, erythropoiesis for Blood-supplementing, immune modulation for Qi-consolidating. It remains the most important formula for Heart-Spleen deficiency in modern East Asian clinical practice.
