Xiang Sha Liu Jun Zi Tang (香砂六君子汤): The Spleen-Stomach Formula for Qi Stagnation with Deficiency
Xiang Sha Liu Jun Zi Tang expands the classic Six Gentlemen Decoction with Mu Xiang and Sha Ren to tonify Spleen Qi while moving stagnant Qi and drying dampness. Learn when this formula beats the simpler Si Jun Zi Tang or Liu Jun Zi Tang.
When “Just Tonify” Is Not Enough
A common frustration in clinical practice: a patient with clear Spleen Qi deficiency — fatigue, poor appetite, loose stools — is given a tonifying formula like Si Jun Zi Tang (Four Gentlemen Decoction), and instead of improving, they feel more bloated and full. The deficiency is real, but so is the stagnation. Tonifying herbs are heavy and cloying; if the digestive engine is too sluggish to process them, they sit there and create exactly the fullness they were meant to fix.
Xiang Sha Liu Jun Zi Tang (香砂六君子汤) was built for this catch-22. It tonifies Spleen Qi while simultaneously moving the stagnant Qi and transforming the dampness that block digestion. The name translates to “Aucklandia and Amomum Six Gentlemen Decoction” — the Six Gentlemen base plus two aromatic Qi-movers.
The Formula’s Lineage
Understanding this formula means seeing its place in a family of increasingly sophisticated Spleen tonics:
| Formula | Adds | Best For |
|---|---|---|
| Si Jun Zi Tang (Four Gentlemen) | — | Pure Spleen Qi deficiency |
| Liu Jun Zi Tang (Six Gentlemen) | + Chen Pi, Ban Xia | Qi deficiency with dampness/phlegm |
| Xiang Sha Liu Jun Zi Tang | + Mu Xiang, Sha Ren | Qi deficiency with dampness AND Qi stagnation (fullness, bloating) |
Each step adds herbs that address an additional layer of complication. Xiang Sha Liu Jun Zi Tang is the most “complete” of the three — it tonifies, dries, moves, and warms.
Composition and Logic
| Herb | Pinyin | Role | Function |
|---|---|---|---|
| Ren Shen (Ginseng) | 人参 | Chief (with Bai Zhu) | Strongly tonifies primal Qi, strengthens Spleen |
| Bai Zhu (White Atractylodes) | 白术 | Chief | Tonifies Spleen, dries dampness |
| Fu Ling (Poria) | 茯苓 | Deputy | Drains dampness via urination, supports Spleen |
| Zhi Gan Cao (Honey-fried Licorice) | 炙甘草 | Assistant | Harmonizes, tonifies Spleen, moderates the formula |
| Chen Pi (Tangerine Peel) | 陈皮 | Assistant | Moves Qi, dries dampness, reduces phlegm |
| Ban Xia (Pinellia) | 半夏 | Assistant | Dries dampness, transforms phlegm, descends rebellious Qi |
| Mu Xiang (Aucklandia) | 木香 | Assistant | Strongly moves Qi, stops pain, eases fullness |
| Sha Ren (Cardamom) | 砂仁 | Assistant | Transforms dampness, moves Qi, warms the middle |
The Two Herbs That Define the Formula
Mu Xiang and Sha Ren are what make this formula distinct from Liu Jun Zi Tang:
- Mu Xiang (木香) is the strongest Qi-moving herb for the digestive tract. It relieves bloating, distension, and the crampy pain that comes with stagnant Spleen/Stomach Qi. It is the herb of choice when the patient says “I feel stuffed and uncomfortable after just a few bites.”
- Sha Ren (砂仁) transforms dampness and warms the middle while also moving Qi. It is aromatic and drying — ideal when the tongue coating is greasy and the appetite is poor. Traditionally added late in decoction to preserve its volatile oils.
Together they solve the central problem: making the tonifying base tolerable and effective for a digestive system that is both weak and jammed.
Key Indications
The formula is indicated for Spleen-Stomach Qi deficiency with Qi stagnation and dampness.
Classic symptoms:
- Poor appetite, eating very little
- Bloating, fullness, and distension — especially after eating (the hallmark)
- Belching, nausea, occasional vomiting
- Loose stools or undigested food in stool
- Fatigue, weak limbs, soft voice
- A pale tongue with a white, greasy coating
- A thin or moderate pulse that may be slightly wiry in the middle position
Modern applications:
- Chronic gastritis and atrophic gastritis with this pattern
- Functional dyspepsia — “I feel full right away, bloated after meals”
- Irritable bowel syndrome (IBS) — diarrhea-predominant with bloating
- Post-illness or post-surgical digestive weakness
- Loss of appetite during recovery or in the elderly
How to Choose Among the “Gentlemen” Formulas
A quick decision guide:
- Tired, no appetite, pale — but no bloating or greasy tongue → Si Jun Zi Tang (pure tonification)
- Above + nausea, phlegm, greasy tongue coating, but tolerable fullness → Liu Jun Zi Tang (add dampness-drying)
- Above + significant bloating, distension, belching, “stuffed after a few bites” → Xiang Sha Liu Jun Zi Tang (add Qi-moving)
The deciding question is simple: how much fullness and stagnation is there? The more the patient complains of bloating and distension, the further down this list you go.
A Note on Modern Digestive Health
Xiang Sha Liu Jun Zi Tang lines up neatly with a modern clinical reality: many people’s digestive complaints are a mix of genuine weakness (poor diet, overwork, stress exhausting the system) and functional stagnation (stress-driven motility problems, bloating). This is one reason the formula remains one of the most commonly prescribed digestive formulas in contemporary TCM and Japanese Kampo practice (where it is known as Kōshakurikkunshitō).
Dosage and Use
| Form | Typical Use | Notes |
|---|---|---|
| Decoction | Daily, divided doses | Sha Ren added in the last 5 minutes of cooking |
| Granules | Convenient form | Popular for chronic digestive support |
| Patent pills | Sustained use | Common for IBS/dyspepsia maintenance |
Courses typically run 2 to 4 weeks for a clear effect, often longer for chronic conditions. As the bloating eases and appetite returns, some practitioners transition to a simpler formula (e.g., Liu Jun Zi Tang or Si Jun Zi Tang) for maintenance.
Precautions
- Yin deficiency with dryness (dry mouth, constipation, little coating, red tongue) — the warming, drying herbs can worsen it
- Stomach fire / heat patterns (burning epigastric pain, sour regurgitation, yellow coating) — not appropriate; the warming herbs aggravate heat
- Pregnancy — Ban Xia is traditionally contraindicated in pregnancy; Mu Xiang and Sha Ren are pungent and moving. Use only under professional supervision.
Key Takeaways
- Xiang Sha Liu Jun Zi Tang is the “complete” Spleen tonic — it tonifies Qi, dries dampness, transforms phlegm, and moves stagnant Qi
- It shines when deficiency is complicated by bloating and fullness — the case where pure tonification backfires
- Mu Xiang and Sha Ren are the two herbs that distinguish it from Liu Jun Zi Tang
- Ideal for chronic gastritis, functional dyspepsia, and IBS presenting with the mixed deficiency-stagnation pattern
- Avoid in Yin-deficient or heat-pattern digestive conditions

FAQ
What is the difference between Liu Jun Zi Tang and Xiang Sha Liu Jun Zi Tang?
Liu Jun Zi Tang (Six Gentlemen Decoction) tonifies Spleen Qi and dries dampness/phlegm. Xiang Sha Liu Jun Zi Tang adds Mu Xiang and Sha Ren, two Qi-moving and damp-transforming herbs, making it better when there is marked Qi stagnation — bloating, fullness, belching, or nausea alongside the deficiency. If pure deficiency with mild dampness is the picture, Liu Jun Zi Tang suffices; add the 'Xiang Sha' version when stagnation and fullness dominate.
What symptoms is Xiang Sha Liu Jun Zi Tang used for?
It is used for Spleen-Stomach Qi deficiency complicated by Qi stagnation and dampness: poor appetite, bloating and fullness after eating, belching, nausea, loose stools, fatigue, and a pale tongue with a white greasy coating. Modern applications include chronic gastritis, functional dyspepsia, and irritable bowel syndrome with this pattern.
