Ban Xia Bai Zhu Tian Ma Tang: TCM Formula for Dizziness and Vertigo
Learn about Ban Xia Bai Zhu Tian Ma Tang (半夏白术天麻汤) — the classic TCM formula that treats dizziness, vertigo, and headache caused by phlegm-dampness and Liver wind, with practical usage guidance.
What is Ban Xia Bai Zhu Tian Ma Tang?
Ban Xia Bai Zhu Tian Ma Tang (半夏白术天麻汤) — “Pinellia, Atractylodes, and Gastrodia Decoction” — is one of the most important formulas in TCM for treating dizziness and vertigo caused by phlegm-dampness. Created by the eminent Ming Dynasty physician Li Dong Yuan, this formula addresses a pattern TCM calls “wind phlegm” (风痰) — where internal phlegm combines with internal wind to produce the sensation of spinning, unsteadiness, and headache.
The formula’s name comes from its three hero ingredients: Ban Xia (Pinellia) to dry phlegm, Bai Zhu (White Atractylodes) to strengthen the Spleen and prevent phlegm formation, and Tian Ma (Gastrodia) to extinguish wind and stop dizziness.
The Pattern It Treats: Wind Phlegm
In TCM theory, this formula targets a specific pattern cascade:
Spleen deficiency (weak digestion)
→ Cannot properly transform fluids
→ Fluids accumulate and form phlegm-dampness
→ Phlegm blocks the clear Yang from rising to the head
→ Internal wind stirs (often from Liver involvement)
→ Dizziness, vertigo, heavy-headedness, headacheThe key principle: “No phlegm, no dizziness” (无痰不作眩). TCM considers phlegm-dampness obstruction to be one of the primary causes of chronic dizziness and vertigo.
Key Symptoms
- Dizziness or vertigo — a spinning sensation, feeling unsteady
- Headache — often heavy, dull, or pressing
- Nausea or vomiting — phlegm affecting the Stomach
- Heavy sensation in the head — “head wrapped in a cloth”
- Chest oppression — phlegm blocking the chest
- Poor appetite — Spleen weakness
- Greasy tongue coating — white and greasy, indicating phlegm-dampness
- Slippery or wiry pulse — phlegm with wind
The Ingredients
| Herb | Chinese | Role in Formula |
|---|---|---|
| Ban Xia (Pinellia) | 半夏 | Dries dampness, transforms phlegm, stops vomiting |
| Bai Zhu (White Atractylodes) | 白术 | Tonifies Spleen, dries dampness — treats the root |
| Tian Ma (Gastrodia) | 天麻 | Extinguishes wind, stops dizziness — key symptom herb |
| Fu Ling (Poria) | 茯苓 | Drains dampness, strengthens Spleen |
| Chen Pi (Tangerine Peel) | 陈皮 | Regulates Qi, dries dampness, helps transform phlegm |
| Gan Cao (Licorice) | 甘草 | Harmonizes the formula, tonifies Spleen |
| Sheng Jiang (Fresh Ginger) | 生姜 | Warms the middle, reduces Ban Xia toxicity |
| Da Zao (Jujube) | 大枣 | Tonifies Spleen, harmonizes |
Formula Structure
The formula is built in three layers:
- Treat the branch (symptoms): Tian Ma extinguishes wind and stops dizziness directly
- Transform the phlegm: Ban Xia, Chen Pi dry and move phlegm
- Treat the root: Bai Zhu, Fu Ling strengthen the Spleen so it stops producing phlegm
This three-layer approach is what makes the formula effective both acutely and preventively.
How It Works
Extinguishes Wind and Stops Dizziness
Tian Ma (Gastrodia) is the key herb here. In TCM, Tian Ma is considered the most important herb for dizziness regardless of the cause. It enters the Liver channel and calms internal wind — the TCM mechanism behind the spinning, dizzy sensation.
Transforms Phlegm and Dries Dampness
Ban Xia is the chief phlegm-transforming herb. Combined with Chen Pi and Fu Ling (this trio forms the core of Er Chen Tang, the classic phlegm formula), it effectively breaks up existing phlegm and prevents new formation.
Strengthens the Spleen
Bai Zhu tonifies Spleen Qi and dries dampness. Since the Spleen is the organ responsible for transforming fluids in TCM, strengthening it addresses the root cause of chronic phlegm production.
Clinical Applications
Vertigo (Benign Paroxysmal Positional Vertigo)
The most direct modern application — spinning dizziness, especially with position changes, accompanied by nausea. When the tongue shows a greasy coating, this formula is strongly indicated.
Meniere’s Disease
Characterized by vertigo, tinnitus, and hearing loss. In TCM, this is often diagnosed as wind-phlegm obstructing the head, and Ban Xia Bai Zhu Tian Ma Tang is a standard prescription.
Hypertension with Dizziness
When high blood pressure presents with heavy-headedness, dizziness, chest oppression, and phlegm signs, this formula can help manage symptoms. It is often modified with herbs that calm Liver Yang.
Chronic Dizziness from Poor Digestion
Patients who experience dizziness after eating heavy meals, with bloating, nausea, and fatigue — this reflects the Spleen deficiency root that the formula addresses.
Headache with Phlegm-Dampness
Heavy, pressing headaches with a feeling of “wetness” or heaviness, worse in damp weather or after eating greasy food.
Common Modifications
Experienced practitioners modify the base formula based on specific presentations:
| Modification | Add | For |
|---|---|---|
| Liver Yang rising | Gou Teng, Shi Jue Ming | Hypertension, red face, irritability |
| Severe phlegm | Dan Nan Xing, Bai Jie Zi | Copious phlegm, thick coating |
| Dampness dominant | Cang Zhu, Hou Po | Heavy limbs, very greasy coating |
| Qi deficiency | Dang Shen, Huang Qi | Marked fatigue, very pale tongue |
| Nausea dominant | Zhu Ru, Dai Zhe Shi | Severe vomiting with dizziness |
How to Take
Forms
- Decoction: The most effective form; simmer for 25–30 minutes
- Granules: 6–9g dissolved in warm water, twice daily
- Patent pills: Available as a classic formula patent; follow label directions
Timing
- Take between meals for best absorption
- For vertigo: Take at first sign of symptoms and 2–3 times daily during episodes
- For prevention: Take twice daily for 2–4 weeks
Duration
- Acute episodes: 1–2 weeks
- Chronic conditions: 4–8 weeks, then reassess
- Prevention: May be taken cyclically during problem seasons (damp weather)
Precautions
- Yin deficiency dizziness: If dizziness is accompanied by dry mouth, night sweats, red tongue with little coating, this formula may be too drying. Consider Tian Ma Gou Teng Yin instead
- Liver Yang rising (without phlegm): Pure Liver Yang patterns (red face, bitter taste, wiry pulse without greasy coating) need different formulas
- Pregnancy: Ban Xia requires caution during pregnancy; consult a practitioner
- Dehydration: The drying herbs may worsen dry conditions
