Ban Xia Bai Zhu Tian Ma Tang — Pinellia, Atractylodes & Gastrodia Decoction

半夏白术天麻汤 | Bàn Xià Bái Zhú Tiān Má Tāng

Overview

Ban Xia Bai Zhu Tian Ma Tang is a classical Chinese herbal formula first recorded in Yi Xue Xin Wu (Medical Revelations) by Cheng Guo-Peng in 1732, with an earlier version by Li Dong-Yuan in 1249. It is one of the most important formulas in traditional Chinese medicine for treating dizziness, vertigo and headache caused by Wind-Phlegm rising to disturb the head, and has a particularly strong evidence base for vertebrobasilar insufficiency vertigo, Ménière's disease and Phlegm-Damp pattern migraines.

The formula works by simultaneously drying Dampness, transforming Phlegm, calming Liver Wind and strengthening the Spleen — addressing both the accumulated pathology (Wind-Phlegm obstructing the clear orifices) and the underlying deficiency (Spleen Qi deficiency) that generates the Phlegm in the first place.

I prescribe pharmaceutical-grade granules from Sun Ten in Taiwan, tested to the highest international quality and safety standards. Each prescription is tailored to the individual's pattern and adjusted at follow-up.

Composition

The classical formula consists of eight herbs:

• Ban Xia (Pinellia rhizome, ginger-prepared) — the chief herb; dries Dampness, transforms Phlegm and directs rebellious Qi downward
• Tian Ma (Gastrodia rhizome) — calms the Liver, extinguishes Wind and stops dizziness
• Bai Zhu (Atractylodes macrocephala rhizome) — the highest-dosed herb; tonifies Spleen Qi and dries Dampness
• Fu Ling (Poria) — supports the Spleen and drains Dampness through the urine
• Ju Hong / Chen Pi (red tangerine peel) — regulates Qi and further breaks down Phlegm
• Gan Cao (licorice root) — tonifies Spleen Qi and harmonises the formula
• Sheng Jiang (fresh ginger) — warms the Middle, assists Ban Xia in transforming Phlegm
• Da Zao (jujube fruit) — tonifies Qi and harmonises the Stomach and Spleen

Actions

• Dries Dampness and transforms Phlegm
• Extinguishes internal Wind
• Strengthens the Spleen
• Directs rebellious Qi downward
• Stops dizziness and headache

TCM Pattern Treated

Ban Xia Bai Zhu Tian Ma Tang is designed for Wind-Phlegm rising to disturb the head, arising from Spleen Qi deficiency with Phlegm-Damp accumulation. The pathomechanism begins with the Spleen failing to transport and transform fluids; Dampness accumulates and congeals into Phlegm; the Phlegm then stirs up Liver Wind, and the combined Wind-Phlegm rises to obstruct the clear orifices of the head, preventing clear Yang from ascending.

Clinical Indications

The characteristic presentation includes:

• Dizziness and vertigo — often rotational, with a sensation of the room spinning
• Headache — heavy, muzzy, oppressive, as if the head were wrapped
• Nausea and vomiting — particularly with Phlegm-Damp
• Heavy-headed sensation, brain fog, difficulty concentrating
• Chest oppression or fullness, a feeling of stifling in the chest
• Copious sputum, a sticky or clammy mouth
• Poor appetite, loose stools
• Tongue: swollen, pale, with a thick greasy white coating
• Pulse: wiry and slippery

Conditions Commonly Treated

In modern clinical practice Ban Xia Bai Zhu Tian Ma Tang is used for a range of conditions that present with the Wind-Phlegm pattern:

• Vertigo and Ménière's disease — the single most researched indication
• Vertebrobasilar insufficiency vertigo
• Benign paroxysmal positional vertigo (BPPV) with Phlegm-Damp
• Phlegm-Damp pattern migraines — particularly those with nausea and heavy-headed sensation
• Tension headaches with oppressive quality
• Hypertension with dizziness and Phlegm-Damp signs
• Motion sickness
• Sinusitis with heavy-headed sensation

Research Evidence

A systematic review and meta-analysis of randomised controlled trials evaluating Ban Xia Bai Zhu Tian Ma Decoction for vertebrobasilar insufficiency vertigo found significant improvement in symptom scores compared to conventional medication alone, with fewer adverse events. Additional research has demonstrated vasodilatory effects through the nitric oxide pathway, improved cerebral microcirculation, and a reduction in neuronal apoptosis in ischaemic models. A population-based cohort study also found a decreased risk of stroke in patients receiving TCM for vertigo, with Ban Xia Bai Zhu Tian Ma Tang among the most commonly prescribed formulas.

Prescribing Notes

Where Liver Yang rising is prominent alongside Phlegm — for example in migraines with significant irritability, red face and headaches at the temples — I often combine or alternate Ban Xia Bai Zhu Tian Ma Tang with Tian Ma Gou Teng Yin. Where Phlegm-Heat predominates — heavier mental symptoms, bitter taste, thicker yellow coating — I consider modifying towards Wen Dan Tang instead.

For chronic dizziness with significant fatigue, I often add herbs to further tonify Qi; for pronounced Blood stasis signs (fixed stabbing pain, purple tongue), blood-moving herbs are added.

Cautions

Ban Xia Bai Zhu Tian Ma Tang is warming and drying. It is not appropriate for Yin-deficient dizziness (characterised by a red peeled tongue, five-palm heat, night sweats and a thin rapid pulse), nor for dizziness from Blood deficiency alone. Like all Chinese herbal formulas it should only be taken under the supervision of a qualified practitioner.

Online Consultation
