Overview

Tai Shan Pan Shi San — the “Powder Stable as Mount Tai” — is from the Ming-dynasty physician Wan Quan’s Wan Shi Mi Chuan. It is one of the most important classical formulas for threatened miscarriage^[15] from Qi and Blood deficiency. The name evokes the stability and immovable strength of Mount Tai, one of China’s sacred mountains — the formula is intended to anchor the pregnancy as solidly as the mountain.

The composition builds on Ba Zhen Tang (Qi and Blood tonification) with the addition of Xu Duan (Kidney Yang and ligament-strengthening), Sha Ren (Spleen-strengthening and pregnancy-calming), Huang Qin (small dose to clear any Heat that might disturb the fetus) and Nuo Mi (glutinous rice) for further pregnancy-supportive nourishment.

I prescribe Tai Shan Pan Shi San as part of bespoke herbal formulas from pharmaceutical-grade granules sourced from Sun Ten in Taiwan, under careful obstetric supervision.

TCM pattern

Tai Shan Pan Shi San is prescribed for threatened miscarriage from Qi and Blood deficiency:

• Threatened miscarriage — light spotting or bleeding in early pregnancy
• Lower back ache
• Mild lower abdominal pain or pressure
• Fatigue, weakness
• Pale complexion
• Mild palpitations
• History of recurrent miscarriage
• Tongue — pale, possibly with teethmarks
• Pulse — thin, weak, possibly slippery (pregnancy pulse)

Key herbs

2. Huang Qi (Rx. Astragali, 12-15g) — tonifies Spleen and Lung Qi; holds blood
3. Bai Zhu (Rz. Atractylodis Macrocephalae, 1.5-10g) — tonifies Spleen and stabilises pregnancy

Formula actions

1. Tonifies Qi and Blood
2. Strengthens Kidney
3. Calms and stabilises the fetus
4. Stops bleeding
5. Prevents miscarriage

Conditions treated

1. Threatened miscarriage in the first trimester with Qi-Blood deficiency pattern — see miscarriage
2. Recurrent miscarriage — prophylactic use from confirmation of pregnancy
3. Subchorionic haematoma in early pregnancy
4. Light bleeding in early pregnancy with deficiency picture
5. Preparation for pregnancy after recurrent miscarriage — building Qi and Blood before conception
6. Early pregnancy support in IVF after embryo transfer

Comparisons with related formulas

• Shou Tai Wan — for threatened miscarriage from Kidney deficiency; different pattern.
• Ba Zhen Tang — the base Qi-Blood formula without pregnancy-specific additions.
• Modified Ai Ye + Blood-tonic combinations — for threatened miscarriage with bleeding from Blood deficiency, using plant Blood-nourishing alternatives.

Cautions

Threatened miscarriage requires obstetric assessment — ultrasound, beta-hCG levels and clinical examination are essential. Chinese herbs are an adjunct to obstetric care.

Severe pain, heavy bleeding, dizziness^[22] or fever in early pregnancy is a medical emergency — call 999 or attend A&E to exclude ectopic pregnancy and complete miscarriage.

Always consult a qualified Chinese herbalist with experience in pregnancy. Self-prescribing in pregnancy is dangerous.

Always consult a qualified Chinese herbalist registered with the RCHM.

How does Tai Shan Pan Shi San work?

Tai Shan Pan Shi San (“Mount Tai Stability Powder”) combines Qi-tonifying herbs (Ren Shen, Huang Qi, Bai Zhu, Sha Ren, Gan Cao), Blood-tonifying herbs (Dang Gui, Bai Shao, Shu Di Huang, Chuan Xiong), and Kidney-stabilising herbs (Xu Duan, Huang Qin, Sha Ren) to address the most common TCM pattern in early-pregnancy threatened miscarriage — Spleen-Kidney Qi deficiency with Blood deficiency. The formula is widely used in TCM clinical practice as part of pregnancy support and may help support implantation and early pregnancy in patients with recurrent miscarriage, particularly where the pattern reflects underlying deficient constitution rather than structural or chromosomal causes. Treatment runs alongside (not instead of) conventional obstetric care.

Dosage and forms

• Pharmaceutical-grade granules — 4–6 g/day in 2–3 divided doses. The most individualised form. Typical course: started at confirmed positive pregnancy test and continued through the first trimester (10–12 weeks gestation).
• Patent pills — less widely available in patent form; granule is the standard modern delivery method.

I prescribe pharmaceutical-grade granules from Sun Ten in Taiwan, individualised within a bespoke prescription. The formula is one of the most carefully prescribed in TCM and requires a qualified herbalist with pregnancy experience.

Cautions and contraindications

• Heat patterns or marked Yin deficiency — the formula is mildly warming; in marked Yin-deficient patients the dose is reduced or the formula is modified
• Confirmed ectopic pregnancy — contraindicated; ectopic pregnancy requires urgent gynaecological management
• Confirmed miscarriage (already lost) — the formula does not reverse pregnancy loss once it has occurred; different formulas support post-miscarriage recovery
• Self-prescription — pregnancy herbal prescribing requires specialist expertise; do not self-prescribe

Always work with a qualified Chinese herbalist registered with the Register of Chinese Herbal Medicine (RCHM) who has specific experience in pregnancy prescribing. Treatment is complementary to NHS antenatal care, not a replacement for it.

Online Chinese herbal consultations

I prescribe Chinese herbal medicine through online video consultations for patients throughout the UK and internationally. After a full case-history consultation reviewing your TCM pattern, presenting complaint, current medications and individual constitution, a bespoke prescription is formulated and the pharmaceutical-grade granules from Sun Ten in Taiwan are posted directly to your door. I am a member of the British Acupuncture Council (BAcC) and the Register of Chinese Herbal Medicine (RCHM) with over 25 years of clinical experience.

Treatment runs alongside (not instead of) conventional medical care. Always continue to be seen by your GP or specialist for any diagnosed condition; herbal medicine is used as a complementary therapy. See the prices page for consultation and dispensing fees.

Comparison with related formulas

• Shou Tai Wan — the simpler four-herb “Fetus Longevity Pill” (Tu Si Zi, Sang Ji Sheng, Du Zhong, E Jiao — note: I substitute E Jiao with plant alternatives). Use as a gentler maintenance formula or in combination with Tai Shan Pan Shi San.
• Ba Zhen Tang — Qi-and-Blood double-tonifying formula. Useful pre-conception for couples in the trying-to-conceive phase with Qi-Blood deficiency.
• Modified Si Jun Zi Tang — gentler Spleen Qi tonification. Sometimes used in milder presentations.

Frequently asked questions

Does Tai Shan Pan Shi San actually prevent miscarriage?

The formula targets the TCM Spleen-Kidney Qi deficiency pattern with Blood deficiency that underlies many recurrent miscarriages with no identifiable conventional cause. It does not reverse chromosomal abnormalities or structural causes of pregnancy loss; for those, conventional gynaecological investigation and management apply. In TCM clinical practice it may help support early pregnancy in patients whose pattern fits and is typically used alongside conventional recurrent miscarriage workup and management. Effect varies by individual.

Is Tai Shan Pan Shi San safe during pregnancy?

Yes — this is one of the few Chinese herbal formulas specifically designed for early pregnancy and traditionally used to support the pregnancy. The composition uses Sha Ren and Huang Qin to ensure the Qi-tonifying herbs don't aggravate any underlying Heat. Treatment requires specialist supervision; do not self-prescribe.

How long do I take Tai Shan Pan Shi San?

Typically from confirmed positive pregnancy test (around 4–5 weeks gestation by LMP, or transfer day +14 for IVF cycles) through to the end of the first trimester (12–13 weeks). For patients with significant recurrent miscarriage history, treatment may continue into early second trimester at reduced dose. After the first trimester the formula is typically tapered as the placental hormonal support stabilises.

Can I take it alongside progesterone supplementation?

Yes — vaginal or oral progesterone supplementation is widely used alongside the formula in patients with luteal-phase support requirements or known low-progesterone history. No clinically significant interactions have been reported. The combination addresses both the conventional hormonal support and the underlying TCM constitutional pattern.

What about Tai Shan Pan Shi San after IVF or ICSI?

Many IVF patients use the formula from transfer day or from positive beta-hCG, alongside continued progesterone support. The combination of post-transfer acupuncture, daily herbal granule formula and continued progesterone provides comprehensive early-pregnancy support. Treatment runs alongside the IVF clinic's standard luteal-phase support protocols.
