What Gui Pi Tang is for
Gui Pi Tang is for skin that is pale, thin and slow to repair, with bruises that appear at the slightest knock and small purpuric dots where the Spleen is failing to hold the Blood in its vessels. The surface is underfed rather than inflamed. Nothing in the picture is hot or red, and the formula is a rebuild: it lifts the production of Qi and Blood so the skin is supplied again.
The skin is pale rather than white, thin and papery in texture, and a dull or sallow tone sits over the whole face. Knocks leave bruises that last, and small purpuric dots may appear on the limbs without any injury at all. Cracks and small wounds heal slowly and stay pale at the edges rather than closing cleanly. The tissue feels underfilled, which is the visible sign of Blood that is not being produced in enough quantity to reach the surface of the skin.
The mechanism is production rather than repair. Huang Qi, Ren Shen, Bai Zhu and Gan Cao rebuild the Qi that drives the making of Blood. Long Yan Rou, Dang Gui and Suan Zao Ren supply the Blood itself, and Dang Gui is the herb that returns colour to the surface. Fu Shen and Yuan Zhi settle the spirit, and Mu Xiang keeps the rich herbs moving so the rebuilding does not congest. The skin improves as the supply improves, which is why the change is measured in weeks rather than days.
It belongs to the depleted stage of a skin complaint, after any hot, red or weeping phase has passed. Pale skin that bruises, purpura that appears without cause and cracks that will not close all fit when the base is thin and undernourished. It is wrong for hot, red, weeping skin, and wrong where bleeding comes from Heat driving the Blood out rather than from deficiency. Unexplained, extensive or easy bruising needs medical assessment before it is treated as a deficiency pattern.
Actions
- Tonifies Qi
- Nourishes Blood
- Strengthens the Spleen
- Tonifies Heart Qi and Blood

- Holds Blood in the vessels
Properties

- Organs: Heart, Spleen
- Channels: Heart, Spleen, Liver
The pattern behind it
The root is Heart and Spleen deficiency from prolonged mental strain. The Spleen stops producing enough Blood and Qi, so the person tires, the skin pales and bruises appear; the Heart has too little Blood to house the spirit, so sleep breaks and the mind races. Treating both organs restores the production and the resting place of the spirit at once.

Patterns it treats
Heart and Spleen Qi and Blood Deficiency
Pale, thin, underfilled skin that bruises at a touch and heals slowly, sometimes dotted with small purpuric spots. The surface is short of Blood rather than inflamed, so it looks flat and drained of colour. The formula rebuilds the Qi and Blood that supply it.
How the formula is built
The formula pairs two jobs: building Qi and Blood so the body has material to work with, and calming the spirit so the Heart can rest. Mu Xiang is the small but important counterweight, keeping the sweet rich herbs from causing the bloating that would otherwise undo the treatment. The result is a tonic that can be taken for weeks without congesting.
Skin conditions it is used for
Where this formula appears in the skin conditions of the library.
Preparation and use
Decocted in water with ginger and dates, taken warm in two divided doses.
Modifications
- If insomnia dominates, the spirit-calming herbs are increased.
- If bleeding or bruising dominates, hemostatic herbs are added.
- If Cold is present, warming herbs are added.
- If the digestion is very weak, the rich herbs are reduced and the aromatic herbs increased.
Timing
Taken warm in two divided doses, often between meals.
Duration
Two to eight weeks for an acute presentation, and two to three months for chronic deficiency with periodic reassessment.
Diet while taking it
Warm cooked nourishing food; avoid cold, raw and greasy food that burdens the Spleen.
Safety
Contraindications
Avoid in Blood Heat patterns, where bleeding is caused by Heat driving Blood out rather than by deficiency: the warm tonics would worsen that. Use care in Dampness or Phlegm with a greasy coat.
Interactions
Gan Cao can cause potassium loss and raise blood pressure and interacts with diuretics, digoxin and corticosteroids. Ren Shen may affect blood sugar and anticoagulant therapy.
Pregnancy
Use with caution in pregnancy because Dang Gui has mild Blood-moving properties.
Breastfeeding
Considered acceptable under professional guidance.
Children
Used in children with reduced dose for deficiency with poor sleep and appetite.
Before you use it
Recorded from the classical record and rewritten in this project's own words. Educational only: not a prescription, and any unexplained bleeding or bruising needs medical assessment.

Origin and history
Ji Sheng Fang (济生方, Formulas to Aid the Living) by Yan Yonghe, Song dynasty, 1253; the fuller version with the spirit-calming herbs is recorded in later formularies.
Yan Yonghe published the formula in Ji Sheng Fang in 1253 for the consequences of excessive thinking: injury to the Heart and Spleen, with forgetfulness and palpitations. Later formularies added the spirit-calming herbs that are now standard, producing the version used today for the exhausted, pale, poor-sleeping patient whose skin bruises easily and heals slowly.
Evidence note
No controlled trial of this treatment in skin conditions was identified for this entry. What is described here rests on the classical and later materia medica record and on traditional clinical use, not on controlled trial evidence, and it is not a prediction of benefit. Where skin-specific research does exist it is linked above.
Common questions
Why is a sleep formula used for skin?
Because the same deficiency shows in both. A Spleen too weak to make Blood leaves the skin pale and easily bruised, and a Heart without enough Blood cannot rest, so sleep breaks. Treating the deficiency addresses both.
Is it suitable for active eczema?
No. It is warming and rich and is used after the acute phase, when the skin is pale, thin and slow-healing.
Why does it contain Mu Xiang?
To keep the sweet rich tonics moving. Without it, the formula can cause bloating and be poorly absorbed.
When should bruising be investigated?
Unexplained, extensive or easy bruising needs medical assessment, including blood tests, before it is treated as a deficiency pattern.
