What Fu Yuan Huo Xue Tang is for
This formula was written for injury, and the skin shows it plainly: a dusky, swollen, tight area after a blow, with purple bruising and pain that stays in one place and worsens on pressure. The picture is trapped Blood rather than Heat, and the colour, the swelling and the fixed pain arrive together. It is a formula for the acute days, at its most useful before the bruise has had time to settle.
The skin over the injured area is dusky or purple, swollen and tight, and in the first days the colour does not shift with warmth or with time. Pressing it hurts in one fixed spot rather than diffusely, and the surface can look shiny from the swelling. Where the blow landed on the chest, ribs or upper body, the tightness spreads beyond the visible bruise.
Chai Hu reaches the chest and ribs and frees the Qi that the congestion has blocked, so the tissue can move again. Tao Ren, Hong Hua, Chuan Shan Jia and Dang Gui break the stagnant Blood, and Da Huang in a large dose clears the congestion downward, the formula's distinctive move. Tian Hua Fen cools and supports the tissue as it recovers, and Gan Cao harmonises. The bruise fades from the inside out rather than from the edge in.
It is used in the acute days after injury and not for old chronic stasis of other causes, and it is contraindicated in pregnancy. Any significant injury, especially with deformity or severe pain, needs medical assessment before herbal treatment, because the formula clears congestion and cannot rule out structural damage. It is stopped as soon as the pain eases and the bruise begins to change.
Actions
- Invigorates Blood and breaks stasis
- Clears stagnation downward
- Relieves pain and swelling from injury
- Restores the movement of Qi and Blood in the chest
Properties
- Taste and temperature: Predominantly bitter and pungent with a cold quality. Bitter clears and purges, pungent moves Blood.
- Organs: Liver, Heart, Large Intestine
- Channels: Liver, Heart, Large Intestine
The pattern behind it
The pattern is Blood stasis from trauma. The extravasated Blood congests the tissue and produces fixed pain, swelling and bruising, and because the congestion sits in the chest and ribs it also obstructs Qi. The formula breaks the stasis, moves the Qi and clears the congestion downward.
Composition
The herbs in Fu Yuan Huo Xue Tang, with their role and dose.
| Role | Herb | Dose | Properties | Why it is there |
|---|---|---|---|---|
| Da Huang | 15 to 30 g | Cold, Bitter | In a large dose it clears stagnant Blood downward through the bowel, the formula's distinctive move. | |
| King | Chai Hu | 9 to 15 g | Slightly cool, Pungent, bitter | Reaches the chest and ribs and moves the Qi that the stasis has obstructed. |
| Tao Ren | 9 to 15 g | Neutral, Bitter, sweet | Breaks Blood stasis, the base of the moving group. | |
| Hong Hua | 3 to 6 g | Warm, Pungent | Moves Blood and opens the vessels. | |
| Chuan Shan Jia | 3 to 6 g | Slightly cold, Salty | Penetrates and unblocks the channels, reaching stasis that ordinary moving herbs miss. | |
| Dang Gui | 6 to 9 g | Warm, Sweet, pungent | Nourishes and moves Blood, so the breaking does not deplete. | |
| Envoy | Tian Hua Fen | 6 to 9 g | Cool, Sweet, slightly bitter | Clears Heat and supports the tissue, helping the injured area recover. |
| Gan Cao | 3 to 6 g | Neutral, Sweet | Harmonises the formula. |
Patterns it treats
Blood Stagnation
Dusky, purple, swollen skin that is tight and painful in one fixed spot after a blow, with bruising that does not shift in the first days. Blood has left the vessels and congested the tissue, which is why the colour, the swelling and the fixed pain arrive together.
How the formula is built
The formula combines strong Blood-breaking with a purgative, which is unusual and effective for acute injury: the stasis is broken and the congestion is cleared downward. Chai Hu adds the Qi movement needed for the chest and ribs, and Tian Hua Fen supports the tissue as it recovers.
Skin conditions it is used for
Where this formula appears in the skin conditions of the library.
Preparation and use
Decocted in water and taken warm, usually with a little wine, in two divided doses.
Modifications
- If the pain is severe, more moving herbs are added.
- If the bruising is extensive, the stasis group is increased.
- If the person is depleted, the course is shortened and support added.
- If there is no constipation, the purgative is reduced.
Timing
Taken warm in two divided doses, usually with a little wine.
Duration
Acute use only: three to seven days, stopped as soon as the pain improves and the bowel moves.
Diet while taking it
Avoid cold raw food; increase fluids while the bowel is being purged.
Safety
Contraindications
Contraindicated in pregnancy. Avoid in chronic stasis without injury, in depleted patients, and in anyone with active bleeding.

Origin and history
Yi Xue Fa Ming (医学发明, Exposition of Medicine) by Li Dongyuan, Jin dynasty, 13th century.
The formula appears in Li Dongyuan's exposition of medicine as a treatment for injury to the chest and ribs. Its combination of strong Blood-breaking herbs with a large dose of purgative reflects the recognition that acute injury produces congestion that is best cleared quickly rather than slowly.
Classical record
Li Dongyuan recorded the formula for Blood stasis after injury in the chest and ribs, breaking the stasis and clearing the congestion downward with rhubarb.

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 does an injury formula contain a purgative?
Because after injury the stagnant Blood congests the tissue, and Da Huang clears that congestion downward. It is a quick, short-term measure.
Is it safe in pregnancy?
No. It is explicitly prohibited in pregnancy because of the strong Blood-moving herbs and the purgative.
How long is it used?
Three to seven days, stopped once the pain improves and the bowel moves.
Should an injury be assessed first?
Yes. Significant injury, especially with deformity or severe pain, needs medical assessment before herbal treatment.
