What Qiang Huo Sheng Shi Tang is for
This light, dispersing formula is for skin that has gone heavy and congested after damp or cold exposure. Nothing is red or hot: the surface looks dull and feels thick, and the weather makes it worse.
The picture is a dull, dusky surface that looks waterlogged rather than inflamed. The tissue feels heavy and slightly puffy, the colour is greyish or shadowed rather than red, and the skin can ache in a diffuse way that follows the weather. Damp cold makes it worse, while warmth and movement ease it. Where the tissue is loose, the congestion is most obvious. There is no heat in it and no dryness either: the surface simply looks and feels bogged down, as though fluid is sitting in the tissue and not moving.
The herbs are light and dispersing, and they lift that congestion out instead of draining it downward. Qiang Huo works on the upper body and Du Huo on the lower, so the whole surface is covered. Fang Feng releases the surface and eases the aching, Gao Ben reaches the head, and Man Jing Zi clears the head and the eyes so the upper region is not left congested. Chuan Xiong moves the Blood that the Dampness has slowed, which is what takes the dullness out of the colour, and Gan Cao harmonises the group.
Because the formula disperses, it is used in short courses, and it is not for skin that is red, hot and greasy, where the task is to clear rather than to lift. It is also not for depleted skin without support, since pure dispersing can leave a thin, dry surface worse. It suits the acute stage after damp or cold exposure, when the tissue is congested but the constitution is still strong, and the response should be visible within days rather than weeks.
Actions
- Dispels Wind-Dampness
- Relieves heavy headache and stiff neck
- Unblocks the surface and channels
- Clears congestion of the head

- Organs: Lungs, Spleen, Bladder
- Channels: Lung, Spleen, Bladder
The pattern behind it
The pattern is Wind-Dampness settling in the upper body and surface. The Dampness produces the heaviness and the greasy coat, the Wind produces the aching and the weather sensitivity, and together they congest the head and shoulders. The formula disperses them upward and outward.
Composition
The herbs in Qiang Huo Sheng Shi Tang, with their role and dose.
| Role | Herb | Dose | Properties | Why it is there |
|---|---|---|---|---|

Patterns it treats
Painful Obstruction with Wind-Cold-Damp
Dull, dusky, heavy-looking skin that feels thick and slightly puffy after damp or cold exposure, with aching that follows the weather. There is no redness or heat in it, which is what separates this congested surface picture from the hot, inflamed ones.
How the formula is built
Six dispersing herbs and one harmoniser. The formula is light and ascends, which is deliberate: Dampness in the upper body must be lifted out rather than drained downward, and the herbs reach the head and surface specifically.
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, in two divided doses.
Modifications
- If the Cold is marked, warming herbs are added.
- If the headache dominates, head-clearing herbs are increased.
- If the Dampness is heavy, draining herbs are added.
- If Heat is present, the warming is reduced.
Timing
Taken warm in two divided doses.
Duration
Short course: three to seven days, reassessed.
Diet while taking it
Warm food; avoid cold raw food and damp environments.
Safety
Contraindications
Avoid in Damp-Heat and in depleted patients without tonic support, since the formula is dispersing. Use in short courses.
Interactions
Gan Cao may interact with diuretics, digoxin and corticosteroids.
Pregnancy
Use with caution in pregnancy because the dispersing herbs are warming and mobilising.
Breastfeeding
Use only under professional guidance.
Children
Used only with professional supervision.
Before you use it
Recorded from the classical record and rewritten in this project's own words. Educational only: not a prescription, and persistent headache or neck stiffness needs medical assessment.

Origin and history
Pi Wei Lun (脾胃论, Treatise on the Spleen and Stomach) by Li Dongyuan, Jin dynasty, 13th century, recorded in later formularies.
Qiang Huo Sheng Shi Tang belongs to Li Dongyuan's approach to Dampness, where the upper body needed lifting rather than draining. Its light dispersing herbs made it the standard formula for the heavy head and stiff shoulders of damp exposure.
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
What is it used for?
A heavy aching head and stiff shoulders after damp exposure, with a greasy tongue coat.
How is it different from Juan Bi Tang?
Juan Bi Tang adds tonics for depleted patients. This formula is purely dispersing, for the acute damp pattern.
Can it help skin?
Only where congested dusky tissue accompanies the Wind-Dampness pattern.
How long is it used?
Three to seven days, reassessed.
