What Shen Tong Zhu Yu Tang is for
This is the stasis formula for skin that has thickened, tightened or lost sensation over an area that has troubled the person for a long time. The change has built up slowly, so the tissue looks dusky and feels wooden rather than showing a fresh rash. The formula breaks the stasis, moves Qi so the Blood can follow, and reaches the fine collaterals where the thickening sits.
What shows on the surface is tissue that has lost its suppleness. The skin over the affected area is thickened, tight and often insensitive, sometimes dusky, and it may look slightly puffy without being hot. Damp weather makes the area worse, which is the Wind-Dampness component, and the change has been there long enough that ordinary measures have not shifted it. A purple or dusky tongue with dark sublingual veins is the confirming sign.
Hong Hua leads the group that breaks the stasis, with Tao Ren, Chuan Xiong, Dang Gui, Wu Ling Zhi and Mo Yao moving and nourishing Blood so the breaking does not deplete it; Xiang Fu moves Qi so the Blood has something to follow; Niu Xi draws the action down and strengthens the lower body; Qin Jiao and Qiang Huo clear the Wind-Dampness that keeps the area weather-sensitive; Di Long as envoy penetrates the fine collaterals where the thickening sits; Gan Cao harmonises. It brings a great deal of momentum to bear.
Its force is also its limit. It is contraindicated in pregnancy, and it is not for an acute injury or for pain that comes from deficiency without stasis, where the moving group would weaken tissue that is already thin. Where the person is depleted, supporting herbs have to be added. New or spreading tightness of the skin, or numbness that keeps extending, needs medical assessment before it is read as stasis.
Actions
- Invigorates Blood and dispels stasis
- Dispels Wind-Dampness
- Unblocks the channels and collaterals
- Relieves chronic body and limb pain
Properties
- Taste and temperature: Predominantly pungent, bitter and warm. Pungent and warm move Blood and dispel Cold, bitter dries Dampness, with aromatic notes to open the channels.
- Organs: Heart, Liver, Spleen
- Channels: Heart, Liver, Spleen
The pattern behind it
The pattern is Blood stasis combined with Wind-Dampness in the channels. The stasis produces the fixed, severe pain and the dusky colour; the Wind-Dampness produces the heaviness and the weather sensitivity. The formula breaks the stasis, dispels the Wind-Dampness and unblocks the collaterals, which is why it treats pain that has resisted simpler approaches.

| Chuan Xiong | 6 g | Warm, Pungent | Moves Qi and Blood, reaching the upper body and head. | |

| Mo Yao | 6 g | Neutral, Bitter, pungent | Moves Blood and relieves pain, working with the stasis-breaking group. | |
| Wu Ling Zhi | 6 g | Warm, Bitter, sweet | Breaks Blood stasis and relieves pain, particularly in the lower body. | |
| Xiang Fu | 3 g | Neutral, Pungent, bitter | Moves Qi so the Blood can move, addressing the Qi side of the stasis. | |

Patterns it treats
Blood Stagnation
Skin that has thickened, tightened and lost sensation over an area that has troubled the person for a long time, often dusky and worse in damp weather. The tissue feels wooden and the change has built up slowly.
How the formula is built
The formula brings a lot of force to bear on one problem. Nine herbs address stasis and pain, two dispel Wind-Dampness, one moves Qi and one reaches the collaterals. That concentration is why it is used for pain that has not responded to milder treatment, and why it must not be given to a depleted person without support.
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 lower body dominates, the lower-body herbs are increased.
- If Cold is marked, warming herbs are added.
- If the generalised weakness suggests deficiency, tonics must be added or the formula reduced.
- If Heat is present, cooling herbs are added and the warming reduced.
Timing
Taken warm in two divided doses.
Duration
Two to four weeks for an acute flare, and four to eight weeks for chronic pain, with reassessment.
Diet while taking it
Avoid cold and raw food, since Cold congeals Blood and opposes the moving action.
Safety
Contraindications
Avoid in pregnancy. Avoid in acute injury and in pain from deficiency without stasis. Use care in anyone who is depleted, because the formula is strongly moving.
Interactions
The Blood-moving herbs may add to anticoagulant and antiplatelet medication and increase bleeding risk. Di Long may also affect clotting.
Pregnancy
Contraindicated. Multiple herbs in the formula strongly move Blood and break stasis, including Tao Ren, Hong Hua and Niu Xi.
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 new or progressive pain, weakness or skin tightening needs medical assessment.

Origin and history
Yi Lin Gai Cuo (医林改错, Corrections of Errors among Physicians) by Wang Qingren, Qing dynasty, 1830.
Wang Qingren built a family of stasis formulas in 1830, each aimed at a different region. This is the body-pain member, and its combination of heavy stasis-breaking with Wind-Dampness herbs made it the formula for chronic pain that had resisted ordinary treatment. In skin work it is used for the thickened, insensitive tissue that long-standing stasis produces.
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
How does it differ from Xue Fu Zhu Yu Tang?
Xue Fu Zhu Yu Tang targets the chest. Shen Tong Zhu Yu Tang targets the body and limbs and adds herbs for Wind-Dampness, so it is used for widespread limb pain rather than chest stasis.
Can it help thickened skin?
Where the thickening comes from chronic stasis with a purple tongue and dusky tissue. Scleroderma and similar conditions need specialist care first.
Why is it contraindicated in pregnancy?
Because several herbs strongly move Blood and break stasis, which can stimulate the uterus.
How long is it used?
Two to four weeks for a flare, four to eight weeks for chronic pain with review.
