What Yi Guan Jian is for
The skin this formula is for is dry and reactive: it stings or reddens where it is rubbed, and it flares into a patchy rash when tension rises. The surface is short of moisture, but the trouble is not only dryness, because the tissue also looks tight and held. The formula restores the Yin the Liver needs to stay smooth and adds a single gentle herb to release the constraint that keeps the flare going.
The picture is a surface that is both dry and easily provoked: fine flaking over the cheeks and the sides of the face, a tight feeling after washing, and patches that redden and itch when the person is under pressure and settle again when it passes. The skin is not swollen and does not weep, and between flares it looks merely thin and dry. The changeability is the clue: a fixed lesion points elsewhere, while a surface that reacts to tension points at constraint on top of the dryness.
Sheng Di Huang, Bei Sha Shen, Mai Dong and Gou Qi Zi are the moistening group, rebuilding the Yin and the fluids that keep tissue supple, and Dang Gui gives the surface Blood to work with. Chuan Lian Zi is the only moving herb and it is deliberately small: enough to free the constrained Qi that drives the flare, not enough to dry the tissue further. Most herbs that move Qi are drying, which is why this formula moves very little and moistens a great deal.
It is the longer, quieter kind of treatment, taken over weeks, because Yin is rebuilt slowly and the reactivity settles after the moisture returns. It is not for Dampness or Phlegm with a greasy coat, where moistening herbs would congest the tissue, and it is not for cold deficiency. A rash that keeps flaring in one fixed place, or that is changing, needs medical assessment rather than another course.
Actions
- Nourishes Liver Yin
- Nourishes Blood and fluids
- Gently frees the Liver Qi
- Moistens dryness and soothes constraint
Properties
- Taste and temperature: Predominantly sweet with a mild bitter note. Sweet and moistening nourish Yin, the small bitter addition frees the Qi.
- Organs: Liver, Kidney, Stomach
- Channels: Liver, Kidney, Stomach
The pattern behind it
The pattern is Liver Yin and Blood deficiency with Qi constraint. The lack of moisture leaves the Liver unable to work smoothly, so it becomes constrained, and the constraint produces irritability and stress-linked flares. The formula restores the moisture and frees the Qi gently.
Composition
The herbs in Yi Guan Jian, with their role and dose.
| Role | Herb | Dose | Properties | Why it is there |
|---|---|---|---|---|
| King | Sheng Di Huang | 18 to 30 g | Cold, Sweet, bitter | Nourishes Yin and Blood deeply, the main moistening herb. |
| Dang Gui | 9 to 12 g | Warm, Sweet, pungent | Nourishes Blood and moves it gently, supporting the Liver. | |
| Gou Qi Zi | 9 to 18 g | Neutral, Sweet | Nourishes Liver and Kidney Yin and Blood. | |
| Bei Sha Shen | 9 to 12 g | Slightly cold, Sweet | Nourishes Stomach and Lung Yin gently, adding moisture without heaviness. | |
| Assistant | Mai Dong | 9 to 12 g | Slightly cold, Sweet, bitter | Moistens and generates fluids, supporting the Yin. |
| Chuan Lian Zi | 4.5 to 6 g | Cold, Bitter | Frees Liver Qi gently without drying, the small movement in an otherwise moistening formula. |
Patterns it treats
Liver Yin Deficiency
Dry, thin, reactive skin with fine flaking that reddens and stings when tension rises and settles again when it passes. The Yin that keeps the Liver smooth is low, so constraint builds and shows on the surface as a changeable, easily provoked rash.
How the formula is built
Five moistening herbs and one small Qi-moving herb. The proportion is the point: the formula nourishes without becoming cloying because of the single freeing herb, and it frees without drying because the moistening group dominates.
Skin conditions it is used for

Origin and history
Xu Ming Yi Lei An (续名医类案) by Wei Zhixiu, Qing dynasty, 18th century.
Yi Guan Jian comes from an 18th century Qing collection and is prized for solving a difficult combination: nourishing a dry Liver while freeing its constraint. That balance is why it is used for dry, sensitive, stress-responsive skin rather than for simple dryness.
Classical record
Wei Zhixiu recorded the formula for Liver Yin deficiency with constraint, nourishing the Yin and freeing the Qi gently so the Liver could function smoothly again.

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 only one Qi-moving herb?
Because most Qi-moving herbs are drying, which would worsen the Yin deficiency. One gentle herb is enough to free the constraint without drying.
Can it help stress-related skin flares?
Where the pattern is Liver Yin deficiency with constraint and dryness, it can be part of the treatment.
Who should avoid it?
People with Dampness and a greasy tongue coat, because the moistening herbs can congest.
How long does it take?
Weeks to months, because Yin rebuilds slowly.
