What Liu Wei Di Huang Wan is for
The skin here is dry, thin and inelastic, with pigment that reads as age rather than as inflammation, and hair that thins or greys early. The explanation is a low Kidney Yin, the deep reserve of moisture and substance the whole body draws on, and the formula refills that reserve rather than treating the surface. It is used over months of slow change rather than for an acute rash.
The picture is depletion rather than inflammation. The skin is dry and thin, loses its elasticity, and fine cracks appear where it is thinnest. The colour is dull rather than red, pigmentation settles in patches that look like age, and hair may thin or grey early. Nothing about the surface is angry: it does not flush or weep, and the formula is not a moisturiser, because the shortage it expresses is internal. It is the dry phase of a long process rather than a flare, and it is judged over weeks and months.
The tradition locates the cause in the Kidney Yin, so the formula fills that store. Shu Di Huang is the leading herb, filling the deepest reserve; Shan Zhu Yu and Shan Yao secure the Essence so what is built is not lost; Ze Xie, Mu Dan Pi and Fu Ling drain a little Dampness so the rich tonics do not stagnate, and Mu Dan Pi also cools the mild heat that deficiency produces. Three herbs fill and three drain. That balance is what allows a rich formula to be taken for months without congestion, and it is why the suppleness of the skin is treated as a slow internal restoration rather than a surface repair.
It suits chronic dryness on a depleted base, such as the dry phase of eczema or pigmentation that has come with age, and it is not for an active red or weeping rash. Kidney Yang deficiency is excluded: a pale, cold, dry surface that wants warmth belongs to the opposite pattern, and the cooling richness would make it worse. Damp-Heat with a greasy yellow coat is excluded too, because the richness would add to the congestion.

- Organs: Kidney, Liver, Spleen
- Channels: Kidney, Liver, Spleen
The pattern behind it
The root is deficient Kidney Yin, the body's deep reserve of moisture and cooling. When it is low the skin loses its suppleness, the hair loses its nourishment, and a low-grade heat develops because the warming side is no longer balanced. The formula refills the reserve rather than treating the dryness from outside.
Composition
The herbs in Liu Wei Di Huang Wan, with their role and dose.
| Role | Herb | Dose | Properties | Why it is there |
|---|---|---|---|---|
| King | Shu Di Huang | 24 g | Slightly warm, Sweet | The central Yin and Blood tonic, filling the deepest reserve. |
| Shan Zhu Yu | 12 g | Slightly warm, Sour, astringent | Secures the Essence and astringes, so what is built is not lost. | |
| Shan Yao | 12 g | Neutral, Sweet | Tonifies the Spleen and Kidney together, supporting both production and storage. | |
| Ze Xie | 9 g | Cold, Sweet, bland | Drains Dampness downward, preventing the rich tonics from congesting. | |
| Mu Dan Pi | 9 g | Slightly cold, Bitter, pungent | Cools the Blood and clears mild deficiency heat while moving it. | |
| Fu Ling | 9 g | Neutral, Sweet, bland | Supports the Spleen and drains Dampness gently, balancing the tonics. |
Patterns it treats
Yin Deficiency
Dry, thin and inelastic skin with a dull rather than red colour, fine cracking and pigmentation that reads as age. The moisture and substance are low at the deepest level, so the surface cannot hold its suppleness.
How the formula is built
Three herbs fill and three drain. Shu Di Huang, Shan Zhu Yu and Shan Yao rebuild and secure the Yin and Essence; Ze Xie, Mu Dan Pi and Fu Ling prevent the richness from causing stagnation and clear the small amount of heat that deficiency produces. That balance is why the formula can be taken for months, and why it is the base from which the other Rehmannia formulas are built.
Skin conditions it is used for
Where this formula appears in the skin conditions of the library.
Preparation and use
Taken as prepared pills, traditionally with lightly salted warm water, two to three times a day.
Modifications
- If heat signs appear, the formula is combined with cooling herbs, as in Zhi Bai Di Huang Wan.
- If the eyes and dryness dominate, eye-nourishing herbs are added.
- If the digestion is weak, the pills are taken after food or in reduced dose.
- Where dryness of the Lungs is prominent, Lung-moistening herbs are added.
Timing
Traditionally taken with lightly salted warm water, two to three times a day.
Duration
Typically four to eight weeks as a course, then reassessed; intermittent courses are used for chronic deficiency.
Diet while taking it
Avoid drying food: alcohol, fried food and heavy spice. Moistening food supports the treatment.
Safety
Contraindications
Avoid in Kidney Yang deficiency: cold limbs, pale complexion, aversion to cold, cold lower back and copious pale urine. Avoid in Damp-Heat with a greasy yellow tongue coat, where the richness would add to the congestion.
Interactions
The formula may affect blood sugar and should be monitored in diabetes. It can also add to the effect of diuretics through Ze Xie and Fu Ling.
Pregnancy
Generally considered relatively safe in pregnancy under professional guidance for confirmed Kidney Yin deficiency, as it contains no strongly moving or descending herbs.
Breastfeeding
Considered acceptable under professional guidance.
Children
Used in children with reduced dose, and historically the formula originated in paediatric practice.

Origin and history
Xiao Er Yao Zheng Zhi Jue (小儿药证直诀, Key to Therapeutics of Children's Diseases) by Qian Yi, Song dynasty, around 1119 CE.
Qian Yi created the formula in the Song dynasty for children with weak constitution and delayed development, based on the principle of filling the Kidney Yin. It was later adopted for adults, became the foundation of the Rehmannia family of formulas, and remains one of the most widely used tonics for the dry, depleted, ageing picture including the skin.
Classical record
The formula was created for children with delayed development and weak constitution, from the idea of filling the Kidney Yin to support growth, and was later adopted for adults with Yin deficiency and dryness.

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
Is this the same as Zhi Bai Di Huang Wan?
No. Zhi Bai Di Huang Wan is this formula plus two cooling herbs, for deficiency with heat signs. This is the base formula, used when the deficiency is present without prominent flushing.
Can it help dry skin?
For dry thin skin on a depleted base, yes, over weeks. It is not a moisturiser and does not treat active inflammation.
Who should not take it?
Anyone who feels cold easily with cold limbs and copious pale urine, which is Yang deficiency, or anyone with a greasy yellow tongue coat from Damp-Heat.
Why does it contain draining herbs if it is a tonic?
Because rich tonics can congest. The three draining herbs keep the formula balanced so it can be taken for months without causing stagnation.
