Patterns Addressed
In TCM, symptoms don't appear randomly — they cluster into recognizable patterns of disharmony that reveal what's out of balance in the body. Yang Jing Zhong Yu Tang is designed to correct these specific patterns.
Why Yang Jing Zhong Yu Tang addresses this pattern
This formula directly addresses Liver and Kidney Yin deficiency by combining the most potent Yin-nourishing and Essence-filling herbs available. Shu Di Huang at heavy dosage replenishes Kidney Yin and Essence, while Shan Zhu Yu reinforces this action and astringes to prevent Essence leakage. Dang Gui and Bai Shao nourish Liver Blood, which shares a common source with Kidney Essence through the Liver-Kidney (Yi Gui Tong Yuan) relationship. Fu Qingzhu's original reasoning explains that the Kidney is the mother of the Liver. When the mother (Kidney) is depleted of Essence, it cannot nourish its child (Liver), leading to Liver Wood drying out and virtual Fire flaring. This formula restores the Kidney Water foundation so that Liver Blood naturally flourishes, the Chong and Ren vessels are nourished, and fertility can be restored.
A practitioner would look for one or more of these signs
Long-standing difficulty conceiving, especially in thin, constitutionally depleted women
Delayed periods with scanty flow, pale or dark-brown color
Dizziness and blurred vision from Blood and Essence failing to nourish the head
Soreness and weakness of the lower back and knees from Kidney depletion
Profound exhaustion, especially after intercourse
Thin, emaciated body frame reflecting deep Yin-Blood deficiency
Why Yang Jing Zhong Yu Tang addresses this pattern
Kidney Essence (Jing) is the fundamental substance governing reproduction, growth, and development. When Essence is depleted, the uterus lacks the material foundation to conceive and sustain pregnancy. This formula addresses Essence deficiency primarily through Shu Di Huang, the most important Essence-filling herb, supported by Shan Zhu Yu which both tonifies and astringes Kidney Essence. Dang Gui and Bai Shao contribute by nourishing Blood, which shares a mutual generative relationship with Essence. Fu Qingzhu stated that when Essence is full, the uterus can easily receive and hold, and when Blood is sufficient, the uterus can easily nurture, both being pathways to conception.
A practitioner would look for one or more of these signs
Inability to conceive despite prolonged attempts
Scanty or absent menstruation from Essence failing to transform into Blood
Dry mouth and throat from Yin fluids failing to rise
Restless sleep with heat sensation from Yin deficiency generating Empty Fire
Commonly Prescribed For
These conditions can arise from the patterns above. A practitioner would consider Yang Jing Zhong Yu Tang when these conditions are specifically caused by those patterns — not for all cases of these conditions.
TCM Interpretation
In TCM, fertility depends on the fullness of Kidney Essence and the nourishment of the Chong (Penetrating) and Ren (Conception) vessels, which are the two extraordinary vessels most directly connected to reproductive function. When Kidney Yin and Essence are depleted, the uterus lacks the material foundation to receive and sustain new life. Simultaneously, when Liver Blood is insufficient, the menstrual cycle becomes irregular and scanty, further reducing the window for conception. Fu Qingzhu identified a specific pattern where thin, constitutionally depleted women develop a vicious cycle: Kidney Essence depletion leads to Liver Wood drying out (since the Kidney is the mother of the Liver), which generates virtual Fire that further consumes the remaining Yin and Blood. This self-reinforcing depletion must be interrupted by powerfully replenishing the Kidney Water foundation.
Why Yang Jing Zhong Yu Tang Helps
Yang Jing Zhong Yu Tang breaks the depletion cycle by flooding the system with rich, nourishing substances. Shu Di Huang at 30g is one of the heaviest Essence-filling dosages in classical gynecology, directly rebuilding the Kidney Yin and Essence foundation. Shan Zhu Yu reinforces this while preventing Essence leakage with its astringent property. Dang Gui and Bai Shao restore Liver Blood and regulate menstruation, ensuring the Chong and Ren vessels receive adequate nourishment. Modern research has shown that this formula can regulate FSH and LH hormone levels, promote follicle development and maturation, and enhance ovulation. Animal studies demonstrate that it improves ovarian reserve function through the PI3K/AKT signaling pathway, promoting endometrial angiogenesis and repair.
TCM Interpretation
Diminished ovarian reserve (DOR) corresponds in TCM to premature decline of Kidney Essence, often called Tian Gui (the Kidney-derived substance that governs reproductive maturation). When Tian Gui wanes prematurely, follicle numbers decrease and reproductive capacity declines. The Kidney governs reproduction and stores Essence, and the ovaries are considered to be functionally connected to the Kidney system. Liver Blood insufficiency compounds the problem by failing to nourish the Chong vessel, which directly supplies the uterus and reproductive organs.
Why Yang Jing Zhong Yu Tang Helps
This formula's heavy emphasis on Essence-filling (through Shu Di Huang and Shan Zhu Yu) directly targets the root mechanism of DOR. Modern experimental research has validated this traditional application: studies show that Yang Jing Zhong Yu Tang can improve hormone levels by increasing AMH and estradiol while decreasing FSH and LH, promote follicular development, and improve ovarian tissue structure. Its mechanism has been linked to regulation of the Rictor/mTORC2 pathway and PI3K/AKT signaling, which affect follicle activation, granulosa cell survival, and ovarian function. Dang Gui and Bai Shao contribute by improving Blood circulation to the reproductive organs.

How It Addresses the Root Cause
TCM doesn't just suppress symptoms — it aims to resolve the underlying imbalance. Here's how Yang Jing Zhong Yu Tang works at the root level.
This formula addresses a specific pattern of infertility rooted in depletion of the Liver and Kidney systems. In TCM, the Kidneys store Essence (Jing), which is the fundamental material basis for reproduction. The Liver stores Blood. These two organs share a deep relationship often called "Liver and Kidney share the same source" (肝肾同源): Kidney Essence transforms into Liver Blood, and Liver Blood in turn nourishes and replenishes Kidney Essence.
In the pattern this formula treats, the woman's body is thin and constitutionally depleted. Kidney Essence is insufficient, which means the "mother" organ (Kidney is the mother of Liver in Five Phase theory) cannot nourish its "child." The Liver becomes dry and depleted of Blood. This creates a vicious cycle: with insufficient Kidney Water to anchor it, deficiency Fire rises — a flickering, false Heat that further scorches the remaining Yin fluids. The original text describes this as "Fire above Water" (an unfavorable hexagram), where the cooling, nourishing influence of Water cannot keep the rising Fire in check. This deficiency Fire manifests as irritability, dry mouth and throat, flushed cheeks, and a racing or thin pulse.
Because the Chong (Penetrating) and Ren (Conception) vessels — the two extraordinary meridians most directly governing menstruation and fertility — are rooted in Kidney Essence and nourished by Liver Blood, their depletion leads to scanty menstruation, delayed periods, and ultimately failure to conceive. The uterus, starved of both Essence and Blood, cannot provide a receptive environment for conception. The treatment strategy is therefore to heavily replenish Kidney Essence and Liver Blood. As Fu Qing-Zhu wrote: when Water is abundant, Blood is abundant; when Blood is abundant, the deficiency Fire naturally subsides, and the body returns to a state of harmonious balance where conception becomes possible.
