Zhen Wu Tang, or True Warrior Decoction, is a powerful Chinese herbal formula named after Zhenwu, the mythical northern water god who tames floods. Rooted in traditional Chinese medicine (TCM), this formula from Treatise on Febrile Diseases warms spleen and kidney yang, promotes urination, and clears dampness.
With just five herbs, it’s a go-to remedy for conditions like edema, fatigue, and dizziness caused by yang deficiency and fluid retention, offering both ancient wisdom and modern benefits.
What’s in Zhen Wu Tang?
Zhen Wu Tang combines five herbs, carefully balanced to restore warmth and fluid metabolism. The ingredients and their dosages are:
Poria (Fu Ling, 9g): Neutral and sweet, poria strengthens the spleen, promotes diuresis, and clears fluid buildup, reducing edema and dizziness.
White Peony Root (Bai Shao, 9g): Bitter and cooling, peony nourishes blood, soothes abdominal pain, and calms digestive discomfort.
White Atractylodes (Bai Zhu, 6g): Warm and bitter, atractylodes boosts spleen function, dries dampness, and supports digestion.
Ginger (Sheng Jiang, 9g): Warm and pungent, ginger warms the stomach, disperses cold, and relieves nausea or vomiting.
Aconite (Fu Zi, 9g): Hot and pungent, roasted and peeled aconite warms kidney yang, relieves limb coldness, and reduces pain (used safely in precise doses despite its toxicity).
Preparation
Decoct the herbs in water and drink warm as a tea, with dosages adjusted based on the patient’s condition.
How It Works
Zhen Wu Tang targets spleen and kidney yang deficiency with fluid retention, a TCM condition where weak yang (warmth and energy) impairs the spleen’s ability to transform fluids and the kidneys’ role in water metabolism.
This leads to dampness and water overflow, causing edema or digestive issues. Triggers include cold diets, overexertion, or chronic illness.
The formula works by:
Warming Yang: Aconite and ginger restore spleen and kidney warmth, boosting energy and fluid movement.
Promoting Diuresis: Poria and atractylodes clear dampness and excess fluid through urination.
Strengthening the Spleen: Atractylodes and poria enhance digestion, preventing further fluid buildup.
Soothing Digestion: Peony and ginger relieve abdominal pain, diarrhea, or vomiting.
This warms the body, clears fluid stagnation, and restores vitality, aligning with TCM’s focus on balancing yang and water.
What Does It Treat?
Zhen Wu Tang is used for yang deficiency with fluid retention, with symptoms including:
Cold limbs or chills
Swelling (edema), especially below the waist
Difficulty urinating
Dizziness or feeling unsteady
Heart palpitations or shortness of breath
Abdominal pain, diarrhea, or vomiting
Cough or wheezing
Heavy, painful limbs
Pale, fat tongue with white, greasy coating
Weak, slow, or fine pulse
These reflect water and dampness accumulating in the body, often affecting the limbs, intestines, lungs, or heart.
Modern Applications
Modern research highlights Zhen Wu Tang’s diuretic, anti-inflammatory, cardiotonic, and immunomodulatory effects, driven by its herbs’ bioactive compounds.
Clinical uses include:
Kidney Disorders: Reduces edema and proteinuria in chronic glomerulonephritis by enhancing kidney function.
Heart Conditions: Manages cardiogenic edema from heart failure, easing swelling and shortness of breath.
Thyroid Issues: Improves fatigue and edema in hypothyroidism by warming yang.
Respiratory Conditions: Relieves cough, phlegm, and breathing difficulties in chronic bronchitis.
Digestive Disorders: Treats chronic enteritis or intestinal tuberculosis by reducing diarrhea and abdominal pain.
The formula’s ability to warm and clear fluid makes it effective for conditions involving low metabolism, swelling, or cold-related symptoms.
Pathogenesis in TCM
In TCM, spleen and kidney yang deficiency disrupts water metabolism, leading to fluid retention. The spleen, responsible for transforming fluids, becomes “trapped” by dampness when yang is weak, causing bloating or edema.
The kidneys, which govern water, fail to transform fluids into qi, resulting in water overflow. This can manifest as:
Edema in the limbs (fluid in muscles).
Diarrhea or abdominal pain (fluid in intestines).
Cough or wheezing (fluid in lungs).
Palpitations (fluid affecting the heart).
Dizziness (fluid blocking clear yang).
Zhen Wu Tang warms yang, transforms fluids, and restores organ function to clear these issues.
Precautions
Aconite Toxicity: Aconite is potent and toxic if mishandled; use only under professional supervision with precise dosing.
Weak Constitutions: Those with frail health should use cautiously, monitored by a practitioner.
Pregnancy: Avoid in pregnant women due to aconite’s cardiotonic effects, which may impact the fetus.
Long-Term Use: Regular liver and kidney function checks are needed to prevent herb accumulation.
Professional Guidance: Consult a TCM practitioner to ensure proper diagnosis and tailored use.
Conclusion
Zhen Wu Tang is a remarkable Chinese herbal formula that warms spleen and kidney yang, clears fluid retention, and restores vitality. With poria, aconite, peony, ginger, and atractylodes, it effectively treats edema, dizziness, and digestive issues caused by yang deficiency.
Backed by modern research for its diuretic and anti-inflammatory benefits, it shines in treating kidney, heart, and respiratory conditions. When used under professional guidance, Zhen Wu Tang offers natural relief, blending TCM’s ancient wisdom with contemporary health solutions.

Pathogenesis | Zhen Wu Tang is the fundamental formula used to treat an overflow of water-dampness caused by deficiency of spleen-kidney yang. The spleen restricts water and the kidney governs water. Spleen yang deficiency leads to dysfunction of the transformation and transportation of water, while kidney yang deficiency leads to the dysfunction of dispersion and distribution of water. Both lead to water retention in the interior. Kidney yang deficiency leads to cold-water retention in the interior with urination disturbance. Furthermore, water-dampness spills over and diffuses into the limbs to cause heaviness and pain of the limbs and swelling of the body and limbs. Water-dampness pours downward into the bowels to cause abdominal pain and diarrhea. It rushes up to the lung and stomach to cause coughing and vomiting and when it invades the heart there are palpitations. Water-dampness blocks the middle jiao which inhibits the clear yang from rising and causes dizziness. If there is too much sweat loss that occurs when inducing sweat-promotion in a taiyang syndrome, yin and yang might be consumed. The result is a loss of warmth and fluid invasion into the muscles and tendons causing muscular twitching and unsteadiness while standing. For water overflowing due to yang deficiency, the therapeutic methods are to warm yang and promote urination. |
