Chronic Kidney Disease and TCM: Can Herbs Help?

Understanding kidney health through the wisdom of Chinese medicine and modern research

Chronic kidney disease (CKD) affects millions of people, often developing gradually and without noticeable symptoms. By the time symptoms appear, kidney function may already be significantly reduced.

Although modern medicine has developed important treatments to slow the progression of kidney disease, many people are interested in whether Traditional Chinese Medicine (TCM) can offer additional support.

Chinese medicine has treated conditions involving weakness, fluid retention, urinary problems, and declining vitality for centuries. Today, researchers are examining whether certain Chinese herbs and formulas might also help protect kidney function.

The answer is encouraging in some respects, but complicated. Certain Chinese herbs have shown promising results in clinical studies, although stronger research is needed to establish their long-term benefits and safety.

What Is Chronic Kidney Disease?

The kidneys perform several essential functions:

• Filter waste products from the bloodstream.

• Regulate fluid and electrolyte balance.

• Help control blood pressure.

• Support healthy red blood cell production.

• Maintain the balance of minerals needed for healthy bones.

Chronic kidney disease occurs when abnormalities in kidney structure or function persist for at least three months.

The most common causes include diabetes and high blood pressure. Other causes include autoimmune disease, hereditary conditions, recurrent kidney infections, and certain medications.

Physicians generally evaluate CKD using two important measurements:

eGFR (estimated glomerular filtration rate): An estimate of how efficiently the kidneys filter the blood.

Urine albumin-to-creatinine ratio (uACR): A measurement of albumin leaking into the urine, which can indicate kidney damage.

These measurements help determine the severity of CKD and the likelihood of progression.

The Chinese Medicine Understanding of Kidney Disease

In Chinese medicine, the Kidneys are considered the foundation of Yin and Yang and the repository of Jing, or Essence.

However, an important distinction must be made: the TCM concept of the Kidneys is not identical to the anatomical kidneys described in modern medicine.

The TCM Kidney system encompasses functions associated with growth, reproduction, aging, fluid metabolism, and the maintenance of vitality.

Consequently, a diagnosis of Kidney deficiency in Chinese medicine does not necessarily indicate chronic kidney disease. Likewise, a patient with medically diagnosed CKD may have several different TCM patterns.

Rather than treating every patient with the same formula, Chinese medicine attempts to identify the pattern of imbalance associated with each person's condition.

1. Kidney Yin Deficiency

Kidney Yin represents the body's cooling, moistening, and nourishing functions.

Possible symptoms include:

• Dry mouth, especially at night

• Night sweats

• Feeling unusually warm in the evening

• Lower back or knee weakness

• Restlessness and disturbed sleep

• Dizziness or tinnitus

The traditional treatment principle is to nourish Kidney Yin.

Commonly considered formula: Liu Wei Di Huang Wan (Six Flavor Rehmannia Formula).

This classical formula contains Shu Di Huang, Shan Zhu Yu, Shan Yao, Ze Xie, Mu Dan Pi, and Fu Ling.

It is traditionally used for patterns involving Kidney Yin deficiency. However, its suitability for a patient with CKD requires an individualized assessment, and its ability to slow CKD progression has not been established.

2. Kidney Yang Deficiency

Kidney Yang represents the body's warming, transforming, and activating functions.

Possible symptoms include:

• Feeling cold, particularly in the lower body

• Fatigue and reduced vitality

• Weakness or soreness of the lower back

• Frequent urination

• Fluid retention

• Loose stools

The traditional treatment principle is to warm and support Kidney Yang while promoting appropriate fluid metabolism.

Commonly considered formula: Jin Gui Shen Qi Wan (Kidney Qi Pill from the Golden Cabinet).

This formula builds upon Liu Wei Di Huang Wan with warming herbs. Classical versions include Fu Zi, which requires specialized processing and careful professional supervision because of its potential toxicity.

Jin Gui Shen Qi Wan should not be regarded as a general-purpose treatment for impaired kidney function.

3. Spleen and Kidney Qi Deficiency

In TCM, the Spleen is responsible for transforming food into Qi and supporting the movement of fluids throughout the body.

The Kidneys provide an essential foundation for these functions.

When both systems are deficient, symptoms may include:

• Persistent fatigue

• Poor appetite

• Abdominal bloating

• Weakness

• Loose stools

• Swelling of the lower extremities

Treatment traditionally focuses on supporting Qi, strengthening digestion, and restoring healthy fluid metabolism.

Herbs such as Huang Qi (Astragalus) and Dang Shen (Codonopsis) are frequently considered for Qi-deficient patterns.

However, swelling in someone with CKD may reflect clinically important fluid overload and should not be treated solely as a TCM imbalance.

4. Dampness and Blood Stasis

In more complicated or longstanding conditions, Chinese medicine may identify Dampness, Turbidity, or Blood Stasis.

Dampness is traditionally associated with impaired fluid transformation, while Blood Stasis refers to impaired circulation within the TCM diagnostic framework.

Practitioners may consider these patterns when patients experience swelling, a sense of heaviness, or other persistent symptoms.

Treatment might involve herbs traditionally described as transforming Dampness, promoting urination, or invigorating Blood.

However, these traditional concepts are not equivalent to modern diagnoses such as kidney fibrosis, proteinuria, or reduced renal blood flow. Herbs selected for these patterns require particular caution when kidney function is impaired.

Chinese Herbs Being Studied for Kidney Disease

Several Chinese medicinal substances have attracted scientific interest.

Huang Qi (Astragalus Root)

Huang Qi is among the most widely studied Chinese herbs for chronic kidney disease.

In TCM, it is traditionally used to strengthen Qi and support the body's defensive functions.

Researchers have examined its possible effects on:

• Urinary protein loss

• Kidney filtration measurements

• Inflammatory processes

• Complications associated with CKD

A Cochrane review of 22 studies involving 1,323 participants reported potentially favorable results when Astragalus was added to conventional treatment.

However, the researchers emphasized that the studies were generally of low quality, making definitive conclusions impossible.

Astragalus is therefore a subject of legitimate scientific interest, but it is not a proven treatment for preventing kidney failure.

Dong Chong Xia Cao (Cordyceps)

Cordyceps has traditionally been used to tonify Kidney and Lung functions.

Modern researchers have investigated whether Cordyceps preparations may influence kidney function, proteinuria, and complications associated with CKD.

A Cochrane review involving 22 studies and 1,746 participants found potentially beneficial changes in several laboratory measurements when Cordyceps was used alongside conventional care.

However, methodological weaknesses limited the reliability of these findings.

Different commercial Cordyceps products can also vary considerably in composition.

Fu Ling (Poria)

Fu Ling is traditionally used to promote fluid metabolism, strengthen the Spleen, and calm the Spirit.

It appears in numerous classical formulas, including Liu Wei Di Huang Wan.

Within TCM, it may be selected when fatigue, poor digestion, and fluid accumulation occur together.

However, its traditional reputation for promoting urination does not establish that it improves kidney filtration or treats kidney failure.

Shan Yao (Chinese Yam)

Shan Yao is traditionally used to tonify Spleen and Kidney Qi and nourish Yin.

It appears in many formulas for chronic weakness and deficiency patterns.

Its mild traditional properties make it an important herb in Chinese medicine, although there is insufficient clinical evidence that it independently slows chronic kidney disease.

Can Chinese Herbs Prevent Kidney Failure?

This is perhaps the most important question.

Some studies suggest that particular herbal preparations may reduce proteinuria or improve measurements such as serum creatinine.

These findings are worth investigating.

However, changes in laboratory measurements do not necessarily demonstrate that an herb prevents dialysis, transplantation, or kidney failure.

Clinical studies must establish that a treatment produces meaningful, lasting benefits without unacceptable risks.

At present, there is insufficient high-quality evidence to conclude that Chinese herbal treatment reliably prevents progression to kidney failure.

The most reasonable approach is to investigate TCM as a carefully monitored complement to established kidney care rather than a replacement for it.

Are Chinese Herbs Safe for People With Kidney Disease?

Safety requires special attention when kidney function is reduced.

Healthy kidneys help eliminate numerous substances from the bloodstream. When filtration declines, certain compounds or minerals may accumulate.

Several concerns deserve attention.

Correct identification and quality: Herbal ingredients should be botanically authenticated, properly processed, and obtained from reliable suppliers.

Aristolochic acid: Exposure to aristolochic acids has been associated with serious kidney injury and urinary tract cancers. Historical cases involved herb misidentification or substitution, among other exposure circumstances. These incidents underscore the importance of accurate botanical identification. Aristolochic acid itself has established nephrotoxic properties.

Interactions with medication: Some herbal ingredients may affect blood pressure, electrolyte balance, drug metabolism, or bleeding risk. The clinical significance depends on the actual formula, dose, preparation, and medication involved.

Mineral accumulation: Certain herbs, mineral substances, or supplements may contain substantial amounts of potassium or other minerals that become problematic in advanced CKD.

Individualized prescribing: An herb appropriate for someone with normal kidney function may be unsuitable for a person with significant renal impairment.

Herbal medicines should never be assumed safe simply because they are natural. At the same time, evidence of toxicity from a particular substance, preparation, or dosage should not automatically be generalized to every Chinese medicinal herb.

The most useful safety evaluation considers the actual ingredients, botanical identity, preparation, human evidence, dosage, and patient's kidney function.

For patients with CKD, any medicinal herbal formula should be reviewed by the treating kidney specialist and a qualified TCM practitioner before use.

 

Lifestyle: Where Chinese Medicine and Modern Medicine Meet

Both Chinese medicine and modern nephrology recognize the importance of daily habits in maintaining health.

Several measures are especially important for people with chronic kidney disease.

Control Blood Pressure and Blood Sugar

Diabetes and hypertension are among the leading causes of chronic kidney disease.

Appropriate medical treatment of these conditions is one of the most effective ways to protect remaining kidney function.

Eat According to Your Individual Needs

In TCM, dietary recommendations depend on the patient's constitution and pattern of imbalance.

Modern kidney nutrition also requires individualization.

Some patients need to limit sodium, potassium, phosphorus, or dietary protein, while others do not require all of these restrictions.

A renal dietitian can help prevent unnecessary dietary limitations and poor nutrition.

Stay Physically Active

Gentle exercise, walking, tai chi, and qigong may help support cardiovascular health, strength, and overall well-being.

These activities can be adapted to the person's physical abilities.

Avoid Unnecessary Kidney Stress

Certain medications, particularly nonsteroidal anti-inflammatory drugs such as ibuprofen and naproxen, can worsen kidney function in susceptible patients.

Avoiding dehydration and reviewing medications and supplements with a healthcare professional are also important.

People with advanced CKD or heart failure should follow individualized fluid recommendations rather than simply increasing water intake.

 

Combining Chinese Medicine With Conventional Kidney Care

The most promising approach is not to choose between Chinese medicine and modern medicine.

Modern nephrology offers treatments that can substantially reduce the risk of kidney failure in appropriate patients. These include blood pressure management, certain medications that reduce urinary protein loss, and drugs such as SGLT2 inhibitors.

Chinese medicine offers a different perspective that considers the patient's overall condition, symptom patterns, and constitutional characteristics.

A responsible integrative approach may combine conventional treatment, individualized symptom management, carefully evaluated herbal medicine when appropriate, dietary guidance, and continuing laboratory monitoring.

The Bottom Line

Traditional Chinese Medicine offers a sophisticated historical framework for understanding patterns of weakness, fluid imbalance, and chronic illness.

Certain Chinese herbs, especially Astragalus and Cordyceps, have produced interesting results in clinical research involving chronic kidney disease.

However, the evidence remains too limited to recommend these substances as proven treatments for preventing kidney failure.

For people living with CKD, the best approach is individualized care that respects both traditional knowledge and modern scientific findings.

The goal is not simply to improve symptoms, but to preserve kidney function, reduce complications, and maintain the best possible quality of life.

At Shen Clinic, we believe that traditional knowledge and contemporary medical science can inform one another. Thoughtful integration requires accurate diagnosis, appropriately selected treatments, attention to safety, and continuing evaluation.
