Also known as: Hypertension During Pregnancy, Pre-eclampsia, Pregnancy-induced Hypertension, Toxemia Of Pregnancy, Pre Eclampsia, Gestational Hypertension, High Blood Pressure In Pregnancy
TCM sees preeclampsia not as one disease but as several distinct patterns - from Yin deficiency with surging Liver Yang to Spleen weakness flooding the tissues - and targeted herbal formulas can help stabilize blood pressure and reduce swelling, often within 2-4 weeks of consistent treatment alongside conventional care.

Preeclampsia is a pregnancy complication that usually begins after 20 weeks of gestation. It is defined by new-onset high blood pressure and signs of damage to other organ systems - most often the kidneys, which leak protein into the urine. Typical symptoms include severe headaches, vision changes like flashing lights or blurred sight, sudden swelling of the hands and face, and pain in the upper belly.
Western medicine diagnoses preeclampsia through repeated blood pressure readings and lab tests that check urine protein levels, liver enzymes, and platelet counts. Because it can progress rapidly and threaten both mother and baby, it is managed with close monitoring, blood pressure medications, and sometimes early delivery.
Conventional treatments
Standard management depends on how far along the pregnancy is and how severe the condition is. For mild cases, frequent monitoring of blood pressure and fetal well-being may be enough. When blood pressure rises, medications like labetalol or nifedipine are used to keep it in a safer range. If the disease worsens, magnesium sulfate is given to prevent seizures (eclampsia), and delivery of the baby and placenta is the only definitive cure - even if it means a preterm birth.
Where conventional treatment falls short
Blood pressure medications control the numbers but do not address the underlying placental dysfunction or the systemic inflammation that drives the disease. The only true resolution is delivery, which can force a difficult choice between maternal safety and fetal maturity. This creates a window of weeks where the mother needs support to stabilize her body and prolong the pregnancy safely - a window where TCM's pattern-based approach can offer meaningful complementary care by targeting the root imbalances that fuel the condition.
How TCM understands preeclampsia
「妊娠有水气，身重，小便不利，洒淅恶寒，起即头眩，葵子茯苓散主之。」
"During pregnancy there is water qi: the body feels heavy, urination is difficult, there is shivering and aversion to cold, and dizziness upon rising. This is treated with Kui Zi Fu Ling San. This passage describes a condition of fluid retention with edema, heaviness, and dizziness that closely resembles preeclampsia."
How a TCM practitioner diagnoses preeclampsia
Inside the consultation
A TCM practitioner begins by asking about the nature of your dizziness, swelling, and blood pressure changes. They want to know if the headache is dull and empty-feeling or sharp and pounding, whether swelling is puffy all over or just in the ankles, and if you feel irritable, heavy, or breathless. The answers point toward an underlying pattern of imbalance.
If dizziness and a flushed face come with night sweats, a dry mouth, and a feeling of heat in the palms and soles, the root is often Kidney and Liver Yin Deficiency. The tongue appears red with little or no coating, and the pulse feels thin and rapid. This pattern is the foundation for many preeclampsia cases, as insufficient Yin fails to anchor rising Yang.
When the Yin-deficient foundation allows Liver Yang to surge upward, the headache becomes severe and throbbing, accompanied by irritability, ringing in the ears, and a red face. The tongue is red with a yellow coating, and the pulse is wiry and forceful. This Liver Yang Rising pattern explains the high blood pressure and agitation that often appear suddenly.
If the main complaint is whole-body puffiness, abdominal bloating, poor appetite, and scanty urine, the problem lies in the Spleen’s inability to transform fluids. The tongue looks pale and swollen with teeth marks and a greasy white coating, while the pulse is soft or slippery. This Spleen Deficiency with Dampness pattern accounts for the pronounced edema and digestive sluggishness.
When the blood flow in the uterine vessels is obstructed, you may notice stabbing pains in the lower abdomen or chest, a dark or purplish complexion, and possibly restricted fetal growth. The tongue is dark red or purple with stasis spots, and the pulse feels choppy or wiry. This Blood Stagnation pattern directly affects placental perfusion and requires careful differentiation.
In more acute flare-ups, intense Liver Fire erupts, causing a dramatic spike in blood pressure, severe agitation, a bitter taste in the mouth, and bloodshot eyes. The tongue is red with a thick yellow coating, and the pulse is wiry and rapid. This Liver Fire Blazing pattern is a fiery escalation of Liver Yang and demands prompt attention to cool the Fire and calm the spirit.
When Dampness congeals into turbid Phlegm, you may feel chest oppression, a heavy sensation in the head, and cough up sticky sputum. The tongue coating is thick and greasy, and the pulse is slippery. This less common Phlegm pattern can complicate other imbalances and is often seen in those with a tendency toward fluid retention and sluggish digestion.
TCM Patterns for Preeclampsia
In TCM, the aim is to address the root cause, not just the symptom — it calls that root cause a “pattern.” The same preeclampsia can come from several different patterns, each treated differently. The quickest way to find yours is the quiz below.

Which signs match your experience?
It is normal to recognize pieces of yourself in several patterns. For example, Kidney and Liver Yin Deficiency often coexists with Liver Yang Rising, and Spleen Deficiency with Dampness can generate Phlegm. These patterns are not isolated boxes but interconnected stages of an imbalance that evolves during pregnancy.
To narrow things down, focus on the dominant feature. If the heaviness and swelling outweigh the dizziness, Spleen patterns may be central. If the headache and agitation are most troubling, look to Liver patterns. Notice what makes symptoms better or worse: rest and quiet tend to ease Yin deficiency, while salty or heavy foods can worsen Dampness.
Because tongue and pulse examination provides critical clues that are impossible to assess on your own, a professional TCM diagnosis is especially valuable in pregnancy. The practitioner will also consider your medical history and blood pressure readings to determine which pattern is primary and whether a combination needs to be addressed.
If you experience a sudden severe headache, visual changes, or a rapid rise in blood pressure, seek immediate medical care. Preeclampsia can progress quickly, and while TCM patterns offer insight into the underlying imbalance, they do not replace urgent obstetric monitoring.

Formulas traditionally used for preeclampsia
7 formulas across the patterns above. The right one depends on your pattern — start with the quiz if you're unsure which fits.
A classical formula that nourishes the Liver and Kidneys to support eye health and clear vision. It is used for blurred vision, dry eyes, sensitivity to light, excessive tearing in wind, dizziness, and ringing in the ears caused by Liver and Kidney Yin deficiency. Built on the famous Liu Wei Di Huang Wan (Six-Ingredient Rehmannia Pill) with the addition of goji berry and chrysanthemum flower for their vision-supporting properties.
A modern formula designed to calm an overactive Liver and settle internal Wind, used for headaches, dizziness, and insomnia caused by rising Liver Yang. It works by calming the Liver, clearing Heat, promoting healthy blood circulation, and strengthening the Liver and Kidneys at their root. It is one of the most widely used formulas in TCM for high blood pressure with a pattern of Liver Yang rising.
A foundational classical formula used to strengthen digestion and restore vitality. It gently tonifies the Spleen and Stomach to address fatigue, poor appetite, loose stools, and a pale complexion caused by Qi deficiency. All four herbs are mild and balanced, making this one of the gentlest and most widely used tonic formulas in Chinese medicine.
A classical four-herb formula used to address dizziness, heart palpitations, chest fullness, and shortness of breath caused by a weak digestive system failing to properly process fluids. It gently warms the body and helps move excess fluid accumulation, particularly when someone feels heavy, waterlogged, or dizzy upon standing.
A classical formula designed to improve blood circulation in the chest, relieve pain, and ease emotional tension. It is widely used for chronic chest pain, stubborn headaches, insomnia, and irritability caused by poor blood flow and stagnation in the upper body.
A powerful cooling formula used to address conditions caused by excess heat and dampness in the Liver and Gallbladder systems. It is commonly used for red, painful eyes, headaches, ear problems, irritability, urinary difficulties, and skin conditions like shingles, particularly when accompanied by a bitter taste in the mouth, dark urine, and a feeling of heat or inflammation along the sides of the body or in the genital area.
A foundational formula used to clear excess phlegm and dampness from the body, especially when they cause coughing with white phlegm, nausea, chest tightness, dizziness, or a heavy feeling in the limbs. It works by drying dampness, dissolving phlegm, and supporting healthy digestion. Named for its two key ingredients, Ban Xia and Chen Pi, which are most effective when aged.
Excess patterns like Liver Yang Rising or Liver Fire Blazing may show blood pressure and headache improvement within 2-4 weeks of herbs and acupuncture. Deficiency patterns such as Kidney and Liver Yin Deficiency often need 6-12 weeks to rebuild deep reserves. All treatment must be closely monitored with your obstetrician, and any sign of rapid worsening requires immediate medical attention.
Treatment principles
Across all patterns, TCM treatment of preeclampsia follows a single golden rule: protect the pregnancy while restoring balance. The strategy varies by pattern - nourishing Yin and subduing Yang for Liver patterns, strengthening the Spleen and draining Dampness for fluid overload, or gently invigorating Blood to remove stasis - but the underlying intent is always to calm the internal storm without harming the fetus.
Because pregnancy is a dynamic state, formulas and acupuncture protocols are adjusted frequently as symptoms shift. A woman may start with a formula for Liver Yang Rising and, as her blood pressure settles, transition to a Yin-nourishing formula to consolidate the gains. This phased, personalized approach is one of TCM's key strengths in managing a condition as complex and changeable as preeclampsia.
What to expect from treatment
Treatment typically involves weekly acupuncture sessions and daily herbal teas or powders. In the first two weeks, many women notice their swelling begins to soften, headaches become less intense, and sleep improves. Blood pressure readings may take longer to respond, and your practitioner will track them alongside your medical team. As your pattern shifts, your herbal formula will be modified - this is a normal sign of progress, not a setback.
It's essential to continue all prescribed conventional monitoring and to report any new or worsening symptoms immediately. TCM works best as a steady, supportive partner to your obstetric care, not as an emergency intervention.
General dietary guidance
Combining TCM with conventional treatment
TCM can be safely integrated with standard preeclampsia care, including antihypertensive medications and magnesium sulfate protocols. Herbs and acupuncture do not typically interact with these drugs, but because some herbs have diuretic or mild blood-thinning properties, your blood pressure and platelet levels should be monitored. Always inform both your TCM practitioner and your obstetrician of everything you are taking.
Crucially, TCM is not a substitute for urgent medical intervention. If your blood pressure spikes suddenly, you develop a severe headache, or you experience vision changes, seek emergency care immediately. TCM's role is to help stabilize the mother and potentially prolong pregnancy in the weeks before delivery, always under shared care.

Audience-specific guidance — open what applies to you
Preeclampsia typically resolves after delivery, but if hypertension or other symptoms persist, TCM treatment can continue during breastfeeding. Most herbs used for postpartum hypertension, such as Tian Ma, Gou Teng, and Du Zhong, are considered safe in lactation. However, very bitter-cold herbs like Long Dan Cao that could pass into breast milk and upset the infant’s digestion are generally avoided. Acupuncture remains an excellent option, as it carries no risk of drug transfer to the baby and can effectively regulate blood pressure and calm the Shen. Always inform your practitioner that you are breastfeeding so formulas can be adjusted accordingly.
Evidence & references
Evidence for TCM in preeclampsia is growing but remains of moderate quality. A 2025 Chinese clinical practice guideline provides standardized TCM diagnostic and treatment recommendations, reflecting expert consensus and some clinical studies. Several randomized controlled trials have examined Tian Ma Gou Teng Yin for gestational hypertension, showing reductions in blood pressure and proteinuria with a favorable safety profile, though many studies are small and conducted in single centers.
Acupuncture has also been studied as an adjunct therapy, with some trials suggesting it may help lower blood pressure and reduce anxiety in pregnant women with preeclampsia. However, high-quality, multicenter RCTs with rigorous blinding are still needed. The existing evidence supports TCM as a complementary approach alongside standard obstetric care, but patients should not rely on TCM alone for this serious condition.
Key clinical studies
This review summarizes the TCM patterns, herbal formulas, and acupuncture protocols commonly used for preeclampsia, and discusses pharmacological mechanisms such as anti-inflammatory, antioxidant, and vasodilatory effects of key herbs like Tian Ma and Gou Teng. It highlights the potential of integrated TCM-Western medicine approaches.

「子痫者，妊娠临产，忽然昏仆，不省人事，四肢抽搐，口噤，痰涎壅盛，目吊口歪，须臾自醒，醒后复发。」
"Eclampsia is when a woman near delivery suddenly collapses, loses consciousness, has convulsions of the limbs, lockjaw, profuse phlegm-drool, upward staring eyes and deviated mouth. She regains consciousness shortly but may relapse. This classical description of eclampsia, the severe progression of preeclampsia, underscores the urgency and the involvement of Liver Wind and Phlegm."

Frequently asked questions
Common questions about using Traditional Chinese Medicine for preeclampsia.
Yes, when prescribed by a qualified TCM practitioner who specializes in pregnancy care. Many herbs and acupuncture points are entirely safe and have been used for centuries to support maternal health. However, certain herbs that strongly move blood or drain downward are avoided because they could stimulate contractions. Always inform your practitioner that you are pregnant, and never self-prescribe herbs. Your TCM treatment should run alongside - not in place of - your regular prenatal checkups.
Acupuncture can be a helpful supportive tool, especially for patterns like Liver Yang Rising where calming the Liver and subduing Yang is key. Points such as Taichong (LR-3) and Fengchi (GB-20) are used to settle upward-rushing Qi and ease tension. While acupuncture alone is not a replacement for antihypertensive medication, many women find it reduces headache intensity, irritability, and overall stress, which can contribute to better blood pressure control. Always keep your medical team informed about any complementary treatments you are receiving.
Herbal formulas are chosen strictly according to your TCM pattern. For Liver Yang Rising, a classic formula like Tian Ma Gou Teng Yin uses herbs such as Gastrodia (Tian Ma) and Uncaria (Gou Teng) to calm the Liver and anchor Yang. For Spleen Deficiency with Dampness, formulas like Si Jun Zi Tang with added diuretic herbs like Fu Ling and Yi Yi Ren gently strengthen the Spleen and drain excess fluid. These herbs are considered safe when prescribed in pregnancy-appropriate doses by an experienced practitioner. Formulas that strongly invigorate blood, like Xue Fu Zhu Yu Tang, are used only with extreme caution and close monitoring, as they can affect placental blood flow. Your practitioner will select and adjust the formula with the baby's safety as the top priority.
Many women notice a reduction in swelling and headaches within the first two weeks. Blood pressure improvements can take a bit longer, often 2-4 weeks for excess patterns and 6-12 weeks for deeper deficiency patterns. Progress is gradual and cumulative, and it depends on how consistently you take your herbs and attend acupuncture sessions. Because preeclampsia can change rapidly, your TCM practitioner will work closely with you and your obstetrician to monitor your response and adjust the plan as needed.
Yes, TCM is often used alongside conventional medications. Herbs and acupuncture are generally complementary and do not interfere with drugs like labetalol or nifedipine. However, some herbs have mild diuretic or blood-moving effects, so your blood pressure should be tracked carefully. Always give your TCM practitioner a full list of your medications, and tell your obstetrician about any herbs or supplements you are taking. Never stop or adjust your prescribed medication without consulting your doctor.
TCM aims to treat the root imbalance that is driving your symptoms. For example, if your preeclampsia stems from Kidney and Liver Yin Deficiency, the herbs and acupuncture points are chosen to deeply nourish Yin and anchor Yang - not just to mask the headache. This means treatment continues even after blood pressure stabilizes, to rebuild your body's reserves and reduce the chance of recurrence. The goal is to create a healthier internal environment for the remainder of your pregnancy.
