Also known as: Brain Vascular Insufficiency, Cerebrovascular Insufficiency
The heavy, foggy dizziness of Phlegm, the throbbing stress-triggered headache of Liver Yang Rising, and the washed-out fatigue of Qi and Blood Deficiency are three different patterns - and most patients see clearer thinking and less dizziness within 6-12 weeks of pattern-matched TCM treatment.

Cerebral vascular insufficiency isn't a single condition in TCM - it's a family of six distinct patterns, each with its own root cause and treatment. While conventional medicine focuses on narrowed or damaged vessels, TCM looks deeper at why the brain isn't receiving the steady nourishment of Qi and Blood it needs.
That could mean Liver Yang surging upward, Phlegm clogging the channels, or deep Yin and Blood deficiency leaving the brain under-supplied. The right herbs and acupuncture points depend entirely on which pattern is driving your symptoms.
Cerebral vascular insufficiency refers to a chronic reduction in blood flow to the brain, often caused by atherosclerosis, small vessel disease, or other vascular narrowing. It can produce a range of symptoms including dizziness, brain fog, poor concentration, headaches, and in more advanced cases, transient ischemic attacks (TIAs). Diagnosis is typically made through imaging such as MRI, CT angiography, or Doppler ultrasound to assess blood flow and vessel health.
Conventional treatments
Standard treatment aims to manage underlying risk factors and prevent stroke. This often includes antiplatelet medications like aspirin or clopidogrel, cholesterol-lowering statins, and strict blood pressure control. In some cases, surgical procedures such as carotid endarterectomy may be recommended. Lifestyle changes - quitting smoking, improving diet, and increasing exercise - are also emphasized to slow disease progression.
Where conventional treatment falls short
These treatments focus primarily on preventing major events like stroke, but they often leave patients still struggling with daily symptoms of dizziness, mental cloudiness, and fatigue. Medications can cause side effects such as bleeding risk or muscle pain, and they don't address the underlying constitutional imbalances that, from a TCM perspective, contribute to sluggish cerebral circulation. TCM offers a complementary approach that targets the specific pattern behind each person's symptoms, aiming to restore clear-headedness and vitality rather than just managing vascular risk factors.
How TCM understands cerebral vascular insufficiency
In TCM, the brain is seen as the "sea of marrow," nourished by the upward flow of clear Qi and Blood. This nourishment depends on the smooth functioning of several organ systems. The Liver stores Blood and ensures the free flow of Qi; if Liver Qi stagnates or Liver Yang flares upward, the head can feel throbbing, dizzy, and pressured. The Spleen transforms food into Qi and Blood; when it's weak, dampness and Phlegm can form, rising to cloud the brain and causing a heavy, foggy sensation.
The Kidneys store essence and produce marrow, which fills the brain. As we age or after prolonged overwork, Kidney Yin and Essence can become depleted, leaving the brain undernourished and overheated - this produces dizziness with tinnitus, poor memory, and a feeling of emptiness. Blood Stagnation is another common mechanism: when circulation is sluggish due to chronic Qi stagnation or deficiency, the brain's vessels become obstructed, leading to fixed, stabbing headaches and mental dullness.
Because so many different organ imbalances can reduce cerebral blood flow, the same Western diagnosis can arise from opposite TCM patterns. One person's dizziness may flare with stress and anger (Liver Yang Rising), while another's worsens with fatigue and poor appetite (Qi and Blood Deficiency). This is why TCM doesn't treat "cerebral vascular insufficiency" as one disease - it identifies the exact pattern and tailors the treatment accordingly, using herbs, acupuncture, and dietary changes to correct the root imbalance and restore healthy brain circulation.

How a TCM practitioner diagnoses cerebral vascular insufficiency
Inside the consultation
A TCM practitioner starts by asking about the sensation itself: is the dizziness a spinning vertigo, a floating lightness, or a heavy, foggy feeling? What makes it flare up or settle down-stress, fatigue, certain foods? The tongue and pulse then confirm which pattern is driving the brain's insufficient blood supply.
If dizziness comes with a throbbing headache, a flushed face, and a short temper, and the pulse feels tight like a guitar string (wiry, 脉弦), Liver Yang Rising is likely. Stress is a major trigger, and the tongue may appear red with a yellow coating.
When the head feels heavy as if wrapped in a cloth, accompanied by chest tightness and nausea, a greasy tongue coating and a slippery pulse (脉滑) point to Phlegm obstructing the collaterals. This pattern often follows a diet rich in fatty, sweet, or damp-producing foods.
A fixed, stabbing headache that worsens at night, together with a dark purple tongue and a choppy pulse, signals Blood Stagnation in the brain's vessels. This typically develops in chronic cases where circulation has been sluggish for a long time.
Dizziness that intensifies with even gentle activity, combined with deep fatigue and a pale, washed-out complexion, suggests Qi and Blood Deficiency. The pulse is weak and thin, and the tongue looks pale-signs that the brain is simply not receiving enough nourishment.
When dizziness is paired with ringing in the ears, a sensation of heat in the palms and soles, and a red tongue with very little coating, the picture is Liver Yang Rising with Blood and Yin Deficiency. The pulse is thin and rapid, reflecting yin that is too depleted to anchor the rising yang.
In older adults, a gradual onset of dizziness with dry eyes, night sweats, and a red tongue with scant coating often reveals Kidney and Liver Yin Deficiency. This deep, underlying depletion is a common root that predisposes the brain's vessels to insufficiency.
TCM Patterns for Cerebral Vascular Insufficiency
In TCM, the aim is to address the root cause, not just the symptom — it calls that root cause a “pattern.” The same cerebral vascular insufficiency 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 see bits of yourself in more than one pattern. Chronic cerebral vascular insufficiency often blends patterns-you might have Qi deficiency with some blood stasis, or Liver Yang rising built on a foundation of yin deficiency. The goal is to identify which pattern is dominant right now.
Notice what makes your symptoms better or worse. If rest and a nourishing meal bring relief, Qi and Blood Deficiency may be central. If a stressful argument triggers a pounding headache, Liver Yang Rising is likely at the forefront. A tongue coating that remains greasy after brushing hints that phlegm is playing a role.
Because these patterns overlap and the tongue and pulse are essential to a clear diagnosis, seeing a professional is wise. If dizziness appears suddenly, is severe, or comes with one‑sided weakness or slurred speech, seek emergency medical care immediately rather than trying to self‑treat.
A trained TCM practitioner can pinpoint the exact mix of patterns and design a plan-often combining herbs and acupuncture-to restore balance and improve cerebral blood flow. Gentle exercise and dietary adjustments can support recovery, but the root pattern needs professional guidance to be safely addressed.

Four ways to address cerebral vascular insufficiency in TCM — explore each, or take the quiz to see what fits you first.
Formulas traditionally used for cerebral vascular insufficiency
5 formulas across the patterns above. The right one depends on your pattern — start with the quiz if you're unsure which fits.
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 classical formula designed to improve blood circulation in the head and face, used for stubborn headaches, hair loss, hearing difficulties, skin discolorations, and other problems caused by stagnant blood obstructing the sensory organs. It works by powerfully moving blood and opening the body's orifices (eyes, ears, nose, mouth) in the upper body.
A classical formula that strengthens the Spleen and nourishes the Heart to address fatigue, poor appetite, insomnia, forgetfulness, palpitations, and anxiety caused by weakness of both the Heart and Spleen. It is also widely used for bleeding disorders such as heavy or prolonged menstrual periods, easy bruising, or blood in the stool that result from the Spleen being too weak to keep blood in its proper channels.
A classical formula designed to calm the Liver and stop internally generated Wind, used for conditions related to high blood pressure, dizziness, headache, and stroke risk caused by an overactive Liver and depleted Kidney Yin. It works by anchoring rising Qi and Blood back downward, calming the Liver, nourishing Yin, and preventing the chaotic upward rush that can lead to serious neurological symptoms.
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.
Excess patterns like Liver Yang Rising or Phlegm obstruction often respond within 4-8 weeks of weekly acupuncture and daily herbs. Blood Stagnation patterns may take 8-12 weeks to show significant improvement. Deficiency patterns - especially those involving Kidney Yin or Qi and Blood - require a longer commitment, typically 3-6 months, as the body's reserves are rebuilt. Most patients notice some improvement in mental clarity and energy within the first month.
Treatment principles
Treatment always aims to restore the smooth, nourishing upward flow of Qi and Blood to the brain, but the method depends entirely on the pattern. For Liver Yang Rising, the focus is on calming the Liver and anchoring Yang with herbs like Tian Ma and Gou Teng and points like Taichong LR-3.
For Phlegm obstruction, the priority is to dissolve Phlegm and open the channels using points like Fenglong ST-40 and herbs like Tian Ma and Dan Nan Xing. Blood Stagnation calls for invigorating formulas like Tong Qiao Huo Xue Tang, while deficiency patterns are treated with nourishing formulas like Gui Pi Tang or Qi Ju Di Huang Wan.
Acupuncture points on the head - Baihui DU-20, Fengchi GB-20 - are used across many patterns to directly improve local circulation. The treatment plan is never one-size-fits-all; your practitioner will adjust the formula and point selection as your pattern shifts over time.
What to expect from treatment
You'll likely start with weekly acupuncture sessions and a daily herbal formula. Many patients notice a subtle lifting of brain fog and a reduction in dizziness within the first 2-4 weeks. More significant improvements - steadier energy, clearer thinking, fewer headaches - typically build over 6-12 weeks. Deficiency patterns require patience; the body needs time to rebuild Qi, Blood, and Yin, so progress may be gradual but steady. Your practitioner will check your tongue and pulse at each visit to track changes and refine your treatment.
General dietary guidance
To support healthy cerebral circulation, avoid foods that create Phlegm and dampness - greasy, fried, and heavily sweetened items, as well as excessive dairy. If your pattern involves heat or rising Yang, also limit alcohol, coffee, and spicy foods.
Favour warm, cooked meals like soups and congees that are easy to digest. Incorporate blood-nourishing foods such as dark leafy greens, beets, lean meats, and goji berries. Staying well-hydrated with warm water or herbal teas helps keep the vessels supple.
Combining TCM with conventional treatment
TCM works well alongside conventional care for cerebral vascular insufficiency. Acupuncture is non-pharmacological and does not interfere with medications. Herbal formulas must be carefully coordinated with any blood-thinning drugs (warfarin, aspirin, clopidogrel) because herbs like Dang Gui, Chuan Xiong, and Hong Hua can enhance anticoagulant effects. Always bring a complete list of your medications to your TCM consultation, and inform your prescribing doctor that you're starting TCM treatment. Never stop or adjust your conventional medications without medical supervision.

Audience-specific guidance — open what applies to you
During pregnancy, the body's Blood and Yin are directed to nourish the fetus, making Qi and Blood Deficiency and Kidney Yin Deficiency patterns more prominent. Dizziness from cerebral vascular insufficiency may intensify, especially in the second and third trimesters. Formulas like Gui Pi Tang are generally considered safe, while Tian Ma Gou Teng Yin can be used cautiously under professional guidance, as its herbs like Tian Ma and Gou Teng are not strongly contraindicated.
However, formulas that strongly move blood, such as Tong Qiao Huo Xue Tang with Hong Hua, must be avoided due to the risk of miscarriage. Acupuncture is a safe and effective alternative, with points like Zusanli ST-36 and Sanyinjiao SP-6 used carefully (Sanyinjiao is often avoided in early pregnancy by some practitioners). Always consult a TCM practitioner experienced in prenatal care.
Most TCM herbs are safe during breastfeeding when prescribed appropriately, but bitter-cold herbs that can cause infant diarrhoea should be used with caution. For Liver Yang Rising, Tian Ma Gou Teng Yin is generally well-tolerated. Qi and Blood Deficiency formulas like Gui Pi Tang are nourishing and can even support milk production. Acupuncture is entirely safe and can be used freely to improve cerebral blood flow without affecting breast milk. As always, any herbal treatment should be monitored by a qualified TCM practitioner to ensure the baby's well-being.
Cerebral vascular insufficiency is most common in the elderly, where Kidney and Liver Yin Deficiency, Qi and Blood Deficiency, and Blood Stagnation are the dominant patterns. Treatment must be gentle and sustained, as the body's reserves are low.
Herbal dosages are typically reduced to two-thirds of the adult dose, and formulas like Qi Ju Di Huang Wan or Gui Pi Tang are preferred over strong blood-moving decoctions that might deplete Qi further. Acupuncture is well-tolerated and can be a cornerstone of therapy.
Polypharmacy is a significant concern, as many elderly patients take blood thinners or antihypertensive medications. Herbs like Dan Shen and Chuan Xiong have mild anticoagulant effects and should be used only with close monitoring.
The treatment timeline is longer - expect several months of consistent therapy to see meaningful improvement in cerebral blood flow and symptom relief. Lifestyle adjustments, including gentle exercise like Tai Chi and a diet rich in nourishing foods, are essential complements.
Evidence & references
Clinical research on TCM for cerebral vascular insufficiency is growing but remains modest in scale. Several randomized controlled trials have shown that acupuncture can increase cerebral blood flow velocity and improve symptoms of dizziness and cognitive fog. Herbal formulas such as Tian Ma Gou Teng Yin and Bu Yang Huan Wu Tang have demonstrated benefits in reducing blood viscosity and enhancing microcirculation in patients with chronic cerebral hypoperfusion. However, many studies are small and lack rigorous blinding, so the evidence, while promising, is not yet definitive.
A 2022 systematic review published in Frontiers in Neuroscience examined Buyang Huanwu Decoction for cerebral small vessel disease and found consistent improvements in cognitive function and cerebral hemodynamics across multiple trials. Expert consensus guidelines from the Chinese Association of Integrative Medicine also endorse pattern-based herbal and acupuncture protocols. Larger, well-designed international trials are needed to confirm these findings for a global audience.

Frequently asked questions
Common questions about using Traditional Chinese Medicine for cerebral vascular insufficiency.
Yes. Acupuncture has been shown to increase cerebral blood flow by dilating blood vessels and improving microcirculation. Herbal formulas are designed to address the specific pattern causing sluggish flow - whether it's by dissolving Phlegm, invigorating Blood, or nourishing Qi and Yin. Many patients report feeling clearer-headed and less dizzy after several weeks of consistent treatment.
For excess patterns like Liver Yang Rising or Phlegm obstruction, dizziness often begins to lift within 2-4 weeks of starting herbs and acupuncture. If your dizziness is due to deeper deficiency (Qi and Blood or Kidney Yin), it may take 6-8 weeks to notice a steady improvement, and full resolution can take several months. Your practitioner will track your progress and adjust the formula as needed.
Absolutely - never stop prescribed medications without consulting your doctor. TCM treatment can safely complement most conventional therapies. However, some herbs like Dang Gui and Chuan Xiong have mild blood-thinning effects, so your TCM practitioner must know all your medications to avoid interactions. Always inform both your doctor and your TCM practitioner about everything you're taking.
Acupuncture is generally safe after a TIA, and it's often used to support recovery and prevent recurrence by improving circulation and calming the nervous system. However, you should always tell your acupuncturist about your full medical history, including any TIAs or strokes. In the early days after a TIA, treatment may be gentle and focused on distal points rather than the head.
Diet plays a supporting role. Generally, you'll be advised to avoid greasy, fried, and sugary foods that create Phlegm and dampness. If your pattern involves Liver Yang Rising, you'll also want to limit alcohol, caffeine, and spicy foods. Nourishing, warm, easily digested meals - soups, congees, steamed vegetables - help build Qi and Blood. Your practitioner will give you specific guidance based on your pattern.
Most patients start with one or two sessions per week for 6-12 weeks. After that, the frequency often reduces to once every two weeks or monthly for maintenance. The total number depends on your pattern and how long you've had symptoms - recent-onset excess patterns may need fewer sessions, while chronic deficiency patterns benefit from longer, consistent care.
