Basilar artery insufficiency isn't a single condition in TCM - it's a family of six distinct patterns, each with its own cause and characteristic dizziness. From Qi and Blood Deficiency that leaves the brain undernourished to Liver Yang Rising that sends Heat surging upward, the type of vertigo you experience points to the underlying imbalance. This page explores how TCM restores blood flow to the brain by addressing the root cause, not just masking the symptoms.
Basilar artery insufficiency refers to reduced blood flow in the vertebrobasilar system, which supplies the brainstem, cerebellum, and occipital lobes. This can lead to symptoms like vertigo, dizziness, visual disturbances, tinnitus, and in severe cases, stroke. Diagnosis typically involves imaging such as MRI, CT angiography, or ultrasound to assess blood flow and vessel structure.
Conventional treatments
Conventional management often includes antiplatelet medications like aspirin to prevent clots, blood pressure control, and lifestyle modifications such as diet and exercise. In some cases, surgery or stenting may be recommended to open narrowed arteries.
Where conventional treatment falls short
While these treatments reduce stroke risk, they don't always address the underlying imbalances that contribute to poor circulation, such as chronic stress, dietary habits, or constitutional weaknesses. The conventional approach treats all cases similarly, without differentiating between patterns of dizziness - which is precisely what TCM does.
How TCM understands basilar artery insufficiency
TCM understands basilar artery insufficiency primarily as a disorder of brain nourishment. The brain relies on a steady supply of Qi and Blood, produced by the Spleen from food and stored by the Liver and Kidneys. When these organs are weakened by overwork, poor diet, or aging, the brain becomes undernourished, leading to dizziness and other symptoms. The quality of the dizziness - whether it's a floating emptiness, a heavy cloudiness, or a sudden spinning - reveals which organ system is most affected.
The Spleen transforms food into Qi and Blood. If digestion is weak or the body is exhausted, Qi and Blood become deficient, causing a floating, empty-headed dizziness that worsens with fatigue. This is the Qi and Blood Deficiency pattern. Conversely, when the Spleen fails to manage fluids, Dampness accumulates into Phlegm, which can obstruct the channels to the brain, resulting in a heavy, clouded sensation - the Phlegm in Channels pattern.
The Kidneys store essence that produces marrow for the brain, while the Liver ensures smooth Qi flow. When Kidney and Liver Yin are depleted from chronic stress or aging, the brain loses nourishment and dizziness with tinnitus and dry eyes occurs. Emotional stress can also cause Liver Yang to rise, bringing Heat to the head and causing sudden, severe vertigo with irritability - the Liver Yang Rising pattern. Blood Stagnation from sluggish circulation leads to fixed, stabbing dizziness, and in rare cases, Wind-Phlegm can cause sudden, severe spinning vertigo with phlegm production.
「诸风掉眩，皆属于肝。」
"All wind with tremor and vertigo pertains to the Liver. This foundational statement links dizziness and spinning sensations to Liver dysfunction, particularly Liver Wind and Liver Yang rising, which remain core patterns in basilar artery insufficiency."
How a TCM practitioner diagnoses basilar artery insufficiency
Inside the consultation
A practitioner begins by asking what the dizziness actually feels like and what makes it better or worse. With basilar artery insufficiency, the quality of the vertigo - whether it is a spinning sensation, a heavy cloudiness, or a feeling of floating - is the first clue that points toward one pattern rather than another.
If the dizziness is accompanied by marked fatigue, pale complexion, and a sensation of emptiness in the head, the picture suggests Qi and Blood Deficiency. The brain is undernourished, so symptoms worsen with exertion and improve with rest. The tongue is pale with a thin white coat, and the pulse is thin and weak, confirming the need to build up the body’s resources.
When the head feels heavy, as if wrapped in a wet cloth, and the vertigo is accompanied by chest tightness, nausea, and a greasy tongue coating, Phlegm in the Channels is likely the culprit. The pulse will feel slippery, reflecting the turbid dampness clouding the clear orifices. This pattern is common in people with a sluggish digestion and a tendency toward weight gain.
In older adults, a pattern of Kidney and Liver Yin Deficiency often underlies the problem. The dizziness is less heavy and more of a light-headed, floating sensation, paired with tinnitus, blurred vision, and soreness in the lower back and knees. The tongue is red with little coating, and the pulse is thin and rapid. If the dizziness suddenly intensifies with irritability, a red face, and a pounding headache, the picture has shifted to Liver Yang Rising, an acute flare that requires immediate attention.
When the dizziness feels fixed and stabbing, with dark spots on the tongue and a choppy pulse, Blood Stagnation is likely present, often as a complication of long-standing deficiency or Phlegm. Rarely, a sudden storm of Wind-Phlegm causes severe spinning vertigo with copious phlegm and neurological signs like numbness or slurred speech.
TCM Patterns for Basilar Artery Insufficiency
In TCM, the aim is to address the root cause, not just the symptom — it calls that root cause a “pattern.” The same basilar artery 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 very common to see a bit of yourself in more than one pattern. For example, long-standing Qi and Blood Deficiency can eventually drain the Kidney and Liver Yin, creating a mixed picture of fatigue and dry, floating dizziness. These patterns overlap because they all share the same root: the brain is not receiving the nourishment and clear flow it needs.
Similarly, Phlegm in the Channels and the rarer Wind-Phlegm pattern both involve a sensation of heaviness and cloudiness, but Wind-Phlegm tends to cause more sudden, shifting neurological symptoms like numbness or slurred speech. If your symptoms come on abruptly or feel different from your usual pattern, that is a signal to seek professional care without delay.
Because the tongue and pulse provide critical information that you cannot assess on your own, a professional diagnosis is invaluable, especially when patterns are mixed. And because some patterns - like Liver Yang Rising, Blood Stagnation, or Wind-Phlegm - can indicate a higher risk of stroke, any sudden, severe, or worsening vertigo should be evaluated by a practitioner promptly rather than self-treated.

Formulas traditionally used for basilar artery insufficiency
6 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 simultaneously replenishes both Qi and Blood, created by combining two famous prescriptions: Si Jun Zi Tang (for Qi) and Si Wu Tang (for Blood). It is commonly used for people who feel chronically tired, look pale or sallow, have a poor appetite, experience dizziness or heart palpitations, and feel generally run down due to dual deficiency of Qi and Blood.
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 relieve dizziness, vertigo, and headache caused by a buildup of internal dampness and phlegm combined with internal Wind. It works by dissolving phlegm, calming the Liver, and strengthening the digestive system to stop new phlegm from forming. It is especially well suited for people who experience spinning dizziness with nausea, a heavy head, and a sensation of fogginess or fullness in the chest.
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 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.
Excess patterns like Liver Yang Rising or Phlegm obstruction often respond within 2-4 weeks of treatment. Deficiency patterns, such as Qi and Blood Deficiency or Kidney Yin Deficiency, may require 3-6 months to rebuild the body's reserves. Consistent weekly acupuncture and daily herbs are key.
Treatment principles
Treatment focuses on restoring blood flow to the brain by addressing the underlying pattern. For deficiency, we nourish Qi and Blood or Yin; for excess, we clear Phlegm, subdue Yang, or invigorate Blood. Acupuncture points like Baihui DU-20 and Fengchi GB-20 are universally used to calm the mind and improve circulation, while herbs are tailored to the specific pattern - such as Ba Zhen Tang for deficiency or Tian Ma Gou Teng Yin for Liver Yang Rising.
What to expect from treatment
Most patients have weekly acupuncture sessions and take daily herbal formulas. You may notice reduced dizziness within 2-4 weeks, but full benefits take longer. Between sessions, dietary and lifestyle changes support healing. Progress is monitored through symptom changes and tongue/pulse assessment.
General dietary guidance
Avoid heavy, greasy, or cold foods that create Dampness and Phlegm. Favor warm, cooked meals like soups and stews to support Spleen function. Include foods like ginger tea to resolve Phlegm, and nourishing ingredients like goji berries for Yin deficiency. Small, frequent meals are better than large ones.
Combining TCM with conventional treatment
TCM can be safely combined with conventional treatments like antiplatelet drugs. However, herbs that move Blood, such as Dang Gui or Chuan Xiong, may interact with anticoagulants. Always disclose all medications to your TCM practitioner and consult your doctor before making changes. If symptoms worsen, seek medical attention promptly.

Safety & special considerations
-
Sudden, severe vertigo unlike any previous episode — May indicate a stroke or transient ischemic attack. Seek emergency care immediately.
-
Vision loss or double vision — Could be a sign of brainstem involvement requiring urgent evaluation.
-
Slurred speech or difficulty swallowing — These are potential stroke symptoms and need immediate medical attention.
-
Numbness or weakness on one side of the body — Possible stroke symptom; do not wait to see if it resolves.
-
Loss of consciousness — Seek emergency care right away, as this could indicate a serious event.
Audience-specific guidance — open what applies to you
In older adults, basilar artery insufficiency most often stems from Kidney and Liver Yin Deficiency, Phlegm obstruction, or Blood Stasis-patterns driven by decades of wear and tear. Treatment must be gentle: herb dosages are typically reduced to two-thirds of the adult standard, and formulas like Qi Ju Di Huang Wan or Ban Xia Bai Zhu Tian Ma Tang are favoured for their mild, nourishing action. Acupuncture is especially safe and well-tolerated, with points such as Baihui DU-20, Fengchi GB-20, and Taixi KI-3 used to support brain circulation without overstimulating a frail system.
Polypharmacy is a real concern, so practitioners must check for interactions between herbal formulas and blood thinners, antihypertensives, or antiplatelet drugs. Because deficiency patterns recover slowly, elderly patients should expect a longer treatment timeline-often several months of consistent care-and should be monitored for any sudden worsening that could signal a transient ischaemic attack.
Evidence & references
Acupuncture and Chinese herbal medicine for vertebrobasilar insufficiency have been studied in a modest number of Chinese-language randomised controlled trials. A 2015 systematic review of these trials concluded that TCM interventions, particularly herbal formulas and acupuncture, can improve blood flow velocity in the basilar and vertebral arteries and reduce dizziness severity. However, most included studies were small and of variable methodological quality, so the findings must be interpreted cautiously.
Western-language evidence remains sparse. While individual herbs like Tian Ma (Gastrodia) and Dan Shen (Salvia) show vasodilatory and neuroprotective effects in laboratory studies, large, well-designed clinical trials are lacking. The current evidence suggests TCM is a promising adjunctive therapy, especially for patients who cannot tolerate or do not fully respond to conventional vasodilators, but more rigorous research is needed.
Key clinical studies
This systematic review evaluated RCTs of Chinese herbal medicine and acupuncture for vertebrobasilar insufficiency. The pooled analysis suggested that TCM interventions significantly improved clinical symptoms and transcranial Doppler blood flow parameters compared to conventional treatment alone, though the quality of the included studies was generally low.

Chapter on Vertigo
「无虚不作眩。」
"There is no vertigo without deficiency. Zhang Jingyue argued that underlying deficiency-whether of Qi, Blood, Yin, or Essence-is the root of most chronic dizziness, mirroring the Qi and Blood Deficiency and Kidney-Liver Yin Deficiency patterns that dominate basilar insufficiency in older patients."
