Mastering Wind-Stroke: A Comprehensive Guide for NCCAOM Acupuncture Students
Hello everyone!!
Wind-stroke, or Zhong Feng, is one of the most critical conditions in Traditional Chinese Medicine (TCM), drawing a direct parallel to the medical understanding of stroke in Western medicine. For acupuncture students preparing for the NCCAOM board exams, a thorough understanding of wind-stroke is essential. This blog post will delve deep into the types, pathogenesis, symptoms, and treatment principles of wind-stroke, providing valuable insights that will not only aid in exam preparation but also enhance clinical practice.
First let's talk about Wind Stroke IN GENERAL
Wind-stroke, as described in TCM, involves a sudden onset of symptoms such as hemiplegia (paralysis on one side of the body), deviation of the eyes and mouth, and speech difficulties. The term "wind" signifies the sudden and unpredictable nature of the condition, much like how wind can strike without warning. This condition can be further categorized into two main types: attack on the zang-fu organs and attack on the meridians and collaterals.
Wind Stroke TYPES
TYPE 1: Attack on the Zang-Fu Organs
This type is further divided into two syndromes: the Closed (Tense) Syndrome and the Flaccid (Collapse) Syndrome.
Closed Syndrome (Tense Type): This is characterized by a sudden collapse, loss of consciousness, clenched jaws, and rigid limbs. The patient may exhibit a red face and wiry, forceful pulse. The tongue is usually red or purple with a thick, yellow, or greasy coating.
Flaccid Syndrome (Collapse Type): This type presents with a sudden collapse, loss of consciousness, cold limbs, weak breath, and incontinence. The patient's face is pale, the pulse is weak and thready, and the tongue appears pale with a thin white coating.
TYPE 2: Attack on the Meridians and Collaterals
This type of wind-stroke is marked by hemiplegia, numbness of the limbs, deviation of the mouth, and slurred speech. The pulse is typically wiry and slippery, and the tongue may appear purple with a thin white coating.
Pathogenesis!
The pathogenesis of wind-stroke in TCM is complex, involving several key factors:
Liver Wind: Internal Wind arises from Liver Yang Rising, Liver Fire, or Blood deficiency. The Liver's inability to anchor Yang leads to its upward disturbance, creating internal Wind.
Phlegm and Blood Stasis: The accumulation of Phlegm and Blood stasis obstructs the meridians and collaterals, leading to wind-stroke. Phlegm often combines with Wind, exacerbating the condition.
Qi and Blood Deficiency: Chronic Qi and Blood deficiencies weaken the body's defensive mechanisms, making it susceptible to Wind invasion. This deficiency can be a result of prolonged illness, poor diet, or chronic stress.
Key Symptoms of Wind-Stroke
Recognizing the symptoms of wind-stroke is crucial for accurate diagnosis and timely intervention. Key symptoms include:
- Sudden onset of hemiplegia
- Deviation of the eyes and mouth
- Slurred speech or aphasia
- Sudden loss of consciousness in severe cases
- Rigid or flaccid limbs depending on the type of wind-stroke
- Incontinence and cold limbs in flaccid syndrome
Treatment Principles for Wind-Stroke
The treatment of wind-stroke in TCM involves a combination of acupuncture, herbal medicine, and lifestyle modifications. Here are the main treatment principles based on the type of wind-stroke:
Expelling External Wind
For cases where Wind invades the meridians and collaterals, the treatment focuses on expelling Wind and restoring the function of the channels. Acupuncture points commonly used include:
- DU-26 (Shuigou): Revives consciousness and benefits the brain.
- ST-40 (Fenglong): Resolves Phlegm and opens the orifices.
- LI-4 (Hegu): Expels Wind and releases the exterior.
- LI-11 (Quchi): Clears Heat and cools the Blood.
- GB-34 (Yanglingquan): Benefits the sinews and joints, addressing muscle spasm and rigidity.
2. Calming Internal Wind
For internal Wind conditions, the focus is on calming the Liver and extinguishing Wind. Acupuncture points and herbal formulas are chosen to pacify the Liver and anchor Yang. Key acupuncture points include:
- LV-3 (Taichong): Calms the Liver and extinguishes Wind.
- GB-20 (Fengchi): Expels external Wind and clears the head.
- DU-20 (Baihui): Pacifies internal Wind and lifts the Qi.
- PC-6 (Neiguan): Calms the Heart and regulates the Liver.
3. Resolving Phlegm and Blood Stasis
Using acupuncture points and herbal formulas to dissolve Phlegm and invigorate Blood circulation is essential in treating wind-stroke. Important points include:
- SP-9 (Yinlingquan): Resolves Dampness and benefits the lower jiao.
- SP-6 (Sanyinjiao): Tonifies the Spleen and resolves Dampness.
- BL-17 (Geshu): Invigorates Blood and dispels stasis.
- ST-36 (Zusanli): Tonifies Qi and Blood, harmonizes the Stomach, and resolves Dampness.
4. Tonifying Qi and Blood**
Strengthening the body's Qi and Blood to aid recovery and prevent recurrence is crucial. Acupuncture points and herbal therapies that tonify Qi and Blood include:

Lifestyle Modifications for Prevention and Recovery
In addition to acupuncture and herbal treatments, lifestyle modifications play a vital role in preventing and recovering from wind-stroke:
- Diet: A balanced diet rich in whole grains, vegetables, and lean proteins supports overall health. Avoiding excessive alcohol, caffeine, and greasy foods can prevent Phlegm accumulation.
- Exercise: Regular physical activity promotes Qi and Blood circulation, reducing the risk of stagnation and stasis.
- Stress Management: Techniques such as meditation, Tai Chi, and Qi Gong help manage stress and maintain emotional balance, preventing Liver Qi stagnation.
- Regular Check-Ups: Monitoring blood pressure and cholesterol levels can help identify risk factors early, allowing for timely intervention.
