Consulting medical texts since the *Neijing* (Classic of Internal Medicine), it is generally stated that this is caused by external wind pathogen invasion. However, there are differences between northern and southern regions, and one cannot generalize based on a single approach. Only Liu Shouzhen's proposition that "improper lifestyle management leads to water failing to control fire" is highly accurate. Speaking from today's perspective, in the northwest regions, there are indeed cases of true wind stroke, but they are extremely rare. People in the southeast are mostly affected by damp earth generating phlegm, phlegm generating heat, and heat generating wind. Where pathogens gather, qi must be deficient. Wind pathogens injure the body, predominantly affecting the Lung organ. Xu Xueshi stated that "Qi Zhong" (Qi Strike) is also caused by injury from the Seven Emotions, with a pulse that is subtle and rapid, or floating and tight, slow and delayed. A pulse that is slow and floating indicates a treatable condition, whereas a pulse that is large, rapid, and extreme indicates death. If it is indeed an external wind strike, then it follows Dong Yuan's principles of striking the blood vessels, fu organs, or zang organs. The symptom of limbs being unable to lift is similar to Wei Syndrome (Flaccidity Syndrome), and careful differentiation is required. Treating Feng (Wind) diseases and Wei (Flaccidity) diseases together in the *Ju Fang* (Formulas of the Bureau) is a major error, which has been elaborated upon extensively. Hezi used the three methods (sweating, vomiting, purging); these can be used if it is truly a sudden wind strike with abundant phlegm and excess heat, otherwise, they should not be used.

Wind is the beginning of all diseases; it moves swiftly and changes frequently. "Moving" implies motion. Wind is fundamentally heat; when heat prevails, wind moves. One should use stillness to overcome its dryness, and nourishing blood is the method. Treatment requires using few acrid/dispersing agents and should also avoid purgatives. Excessive sweating depletes Wei Qi (Defensive Qi), and excessive purging damages Ying Blood (Nutritive Blood). When treating disease in the meridians, although there are taboos against sweating and purging, there is a distinction between striking the zang and fu organs. Striking the fu organs warrants sweating. Striking the zang organs warrants purging. Although this aligns with sweating and purging, it must not be excessive. Excessive sweating leads to loss of Yang, and excessive purging leads to loss of Yin. Loss of Yang damages Qi, and loss of Yin damages the physical form. Initially, if exterior and interior are disharmonious, sweating and purging are needed. Once exterior and interior are harmonized, treatment should focus on the meridians. In cases of striking the fu organs, five colors manifest, accompanied by exterior symptoms such as floating pulse, aversion to wind, aversion to cold, stiffness, spasms, and numbness. Whether occurring on the front, side, or after onset, it is called striking the fu organs, and treatment is relatively easy. In cases of striking the zang organs, there is flaccidity of the lips and mouth, inability to move the tongue resulting in aphonia, anosmia, deafness, and blurred vision, constipation of stool and urine, or eyes closed with fixed gaze, head shaking, open mouth, relaxed hands, urinary incontinence, rattling sputum like sawing wood, and snoring. This is called striking the zang organs. Striking the zang organs is often untreatable. Disharmony of the six fu organs leads to stagnation and accumulation forming abscesses. Disharmony of the five zang organs leads to obstruction of the nine orifices. Without these symptoms, the disease remains in the meridians. Once the initial syndrome is established, it is appropriate to nourish with major tonics, adjusting yin and yang according to the seasons, calming the zang organs, and harmonizing Ying and Wei Qi. Few cases will fail to heal. For wind striking the fu organs, first use Modified Chucming Decoction to release the exterior according to the syndrome. If combined with striking the zang organs, bowel movements are often constipated, so Sanhua Decoction should be used to unblock stagnation. Once the initial syndrome is stabilized without other changes, treat with major tonics to harmonize. Generally, striking the fu organs affects the four limbs, while striking the zang organs obstructs the nine orifices. Striking the fu organs often includes symptoms of striking the zang organs. As for tongue stiffness and aphonia, long-term use of major tonics will naturally lead to recovery.

Furthermore, due to Qi Zhong, the symptoms resemble wind stroke, but wind strike involves much phlegm-saliva, whereas Qi Zhong has no saliva in the mouth. The treatment method prioritizes regulating qi. The classics state that treating wind involves regulating qi; when qi flows smoothly, phlegm dissipates. Gradually managing the wind can yield results. There are also cases of wind stroke where speech is unchanged and consciousness is intact, with the disease located in the fenli (interstitial spaces); only warming the Liver and inducing slight sweating allows for recovery.

In general, the pulse in wind stroke is often deep and hidden. The general rule is that floating and slow pulses are auspicious, while rapid and full pulses are ominous. First, administer Suhexiang Wan (Styrax Pill) mixed with sesame oil, or Sanjiang Decoction (Three Ginger Decoction), or mix with warm water. If the jaw is locked, pry it open and administer. Upon slight revival, administer Bawei Shunqi Powder (Eight-Ingredient Qi-Regulating Powder). If phlegm is abundant, only Shengfeng Daotan Decoction (Phlegm-Resolving and Wind-Expelling Decoction) should be taken. If the patient lies unconscious and unresponsive with a locked jaw, urgently blow raw Pinellia Rhizome powder into the nose, or use Asarum and Gleditsia Sinensis powder blown into the nose. Sneezing indicates revival; lack of sneezing indicates untreatability. In obese individuals suffering from wind strike, qi is abundant externally but deficient internally. The Lung is the pathway for qi entry and exit; obesity implies urgent qi, and urgent qi implies excess Lung Pathogen. Metal overcomes Wood; the Gallbladder is the Fu organ of the Liver, hence phlegm-saliva is abundant. Therefore, treatment must prioritize regulating qi. After wind strike, if qi is not smooth and phlegm is not cleared, conditioning agents should consist of Huoxiang Zhengqi Decoction (Agastache Decoction for Rectifying the Qi) and Xingxiang San (Star Anise and Atractylodes Powder) decocted together. This medicine is not only suitable for wind stroke but especially for wind strike and evil qi strike. It can also be taken for ordinary vomiting with excessive phlegm. If the aforementioned syndrome involves much anger, Xiao Xuming Decoction (Minor Continuation Life Decoction) with Antelope Horn is appropriate. For heat with thirst, remove Aconite Root from the decoction and add Gentian Root half qian. For confusion and erroneous speech, add Poria and Polygala root each half qian. For insomnia, add Sour Jujube Seed half qian. For inability to speak, add Bamboo Juice one conch shell measure. For those who are weak and powerless, remove Ephedra Stem and add Ginseng Root in equal amount to Ephedra. If the patient revives spontaneously, can speak and eat, but suffers from limb paralysis, with acute spasm or chronic dragging, lasting years without cure, take Modified Dixian Dan (Immortal Earth Pill) regularly. If diet, sitting, and lying are normal, but only aphonia exists, use Xiao Xuming Decoction removing Aconite Root and adding Acorus Tatarinowii Rhizome one qian. The method for treating wind: immediately upon onset, regulate qi; after prolonged duration, invigorate blood. This is an immutable principle for eternity. Healing via swallowing Huoluo Dan (Meridian-Unblocking Pill) with Siwu Tang (Four Substances Decoction) exemplifies this meaning. If one does not first regulate qi and resolve phlegm, but hastily uses Aconite and Typhonium, without invigorating blood, and merely uses Saposhnikovia Root, Gastrodia Rhizome, and Notopterygium Root, I have never seen it cured. Furthermore, seeing wind invading the skin and interstices treated with Camphor and Musk draws the wind into the bone marrow, making it even harder to treat; this should be deeply cautioned against. For facial deviation not yet corrected, apply peeled and mashed Castor Bean seeds to the unaffected side (right to left, left to right). Or apply fresh fish blood with a little Musk; applying it corrects the deviation immediately. For sudden collapse due to sneezing, stiffening, and unconsciousness, urgently blow Gleditsia Sinensis powder or Buwo San (Non-Sleeping Powder) into the nose, and pull the hair at the crown of the head to revive. Those who sneeze are treatable; those who do not are not. The classics say: Wind exits through sweat. Induce slight sweating, just as releasing the exterior. For exterior excess with no sweat, disperse and conquer. For exterior deficiency with spontaneous sweating, warm and release. If qi stagnation is present, it is difficult to treat; emesis is indicated. Purging is applicable when internal blockage by stool and urine causes interior excess. For three to five days without bowel movement, Ji Yao Sanhua Decoction (Essential Sanhua Decoction) or Hezi Soufeng Pills (Hezi Wind-Searching Pills) may be given. Elderly people should only use Runchang Wan (Intestine-Moistening Pill). Regulating qi refers to qi stagnation and depression, such as shoulder and arm numbness and pain, caused by the seven emotions. Wuyao Shunqi Powder (Lindera Regulating Qi Powder) and Bawei Shunqi Powder are appropriate. Regulating blood refers to cases without urgent exterior-interior symptoms, where blood weakness causes irregular outbreaks; Da Qinjiao Tang (Major Gentian Decoction) and Qianghuo Yufeng Tang (Notopterygium Preventing Wind Decoction) are given, combined with Huatan Wan (Phlegm-Resolving Pill).
