*Ji Bing Ji Yao* (Essentials of Pathogenesis) states: Wind pathogen is essentially heat; when heat is excessive, wind moves. Treatment should employ stillness to overcome dryness, which refers to nourishing the blood. Treatment requires avoiding excessive sweating and also avoiding excessive purgation. Excessive sweating will deficiency the Wei Qi (Defensive Qi), while excessive purgation will damage Ying Blood (Nutritive Blood). Treatment should focus on the meridians. Although there are contraindications for sweating and purgation, there is a distinction between involvement of the Fu organs (Hollow Organs) and the Zang organs (Solid Organs). Involvement of the Fu organs often affects the four limbs, presenting with exterior syndrome symptoms such as floating pulse, aversion to wind and cold, stiffness, and numbness. Involvement of the Zang organs often stagnates in the nine orifices, presenting with flaccid lips, loss of voice, deafness, nasal congestion, blurred vision, and constipation. For involvement of the Fu organs, diaphoresis (sweating method) is appropriate. For involvement of the Zang organs, purgation is appropriate. Once the interior and exterior are harmonized, treatment should focus on the meridians, using substantial medicinal tonics for nourishment.

*Fa Ming* (Elucidations) states: Invasion of the vessels and collaterals leads to deviation of the mouth and eyes; invasion of the Fu organs leads to disability of the joints and limbs; invasion of the Zang organs endangers life. The treatments for these three conditions are entirely different. For invasion of the vessels and collaterals, if there are exterior manifestations of the Six Channels (Taiyang, Yangming, Shaoyang, Taiyin, Shaoyin, Jueyin), modify Xiao Xuming Tang (Minor Cinnamon Twig Decoction). For invasion of the Zang organs, if there is obstruction of stool and urine internally, use Sanhua Tang (Three Transformations Decoction) or similar formulas to unblock. If there are no exterior manifestations of the Six Channels and no internal obstruction of stool and urine, nourish blood and promote Qi circulation, primarily using Da Qinjiao Tang (Greater Gentian Root Decoction) or Qianghuo Yufeng Tang (Notopterygium Decoction for Preventing Wind).

Xu Xuwei (Scholar Xu) states: What the world calls "Qi Zhong" (Stroke caused by Qi disorder), although not explicitly recorded in medical formularies, arises from sudden anger damaging Yin, sudden joy damaging Yang, and persistent worry causing Qi rebellion. One often contracts this disease. The patient suddenly feels saliva surging, dizziness, and blockage, with tight jaw. If treated immediately with stroke medications, it often leads to death. It is only appropriate to administer Suhexiang Wan (Styrax Pill), after which the patient will awaken. Then, regulate according to cold, heat, deficiency, and excess, and all cases can be cured. The Classics state: Sudden aphonia without cause occurs because Lung Qi does not reach its destination; if untreated, it heals itself, referring to sudden Qi rebellion. When Qi returns to normal, the condition resolves. If this is indeed the case, medication may even be unnecessary.

*Yu Ji Wei Yi* (Subtle Meanings of the Jade Machine) states: Qi Zhong is caused by the movement of internal fire due to the Seven Emotions. Qi rebellion occurs due to underlying deficiency. Using Suhexiang Wan (Styrax Pill) can unblock the meridians and collaterals; its fierce and decisive nature is like destroying dry wood and pulling apart rotten timber, which is likely unsuitable for those with deficient Qi and Blood. The later statement about self-recovery without treatment serves as a warning against medication errors, actually surpassing the harm caused by incompetent physicians' mistakes.
