If the urine volume is low, diuretic drugs should not be used to promote urination. Since spontaneous sweating (Zihan) has already occurred, body fluids (Jinye) are lost from the exterior, causing urine output to decrease naturally. If diuretics are administered at this time, Ying Qi (Nutritive Qi) and Wei Qi (Defensive Qi) will become depleted, failing to control Fire pathogenic factors, thereby exacerbating irritability and heat. One should wait for the fever to subside and sweating to cease, after which urination will normalize on its own. In cases with these concurrent symptoms, promoting urination is a major contraindication in the treatment of Yangming Channel diseases.

Yuan Rong stated: Diseases caused by dampness from alcohol can also manifest as Bi syndrome (Obstruction Syndrome), presenting with deviation of the mouth and eye, hemiplegia, and symptoms resembling Wind stroke. However, tongue stiffness and speech impediment result from the expulsion of damp-heat toxins; thus, it should not be treated as a Wind disease using diaphoretic methods. The discussion in *Yanyi Lun* is highly appropriate, and the views in *Yijian Fang* are consistent with this.

Based on this analysis, it is evident that conditions such as deviation of the mouth and eye and hemiplegia are not solely caused by Wind pathogens. Furthermore, all six climatic pathogens (Six Evils) can invade the human body, presenting with symptoms such as spasms, convulsions, and loss of consciousness. Therefore, differentiation must be strictly based on pulse signs and clinical manifestations.

Yan Yonghe stated: When a person's Yuan Qi (Primal Qi) is strong, Ying and Wei Qi are harmonious, and the interstices (Couli) are dense, how can external pathogens cause harm? However, due to emotional disturbances (Seven Emotions), improper diet, or overwork, the True Qi may first become deficient, leaving Ying and Wei Qi empty and the defensive barrier lax, allowing pathogens to enter through the deficiency and cause disease. If the etiology is internal (Seven Emotions), the treatment should focus on regulating Qi rather than treating Wind. If the etiology is external (Six Excesses), one should first regulate Qi and then treat according to the specific Six Excesses involved. This is an excellent method, and Bawei Shunqi San (Eight-Ingredient Decoction to Smooth Qi) is suitable.

In my opinion, the concept that "True Qi becomes deficient first, Ying and Wei Qi become lax, and pathogens enter through the deficiency" expands upon previous theories. Given that both deficiency and pathogenic invasion exist, tonifying deficiency and dispersing pathogens is logically necessary. The text mentions only "regulating," implying that because pathology causes Qi stagnation and obstruction, regulating it to restore smooth flow allows True Qi to recover spontaneously and pathogens to dissipate. Unfortunately, this explanation is not detailed enough. Moreover, the treatment of Zhongfeng (Wind Stroke) is not limited to this single approach.

Scholar Xu stated: What is commonly referred to as "Qi Zhong" (Qi Obstruction) is not explicitly recorded in medical formularies. However, violent anger injures Yin, excessive joy injures Yang, and persistent sorrow leads to Qi rebellion (Jue Ni). Such individuals often contract this disease, suddenly experiencing flooding of saliva, coma, and tight closure of the jaw. If treated immediately with medications for Wind Stroke, death often results. It is advisable to administer Suhexiang Wan (Styrax Pill) to induce awakening, followed by regulation based on Cold, Heat, Deficiency, and Excess patterns, leading to complete recovery. The *Classic of Difficult Issues* states: "Sudden aphonia without apparent cause, with absent pulse, will resolve without treatment." This refers to sudden Qi rebellion; once Qi returns to normal, the condition resolves. Examining this, even without medication, the body can recover spontaneously.

The theory of "Qi Zhong" refers to the movement of internal Fire caused by Seven Emotions, leading to Qi rebellion due to underlying deficiency. Using Suhexiang Wan to unblock meridians relies on its potent nature, akin to pushing over dry wood or breaking rotten timber; this is likely unsuitable for those with deficient Blood and Qi. The statement that "non-treatment leads to self-recovery" serves as a warning against therapeutic errors, suggesting that doing nothing is preferable to being mismanaged by incompetent physicians.
