The *Huangdi Neijing* (Yellow Emperor's Inner Canon) states: "All wind diseases characterized by tremors and vertigo belong to the Liver." "Diao" refers to shaking or trembling. "Xuan" refers to dizziness, confusion, and a sensation of rotation. These conditions arise from the deficiency of Metal (Lung) failing to control Wood (Liver), leading to an exuberance of Wood generating Wind, which in turn stirs up Fire. Both Wind and Fire belong to Yang and are dynamic in nature; when they contend with each other, it results in a sensation of rotation. The *Huangdi Neijing* further states: "Deficiency at the upper part leads to vertigo," indicating that righteous Qi is deficient while pathogenic Wood invades. It also states: "Kidney deficiency causes heaviness of the head and swaying, insufficiency of the Marrow Sea leads to spinning sensations and tinnitus," all emphasizing pathology due to insufficiency. Zhang Zhongjing discussed vertigo primarily in terms of Phlegm-Fluids, while Zhu Danxi followed Liu Wansu’s theory, asserting that without Phlegm there is no vertigo and without Fire there is no fainting, both emphasizing pathology due to excess. Why are the views of former sages and later worthies so contradictory? In my youth, I read Zhang Jingyue’s works, which exclusively advocated tonifying deficiency. Following this approach yielded no effect. Upon further searching ancient medical teachings, I realized that Zhang Jingyue understood the concepts of "deficiency" and "excess" too rigidly and failed to thoroughly comprehend the mechanisms behind "Wind" and "Fire." Essentially, "Wind" here does not refer to external pathogenic Wind, but rather to Jueyin Wind-Wood. It resides together with Shaoyang Ministerial Fire. When Jueyin Qi rebels upward, Wind generates and Fire erupts; hence, Liu Wansu established his theory on Fire and Wind. When Wind arises, it inevitably carries the force of Wood to overcome Earth (Spleen/Stomach). When Earth becomes diseased, body fluids accumulate to form Phlegm; thus, Zhang Zhongjing based his theory on Phlegm-Fluids, and Zhu Danxi on Phlegm-Fire. Ultimately, the Kidney is the mother of the Liver. The Kidney stores Essence; when Essence is deficient, the Marrow Sea becomes empty, causing heaviness of the head. Therefore, the *Huangdi Neijing* bases its theory on Kidney deficiency and insufficiency of the Marrow Sea. Statements regarding "deficiency" refer to the root cause of the disease, while statements regarding "excess" refer to the clinical manifestations. The underlying principle is consistent; however, Liu Wansu and others merely focused on clearing Fire, expelling Wind, and resolving Phlegm, without understanding the origin of Wind, Fire, and Phlegm. I only diagnose as "Upper Excess" when the pulse at the Cun Kou (radial artery) is slippery and feels firmer upon deep pressure, treating it according to Zhu Danxi using Wine-processed Dahuang (Rhubarb Root). If the Cun Kou pulse is large but dissipates upon pressure, I diagnose as "Upper Deficiency" and treat with a single herb, Lurong (Deer Antler Vinegar Preparation). If the Cun Kou pulse is minute, I use Buzhong Yiqi Tang (Tonify the Middle and Augment the Qi Decoction), or a paste made from Huangqi (Astragalus Root) and Baizhu (Atractylodes Rhizome) mixed with Banxia (Pinellia Tuber) powder. However, to nourish the upper part, one must irrigate the root. Formulas such as Zhengyuan San, Liuwei Dihuang Wan (Six-Ingredient Pill with Rehmannia), and Shenqi Dihuang Wan (Eight-Ingredient Pill with Rehmannia) are excellent preparations for vigorously tonifying the Water and Fire (Yin and Yang) of the Kidney. Yi and Gui share the same source (referring to the kinship between Liver and Kidney); treating the Kidney is equivalent to treating the Liver; treating the Liver extinguishes Wind; extinguishing Wind reduces Fire; reducing Fire treats Phlegm. Profound understanding and application depend on the practitioner and cannot be fully conveyed through writing. Herbs such as Gouteng (Uncaria Rhynchophylla), Yuzhu (Polygonatum Odoratum Rhizome), Juhua (Chrysanthemum Flower), and Tianma (Gastrodia Rhizome), which are soft and moistening agents for extinguishing Wind, can be added or subtracted from various formulas to achieve rapid effects.
