肝脏在五行中属木，木能生风。所谓“肝风”，是指肝脏自身产生的内风，而非外界侵入的邪气。它引发的病症多种多样。例如头痛、耳聋、眼睛红肿、手足麻木、筋脉跳动、肌肉抽搐（肉瞤）、眩晕、胁痛、呕吐食物等症状。如果误用祛风药进行疏散治疗，不仅无效，反而会助长病势的猛烈程度。
治疗方法应当遵循朱丹溪提出的“和阳熄风”原则（因为风邪往往挟带火邪）。可选用的药物包括牡丹皮、桑叶、黑栀子、白芍、豆豉皮、酸枣仁、茯神、麦冬、天冬、生地黄、盐水炒制的橘红、炒牛膝、羚羊角、钩藤、白蒺藜、甘草等，可以根据具体情况选用。因为肝体阴而用阳，性质刚强，适宜用柔润的药物来制约它；如果使用香燥的药物，就不是正确的治法。如果是寒邪郁结于肝木而生风，则应当辅助使用桂心、老姜等温通之品。
想要辨别是否为肝风，其脉象表现为弦而涣散，症状有口苦、味觉减退。这种病患发作迅速，只在顷刻之间。（风性善行而数变，故发病迅速）只要辨证准确，疗效也会像翻手掌一样容易。但是痊愈后必须服用养血滋肝泄木丸的药料，才能防止复发。
风从火中生发，但火未必从风中产生。然而火遇到风就会更加猛烈，所以治疗肝风时，必须配合调和阳气的方法；治疗肝火时，也应当加入熄风的药物。
肝火引起的病症，表现为双眼红肿疼痛、耳朵流脓、头痛、口苦且口渴、胁痛、胃痛、呕吐、咳嗽，或者吐血，颈部出现瘰疬（淋巴结核）。药用大黄、龙胆草、芦荟、夏枯草、黄连。以上五味药可以泻除肝脏的实火，其余情况应当选择清润柔和的药物，如桑叶、牡丹皮、羚羊角等来进行治疗。
胃痛和胁痛附属于肝火章节之后，是因为它们的治疗都专门责之于肝。肝喜条达舒畅，如果人含怒而不发泄，就会郁结而成火。火性炎上，克制其所胜的脾土，就会导致胃痛出现。轻症表现为不想吃东西、无法进食，重症表现为呕吐黄水，脉象必然弦，口必然苦。治疗应当解除其郁怒，再使用泄木安土理气的方药，如牡丹皮、桑叶、钩藤、白芍、广陈皮、炒延胡索、半夏、茯苓、通草、当归、川楝子；如果是久病导致胃虚，可以加入党参、生甜白术、炙甘草、老姜渣等，供选用。
胁痛也是由于肝经郁火沿着经络上行所致，治疗方法与胃病相同，只是可以使用逍遥散来疏解。大概来说，治疗胃痛以泄肝木为主，治疗胁痛则可以兼以散郁。有人问：使用越鞠丸怎么样？回答是：如果是郁结兼夹湿气和痰浊，越鞠丸为首选；如果是郁结导致血燥，则应以逍遥散为要务，这两个方剂的区别就在于此。如果是外感寒邪侵犯胃部导致的疼痛，患者痛苦到在床上爬滚，一刻也不能忍受，脉象必然沉伏，面色惨淡，这时应当使用温散之法，这一点不可不仔细辨别。
The Liver belongs to Wood in the Five Elements; Wood generates Wind. The so-called "Liver Wind" refers to wind generated internally by the Liver itself, rather than an external pathogenic factor. Its manifestations are diverse. Symptoms include headache, deafness, swollen eyes, numbness of the hands and feet, twitching of tendons, muscle fasciculations (rou kun), vertigo, hypochondriac pain, and vomiting of food. If one mistakenly uses wind-dispersing herbs for treatment, not only will it be ineffective, but it will also exacerbate the severity of the condition.
The treatment method should follow Zhu Danxi's principle of "Harmonizing Yang and Extinguishing Wind" (since wind often carries fire). Herbs that can be selected include Radix Paeoniae Rubra (Danpi), Folium Mori (Sangye), Fructus Gardeniae Praeparatus (Heizhi), Radix Paeoniae Alba (Baishao), Pericarpium Sojae Fermentatum (Douchi Pi), Semen Ziziphi Spinosae (Zaoren), Sclerotium Poriae Cocos (Fushen), Radix Ophiopogonis (Maidong), Radix Asparagi (Tian dong), Rhizoma Rehumatis Preparatum (Shengdihuang - *Note: Text says Shengdi, usually Rehmanniae Radix*), Tangerine Peel stir-fried with salt water (Yan shui chao Juhong), Achyranthes Bidentata Root stir-fried (Chao Niuxi), Cornu Saigae Tataricae (Lingyangjiao), Ramulus Uncariae cum Uncis (Gouteng), Fructus Tribuli (Bajili), and Radix Glycyrrhizae (Gancao), which can be selected according to the situation. Since the Liver is a viscera that prefers softness and dislikes dryness, it is best treated with moistening and softening herbs; using aromatic and drying herbs is incorrect. If cold stagnation in the Liver Wood generates wind, warming agents such as Cortex Cinnamomi (Guixin) and Rhizoma Zingiberis Recens (Laojiang) should be added as adjuvants.
To differentiate Liver Wind, the pulse is wiry and scattered, accompanied by bitter taste and loss of taste. The onset of this disease is rapid, occurring within moments. (Wind moves swiftly.) Once the syndrome is accurately identified, the therapeutic effect is achieved as easily as turning over a hand. However, after recovery, one must take the formula for Nourishing Blood and Moistening the Liver while Draining Wood (Yangxue Zigan Xuemu Wan) to prevent recurrence.
Wind is generated from Fire, but Fire does not necessarily originate from Wind. However, when Fire encounters Wind, it becomes more fierce. Therefore, when treating Liver Wind, one must harmonize Yang; when treating Liver Fire, one should also add herbs to extinguish Wind.
Liver Fire causes symptoms such as red and painful eyes, purulent discharge from the ears, headache, bitter taste with thirst, hypochondriac pain, stomach pain, vomiting, cough, hematemesis, and scrofula (luoli) on the neck. The prescription includes Radix et Rhizoma Rhei (Dahuang), Radix Gentianae Longdancao (Longdancao), Aloe (Luhui), Herba Prunellae Spicae (Xiakucao), and Rhizoma Coptidis (Huanglian). These five herbs drain the excess fire of the Liver. For other cases, one should select clearing and softening herbs, such as Sangye, Danpi, and Lingyangjiao, for treatment.
Stomach pain and hypochondriac pain are appended after the section on Liver Fire because their treatment specifically targets the Liver. The Liver desires free flow and dispersion. If anger is suppressed and not expressed, it stagnates and transforms into Fire. Fire has a nature of flaming upward and insulting its conquered element (Earth/Spleen-Stomach), leading to stomach pain. Mild cases present with lack of appetite and inability to eat; severe cases present with vomiting of yellow fluid. The pulse must be wiry, and the mouth bitter. Treatment should resolve the depression and anger, followed by formulas and herbs to drain Wood, calm Earth, and regulate Qi, such as Danpi, Sangye, Gouteng, Baishao, Guangpi (Chenpi), Chao Yanhusuo, Banxia, Fuling, Tongcao, Danggui, and Chuanshanlong (Chuanlianzi); for chronic illness causing Stomach deficiency, Dangshen, Sheng Baizhu, Zhigancao, and Laojiangzha may be added.
Hypochondriac pain is also caused by stagnant Fire in the Liver Meridian moving upward along the channel. The treatment method is the same as for stomach pain, except that Xiaoyao San can be used to disperse it. Generally, treating stomach pain focuses on draining Liver Wood, while treating hypochondriac pain can additionally focus on dispersing depression. One might ask: How about Yueju Wan? The answer is: If depression is complicated by dampness and phlegm, Yueju Wan is the priority; if depression leads to blood dryness, Xiaoyao San is essential. This distinguishes the two formulas. If external cold invades the Stomach causing pain, where the patient rolls on the bed and floor in unbearable agony, the pulse will be deep and hidden, and the complexion pale and dull. In this case, warming and dispersing methods must be used, and this distinction cannot be overlooked.
