地。因此骨繇（关节摇动不稳）的病证，应当取足少阳胆经的穴位进行治疗。要视其邪气的有余或不足来辨证施治。所谓骨繇，是指关节弛缓而摇动不定的症状。这叫做“繇”，就是摇动的意思。应当探究其根本原因。
现在考察那些因筋脉痿软而导致颤抖动摇的病证，应当取窍阴穴和窗笼穴治疗。但“窗笼”这一穴位名称目前尚无确切考证，恐怕是指手太阳小肠经的听宫穴。因为这里是手足太阳、手足少阳三条经脉交会的地方。否则，也可能是指听会穴，暂且留待日后另行考证。

肝脏重四斤四两。左边有三叶，右边有四叶，共有七叶。它附着在脊柱的第九椎处。它的功能主治部位在左侧，而其实质脏器位于右侧。它在肾脏的前面，并与胃相邻。
东方对应青色，气机通于肝脏。开窍于目。精气藏于肝。肝病容易引发惊骇。其味为酸。其五行属性类同草木。其对应的牲畜是鸡。其气味为臊。其声音为呼。其体液为泪。其颜色为青。
东方生风，风生木，木生酸，酸生肝。肝主管筋脉，筋脉滋养心。肝开窍于目。在天体现为玄妙，在人体现为道，在五色中体现为苍色。在五音中为角音。在五声中为呼声。在变动中表现为握拳状抽搐。在窍窍中为目。在五味中为酸味。在五志中为怒。怒伤肝，悲能胜怒。风邪伤筋，燥能胜风。酸味伤筋，辛味能胜酸。
肝，是将军之官，负责决断和行动。
肝，是疲劳的本源，也是魂的居所。其荣华表现在爪甲，其充养体现在筋脉，以此化生血气。这属于阳中的少阳，与春气相通。肝与筋相合。其荣华在爪甲。肺制约肝。
肝气通达于目，目功能调和，就能分辨黑白。（“知”字当作“见”字解）
肝气虚弱时，会梦见菌香和生长的草。如果得其时令（春季三个月），则会梦见伏在树下不敢起身。
人卧睡时，血液回归于肝。目得到血的濡养就能视物，足得到血的濡养就能行走，手掌得到血的濡养就能握持，手指得到血的濡养就能摄取物体。肝的颜色为青，想要知道像苍璧那样的润泽，而不喜欢像蓝草那样（暗沉）。（以上内容均出自《素问》）
肝属青象木，木遇水则浮，为何肝遇水却下沉呢？回答是：肝并非纯粹的木。乙（阴木）对应角音，大声言阴阳，是从属于甲（阳木）的。肝气熟透反而上浮的，是因为乙木当归附于甲木，这是极则反变的道理。〔出自《难经》〕
肝为什么有两叶呢？回答是：肝属东方木，对应春季。万物开始生长，尚幼小，心意无所亲附。离太阴（冬）尚近，离太阳（夏）不远。仍有两叶，也顺应木的特性。〔出自《难经》〕
肝气绝，则筋脉收缩牵引睾丸并导致舌卷曲。肝与筋相合。筋汇聚于生殖器并联络于舌根。所以血脉不能荣养筋脉，就会导致筋脉收缩紧急。筋脉收缩紧急，就会牵引睾丸和舌头。所以出现舌卷缩、睾丸上缩的症状。这是筋先死的表现，庚日病情加重，辛日死亡。
Earth. Therefore, for the condition of *Gu Yao* (instability and trembling of joints), one should select points from the Shaoyang Gallbladder Meridian. One must examine whether the pathogenic factor is in excess or deficiency to guide treatment. The term "Gu Yao" refers to the symptom of joints being lax and trembling; this is called "Yao," meaning shaking. One must investigate the root cause.
Currently, regarding conditions where tendons are flaccid leading to tremors and shaking, one should select Qiaoyin (GB43) and Chuanglong. However, "Chuanglong" has not been definitively verified; it is likely referring to Tinggong (SI19) of the Hand-Taiyang Small Intestine Meridian. This is because it is the convergence point of the Hand and Foot Taiyang and Shaoyang meridians. Alternatively, it might be Tinghui (GB2), pending further verification.
[Image: Liver Diagram pj-j28.bmp]
The liver weighs four jin and four liang. It has three lobes on the left and four on the right, totaling seven lobes. It attaches to the ninth thoracic vertebra of the spine. Its functional manifestation is on the left, while its physical organ resides on the right. It is located anterior to the kidneys and adjacent to the stomach.
The East corresponds to the color green, with qi connecting to the Liver. It opens into the eyes. Essence is stored in the Liver. Liver disorders often manifest as fright and terror. Its flavor is sour. Its elemental category is Wood and Plants. Its associated animal is the chicken. Its odor is musky/fishy. Its sound is a shout. Its fluid is tears. Its color is green.
The East generates Wind; Wind generates Wood; Wood generates Sour; Sour generates the Liver. The Liver governs the sinews (tendons); the sinews nourish the Heart. The Liver opens into the eyes. In Heaven, it manifests as profound mystery; in Humanity, it manifests as the Dao; in colors, it manifests as dark green/cyan. In musical tones, it is Jue (Ang); in vocal sounds, it is shouting; in pathological movements, it is grasping/clenching; in orifices, it is the eyes; in flavors, it is sour; in emotions, it is anger. Anger injures the Liver; grief overcomes anger. Wind injures the sinews; dryness overcomes wind. Sour injures the sinews; pungency overcomes sour.
The Liver is the Official of the General, responsible for decision-making and action.
The Liver is the root of endurance against fatigue and the dwelling place of the Hun (Ethereal Soul). Its brilliance manifests in the nails, and it nourishes the sinews, thereby generating blood and qi. This constitutes the Lesser Yang within Yang, communicating with the Qi of Spring. The Liver harmonizes with the sinews. Its brilliance is seen in the nails. The Lung controls the Liver.
Liver qi connects to the eyes. When the eyes are harmonious, one can distinguish black and white. ("Zhi" [know] should be read as "Jian" [see].)
When Liver qi is deficient, one dreams of fragrant mushrooms and growing grass. If this occurs during its proper season (the three months of Spring), one dreams of lying prostrate under a tree, afraid to rise.
When a person sleeps, blood returns to the Liver. The eyes receive blood and thus can see; the feet receive blood and thus can walk; the palms receive blood and thus can grasp; the fingers receive blood and thus can hold objects. The color of the Liver is green. One desires the luster like that of a dark jade disc, not the dullness of blue dye. (All above content is from *Su Wen*)
The Liver is green and symbolizes Wood. Wood floats on water, so why does the Liver sink in water? The answer is: The Liver is not pure Wood. Yi (Yin Wood) corresponds to the Jue tone. Speaking broadly of Yin and Yang, it follows Jia (Yang Wood). When Liver qi matures and floats upward, it is because Yi Wood returns to Jia Wood; this is the principle of reversal at the extreme. [From *Nan Jing*]
Why does the Liver have two lobes? The answer is: The Liver belongs to Eastern Wood and corresponds to Spring. All things begin to grow; they are still young and small, with no specific attachment. They are close to Taiyin (Winter) but not far from Taiyang (Summer). Having two lobes also conforms to the nature of Wood. [From *Nan Jing*]
When Liver qi ceases, the sinews contract, pulling the testicles and causing the tongue to curl. The Liver harmonizes with the sinews. Sinuses gather at the genitalia and connect to the base of the tongue. Therefore, if the vessels fail to nourish the sinews, the sinews will contract and become tight. Tight sinews pull the testicles and tongue, resulting in a curled tongue and retracted testicles. This indicates the death of the sinews first; the condition worsens on Geng days and leads to death on Xin days.
