种植栽培的川芎，其根部块状较大，质地坚实且富含油脂。野生生长的则细小瘦弱，气味辛苦。产于四川的称为川芎，其根块坚硬沉重、圆润结实，颜色黄而不泛油光，形状像雀脑，咀嚼时味道甘辛（因其味甘辛，在方剂应用中最为契合），这是上等品。它治疗血虚及胎产疾病效果极佳；焦枯者不可使用。
西芎产于关中地区，颜色微青，专门治疗偏头痛。但对于产后血虚和气虚的患者，均不可服用。还有一种西芎，其实体大而坚重，内外皆白，锉碎后成片状，这也属于西芎，但不入药。台芎产于浙江台州，仅用于疏散风邪、驱除湿气。抚芎产于江西抚州，体型小且中间空虚，只能开郁散气，宽胸行气以缓解经络疼痛，这些都不适合血虚患者使用。
川芎根味辛苦，性温，气浓味薄，性质浮而升，属阳。它是少阳经的本经引经药，归入手足厥阴经的气分。生用性温，熟用性寒。（李当之注）白芷为其使药，畏黄连。主治中风入脑、头痛血虚、面部游风引起的头痛、胁部风痛。治疗各种寒冷之气引起的心腹坚痛、寒痹筋挛缓急。能破除症结宿血，滋养新血，疏理肝气，补益肝血，润燥养肝，补益风虚，开郁理气，行滞气，燥湿止泻痢。蜜丸可治风痰，以及一切痈疽疮疡肿痛，促进肌肉生长、排脓。更治疗妇人血气各类疾病。（诸本草记载）方书中还用于治疗眼疾及鼻、耳、唇、齿、喉、舌、胡须头发等部位的疾病，中风眩晕，中寒，伤湿，伤劳倦郁结，往来寒热疟疾，破伤风抽搐，震颤癫痫痉挛，颈项强痛，虚劳自汗、盗汗虚烦，循衣撮空，谵妄惊悸，健忘失眠，不能进食，喘厥咳嗽呕吐，失音，鼻衄、耳衄，吐血蓄血，尿血、便血等各种出血证，心痛、胃脘痛、腰痛，脚气鹤膝风，着痹、痛痹、行痹，消渴黄疸，痰饮水肿，胀满泄泻，痢疾脱肛，大便不通，淋证疝气。它能上行头目，下行血海，助清阳之气，去除头部湿气，因此治疗各经头痛。（洁古注）头痛必用川芎，如果不愈，再加各经引经药：太阳经加羌活，阳明经加白芷，少阳经加柴胡，太阴经加苍术，厥阴经加吴茱萸，少阴经加细辛。（东垣注）另外头痛剧烈的，加蔓荆子；头顶和脑痛，用川芎；头顶痛加藁本。如果有热者，川芎不能单独治疗，另有清空膏等方剂。（这两条专门治疗风寒头痛）川芎是血中的气药。扁鹊说，味酸是因为它入肝。（仲淳注）肝苦急，以辛味补之，所以血虚者适宜用川芎；以辛味散之，所以气郁者适宜用川芎。（濒湖注）味辛气温，但只能升散，而不能下守。血贵宁静，不贵燥动。四物汤中使用川芎是为了畅通血中之气，使血自生，并非认为它能直接养血。即在痈疽及诸疮肿痛药中多用川芎，是因为它入心经而能散火邪。（丹溪注）另外郁结在中焦，需用抚芎开提其气使之上升，气升则郁结自降，所以抚芎总解诸郁，直达三焦，为通调阴阳气血的使者。在治疗湿泻的药中，常加麦曲和川芎，疗效立竿见影。（即《左传》中治疗“河鱼腹疾”的意思）血痢已通但疼痛不止的，乃是阴亏气郁，加川芎为佐药，气行血调，病立止。合四物汤，加荆芥、白芷、白术、甘草，治疗破伤风。冬季加桂枝。同当归、地黄、芍药、干漆、延胡索、五灵脂、京三棱、牡蛎粉同用，治疗血瘕。同白芷、茜根、黄芩、银花、生地同用，能排脓消瘀血。同甘菊、当归、地黄、天冬、白芍、炙甘草同用，专主血虚头痛。火盛者加童便服用。同归尾、桂心、牛膝同用，治疗子死腹中。同续断、熟地、白胶、杜仲、山萸肉、五味子、人参、黄芪、枣仁同用，治疗血崩久不止。
风热头痛：川芎一钱，茶叶二钱，水一钟，煎至五分，食前热服。
风热上冲，头目眩晕，或胸中不利：川芎、槐子各一两，研为末，每服三钱，用茶清调下。胸中不利者，以水煎服。
首风旋晕，及偏正头疼，多汗恶风，胸膈痰饮：川芎一斤，天麻四两，研为末，炼蜜丸如弹子大，每嚼服一丸，茶清送下。
崩中下血，昼夜不止：千金方用川芎一两，清酒一大盏，煎取五分，徐徐进服。圣惠方加生地汁二合。
〔论〕川芎三月生苗，禀受春气已深，故性温。至八月才开始在根下结出川芎，而在九十月采收。过晚采收则品质虚恶，这又是得金气之全者，所以其味由甘转辛，辛胜甘劣。气禀于温而生，味结于根下，又属辛甘之阳，所以气浓升浮，合于人身天地之肺而至于极上。因此此物能畅达真气，但过用也能耗散真气。遍阅方书主治，大体上能达阳于阴中，即能贯阴于阳中，始终在血分畅其气，所以海藏专以益肝为言，说搜肝风、补肝血、润肝燥，却又说补风虚，因为血脏原属风脏，惟能达阴中之阳，则风化斯行而诸寒冷气自散也。明于阴中之阳不化，可以悟到诸血证之治悉本风虚；明于风虚之义，又可以悟到肝风并肝血虚、肝气燥的缘故了。为何又入手厥阴气分？盖肝之上行而媾于肺，肺即媾于肝而下行，其下行者乃合于足厥阴同气之心包络以生血焉，总以全肝之用而已。人身清阳能升，浊阴能降，此气化血生之原也。川芎上至巅顶，下至血海，不惟握升降清浊之枢以为化原，实能由风脏血脏之化机以为生育。故治血虚头痛为圣药。至于调众脉，破症结宿血，养新血，以及吐衄溺血，皆可推风虚之义以治之。惟风淫者不任受耳。总之，阳陷阴中及阳不能畅阴之证，此味乃所宜投。如下之阴虚不守而阳僭于上，及上之阳盛而阴不能为之主者，妄投适以滋害，宁止于久服乃散真气哉。（用川芎止欲其畅阴，不可用之虚阴，畅阴虚阴之异，粗工多不致察。）川芎之治，在目为最，即头痛犹次之，以肝开窍于目，而人身六气之首，惟风司之，肝固风脏，又即血脏也。本此风升之元气，以达阴中之阳而上行。（此经所谓通天者生之本也）即俾阳中之阴皆畅，而血和于气以化，是所谓目得血而能视者也。（玩此则于补风虚之义更畅）更取消瘅之肾沥散以为肾气虚损者，用磁石为君，却以川芎及麦冬为臣，其他益阴气滋阴血之味止为佐，可知元气为阴中之阳，而川芎之与麦冬为臣者，固就阴中透阳之义也。是则在下行者，必裕阴而乃透其阳以上。在上凡病上盛下虚，火炎咳呕，咽干口燥，发热渴烦，及自汗易汗盗汗者，法咸忌之。（仲淳注）骨
Cultivated Xiong (Ligusticum chuanxiong) has large, solid, and oily root tubers. Wild-grown ones are slender, thin, and pungent-bitter in taste. Those produced in Sichuan are named Chuanxiong (Sichuan Lovage Rhizome); their root tubers are hard, heavy, round, and solid, with a yellow color that is not oily, resembling sparrow brains. When chewed, they taste sweet and pungent (their sweet and pungent flavor makes them most suitable for clinical application), which represents the superior grade. They are excellent for treating blood deficiency and disorders related to pregnancy and childbirth; those that are scorched or dried out should not be used.
Xi Xiong (Western Lovage) is produced in the Guanzhong region, has a slightly greenish color, and is specifically used to treat hemi-cephalgia (migraine). However, it should not be administered to patients with postpartum blood deficiency or qi deficiency. Another type of Xi Xiong is large, hard, and heavy, white inside and out, and slices into pieces when chopped; this also belongs to Xi Xiong but is not used in medicine. Tai Xiong is produced in Taizhou, Zhejiang, and is only used to dispel wind and drive away dampness. Fu Xiong is produced in Fuzhou, Jiangxi; it is small and hollow in the center, capable only of resolving stagnation, dispersing qi, relaxing the chest, and moving through meridians to relieve pain; these are not suitable for use in cases of blood deficiency.
The root tastes bitter and pungent, is warm in nature, has a strong aroma but weak flavor, and its action is floating and ascending, belonging to Yang. It is the guiding herb for the Shaoyang channel, entering the Qi aspect of the Hand and Foot Jueyin channels. Raw usage is warm, while cooked usage is cold. (Note by Li Dangzhi) Angelicae Dahuricae Radix (Bai Zhi, 白芷) serves as its assistant herb; it fears Coptidis Rhizoma (Huang Lian, 黄连). It primarily treats wind-stroke invading the brain, cephalgia due to blood deficiency, wandering wind on the face causing headache, and wind-pain in the hypochondrium. It treats various cold pathogens causing hardness and pain in the heart and abdomen, cold bi-syndrome with tendon spasms and stiffness. It breaks up masses and old blood stasis, nourishes new blood, searches out liver qi, tonifies liver blood, moistens liver dryness, tonifies wind-deficiency, opens stagnant qi, moves stagnant qi, dries dampness, and stops diarrhea and dysentery. Honey pills can treat wind-phlegm and all types of carbuncles, sores, ulcers, swelling, and pain, promoting flesh growth and expelling pus. It further treats various blood and qi disorders in women. (Recorded in Various Materia Medica) Medical texts also indicate its use for eye diseases and disorders of the nose, ears, lips, teeth, throat, tongue, beard, and hair; wind-stroke with vertigo; cold invasion; injury from dampness, fatigue, and stagnation; alternating chills and fever malaria; traumatic tetanus with convulsions; tremors, epilepsy, and spasms; stiffness and pain in the neck and nape; consumptive disease with spontaneous sweating, night sweats, and vexation; picking at clothes and empty grasping; delirium and palpitations; forgetfulness and insomnia; inability to eat; wheezing, vomiting, cough, and syncope; aphonia; epistaxis and auricular hemorrhage; hematemesis and blood retention; hematuria and hematochezia, and other bleeding manifestations; heart pain, epigastric pain, and lower back pain; gout and knee deformity; fixed bi, painful bi, and wandering bi; diabetes mellitus and jaundice; phlegm-fluid retention and edema; distension, fullness, diarrhea, and rectal prolapse; constipation; strangury and hernia. It ascends to the head and eyes and descends to the Blood Sea, assisting clear Yang qi and removing dampness from the head, thus treating headaches of all channels. (Note by Zhang Congzheng/Jiegu) Cephalgia must use Chuanxiong; if ineffective, add channel-guiding herbs: Taiyang channel uses Notopterygii Rhizoma et Radix (Qiang Huo, 羌活), Yangming channel uses Angelicae Dahuricae Radix (Bai Zhi, 白芷), Shaoyang channel uses Bupleuri Radix (Chai Hu, 柴胡), Taiyin channel uses Atractylodis Rhizoma (Cang Zhu, 苍术), Jueyin channel uses Evodiae Fructus (Wu Zhu Yu, 吴茱萸), Shaoyin channel uses Asari Radix et Rhizoma (Xi Xin, 细辛). (Note by Li Dongyuan/Dongyuan) Additionally, for severe headaches, add Viticis Fructus (Man Jing Zi, 蔓荆子); for vertex and brain pain, use Chuanxiong; for vertex pain, add Ligustici Wallichii Rhizoma et Radix (Gao Ben, 藁本). If there is heat, Chuanxiong alone cannot treat it; there are other formulas like Qingkong Gao (Clear Empty Paste). (These two points specifically treat wind-cold cephalgia) Xiong is a qi-moving herb within the blood. Bian Que stated that its sour taste indicates its entry into the Liver. (Note by Chen Zhongchun/Zhongchun) The Liver suffers from tension; pungency tonifies it, so it is suitable for blood deficiency. Pungency disperses, so it is suitable for qi stagnation. (Note by Li Shizhen/Binqu) Its flavor is pungent and warm, but it can only ascend and disperse, not descend and retain. Blood values tranquility, not agitation. In Si Wu Tang (Four Substances Decoction), Chuanxiong is used to circulate qi within the blood, allowing blood to generate itself; it is not claimed to directly nourish blood. Even in formulas for carbuncles and sores where it is often used, it is because it enters the Heart channel and can dissipate fire pathogens. (Note by Zhu Danxi/Danxi) Furthermore, for stagnation in the Middle Jiao, Fu Xiong is needed to lift the qi; when qi ascends, stagnation naturally descends. Thus, Fu Xiong resolves various stagnations, reaches the Triple Burner directly, and acts as an envoy to unblock Yin and Yang and blood and qi. In formulas treating damp-diarrhea, Mai Qu (Medicated Leaven) and Chuanxiong are often added, yielding immediate results (referencing the treatment of "river fish abdominal disease" in Zuo Zhuan). For bloody dysentery that has cleared but pain persists, it is due to Yin deficiency and qi stagnation; adding Chuanxiong as an assistant herb regulates qi and blood, stopping the pain immediately. Combined with Si Wu Tang, plus Schizonepetae Herba (Jing Jie, 荆芥), Angelicae Dahuricae Radix (Bai Zhi, 白芷), Atractylodis Macrocephalae Rhizoma (Bai Zhu, 白术), and Glycyrrhizae Radix et Rhizoma (Gan Cao, 甘草), it treats traumatic tetanus. In winter, add Cinnamomi Ramulus (Gui Zhi, 桂枝). Combined with Angelicae Sinensis Radix (Dang Gui, 当归), Rehmanniae Radix (Di Huang, 地黄), Paeoniae Radix Alba (Bai Shao, 白芍), Drynariae Rhizoma? No, Gan Qi (Dry Lacquer? Likely typo for something else, keeping original name), Corydalis Rhizoma (Yan Hu Suo, 延胡索), Trogopterori Faeces (Wu Ling Zhi, 五灵脂), Curcumae Radix (Jing San Leng, 京三棱), and Ostreae Concha (Mu Li, 牡蛎), it treats blood masses. Combined with Angelicae Dahuricae Radix (Bai Zhi, 白芷), Rubiae Radix et Rhizoma (Qian Cao, 茜根), Scutellariae Radix (Huang Qin, 黄芩), Lonicerae Japonicae Flos (Jin Yin Hua, 银花), and Rehmanniae Radix Preparata (Sheng Di Huang, 生地), it expels pus and eliminates blood stasis. Combined with Chrysanthemi Flos (Gan Ju, 甘菊), Angelicae Sinensis Radix (Dang Gui, 当归), Rehmanniae Radix (Di Huang, 地黄), Asparagi Radix (Tian Dong, 天冬), Paeoniae Radix Alba (Bai Shao, 白芍), and Glycyrrhizae Radix et Rhizoma Preparata (Zhi Gan Cao, 炙草), it specifically treats cephalgia due to blood deficiency. For excess fire, add child's urine. Combined with Angelicae Sinensis Radix Tail (Gui Wei, 归尾), Cinnamomi Cortex (Gui Xin, 桂心), and Achyranthis Bidentatae Radix (Niu Xi, 牛膝), it treats retained dead fetus. Combined with Dipsaci Radix (Xu Duan, 续断), Rehmanniae Radix Preparata (Shu Di Huang, 熟地), Colla Corii Asini (E Jiao/Bai Jiao? Text says Bai Jiao, likely Colla Cornus or similar, keeping literal), Eucommiae Cortex (Du Zhong, 杜仲), Corni Fructus (Shan Yu Rou, 山萸), Schisandrae Fructus (Wu Wei Zi, 五味), Ginseng Radix (Ren Shen, 人参), Astragali Radix (Huang Qi, 黄芪), and Ziziphi Spinosae Semen (Suan Zao Ren, 枣仁), it treats prolonged metrorrhagia.
For wind-heat cephalgia: 1 qian of Chuanxiong and 2 qian of tea leaves, decocted in one zhong of water to five fen, taken hot before meals.
For wind-heat rushing upward causing vertigo and visual disturbances, or chest discomfort: 1 liang each of Chuanxiong and Sophorae Flos (Huai Zi, 槐子), powdered; take 3 qian per dose, mixed with tea infusion. For chest discomfort, decoct in water.
For initial wind-induced vertigo, regular or migratory headaches, excessive sweating, aversion to wind, and phlegm-fluid in the chest/diaphragm: 1 jin of Chuanxiong and 4 liang of Gastrodiae Rhizoma (Tian Ma, 天麻), powdered, honey-pilled like bullet sizes; chew one pill per dose, washed down with tea infusion.
For metrorrhagia with continuous bleeding day and night: Qian Jin Fang uses 1 liang of Chuanxiong and one large cup of clear wine, decocted to five fen, taken slowly. Sheng Hui Fang adds 2 he of fresh Rehmanniae Juice (Sheng Di Zhi, 生地汁).
[Discussion] Chuanxiong produces shoots in the third lunar month, having deeply absorbed Spring Qi, hence its warmth. By the eighth month, it begins forming tubers at the root base, harvested in the ninth and tenth months. Harvesting too late results in poor quality. This reflects the complete reception of Metal Qi, so its flavor shifts from sweet to pungent, with pungency surpassing sweetness. Qi is generated by warmth, and flavor concentrates in the root, representing Pungent-Sweet Yang; thus, its qi is strong, ascending, and floating, aligning with the Lung in humans and heaven/earth to reach the highest point. Therefore, this herb can unblock true qi, but overuse can scatter it. Reviewing medical texts, its main actions generally involve reaching Yang within Yin, or penetrating Yin within Yang, always circulating qi within the blood aspect. Hence, Hai Zang focuses on benefiting the Liver, stating it searches liver wind, tonifies liver blood, and moistens liver dryness, yet also mentions tonifying wind-deficiency. This is because the Blood organ is originally the Wind organ; only by reaching Yang within Yin can wind transformation occur, scattering cold pathogens. Understanding that non-transformation of Yang within Yin reveals that treatments for all blood disorders are based on wind-deficiency. Understanding wind-deficiency reveals the causes of liver wind, liver blood deficiency, and liver qi dryness. Why does it enter the Pericardium Qi aspect? The Liver ascends and connects with the Lung; the Lung descends and connects with the Liver. The descending aspect combines with the Foot Jueyin's same-energy Pericardium to generate blood, ultimately fulfilling the Liver's function. Human body Clear Yang ascends, Turbid Yin descends; this is the origin of qi transforming into blood. Chuanxiong reaches the vertex above and the Blood Sea below, not only grasping the pivot of ascending/descending and clear/turbid to form the source of transformation, but actually utilizing the transformation mechanism of the Wind and Blood organs for generation. Thus, it is a sacred herb for cephalgia due to blood deficiency. Regarding regulating pulses, breaking masses and old blood, nourishing new blood, and treating hematemesis, epistaxis, and hematuria, all can be treated by inferring the meaning of wind-deficiency. Only those with excessive wind pathogen cannot tolerate it. In summary, for conditions where Yang sinks into Yin or Yang cannot unblock Yin, this herb is appropriate. However, for Yin deficiency at the lower jiao failing to control Yang leading to Yang hyperactivity above, or excess Yang at the upper jiao unable to govern Yin, misusing it will only cause harm, let alone long-term use scattering true qi. (Using Chuanxiong aims to unblock Yin; it should not be used for deficient Yin. The difference between unblocking Yin and using it for deficient Yin is often overlooked by incompetent physicians.) Chuanxiong's treatment effect is best for the eyes, with cephalgia being secondary, because the Liver opens into the eyes, and among the six Qi of the human body, Wind leads. The Liver is indeed the Wind organ and also the Blood organ. Based on this wind-rising Yuan Qi, it reaches Yang within Yin and ascends. (As this classic states: "Connecting to heaven is the root of life") This allows Yin within Yang to be unblocked, and blood harmonizes with qi to transform, which is what is meant by "the eyes see when nourished by blood." (Understanding this clarifies the meaning of tonifying wind-deficiency further.) Taking Shen Li San (Kidney Filtering Powder) for wasting-thirst, for kidney qi deficiency, Magnetitum (Ci Shi, 磁石) is used as the sovereign herb, while Chuanxiong and Ophiopogonis Radix (Mai Dong, 麦冬) serve as ministers. Other herbs benefiting Yin qi and nourishing Yin blood are merely assistants. This shows that Yuan Qi is Yang within Yin, and Chuanxiong and Mai Dong as ministers adhere to the principle of penetrating Yang within Yin. Thus, for downward movement, one must enrich Yin to penetrate Yang upward. For upward conditions, any disease with excess above and deficiency below, flaming fire causing cough and vomiting, dry throat and mouth, fever, thirst, vexation, spontaneous sweating, easy sweating, or night sweats, are all contraindicated.
