气味苦、温，无毒。主咳逆上气，温疟，寒热洗洗在皮肤中，妇人漏中绝子，诸
恶疮疡，金疮。煮汁饮之。
（参各家说） 当归气温，禀木气而入肝；味苦无毒，得火味而入心。其主咳逆上气者，
心主血、肝存血，血枯则肝木挟心火而刑金；当归入肝养血，入心清火，所以主之也。肝为
风，心为火，风火为阳，阳盛则为但热不寒之温疟；而肺受风火之邪，肺气怯不能为皮毛之
主，故寒热洗洗在皮肤之中；当归能令肝血足而风定，心血足而火息，则皮肤中之寒热可除
也。
心火
，血足则心火息矣。金疮无不失血，血长则金疮瘳矣。“煮汁饮之”四字，则言先圣大费苦
心，谓“中焦受气，取汁变化而赤是谓血”，当归煮汁，滋中焦之汁，与地黄作汤同义。可
知时传炒燥土炒，反涸其自然之汁，大失经旨。
气味辛、温，无毒。主中风入脑，头痛，寒痹，筋挛缓急，金疮，妇人血闭无子
陈修园曰∶芎 气温，禀春气而入肝；味辛无毒，得金味而入肺。风为阳邪，而伤于上
，风气通肝，肝经与督脉会于颠顶而为病，芎 辛温而散邪，所以主之。血少不能热肤，故
生寒而为痹；血少不能养筋，故筋结而为挛，筋纵而为缓，筋缩而为急；芎 辛温而活血，
所以主之。治金疮者，以金疮从皮肤以伤肌肉。芎 禀阳明金气，能从肌肉而达皮肤也。妇
人以血为主，血闭不通，则不生育；芎 辛温，通经而又能补血，所以治血闭无子也。
[Danggui (Radix Angelicae Sinensis)]
Taste and nature: Bitter, warm, non-toxic. Indications: Cough with rebellious Qi (Ke Ni Shang Qi), warm malaria (Wen Nüe), chills and fever shivering in the skin, uterine bleeding leading to infertility in women, various malignant sores and ulcers, and metal weapon injuries (Jin Chuang). Decoct in water and drink.
(Referencing various scholars' theories) Danggui has a warm temperature, inheriting Wood Qi to enter the Liver; its bitter taste and non-toxicity allow it to enter the Heart via Fire flavor. Its ability to treat cough with rebellious Qi is explained as follows: The Heart governs Blood, and the Liver stores Blood. When Blood is depleted, Liver Wood may carry Heart Fire to oppress Metal (Lung); Danggui enters the Liver to nourish Blood and enters the Heart to clear Fire, thus treating this condition. The Liver corresponds to Wind, and the Heart corresponds to Fire; both Wind and Fire are Yang pathogens. Excess Yang results in warm malaria characterized by heat without cold. Meanwhile, the Lung is invaded by Wind and Fire pathogens, and due to deficient Lung Qi failing to govern the skin and hair, chills and fever shiver within the skin. Danggui can enrich Liver Blood to settle Wind and enrich Heart Blood to extinguish Fire, thereby eliminating the chills and fever in the skin.
When Heart Fire subsides and Blood is sufficient, Heart Fire naturally ceases. Metal weapon injuries invariably involve blood loss; as Blood regenerates, the injury heals. The phrase "decoct in water and drink" reveals the profound intention of the ancient sages, referring to the concept that "the Middle Jiao receives Qi, extracts fluids, transforms them into red, which is called Blood." Decocting Danggui nourishes the fluids of the Middle Jiao, sharing the same principle as decocting Shengdi Huang (Rehmanniae Radix). This demonstrates that the contemporary practice of stir-frying with dry soil destroys the natural juices of the herb, greatly deviating from the original intent of the classic text.
[Xiongqiong (Rhizoma Chuanxiong)]
Taste and nature: Pungent, warm, non-toxic. Indications: Headache caused by wind-stroke invading the brain, cold-bi syndrome (Han Bi), tendon spasms or flaccidity/tightness, metal weapon injuries, and amenorrhea leading to infertility in women.
Chen Xiuyuan stated: Xiongqiong has a warm temperature, inheriting Spring Qi to enter the Liver; its pungent taste and non-toxicity allow it to enter the Lungs via Metal flavor. Wind is a Yang pathogen that tends to injure the upper body. Wind Qi connects with the Liver, and the Liver Meridian meets the Du Meridian at the vertex, causing disease. Xiongqiong is pungent and warm, capable of dispersing pathogens, thus treating this condition. Insufficient Blood cannot warm the skin, resulting in cold and bi-syndrome; insufficient Blood cannot nourish tendons, leading to tendon knotting and spasms, tendon laxity and flaccidity, and tendon contraction and tightness. Xiongqiong is pungent and warm, capable of invigorating Blood, thus treating these conditions. Regarding the treatment of metal weapon injuries, since such injuries damage muscles through the skin, Xiongqiong inherits Yangming Metal Qi, allowing it to reach from the muscles to the skin surface. Women are primarily governed by Blood; if Blood is closed and obstructed, reproduction is impossible. Xiongqiong is pungent and warm, capable of unblocking meridians and nourishing Blood, thus treating amenorrhea and infertility.
