芳草类药材
补血、润燥滑肠。
味甘，性温，能调和血液。味辛，性温，能发散体内寒气。味苦，性温，能助益心气以散寒。（各种血证归属于心，凡是通脉的药物，必须先补心，当归味苦性温，能助益心气。）归入心、肝、脾经。（心主生血，肝主藏血，脾主统血。）是血中的气药。治疗虚劳引起的寒热往来、咳嗽气逆上冲。（血液调和则气机下降。）治疗温疟。（厥阴肝经受邪所致）痢疾。头痛、腰痛。心腹及四肢关节的各种疼痛。（发散寒气，调和血液。）跌打损伤导致的血凝胀满。风痉无汗。（身体强直项背挺直，角弓反张称为痉，无汗称为刚痉，有汗称为柔痉，当归味辛能疏散风邪，性温能调和血液，产后也有发生痉病的，是因为失血过多无法滋养筋脉，适宜使用十全大补汤。）痿痹症瘕。（筋骨松弛无力，足部不能支撑身体称为痿，风寒湿邪客居于肌肉血脉称为痹。）痘疹、痈疽疮疡。冲脉病变。气逆里急。带脉病变。腹痛腹胀。腰部溶溶然如同坐在水中。（冲脉起于肾下，出于气街穴，挟脐上行，至胸中，上达鼻咽部，渗灌诸阳经，灌注诸经脉，下行入足，渗灌三阴经，灌注诸络脉，为十二经脉之海，主管血液；带脉横向环绕腰部，如束带一般，总约约束诸条经脉。）以及妇人各种不足之证，一切血证。阴虚而阳气无所依附者。滋润肠胃。润泽皮肤。祛除瘀血，生成新血。温中养营。活血舒筋。排脓止痛。（血液调和则疼痛停止。）使气血各有所归属，因此得名。（血滞能疏通，血虚能补益，血枯能滋润，血乱能安抚，大概因为它的辛温能行气分，使气机调畅而血液调和。李东垣说：头止血而上行，身养血而居中守持，尾破血而下流，全草活血而全面统治。雷敩、张元素并云：头破血，李时珍说：治上部病用头，治中部病用身，治下部病用尾，全面统治则用全草。雷敩著有《雷公炮炙论》，李时珍说：这个雷公是刘宋时的雷敩，不是黄帝时的雷公。）极善于滑利肠道。腹泻者禁用。（当归为君药，白芍为臣药，地黄为佐药，川芎为使药，名为四物汤，是治疗血证的总方剂，血虚者佐用人参、黄芪，血热者佐用黄芩、栀子、黄连。王好古说：血属阴，必须得阳气才能生血，气虚血弱的人，应当使用人参、黄芪，取阳气旺盛而生阴血的义理。）四川产的力道刚猛善于攻逐。陕西产的力道柔和善于补益。以陕西产的头圆尾多、肥润气香、内部洁白不油腻的为优良品种，名为马尾当归。尾部粗硬干枯的，名为藁本头当归。只适宜用于发散。宜用酒制。治疗吐血。宜用醋炒。畏菖蒲、海藻、生姜。恶湿面。（当归和酒服用，治疗难产胎儿死亡不出。）

Category of Fragrant Herbs
Nourishes blood, moistens dryness, and lubricates the intestines for unblocking bowels.
Sweet and warm, harmonizes blood. Acrid and warm, disperses internal cold. Bitter and warm, assists Heart Qi to scatter cold. (All blood disorders belong to the Heart; for any herb that unblocks collaterals, one must first tonify the Heart; Dang Gui is bitter and warm, assisting the Heart.) Enters the Heart, Liver, and Spleen meridians. (The Heart generates blood, the Liver stores blood, the Spleen controls blood.) It is the Qi herb within the Blood category. Treats deficiency consumption with alternating chills and fever, coughing with rebellious Qi. (When blood is harmonized, Qi descends.) Treats warm malaria. (Pathogen of the Jueyin Liver meridian.) Dysentery. Headache, lower back pain. Various pains in the heart, abdomen, limbs, and joints. (Scatters cold and harmonizes blood.) Traumatic injury causing blood stasis and distension. Wind-induced spasm without sweat. (Body stiffness and neck straightness, opisthotonos is termed spasm; without sweat is rigid spasm, with sweat is flaccid spasm. Dang Gui is acrid to disperse wind and warm to harmonize blood. Postpartum spasm may also occur due to blood loss failing to nourish tendons, suitable for use of Shiquan Dabu Decoction.) Atrophy, bi-syndrome, and zhijia masses. (Muscle and bone laxity with inability of feet to bear weight is termed atrophy; wind-cold-dampness lodging in muscles and blood vessels is termed bi-syndrome.) Smallpox, carbuncles, sores, and ulcers. Diseases of the Chong Mai (Penetrating Vessel). Rebellious Qi and interior urgency. Diseases of the Dai Mai (Girdle Vessel). Abdominal pain and fullness. Lower back feeling loose and watery, as if sitting in water. (The Chong Mai originates below the kidney, emerges at Qicheng point, ascends alongside the umbilicus to the chest, reaches the nasopharynx, permeates the Yang meridians, irrigates the twelve regular meridians, descends into the feet, permeates the Yin meridians, and irrigates the collateral vessels, serving as the Sea of the Twelve Meridians, governing blood; the Dai Mai encircles the waist horizontally like a belt, summarizing and constraining all meridians.) Also treats various deficiencies in women, all blood disorders. Yin deficiency where Yang has no anchor. Moistens the intestines. Nourishes the skin. Removes stasis and generates new blood. Warms the middle and nourishes Ying Qi. Invigorates blood and relaxes tendons. Expels pus and stops pain. (When blood is harmonized, pain ceases.) Causes Qi and Blood to return to their proper locations, hence the name. (Stagnant blood can be unblocked, deficient blood can be tonified, withered blood can be moistened, chaotic blood can be pacified; generally its acrid-warm nature moves Qi, ensuring Qi is regulated and Blood is harmonized. Li Dongyuan said: The head stops bleeding and moves upward, the body nourishes blood and stays central, the tail breaks stasis and flows downward, the whole root invigorates blood and governs comprehensively. Lei Xiao and Zhang Yuansu both stated: The head breaks stasis. Li Shizhen said: Use the head for upper body diseases, the body for middle body diseases, the tail for lower body diseases, and the whole root for comprehensive treatment. Lei Xiao authored *Lei Gong's Processing of Medicinals*; Li Shizhen noted: This Lei Xiao was from the Liu Song dynasty, not the Lei Gong of the Yellow Emperor era.) Extremely good at lubricating the intestines. Contraindicated in diarrhea. (Dang Gui is the Sovereign herb, Bai Shao is the Minister herb, Di Huang is the Assistant herb, Xiong Qiao is the Envoy herb, named Siwu Tang [Four Substance Decoction], the general formula for treating blood disorders. For blood deficiency, add Ren Shen and Huang Qi; for blood heat, add Huang Qin, Zhi Zi, and Lian Lian. Wang Haogu said: Blood belongs to Yin, requiring Yang to generate it. For those with Qi deficiency and weak blood, Ren Shen and Huang Qi should be used, taking the meaning of vigorous Yang generating Yin.) Sichuan-produced varieties have strong potency and are good for attacking. Shaanxi-produced varieties have mild potency and are good for tonifying. The best quality comes from Shaanxi, characterized by round heads, many tails, plumpness, moisture, fragrant aroma, and white interiors without oiliness, named Mawei Dang Gui. Those with thick, hard, and dry tails are named Gaoben Tou Dang Gui, suitable only for dispersing. Should be processed with wine. To treat hematemesis, stir-fry with vinegar. Incompatible with Chang Pu, Hai Zao, and Sheng Jiang. Detested by wet flour. (Dang Gui taken with wine treats dystocia with fetal death retained inside.)
