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.)
