血属于阴性的物质。其性质类似于大地上的水泉。本性是静止的，但运行起来则表现为阳的特性。因此，血是“阴中之阳”，这就像坎卦（☵）中蕴含火象一样。因为外为阴、内为阳，所以血能够运行；若纯为阴而无阳，则无法运行。血不能运行就会凝滞，凝滞就会导致经络不通。《内经》说：足阳明胃经，通常气血都很旺盛。又说：足阳明胃经，能化生气血。手太阳小肠经，斜行联络于目系。足太阳膀胱经，起始于目内眦。这两条经脉都是多血少气。血病且运行不畅时，由于血量多，容易凝滞。《素问·灵兰秘典论》说：脾胃是仓廪之官，五味由此化生。五味过度摄入会损伤胃，胃受损则导致血病，这就是由“五味”产生的邪气，是从本源产生的。又说：小肠是受盛之官，负责化物并排出糟粕。遇到寒邪则会阻碍其化物功能。又说：膀胱是州都之官，负责贮藏津液。遇到风邪则会使其贮藏散失。一阻一散，血也会随之生病，这就是由“风寒”产生的邪气，是从末端产生的。凡是邪气胜复，血病且运行不畅，运行不畅逐渐停滞，停滞就容易凝滞，凝滞后病症才会从外部显现出来。这是因为小肠经斜络于目系，膀胱经起于目内眦的缘故。所以病症表现为眼眶周围发青，像被物体击伤的样子。病情重的，白睛也会发红或出现瘀血斑。病情轻的，或者形成斑点。然而不痛不痒，也没有流泪、眼屎多、羞明涩痛等症状，这叫做“血为邪胜，凝而不行之病”。此病初起时，大体上与伤风证相似，一二日后才明显显现出此病的特征。用川芎行经散主治。用消凝大丸子主治。眼睛疼痛的，再加用当归养荣汤主治。这样就能使凝滞消散，气血运行，邪气消除，疾病痊愈，血液恢复常态，哪有不好的道理呢？

Blood is a Yin substance. Its nature resembles the springs and streams on earth. It is inherently static, but its movement manifests as Yang. Thus, blood is "Yin within which lies Yang," resembling the image of fire contained within the Kan trigram (☵). Because it is Yin on the outside and Yang on the inside, it can move; if it were purely Yin without Yang, it would not move. If blood does not move, it stagnates; if it stagnates, the meridians become obstructed. The Classics state: "The Foot-Yangming Stomach Meridian usually possesses abundant Qi and Blood." It also states: "The Foot-Yangming Stomach Meridian generates Qi and Blood." The Hand-Taiyang Small Intestine Meridian slants and connects to the eye system. The Foot-Taiyang Bladder Meridian originates at the inner canthus of the eye. Both these meridians are characterized by abundant Blood and deficient Qi. When Blood pathology occurs with impaired movement, due to the abundance of Blood, it is prone to coagulation. The *Suwen: Linglan Midian Lun* states: "The Spleen and Stomach are the officials of the granaries, from which the Five Flavors emerge." Excessive intake of the Five Flavors damages the Stomach; when the Stomach is damaged, Blood pathology ensues. This is the pathogenic factor generated from the "Five Flavors," arising from the root. It further states: "The Small Intestine is the official of reception and transformation, from which processed substances emerge." Encountering Cold obstructs its transformative function. It also states: "The Bladder is the official of the capital, where body fluids are stored." Encountering Wind causes its storage to scatter. One obstruction and one dispersion cause Blood pathology as well; this is the pathogenic factor generated from "Wind and Cold," arising from the branches. Whenever pathogenic factors prevail, Blood pathology leads to impaired movement. Impaired movement gradually leads to stasis; stasis easily leads to coagulation. Once coagulated, the disease manifests externally. This is because the Small Intestine Meridian slants to connect to the eye system, and the Bladder Meridian originates at the inner canthus. Therefore, the disease presents as bluish-black discoloration around the eyes, resembling an injury from a blunt object. In severe cases, the sclera also becomes red or streaked with blood. In mild cases, spots may form. However, there is no pain or itching, nor symptoms such as tearing, excessive discharge, or photophobia and grittiness. This is called the disease of "Blood being overcome by pathogens, coagulating and failing to move." At the initial stage, this disease largely resembles wind-cold exterior syndrome, becoming distinct after one or two days. It is primarily treated with *Chuanxiong Xingjing San* (Cinnamon Twig and Ligusticum Decoction for Moving Meridians) or *Xiaoning Da Wanzi* (Great Pill for Dissolving Coagulation). If eye pain is present, *Danggui Yangrong Tang* (Angelica Decoction for Nourishing the Ying) is added. By doing so, coagulation dissipates, stasis moves, pathogens are eliminated, and the disease is cured, restoring Blood to its normal state. How could recovery not be achieved?
*Chuanxiong Xingjing San* (Treats bluish-black discoloration in the eye resembling an injury; in severe cases, the sclera appears streaked with blood.)
Jiegeng (Platycodonis Radix, 5 qian), Fuling (Poria, 7 qian), Qianghuo (Notopterygii Rhizoma et Radix), Manjingzi (Viticis Semen), Baizhi (Angelicae Dahuricae Radix), Fangfeng (Saposhnikoviae Radix), Jingjie (Schizonepetae Spica), Boheye (Menthae Haplocalycis Herba), Duhuo (Angelicae Pubescentis Radix, each 4 qian), Chaihu (Bupleuri Radix), Chuanxiong (Ligustici Chuanxiong Rhizoma), Gancao (Glycyrrhizae Radix et Rhizoma, honey-fried, 3 qian), Danggui (Angelicae Sinensis Radix), Zhike (Aurantii Fructus, each 6 qian), Honghua (Carthami Flos, 2 qian).
Grind all into powder. Take 3 qian per dose. Add 2 zhong of water, decoct until 1 zhong remains. Strain and take while hot, after meals.
In the above formula, Zhike and Gancao harmonize Stomach Qi and serve as the Sovereign (Jun) herbs. Baizhi, Fangfeng, Jingjie, Bohe, and Duhuo dispel Wind pathogens and ascend Stomach Qi, serving as the Minister (Chen) herbs. Chuanxiong, Danggui, and Honghua move stagnant Blood. Chaihu resolves Qi stagnation. Fuling promotes diuresis and drains dampness, serving as the Assistant (Zuo) herbs. Qianghuo and Manjingzi guide the action into the Taiyang Meridian. Jiegeng benefits the Five Zang Organs, serving as the Envoy (Shi) herb. Thus, the Stomach Meridian is regulated, and the Small Intestine and Bladder benefit. Pathogens are expelled, and coagulation dissolves. For cases presenting with Heat, *Xiaoning Da Wanzi* is primarily used.
*Xiaoning Da Wanzi* (Treats the same conditions as above. Also treats cases with discharge, tearing, and gritty sensation.)
Chuanxiong, Dangguiwei (Tail of Angelicae Sinensis Radix), Jiegeng, Gancao (honey-fried), Lianqiao (Forsythiae Fructus), Jiahujuhua (Chrysanthemi Flos, each 7 qian), Fangfeng, Jingjie, Qianghuo, Subohhe (Menthae Haplocalycis Herba), Gaoben (Ligustici Wallichii Rhizoma et Radix, each 5 qian), Huashi (Talcum), Shigao (Gypsum Fibrosum), Shanzhizi (Gardeniae Fructus), Baizhu (Atractylodis Macrocephalae Rhizoma), Huangqin (Scutellariae Radix, each 1 liang).
First, grind Huashi and Shigao separately. Grind the remaining herbs into fine powder and mix evenly. Use refined honey to make pills. Each batch weighs 1 liang, divided into eight pills. Take one or two pills per dose, chewed down with tea water.
The above formula consists of herbs that dissolve coagulation and stasis. Chuanxiong and Danggui are the Sovereign herbs, treating Blood disorders and harmonizing Blood. Qianghuo, Fangfeng, Jingjie, Gaoben, Bohe, and Jiegeng are the Minister herbs, treating Wind and dispersing pathogens, guiding the action into the Hand and Foot Taiyang Meridians. Baizhu, Gancao, Huashi, and Shigao are the Assistant herbs, tonifying Stomach deficiency, unblocking Qi stagnation, and venting Heat from the Foot-Yangming Stomach Meridian. Huangqin, Shanzhi, Lianqiao, and Juhua are the Envoy herbs, clearing Heat and relieving irritability. These are suitable for conditions where pathogenic factors overact, counter-acting, and where Wind-Heat is uncontrolled.
