Xue Fu Zhu Yu Tang (血府逐瘀汤), known in English as Blood Mansion Dispel Stasis Decoction, is a classical TCM formula by Wang Qing-ren for dispelling Blood stasis in the chest (upper jiao). It is particularly indicated for chest pain, hypochondriac pain, insomnia, palpitations, irritability, and various conditions with Blood stasis in the upper body, including coronary heart disease and angina. In modern clinical practice, Xue Fu Zhu Yu Tang is widely used for cardiovascular and emotional disorders involving Blood stasis with Qi stagnation in the chest. By powerfully moving Blood, regulating Qi, and nourishing Blood, it effectively resolves stasis in the upper jiao while addressing the underlying deficiency.

I. Origins and History

1. Source of the Formula

Xuefu Zhuyu Tang originates from the *Yilin Gaicuo* (Correction of Errors in the Forest of Medicine), written by the renowned Qing dynasty physician Wang Qingren. Wang Qingren was an exceptionally innovative physician in the history of ancient Chinese medicine; he placed great importance on human anatomy, and through personal observation and practice, developed a deeper understanding and correction of the traditional theory of the internal organs. The *Yilin Gaicuo* embodies his lifetime of clinical experience and deep reflection on medicine, and Xuefu Zhuyu Tang is one of its classical formulas.

2. Historical Background and Significance

In Wang Qingren's era, although traditional medicine had accumulated some understanding and treatment methods for blood-stasis disorders, certain limitations still remained. Through observation and treatment of a large number of patients with blood-stasis disorders, Wang Qingren discovered many complex conditions caused by blood stasis and summarised corresponding treatment methods. The creation of Xuefu Zhuyu Tang provided a systematic and effective formula for treating blood-stasis disorders, enriching the theory and practice of activating blood and resolving stasis in Chinese medicine, and exerting a profound influence on later generations' treatment of blood-stasis-related diseases.

II. Herb Composition (Sovereign, Minister, Assistant, Envoy)

1. Chief Herbs — Taoren and Honghua

Taoren (Peach Kernel) is bitter and sweet in flavour, neutral in nature, and enters the heart, liver, and large intestine channels. It has the actions of activating blood and dispelling stasis, and moistening the intestines to unblock bowel movements. Taoren is rich in oil, with a moist, descending quality, able to break blood and move stagnation while moistening dryness, and is excellent for treating a variety of disorders caused by blood-stasis obstruction. Honghua (Safflower) is acrid in flavour, warm in nature, and enters the heart and liver channels. It activates blood and unblocks the menses, dispersing stasis and relieving pain. Honghua is red in colour and excels at moving through the blood aspect, making it an essential herb for activating blood and resolving stasis. Taoren and Honghua are used together, mutually reinforcing each other and strengthening the power to activate blood and resolve stasis, playing a key therapeutic role in targeting the main pathomechanism of internal blood-stasis obstruction, and are therefore both chief herbs.

2. Deputy Herbs — Danggui and Chuanxiong

Danggui (Angelica Root) is sweet and acrid in flavour, warm in nature, and enters the liver, heart, and spleen channels. It tonifies and activates blood, regulates menstruation and relieves pain, and moistens the intestines to unblock bowel movements. Danggui both tonifies blood and activates blood — tonifying within movement and movement within tonification — allowing blood stasis to be expelled while new blood is generated. Chuanxiong (Szechuan Lovage Rhizome) is acrid in flavour, warm in nature, and enters the liver, gallbladder, and pericardium channels. It activates blood and moves qi, dispelling wind and relieving pain. Chuanxiong is acrid and fragrant, dispersing and warming to unblock the blood vessels, earning it the description "the qi herb within the blood"; it assists the chief herbs' power to activate blood and resolve stasis while also moving qi and relieving pain, and the two are therefore deputy herbs.

3. Assistant Herbs — Shengdihuang, Chishao, Zhiqiao, and Jiegeng

Shengdihuang (Raw Rehmannia Root) is sweet and bitter in flavour, cold in nature, and enters the heart, liver, and kidney channels. It clears heat and cools the blood, nourishing yin and generating fluids. In the formula, it prevents the blood-activating, stasis-resolving herbs from being too warming and drying, which could damage yin, playing a role in clearing heat and nourishing yin, and restraining the warming, drying nature of the chief and deputy herbs. Chishao (Red Peony Root) is bitter in flavour, slightly cold in nature, and enters the liver channel. It clears heat and cools the blood, dispersing stasis and relieving pain, assisting the chief and deputy herbs in strengthening the action of activating blood and resolving stasis. Zhiqiao (Bitter Orange) is bitter, acrid, and sour in flavour, warm in nature, and enters the spleen and stomach channels. It regulates qi and relieves middle-burner distension, moving stagnation and reducing bloating. Jiegeng (Platycodon Root) is bitter and acrid in flavour, neutral in nature, and enters the lung channel. It diffuses the lung, benefits the throat, resolves phlegm, and expels pus. Zhiqiao and Jiegeng, one descending and one ascending, broaden the chest and move qi, so that when qi moves, blood moves, helping to disperse blood stasis; the two are together the assistant herbs.

4. Envoy Herbs — Niuxi and Gancao

Niuxi (Achyranthes Root) is bitter, sweet, and sour in flavour, neutral in nature, and enters the liver and kidney channels. It expels stasis and unblocks the menses, tonifies the liver and kidney, strengthens the sinews and bones, promotes urination to unblock painful urinary dribbling, and directs blood downward. It both activates blood and dispels stasis, and directs stagnant blood downward so that it does not disturb the upper body, while also tonifying the liver and kidney and harmonising the other herbs, and is therefore an envoy herb. Gancao (Licorice) is sweet in flavour, neutral in nature, and enters the heart, lung, spleen, and stomach channels. It tonifies the spleen and boosts qi, moistens the lung to stop coughing, clears heat and resolves toxicity, and harmonises the actions of the other herbs. In the formula, Gancao harmonises the properties of the various herbs, making the whole formula's combination more coordinated, and thus plays the role of envoy herb.

III. Pathomechanism, Actions, and Indications

1. Pathomechanism

The pathomechanism targeted by Xuefu Zhuyu Tang is mainly internal blood-stasis obstruction. Under the influence of various internal and external factors — such as emotional disharmony, external trauma, or cold pathogens congealing and obstructing — the body's qi and blood movement becomes sluggish, and blood stagnates within the vessels, forming blood stasis. Internal blood-stasis obstruction can lead to a variety of pathological changes, affecting the normal function of the organs and channels, and in turn giving rise to various disorders.

2. Actions

Xuefu Zhuyu Tang has the actions of activating blood, resolving stasis, moving qi, and relieving pain. Through the synergistic action of Taoren, Honghua, Danggui, Chuanxiong, and other blood-activating, stasis-resolving herbs in the formula, blood stasis can be dispersed and blood circulation improved. At the same time, the use of qi-regulating herbs such as Zhiqiao and Jiegeng allows qi to move so that blood moves, strengthening the effect of activating blood and resolving stasis. Niuxi directs blood downward, giving the stasis an outlet and preventing it from disturbing the upper body. Together, the whole formula achieves the effect of activating blood, resolving stasis, moving qi, and relieving pain.

3. Indications

Xuefu Zhuyu Tang mainly treats the pattern of blood stasis in the chest. Symptoms include chest pain and headache of long duration that do not resolve, pain that is fixed in location and stabbing in character, or persistent hiccup, or choking upon drinking water, dry retching, or internal heat with a stifling sensation, or palpitations and fearful throbbing, insomnia with excessive dreaming, irritability and a tendency to anger, evening tidal fever, dark lips or dark discoloration around the eyes, a dark red tongue body, or petechiae and stasis spots on the tongue, and a choppy or wiry, tight pulse. These symptoms all arise from blood stasis internally obstructing the chest, with sluggish movement of qi and blood.

IV. Formula Analysis

1. Activating Blood, Resolving Stasis, and Unblocking the Vessels

In the formula, blood-activating, stasis-resolving herbs such as Taoren, Honghua, Danggui, Chuanxiong, and Chishao are combined together, targeting the pathomechanism of internal blood-stasis obstruction and acting directly on the blood vessels, eliminating blood stasis and allowing the vessels to be unblocked. Once the blood stasis is removed, qi and blood can move normally, and the function of the organs and channels can also be restored to normal.

2. Moving Qi to Relieve Pain and Regulating the Qi Mechanism

Zhiqiao and Jiegeng, one ascending and one descending, broaden the chest and move qi. Qi is the commander of blood; when qi moves, blood moves. By regulating the qi mechanism, this helps disperse blood stasis while also relieving pain symptoms caused by blood-stasis obstruction. A smoothly regulated qi mechanism, with orderly movement of qi and blood, is of great significance for improving the condition.

3. Directing Blood Downward to Balance Qi and Blood

Niuxi has the action of directing blood downward. Internal blood-stasis obstruction readily causes qi and blood to rebel upward, giving rise to symptoms such as headache and dizziness. Niuxi can guide the rebellious qi and blood downward, bringing qi and blood toward balance and avoiding the various discomforts caused by qi and blood disturbing the upper body.

4. Clearing Heat and Nourishing Yin to Prevent Damage to Righteous Qi

Shengdihuang clears heat and cools the blood, nourishing yin and generating fluids. Blood-activating, stasis-resolving herbs are mostly acrid and warming in nature, and can readily consume yin blood. The presence of Shengdihuang prevents these herbs from being too warming and drying and damaging yin, allowing the whole formula to activate blood and resolve stasis while also attending to the body's yin fluid, combining attack with supplementation and avoiding damage to righteous qi.

5. Harmonising the Herbs for Synergistic Effect

Gancao harmonises the properties of the various herbs, allowing them to work together more coordinately and strengthening the formula's overall efficacy. At the same time, Gancao also moderates the toxicity and irritating quality of the herbs, ensuring the safety of the treatment.

V. Comparison with Related Formulas

1. Comparison with Taohong Siwu Tang

Taohong Siwu Tang is composed of Taoren, Honghua, Danggui, Chuanxiong, Baishao (White Peony Root), and Shudihuang (Prepared Rehmannia Root), and has the action of nourishing blood and activating blood. Compared with Xuefu Zhuyu Tang, both formulas share the four blood-activating, stasis-resolving herbs Taoren, Honghua, Danggui, and Chuanxiong. However, Taohong Siwu Tang emphasises nourishing blood, with Shudihuang and Baishao nourishing yin and blood as the main focus, and is mainly used for blood deficiency with concurrent blood stasis. Xuefu Zhuyu Tang, on the other hand, has a stronger action of activating blood and resolving stasis, and includes qi-moving, pain-relieving herbs, placing greater emphasis on treating the pattern of qi stagnation and blood stasis caused by internal blood-stasis obstruction, and is particularly suited to blood stasis in the chest.

2. Comparison with Gexia Zhuyu Tang

Gexia Zhuyu Tang mainly treats the pattern of blood stasis obstructing the subdiaphragmatic region, and is composed of Taoren, Honghua, Danggui, Chuanxiong, Chishao, Mudanpi (Tree Peony Bark), Wuyao (Lindera Root), Yanhusuo (Corydalis Rhizome), Gancao, Xiangfu (Cyperus Rhizome), Zhiqiao, and Wulingzhi (Flying Squirrel Droppings). Compared with Xuefu Zhuyu Tang, both formulas share the actions of activating blood, resolving stasis, moving qi, and relieving pain. However, Gexia Zhuyu Tang emphasises treating blood stasis in the subdiaphragmatic region, such as lower abdominal pain and dysmenorrhoea. Xuefu Zhuyu Tang mainly targets blood stasis in the chest, with symptoms presenting mainly as chest pain and headache.

3. Comparison with Tongqiao Huoxue Tang

Tongqiao Huoxue Tang mainly treats the pattern of stasis obstructing the head and face, and is composed of Chishao, Chuanxiong, Taoren, Honghua, Laocong (Aged Scallion), Xianjiang (Fresh Ginger), Hongzao (Red Dates), and Shexiang (Musk). This formula focuses on unblocking the orifices and activating blood, mainly treating symptoms such as headache, hair loss, and a dusky, purplish complexion caused by blood-stasis obstruction of the head and face. Xuefu Zhuyu Tang can also treat headache, but places greater emphasis on the overall pathomechanism of blood stasis in the chest, with a broader scope of application not limited to blood-stasis disorders of the head and face.

VI. Clinical Applications

1. Cardiovascular Disease

Xuefu Zhuyu Tang can be used to treat cardiovascular diseases such as coronary heart disease and angina. Patients with coronary heart disease often experience blood stasis obstructing the heart vessels, leading to symptoms such as chest pain and tightness. Xuefu Zhuyu Tang's actions of activating blood, resolving stasis, moving qi, and relieving pain can improve cardiac blood circulation, relieve angina symptoms, and reduce the occurrence of myocardial ischaemia. Clinical research shows that combining Xuefu Zhuyu Tang with Western medication for coronary heart disease can improve treatment outcomes, reduce the frequency of angina attacks, and improve ECG findings.

2. Neurological Disorders

For neurological disorders such as migraine and insufficient cerebral blood supply, Xuefu Zhuyu Tang also has a certain therapeutic effect. Migraine is often caused by blood stasis obstructing the channels with sluggish qi-blood movement. Xuefu Zhuyu Tang can unblock the channels, activate blood, and resolve stasis, relieving headache symptoms. In insufficient cerebral blood supply, sluggish cerebral blood circulation gives rise to symptoms such as dizziness and headache. Xuefu Zhuyu Tang can improve cerebral blood circulation and increase cerebral blood flow, relieving discomfort such as dizziness and headache.

3. Gynaecological Disorders

In the gynaecological field, Xuefu Zhuyu Tang is commonly used to treat dysmenorrhoea, amenorrhoea, and irregular menstruation. Dysmenorrhoea is often caused by blood stasis obstructing the uterus with sluggish qi-blood movement. Xuefu Zhuyu Tang can activate blood, resolve stasis, move qi, and relieve pain, effectively relieving dysmenorrhoea symptoms. If amenorrhoea or irregular menstruation is caused by internal blood-stasis obstruction, Xuefu Zhuyu Tang can regulate the menstrual cycle, promote the expulsion of menstrual blood, and restore normal menstrual function.

4. Psychiatric Disorders

Some psychiatric disorders, such as insomnia and depression, if differentiated as internal blood-stasis obstruction, may also be treated with Xuefu Zhuyu Tang. Internal blood-stasis obstruction can cause the heart-spirit to lack nourishment, giving rise to symptoms such as insomnia with excessive dreaming and depressed mood. Xuefu Zhuyu Tang activates blood and resolves stasis, helping to improve qi-blood movement and regulate the heart-spirit, thereby relieving insomnia symptoms and improving depressive mood.

VII. Clinical Modifications
