Blood Stasis
Description
Blood Stasis is a TCM pattern where blood circulation stagnates, leading to stabbing, fixed pain, dark spots, varicose veins, dark menstruation with clots, a purplish tongue, and a choppy (rough, irregular) pulse. This pattern can result from trauma, surgery, prolonged Qi stagnation, cold constricting blood vessels, or heat thickening the blood. Blood stasis is a major pathogenic factor in many chronic conditions such as atherosclerosis, ischemic heart disease, stroke, endometriosis, fibromyalgia, chronic pain, cirrhosis, and malignant tumors. Chronic blood stasis leads to tissue hypoxia, fibrosis, and eventually organ dysfunction.
Clinical features
Pain
Stabbing, sharp, knife-like pain, fixed (non-migratory), worse at night, with pressure, with cold, sometimes better with movement, often at a specific location (hypochondrium, lower abdomen, joints, chest). Skin/tissues: Purplish-blue or dark spots (ecchymosis), varicose veins, telangiectasias (spider veins), dark circles under eyes, couperose, cold hands and feet with cold stasis. Menstrual (women): Dark, purple menstruation, thick, dark clots, heavy menstruation or sharp, stabbing pain before or during menstruation, endometriosis, fibroids. Head/face: Dark lips, purplish tongue, dark eyelids, dull eyes, migraine with sharp, fixed pain, dizziness, memory loss. Extremities: Numbness, tingling, cold limbs (especially at night), acrocyanosis (blue fingers/toes), non-healing ulcers, leg ulcers. Cardiovascular: Angina pectoris (stabbing chest pain), palpitations, shortness of breath, leg swelling (edema), varicose veins. Emotion/mind: Irritability, depression, restlessness, insomnia, forgetfulness, in severe cases confusion (with cerebral stasis). Tongue: Purple (entire tongue or purple spots/dots), possibly dark-purple, blue-purple, swollen tongue body, widened sublingual veins, possibly red spots with heat-stasis. Pulse: Choppy (Choppy, Ru), irregular, rough, stabbing, possibly wiry (Xian) with pain, deep (Chen) with deep stasis, possibly irregular (Jie, Dai) with severe stasis or arrhythmias.
π Etiology
Primary causes
1) Trauma: surgery, fracture, bruise, laceration (acute blood loss, local hematoma). 2) Prolonged Qi stagnation: Qi cannot propel Blood β blood stasis (Liver Qi stagnation β liver blood stasis). 3) Cold: cold constricts blood vessels β stasis, cold limbs, bruises, varicose veins. 4) Heat: heat dries and thickens blood β stasis, red tongue with red spots, dark clots. 5) Dampness/phlegm: dampness can block blood vessels β stasis. 6) Blood loss (postpartum, trauma): clotting, hematoma. 7) Prolonged immobilization (bed rest, cast). 8) Smoking, alcohol abuse, diabetes, hypertension, dyslipidemia. Risk factors: Atherosclerosis, ischemic heart disease, stroke (CVA), peripheral vascular disease, diabetes, hypertension, smoking, obesity, sedentary lifestyle, trauma, surgery, endometriosis, fibromyalgia, malignant tumors.
π¬ Pathology mechanism
Blood stasis β (1) Blockage of blood vessels β stabbing, fixed pain, dark spots. (2) Insufficient tissue oxygenation β hypoxia, tissue damage, fibrosis, organ dysfunction. (3) Coagulation activation β hypercoagulability, thrombosis, embolism. (4) Inflammatory response β increased cytokine production, endothelial dysfunction, atherosclerosis. Modern level: increased blood viscosity, increased fibrinogen, increased platelet aggregation, increased red blood cell aggregation, decreased blood flow (ischemia), hypoxia, oxidative stress, endothelial dysfunction, increased thromboxane A2, decreased nitric oxide (NO), increased PAI-1, decreased fibrinolytic activity, hypercoagulability (elevated D-dimer, elevated fibrinogen, decreased antithrombin III).
βοΈ Differential diagnosis
Blood Stasis vs Qi Stagnation
Qi stagnation has distending, dull, migratory pain; blood stasis has stabbing, fixed pain. Blood Stasis vs Cold Stasis: Cold stasis has cold limbs, cold pain (better with warmth), pale-blue tongue. Blood Stasis vs Heat Stasis: Heat stasis has red tongue with red spots, thirst, dark urine, worse with heat. Blood Stasis vs Dampness Stasis: Dampness stasis has edema, bloating, heavy sensation, swollen tongue with teeth marks.
π Prognosis & complications
Prognosis
Chronic course (years to decades). Improvement with consistent treatment (herbs, acupuncture, cupping, diet, lifestyle). Without treatment: progressive decline to more severe stasis, organ ischemia, fibrosis, organ failure, thrombosis, embolism. Complications: Atherosclerosis, ischemic heart disease (angina pectoris, myocardial infarction), stroke (CVA, TIA), peripheral vascular disease (intermittent claudication, leg ulcers, gangrene), deep vein thrombosis (DVT), pulmonary embolism, portal hypertension (cirrhosis), endometriosis, uterine fibroids, chronic pain syndromes (fibromyalgia), renal insufficiency, erectile dysfunction, malignant tumors (angiogenesis, metastasis). Red flags: Severe angina pectoris (chest pain radiating to arm/jaw), shortness of breath at rest, syncope, unilateral weakness, facial droop, speech difficulties, acute abdominal pain, hemiparesis β acute myocardial infarction or stroke, immediate emergency referral.

Western understanding:
Blood stasis correlates with cardiovascular disease, stroke recovery, chronic pain, and menstrual irregularities. Characterized by fixed stabbing pain, purple tongue, and a choppy pulse.
Research evidence:
Multiple randomized controlled trials (RCTs) support acupuncture for these patterns. Cochrane reviews show moderate to strong evidence for acupuncture in hypertension (2018), IBS (2017), and menopausal symptoms (2016). Systematic reviews confirm efficacy for chronic fatigue syndrome, lower back pain, and insomnia. Evidence quality varies by condition. Large-scale RCTs recommended for specific pattern differentiation.
π©Ί Treatment strategy

Gynecological stasis (endometriosis): Ge Xia Zhu Yu Tang (Drive Out Stasis Below the Diaphragm Decoction). Post-traumatic stasis: Shen Tong Zhu Yu Tang (Drive Out Stasis from Painful Body Decoction). Angina pectoris: Dan Shen Pian (Salvia miltiorrhiza tablet) or Guan Xin Su He Wan (Coronary Heart Relief Pill). Acupuncture: LI4 (Hegu) - disperse (activates blood), LR3 (Taichong) - disperse, SP10 (Xuehai) - disperse (blood point), BL17 (Geshu) - disperse (blood point), BL18 (Ganshu) - disperse, ST36 (Zusanli) - disperse, CV6 (Qihai) - disperse, LV14 (Qimen) - disperse (blood stasis in hypochondrium), PC6 (Neiguan) - disperse (angina pectoris), TE5 (Waiguan) - disperse. Phase 2 (maintenance, prevention, chronic stasis): Dan Shen Pian (Salvia tablet) or Xue Fu Zhu Yu Tang (lower dose). Cupping: Moving cupping on back (BL17, BL18, BL20, BL43) and along Gallbladder meridian. Wet cupping (blood letting) only by experienced practitioner. Moxa: Only with cold stasis (warmth dilates blood vessels), moxa on BL17, ST36, CV6, LI4. Not with heat stasis. Frequency: Acute (pain): 2-3x/week; Maintenance: 1x/week. Duration: 4-8 weeks, then reassess; chronic cases: 3-6 months or longer.
π₯ Diet & lifestyle
Diet (recommended): Blood-activating, stasis-resolving, warm, spicy foods: garlic, onion, ginger, turmeric, cayenne pepper, black pepper, cinnamon, fennel, rosemary, thyme, sage, basil, dark leafy greens (spinach, kale, chard), beets, pomegranate, cherries, grapes, blueberries, blackberries, eggplant, red wine (limited, 1 glass/day), dark chocolate (70-85%, 1-2 pieces/day), red clover, hawthorn berries, ginkgo biloba, fish (salmon, mackerel, sardines, anchovies - omega-3 fatty acids), nuts (walnuts, almonds), seeds (flaxseed, chia seeds), olive oil. Diet (avoid): Cold, raw, cooling foods (constrict blood vessels): raw vegetables (salads), ice, cold drinks, cucumber, watermelon, melon, banana, citrus fruits (orange, tangerine, grapefruit), mint, dairy (milk, yogurt, cheese), sugar (increases viscosity), processed foods, trans fats (margarine, fast food), excessive alcohol. Lifestyle: Regular exercise (walking, jogging, swimming, cycling, yoga, tai chi, qigong) - essential for blood circulation! Avoid prolonged sitting/standing, take breaks to move, warm baths, sauna, massage, cupping, acupuncture, adequate hydration (drink warm water, herbal tea).
π‘οΈ Prevention
Primary prevention
Active lifestyle, regular exercise (minimum 30 minutes walking or other moderate activity daily), healthy diet (rich in fiber, omega-3 fatty acids, antioxidants, low in saturated fats, sugar, processed foods), avoid smoking and excessive alcohol, maintain healthy weight (BMI 18.5-24.9), control blood pressure, cholesterol, blood glucose. Secondary prevention: For at-risk individuals (hypertension, diabetes, dyslipidemia, smoking history, family history of cardiovascular disease, obesity, sedentary lifestyle) regular assessment of stasis status via tongue and pulse diagnosis, regular acupuncture maintenance sessions (1x/month), herbal maintenance (Dan Shen Pian 1-2x/week), daily low-dose aspirin (only under medical supervision). Screening: Annual screening: blood pressure, blood glucose (fasting glucose, HbA1c), lipid profile (LDL, HDL, triglycerides), homocysteine, CRP, coagulation parameters (fibrinogen, D-dimer). For at-risk patients: ECG, echocardiogram, ankle-brachial index (ABI), carotid intima-media thickness (CIMT).
