Blood Stasis in TCM: Understanding Stagnant Blood and Its Impact on Health
Learn about Blood Stasis (Xue Yu) in Traditional Chinese Medicine — what causes stagnant Blood, how to recognize its signs, and practical ways to restore healthy circulation.
What is Blood Stasis?
Blood Stasis (血瘀, Xue Yu) is one of the most important pathological concepts in Traditional Chinese Medicine. It describes a condition where Blood no longer flows freely through the vessels and meridians, becoming sluggish, congested, or trapped in a specific area.
In TCM theory, Blood must circulate smoothly to nourish the organs, tissues, and spirit. When Blood stagnates, it not only fails to nourish — it actively creates problems. Stagnant Blood is considered both a cause and a result of disease: it can be generated by trauma, emotional distress, or Cold, and once present, it produces pain, lumps, and discoloration.
What Causes Blood Stasis?
1. Qi Stagnation
Qi is the commander of Blood — “when Qi moves, Blood moves; when Qi stops, Blood stops.” Emotional stress, frustration, and suppressed feelings cause Liver Qi to stagnate, which in turn slows Blood flow. This is the most common cause of Blood Stasis in modern life.
2. Cold
Cold has a congealing, contracting nature. Exposure to cold temperatures, eating excessive cold foods, or living in damp, cold environments can cause Blood to thicken and slow down — much like water freezing into ice.
3. Trauma
Physical injury, surgery, falls, and sprains can directly damage the vessels and meridians, trapping Blood in the affected area. This is why bruises and swelling persist long after the initial trauma.
4. Qi Deficiency
When Qi is too weak to propel Blood forward, circulation slows. This is common in elderly individuals or those recovering from chronic illness.
5. Heat
Paradoxically, excessive Heat can also cause Blood Stasis. Heat dries up Body Fluids, making Blood more viscous and concentrated. It can also “cook” the Blood, causing it to congeal.
Signs and Symptoms of Blood Stasis
Pain
The hallmark of Blood Stasis is fixed, stabbing, or boring pain that is worse with pressure and does not move around. Unlike Qi stagnation pain (which tends to wander), Blood Stasis pain stays in one place.
Physical Signs
- Purple or dark spots on the lips, tongue, or skin
- Varicose veins and spider veins
- Bruises that appear easily or take a long time to fade
- Lumps and masses — both external (like lipomas) and internal (like fibroids or cysts)
- Dark clots during menstruation
Tongue Diagnosis
- Purple or purplish tongue body
- Purple spots or macules on the tongue
- Engorged purple sublingual veins
Pulse
- Choppy (se) or wiry (xian) pulse

How TCM Addresses Blood Stasis
1. Herbal Medicine
Herbs that invigorate Blood and remove stasis are central to treatment:
- Dan Shen (Salvia) — perhaps the most widely used Blood-invigorating herb, especially for Heart and chest issues
- Chuan Xiong (Sichuan Lovage) — moves both Qi and Blood, especially in the head and upper body
- Tao Ren (Peach Kernel) — breaks up stubborn Blood stasis
- Hong Hua (Safflower) — invigorates Blood circulation
- Ru Xiang (Frankincense) — moves Blood and relieves pain, especially in joints
2. Acupuncture
Key acupuncture points for Blood Stasis include:
- SP10 (Xue Hai — Sea of Blood): Regulates Blood and removes stasis
- BL17 (Ge Shu): The influential point for Blood
- LV3 (Tai Chong): Moves Liver Qi and Blood
3. Movement
Gentle, consistent exercise is one of the simplest ways to prevent and treat Blood Stasis. Tai Chi, Qigong, and even daily walking help maintain healthy circulation.
4. Dietary Support
| Food | Action |
|---|---|
| Black fungus (wood ear mushroom) | Invigorates Blood |
| Hawthorn berry | Moves Blood, aids digestion |
| Ginger | Warms and promotes circulation |
| Turmeric | Invigorates Blood, reduces inflammation |
| Vinegar | Softens masses, moves Blood |
