Trauma as a pathogen
Physical injury from external forces such as falls, blows, cuts, burns, or strain that disrupts Qi and Blood circulation, leading to Blood Stasis with characteristic pain, swelling, and bruising. Classified as a miscellaneous (non-external, non-internal) pathogenic factor in TCM.

Liver
The Liver stores Blood and governs sinews/tendons—any trauma affecting circulation or musculoskeletal system impacts Liver function.
Spleen
The Spleen governs muscles and holds Blood in vessels. Trauma can weaken Spleen function and impair tissue nourishment.
Kidneys
The Kidneys govern bones and produce Marrow. Bone injuries and fractures directly impact Kidney function.
Heart
The Heart houses the Shen (Spirit). Severe trauma can scatter the Shen, causing anxiety, fear, and emotional disturbance.

Overview
Trauma (外伤, Wài Shāng) is classified in Traditional Chinese Medicine as a "miscellaneous" or "neither external nor internal" pathogenic factor—meaning it doesn't originate from climatic influences like Wind or Cold, nor from emotional disturbances. Instead, trauma results from direct physical forces acting on the body: falls, blows, cuts, burns, animal bites, or strain from improper lifting.
In TCM, the key consequence of trauma is the disruption of Qi (vital energy) and Blood circulation. When external force damages tissues, the smooth flow of Qi and Blood becomes obstructed, leading to what's called "Blood Stasis" (瘀血, Yū Xuè)—essentially blood that has pooled or stagnated rather than circulating properly. This explains the familiar signs of injury: localized pain (especially fixed, stabbing pain that worsens with pressure), swelling, and bruising. The ancient principle "where there is pain, there is no free flow" (不通则痛) perfectly captures this concept.
TCM divides trauma into external damage (外损) affecting skin, muscles, tendons, and bones, and internal injury (内伤) where the impact disrupts organ function and Qi-Blood harmony. The severity ranges from minor soft tissue injuries to serious conditions involving bone fractures, joint dislocations, or even organ damage. Treatment focuses on restoring circulation, dispersing stagnant blood, reducing swelling, and promoting tissue healing.
Historical Context
TCM has a rich tradition of treating trauma, developed significantly through martial arts practices and battlefield medicine. The Tang Dynasty classic Wai Tai Mi Yao (752 CE) established the fundamental distinction between external damage and internal injury that remains used today.
The specialized field of Die Da (跌打, "falls and blows") medicine evolved particularly through Shaolin Temple and other martial arts traditions, where practitioners developed sophisticated treatments for combat injuries. The Shaolin Zhen Chuan Shang Ke Mi Fang (Shaolin True Transmission of Trauma Secret Formulas) represents this martial medicine tradition.
The Yi Zong Jin Jian (Golden Mirror of Medicine, 1742) consolidated and systematized trauma treatment, emphasizing that all traumatic injuries must be understood through the lens of Blood—whether stagnant or lost. This blood-focused approach to trauma remains central to TCM orthopedics and traumatology today.
Defining Characteristics
Direct Physical Impact
外力作用Unlike other pathogens, trauma results from direct mechanical force acting on the body—falls, blows, cuts, burns, or strain. The injury location corresponds to where the force was applied.
Blood Stasis Formation
瘀血形成Trauma invariably causes Blood Stasis as the impact damages vessels and obstructs circulation. The TCM saying 'new injuries damage Qi, old injuries enter the Blood' describes how acute trauma affects Qi flow first, then becomes Blood Stasis if unresolved.
Qi and Blood Disruption
气血不和External force disrupts the harmonious flow of both Qi and Blood. Qi stagnation causes distending pain, while Blood stasis causes fixed stabbing pain. Both must be addressed for complete healing.
Staged Progression
分期变化Trauma follows predictable stages: acute inflammation (first week), tissue repair (weeks 2-6), and remodeling (6+ weeks). TCM treatment adapts to each stage with different therapeutic approaches.
Potential for Shen Disturbance
神志受扰Severe trauma can scatter the Shen (Spirit), causing anxiety, fear, dissociation, or feeling disconnected from one's body. This psychological impact is recognized and treated alongside physical injuries.
Entry Routes
Trauma enters the body through direct physical impact on the body's surface and tissues. Unlike climatic pathogens that may enter through specific orifices, trauma acts directly at the site of injury:
- Direct impact: Falls, blows, collisions affecting skin, muscles, and bones
- Penetrating injuries: Cuts, stab wounds, and punctures from sharp objects
- Thermal damage: Burns and scalds affecting the skin and deeper tissues
- Strain: Improper lifting, overexertion, or repetitive stress on muscles and tendons
Progression Pattern
Body Layers Affected
Xue (Blood)Trauma follows a characteristic progression pattern:
- Immediate Impact (Hours): External force causes tissue damage. Qi is disrupted first, causing immediate pain. Blood vessels may rupture, beginning localized bleeding.
- Acute Stage (Days 1-7): Blood Stasis forms as extravasated blood accumulates. Inflammation peaks with swelling, heat, and pain. If severe, Blood loss can lead to Qi collapse.
- Subacute Stage (Weeks 2-6): Body begins clearing stagnant blood and repairing tissue. Swelling reduces, bruise color changes from purple to yellow-green. Pain decreases but stiffness may persist.
- Chronic Stage (if unresolved): Incompletely treated injuries become 'old injuries' (陈伤) with residual Blood Stasis. Characterized by persistent dull pain, stiffness worse in cold/damp weather, and possible adhesion formation.
- Constitutional Impact: Severe or repeated trauma can weaken Qi and Blood, requiring tonification. Liver and Kidney deficiency may develop, affecting tendon and bone health long-term.
Clinical Relevance
Trauma remains highly relevant in modern clinical practice. TCM approaches are particularly valuable for:
- Sports injuries: Sprains, strains, contusions where quick recovery is essential
- Post-surgical recovery: Reducing adhesions and promoting healing after operations
- Chronic pain from old injuries: 'Old injuries' (陈伤) that never fully resolved respond well to blood-invigorating treatment
- Whiplash and soft tissue injuries: Where Western medicine offers limited options beyond pain management
- Fracture healing support: Accelerating bone repair alongside conventional treatment
TCM treatment typically combines internal herbal formulas with external applications (liniments, plasters), acupuncture, and Tui Na massage for comprehensive care.
Common Manifestations
Localized Pain
Fixed, stabbing pain at the injury site that worsens with pressure—the hallmark of Blood Stasis. Pain may be severe and constant in acute injuries.
Swelling and Bruising
Visible swelling, discoloration (purple, blue, or dark red), and hematoma formation as blood accumulates outside the vessels in damaged tissues.
Restricted Movement
Limited range of motion due to pain, swelling, or structural damage to joints, tendons, or muscles. Stiffness typically accompanies stagnation.
Heat and Inflammation
Local warmth, redness, and inflammatory response at the injury site as the body attempts to heal damaged tissue.
Deformity
In cases of fractures or joint dislocations, visible abnormality in the shape or alignment of the affected area.
Emotional Disturbance
Severe trauma can scatter the Shen (Spirit), causing anxiety, fear, restlessness, poor concentration, or feeling 'not fully present' in the body.
Internal Bleeding Signs
In severe internal trauma: dark stools, vomiting blood, abdominal distension, dizziness, or fainting from blood loss.
Tongue Manifestations
Tongue changes in trauma vary with severity and stage:
- Acute trauma: Tongue may show purple spots or patches, indicating Blood Stasis. In severe cases, the entire tongue may appear dark or purple.
- With significant blood loss: Pale tongue indicating Blood deficiency
- Chronic stasis: Purple or dark tongue with distended sublingual veins
- With infection/Heat: Red tongue with yellow coating
- With Cold: Purple-blue tongue, especially at edges
Pulse Manifestations
Pulse findings vary with the nature and severity of trauma:
- Acute trauma with stasis: Choppy (sè) or hesitant pulse, reflecting obstructed Blood flow
- With significant pain: Wiry (xián) pulse from Qi constraint due to pain
- Severe blood loss: Thin, weak, or thready pulse; possibly faint in shock
- With Heat/infection: Rapid pulse added to above qualities
- Chronic Blood Stasis: Choppy and deep pulse, especially at the inch position relevant to injury site
Common Pathogen Combinations
Trauma with Dampness
Combined with Dampness as a pathogenWhen injuries occur in damp conditions or healing is complicated by Dampness, symptoms include persistent swelling that is soft and pitting, heaviness in the affected area, slow healing, and possible weeping wounds. Recovery is prolonged and requires herbs that drain Dampness alongside blood-movers.
Trauma with Cold
Combined with Cold as a pathogenCold exposure during or after injury causes blood to congeal more severely. Pain is worse with cold and better with warmth. The affected area may feel cold to touch, and circulation is further impaired. Warming herbs like cinnamon are added to treatment.
Trauma with Heat
Combined with Fear as a pathogenWhen trauma becomes infected or involves burns, Heat combines with Blood Stasis. Signs include marked redness, warmth, possible fever, pus formation, and rapid pulse. Treatment must clear Heat and toxins while moving blood.
Differentiation from Similar Pathogens
Trauma vs. Bi Syndrome (Painful Obstruction): Both cause pain and limited movement. Trauma has clear history of injury, localized to impact site, with bruising. Bi Syndrome is caused by Wind-Cold-Damp, often affects multiple joints, worsens with weather changes, and lacks bruising.
Trauma vs. Internal Blood Stasis: Trauma-induced stasis has external cause and specific injury location. Internal Blood Stasis develops gradually from emotional stress, cold exposure, or Qi deficiency without external injury, and often has more diffuse or migratory symptoms.
Trauma vs. Overwork (Lao Sun): Overwork causes gradual strain from repetitive activities; trauma is sudden and acute. Overwork primarily causes Qi deficiency with secondary stasis; trauma primarily causes stasis with possible Qi-Blood loss.
Treatment Principles
The fundamental treatment principles for trauma in TCM follow a staged approach:
- Acute Stage (First 1-2 weeks): Focus on invigorating blood circulation and dispersing stasis (活血化瘀, Huó Xuè Huà Yū), reducing swelling, and relieving pain. Strong blood-moving herbs are used.
- Middle Stage (2-6 weeks): Continue moving blood but add herbs that harmonize and connect tendons and bones, promote tissue regeneration, and strengthen the injured area.
- Recovery Stage (6+ weeks): Nourish Qi and Blood, strengthen Liver and Kidneys (which govern tendons and bones), and consolidate healing. Tonic herbs replace the stronger blood-movers.
General principles include: regulate Qi to help Blood flow (行气活血), warm the channels if Cold is present, clear Heat if infection develops, and calm the Shen if emotional disturbance accompanies severe trauma.
