Pattern Overview
Wind-Cold Binding the Exterior is a pattern in eczema, characterized by cold-induced mast cell degranulation, winter exacerbation, urticarial lesions, and intense itching. The core pathogenesis is invasion of Wind-Cold pathogens into the exterior, causing cold-induced mast cell degranulation and skin lesions.
Key Symptoms and Differentiation Points
| Differentiation Dimension | Manifestations |
|---|---|
| Primary Symptoms | Urticarial lesions, intense itching, worse with cold exposure, winter exacerbation |
| Associated Symptoms | Chills, no sweating, nasal congestion, headache |
| Tongue and Pulse | Pale red tongue with thin white coating, floating and tense pulse |
| Pathogenesis | Wind-Cold pathogens binding the exterior |
| Etiology | Cold exposure, winter season, constitutional Wind-Cold, cold urticaria |
Acupuncture Point Prescription
| Point | Location | Function |
|---|---|---|
| Fengchi (GB20) | Depression below the occipital bone, between the sternocleidomastoid and trapezius | Disperses Wind and releases the exterior |
| Hegu (LI4) | Dorsum of the hand, between the 1st and 2nd metacarpals | Disperses Wind and releases the exterior |
| Lieque (LU7) | Above the wrist, on the radial side, in the depression between the tendons | Diffuses the Lung and disperses Wind-Cold |
| Xuehai (SP10) | On the medial thigh, 2 cun above the patella | Cools Blood and stops itching |
| Quchi (LI11) | Lateral end of the elbow crease | Clears Heat and stops itching |
Clinical Recommendation: Filament needle, reducing method; moxibustion may be added to disperse Cold.

Western Mechanism Reference
Cold-induced mast cell degranulation and histamine release, with cold urticaria or eczema aggravated by cold. Wind-Cold Binding the Exterior corresponds to cold-induced eczema or urticaria, where cold exposure activates TRPA1/TRPM8 channels inducing mast cell degranulation and histamine release.
