Pattern Overview
Wind-Heat Attacking the Collaterals is a pattern in acute Bell’s palsy, characterized by facial nerve inflammation (HSV-1 reactivation), sudden facial paralysis, facial heat pain, fever, and sore throat. The core pathogenesis is invasion of Wind-Heat pathogens into the facial collaterals, causing viral-induced neuroinflammation, nerve damage, and facial paralysis.
Key Symptoms and Differentiation Points
| Differentiation Dimension | Manifestations |
|---|---|
| Primary Symptoms | Sudden facial paralysis, facial heat pain, ear pain, fever |
| Associated Symptoms | Sore throat, thirst, red eyes, irritability |
| Tongue and Pulse | Red tongue with thin yellow coating, floating and rapid pulse |
| Pathogenesis | Wind-Heat pathogens invading the facial collaterals |
| Etiology | Viral infection (HSV-1), upper respiratory infection, Wind-Heat invasion |
Acupuncture Point Prescription
| Point | Location | Function |
|---|---|---|
| Fengchi (GB20) | Depression below the occipital bone, between the sternocleidomastoid and trapezius | Disperses Wind-Heat and clears the head |
| Hegu (LI4) | Dorsum of the hand, between the 1st and 2nd metacarpals | Disperses Wind and unblocks collaterals |
| Quchi (LI11) | Lateral end of the elbow crease | Clears Heat and detoxifies |
| Dicang (ST4) | About 0.4 cun lateral to the corner of the mouth | Treats deviation of the mouth |
| Jiache (ST6) | In the depression on the lower border of the zygomatic arch, about 1 cun anterior to the angle of the mandible | Treats facial paralysis |
| Yifeng (TE17) | Behind the ear, in the depression between the mastoid process and the mandible | Treats ear pain and facial paralysis |
Clinical Recommendation: Filament needle, even method; during the acute phase, use gentle technique. May combine with Dazhui pricking to enhance Heat clearing.

Western Mechanism Reference
Facial nerve inflammation following HSV-1 reactivation, with viral-induced neuroinflammation and nerve damage. Wind-Heat Attacking the Collaterals corresponds to Bell’s palsy associated with HSV-1 reactivation, where viral replication and neuroinflammation contribute to facial nerve damage.
