Pattern Overview
Yin Deficiency with Yang Hyperactivity is a chronic pattern in trigeminal neuralgia, characterized by increased nerve excitability, burning pain, worse at night, dry mouth, and irritability. The core pathogenesis is Yin deficiency failing to control Yang, leading to Yang hyperactivity, nerve hyperexcitability, and central sensitization.
Key Symptoms and Differentiation Points

|---|---|
| Primary Symptoms | Burning pain, worse at night, dry mouth, irritability |
| Associated Symptoms | Heat in palms and soles, night sweats, dizziness, tinnitus |
| Tongue and Pulse | Red tongue with little coating, thready and rapid pulse |
| Pathogenesis | Yin deficiency with Yang hyperactivity causing nerve hyperexcitability |
| Etiology | Chronic trigeminal neuralgia, aging, constitutional Yin deficiency, prolonged illness |
Acupuncture Point Prescription

Western Mechanism Reference
Increased nerve excitability with Na+ channel abnormal expression, nerve hyperexcitability, and central sensitization. Yin Deficiency with Yang Hyperactivity corresponds to chronic trigeminal neuralgia with nerve hyperexcitability, where Na+ channel abnormal expression and central sensitization contribute to persistent burning pain.
