Description
Kelin Li and colleagues present a 2026 evidence map of randomized trials testing oral traditional Chinese medicine preparations against postherpetic neuralgia. That condition is the persistent nerve pain that can follow shingles. The team searched eight databases and trial registries for trials published up to August 2025, charting how many trials exist, how well they were run, and which outcomes they measured.
The map gathered 357 trials, most of them small, with roughly 50 to 100 participants each. Pain, clinical effective rate, side effects, sleep, mood, and quality of life were the common outcomes, while recurrence and syndrome scores were rarely reported. Trial quality rated low overall on the Cochrane risk tool, and formulas differed so much in composition that favorable reports rest on shaky ground. The authors call for standardized outcomes, better syndrome differentiation, and stronger trial design.
