RESUMEN
Objective:To observe the efficacy of Xiaoxuan Zhiyun tablet in treating cervical vertigo with syndrome of phlegm and blood stasis resistance and its effect on oxidative stress and serum levels of endothelin-1(ET-1), 5-hydroxytryptamine (5-HT), and nitric oxide (NO). Method:One hundred eighteen cervical vertigo cases were selected and randomly divided into control group (59 cases) and treatment group (59 cases) by random number table.

Both groups were treated for 3 weeks. Scores of cervical vertigo symptom and function assessment scale (ESCV) and vertigo disorder scale (DHI), blood velocity of vertebrobasilar artery, life quality and efficacy were compared between both groups.
