Methods Databases of CBM, CNKI, VIP and Wanfang were searched from the time of the establishment till May 2010 and randomized controlled trials (RCT) of gastrodine injection compared with other positive drugs for VBI were included. Quality evaluation and meta-analysis by using RevMan 5.0 were performed. Results A total of 8 grade-C RCTs including 648 cases were gathered. The results of meta-analysis showed that the difference of excellent and effective rates between danshen injection and gastrodine injection for VBI were significant: RR=1.63, 95%CI (1.37, 1.95) and RR=1.21, 95%CI (1.12, 1.30). Conclusion Based on current evidence, compared with danshen injection, gastrodine injection is better and safer for VBI.
