INTRODUCTION: We previously demonstrated the hemostatic effects of notoginseng using a rat bleeding model. Yun-Nan-Bai-Yao is a proprietary product for external use in China to treat bleeding but the hemostatic effects have not been proven. This study was conducted to compare the hemostatic effects of notoginseng to that of Yun-Nan- Bai-Yao and placebo control. METHODS: Rats (n = 37) were randomized into 3 groups and their tails were transected 5mm from the tip in this blinded investigation. Group 1 received placebo (wheat flour, n = 17), group 2 received notoginseng (n = 10) and group 3 received the Yun-Nan-Bai-Yao (n = 10). The total bleeding time was determined and compared among groups. RESULTS: Beeding time in minutes was 29.7% and 22.3% lower in the notoginseng and Yun-Nan-Bai-Yao groups than the placebo group (p < 0.001 and p < 0.001, respectively). No significant difference was found between the two active groups (p = 0.418). CONCLUSIONS: When applied externally, both notoginseng and Yun-Nan-Bai-Yao provide appreciable hemostatic effects compared to placebo.
