Antiemetic effect of N-(2-mercaptopropionyl) glycine (MPG), vitamin C (Vit-C), grape seed proanthocyanidin (GP), and B. monnieri n-butanolic fraction (BM-ButFr). a MPG (10, 20, 30 mg/kg); b Vit-C (100, 200, 300 mg/kg); c GP (50, 100, 150 mg/kg); d BM-ButFr (5, 10, 20 mg/kg) and e their combinations on cisplatin (7 mg/kg) induced vomiting during a 24 h observation period. Each bar represents mean ± S.E.M (n = 7–8). ^* p < 0.05, ^** p < 0.01 ^*** p < 0.001 compared to cisplatin control (ANOVA followed by Tukey’s post hoc analysis)
