Figure 1: Effect of gum acacia as control (C), nimesulide alone (N), paracetamol alone (P), and nimesulide and paracetamol combination (N + P) on formalin-induced pain in rats. Each point represents mean pain score ± SEM (n = 6). *P < 0.05 and **P < 0.01, compared with control treatment (Wilcoxon– Mann– Whitney test).
