Figure 3

Effects of H. bonariensis extract on isolated Wistar rat atria. Injection of the extract into the organ tank caused a significant progressive decrease in atrial contraction frequency from 0.2 mg/ml. In contrast, contraction amplitudes were increased from the same concentration and then decreased from 0.4 mg/ml. n = 4. ; ; ; and (two-way ANOVA+ Dunnett’s test).
