Figure 4From: Hypotensive effect of Gentiana floribunda is mediated through Ca++ antagonism pathway Inhibitory effect of increasing concentrations of (A) crude extract of Gentiana floribunda (Gf.Cr) and (B) verapamil on control phenylephrine (PE) peak responses in Ca ++ free medium in isolated rat aortic ring preparations. Values shown are mean ± SEM, n = 4. ** p < 0.01 and *** p < 0.001 compared to PE control peaks.Back to article page
