Figure 4: Cumulative concentration-response curves to the 70% EtOH extract of Valeriana fauriei root and rhizome on endothelium-intact aortic rings precontracted with phenylephrine (1 μM) in the presence or absence (control) tetraethylammonium (5 mM) (a), glibenclamide (10 μM) (b), or 4-aminopyridine (1 mM) (c). Values are expressed as mean ± standard error of mean (n = 5–7)
