From: Mechanisms underlying the antihypertensive properties of Urtica dioica
Typical tracing showing inhibitory effect of a increasing concentrations of the crude extract of U. dioica (Ud.Cr) on the initial peak formation of phenylephrine in Ca2+-free medium. b The combined effect of Ud.Cr, its ethyl acetate (Ud.EtAc), nHexane (Ud.nHex), chloroform (Ud.Chl), and aqueous (Ud.Aq) fractions, and c the effect of verapamil on initial peak formation of PE in isolated rabbit aorta preparations, in Ca2+-free medium. Values shown are mean ± SEM (6–7)
