Figure 1

(a) Shows concentration-dependent inhibitory effects of the crude extract of Valeriana hardwickii (Vh.Cr) and verapamil on spontaneous and potassium-induced contractions, and (b) shows concentration-response curves of Ca++ in the absence and presence of increasing concentrations of Vh.Cr and verapamil in isolated rabbit jejunum preparations. Symbols represent mean ± S.E.M., .
