First Report of Eurycoma longifolia Jack Root Extract Causing Relaxation of Aortic Rings in Rats

Figure 2

Representative tracing of dose-dependent relaxations (B-C) induced by cumulative additions of DCM (0.1–3 mg/mL) in PE-precontracted (A-B) aortic ring. Doses of DCM were only added once the relaxant response had stabilised. At the end of the dose-response experiment, the ring was allowed to equilibrate before adding PE (D) again to the tissue chamber to test for viability of the ring. -axis: compressed passage of time.
