Effect of P. quadrangularis (Pq) on mean arterial pressure (MAP) administrated intravenously in normotensive rats.

Blood Pressure	Control	10 mg/kg Pq	20 mg/kg Pq	40 mg/kg Pq	80 mg/kg Pq
MAP, mmHg	128 ± 4	103 ± 2	94 ± 8 **	82 ± 6 ***	55 ± 3 ***

Values are mean ± standard error of the mean of 5 experiments in mmHg. ** p < 0.01 and *** p < 0.001 vs. control.
