In Indonesia, hypertension is a condition that can lead to death through stroke and TB. Herbs have traditionally been used in Indonesia as an alternative medicine for lowering blood pressure. The leaves of Anredera cordifolia and Sonchus arvensis have been investigated for their antihypertensive potential. Based on the number of treatments, rats were randomized into groups. Each group consists of five rats. The test animals were grouping as follows: the positive control group (hypertension induction without treatment), A. cordifolia 50 mg/kg b.w. group, A. cordifolia 100 mg/kg b.w., S. arvensis 50 mg/kg b.w, S. arvensis 100 mg/kg b.w., A. cordifolia 25 mg/kg b.w + S. arvensis 25 mg/kg b.w, A. cordifolia 50 mg/kg b.w + S. arvensis 50 mg/kg b.w, and atenolol 4.5 mg/kg b.w. The rats were given 0.25 mg/kg b.w. of epinephrine intraperitoneally. The initial, after induction, and final blood pressure of the animals were measured using the CODA® noninvasive blood pressure device. All animal test groups at T60 showed a significant difference in systolic and diastolic blood pressures to initial blood pressure (T0), P < 0.05. The combination of A. cordifolia 50 mg/kg b.w and S. arvensis 50 mg/kg b.w showed the highest percent inhibition of systolic and diastolic blood pressure. The combination of A. cordifolia and S. arvensis 50-50 mg/kg b.w showed the best effect of lowering systolic and diastolic blood pressure on the pathway of inhibiting adrenergic receptors.
