Aims: This work aimed to investigate the antihypertensive activity of Ammi visnaga. Background: The aqueous extract of Ammi visnaga has traditionally been used to treat hypertension in Morocco.

Objective: The objective of this investigation was to evaluate the effect of Ammi visnaga aqueous extract (AVAE) on arterial blood pressure, systolic blood pressure (SBP), mean blood pressure (MBP), diastolic blood pressure (DBP), and heart rate (HR) in normotensive and hypertensive rats. In addition, the effect of the aqueous extract of Ammi visnaga on vasodilatation was assessed in isolated rat aortic rings with functional endothelium pre-contracted with epinephrine EP or KCl.

Methods: AVAE was obtained, and its antihypertensive ability was pharmacologically investigated in L-NAME hypertensive and normotensive rats. The rats received oral AVAE at two selected doses of 70 and 140 mg/kg for six hours (acute experiment) and seven days (sub-chronic). Thereafter, systolic, diastolic, mean arterial blood pressure and heart rate were evaluated. Moreover, the vasorelaxant activity of AESA was performed in thoracic aortic ring rats. In addition, the mechanisms of action involved in the vasorelaxant effect were studied.

Results: AVAE lowered blood pressure only in L-Name-induced hypertensive rats. Furthermore, AVAE (0.375-1.375 mg/ml) showed a vasodilator effect in isolated aortic rats. In addition, not all of the medications used in our study were responsible for the signaling pathway. As a result, additional pharmaceuticals are required to confirm the mechanism of this signaling pathway.

Conclusion: The aqueous extract of Ammi visnaga exerts an interesting antihypertensive activity, which could be mediated through its vasorelaxant activity. The study supports its use as a medicinal plant against hypertension in Morocco.

Keywords: Ammi visnaga, hypertension, L-NAME, vasorelaxant, angiotensin-converting enzyme-2(ACE2), signaling pathway.
