Abstract: This review examines medicinal plants, which have been reported to have hypotensive or antihypertensive effects. It pays particular attention but not totally restricted to plants whose antihypertensive effects have been scientifically validated. The main aim of the review is to piece together information on this subject, so as to raise more awareness, prevent duplication of efforts and possibly bring more attention to medicinal plants as a veritable source of antihypertensive drug. As the review ended, it was possible to conclude that, a lot of efforts are still needed not only in the validation of the plants but also in the areas of identifying the active principles in these medicinal plants and the conduct of clinical trials in humans.
