The levels of selected elements in Hibiscus sabdariffa calyces and Lippia asperifolia leaves were determined for possible effects on human blood pressure. The aim was to determine the level of selected elements in each species and comparing the iron level, while investigation of their possible effects on human blood pressure was also highlighted. Ten samples each from Hibiscus sabdariffa calyces and Lippia asperifolia leaves were collected from four areas of Zanzibar Island (Bububu and Mtoni for Hibiscus sabdariffa, and Kombeni and Fuoni for Lippia asperifolia). The X-ray fluorescence method of analysis was used using EDXRF equipment at TAEC, Arusha, Tanzania. The summary of the analyzed elements is; Ca in L. asperifolia ˃ Ca in H. sabdariffa; Fe in L. asperifolia ˃ Fe in H. sabdariffa; P in L. asperifolia ˃ Fe in H. sabdariffa; K in L. asperifolia ˂ K in H. sabdariffa. Human blood pressures (fifty participants) were investigated before and after providing each participant with 300 mL of the extracted juice. The participants’ blood pressures were recorded at 30-minute intervals after oral intake of the juice, which was done using clinically validated blood pressure arm monitor. The results obtained show that, the provision of juices caused participants’ Systolic blood pressures (SBPs) as well their Diastolic Blood Pressures (DBPs) to drop remarkably. Following data analysis, the use of juices made from H. sabdariffa calyces and L. asperifolia leaves could be a good source of raising the level human hemoglobin (high iron content present in these plant species). Comparatively, L. asperifolia (due to high iron content present) could be a good and preferred source for increasing human blood level than H. sabdariffa. However, both plant species have negative relationship with SBPs and DBPs. Nevertheless, people are obliged to seek medical advice before their frequent and long consumption of these plant materials, this due to their significant impact on human blood pressure.
