OBJECTIVE: This clinical study monitored the effect of eating cooked Moringa oleifera leaves on the blood pressure (BP) of healthy participants in view of the perception that consumption of Moringa is associated with an increase in blood pressure, which is contradictory to the findings from the literature.
METHODS: A random sample of 41 healthy participants were enrolled in this prospective, placebo-controlled clinical study. Participants in the case study consumed 120 g of cooked M. oleifera leaves while the control group did not eat Moringa leaves. BP was measured at baseline before the meal and followed up at regular intervals over 24 hours for both groups. Baseline (T0) mean systolic blood pressure (SBP) and diastolic blood pressure (DBP) and postprandialfollow-up (T2-T24) were measured for both groups. Participants recorded their diet for a week and this led to an estimation of the total salt consumption per day.
RESULTS: A significant difference was observed between DBP at baseline and two hours postprandial (T2) for the case group (p = 0.013). Moreover, in the case group, despite high consumption of salt (7 g/d) during the week preceding the clinical study, there was a significant decrease in both the SBP and DBP. In the control group, participants with prior high consumption of salt (7 g/d) during the week had elevatedSBP and DBP.
CONCLUSIONS: These findings in human subjects indicated the lowering effect of Moringa oleifera leaves consumption on the 2 hours postprandial BP and showed a potential lowering effect on both SBP and DBP despite prior high consumption of salt (7 g/d).
