Moringa oleifera (MO) phytochemicals and therapeutic properties improve hyperglycemia and treat type 2 diabetes. Thus, this study examined the effects of MO leaf capsules on blood glucose management in type 2 diabetic mellitus (T2DM) and hypertension and their safety. A prospective placebo-controlled experiment randomly assigned 24 patients to receive 3g and 6g of MO leaf capsules twice a day or a placebo for three months. Pre- and post-study lab and clinical outcomes were assessed. The placebo control group and 3g MO leaf showed a minor change, whereas 6g and control placebo showed a considerable drop in examined features. MO usage was safe. In T2DM patients, MO leaves lowered blood pressure, requiring further study. MO leaves may help T2DM patients manage blood pressure and blood sugar, according to the study. MO's therapeutic components need more research.
