Moringa oleifera is a plant whose fruits, roots and leaves have been advocated for traditional medicinal uses. The physico-chemical analysis shows that, Moringa contains more dietary polyunsaturated fatty acids (PUFA) than saturated fatty acids (SFA). The consumption of an experimental diet enriched with Moringa oleifera extracts lowered blood pressure in spontaneously hypertensive rats (SHR), but not in normotensive Wistar-Kyoto (WKY) rats as compared to rats fed an unsupplemented control diet. Anti-CD3-stimulated T-cell proliferation was diminished in both strains of rats fed the Moringa oleifera...
