Moringa oleifera leaves are rich in proteins, vitamin A, minerals, essential amino acids, antioxidants, and flavonoids, as well as isothiocyanates. But no human clinical trial has been done to evaluate its efficacy in reducing malnutrition.
A study conducted to determine the nutritional value of different moringa species in leaves reveals high variations in protein content and micro and macro nutrients. Moringa oleifera leaves were clearly rich of protein but no information is available on its bioavailability, amino acid sequence and anti-nutritional elements(1).
A trial was done on using Moringa oleifera leaf powder (MLP) in infants as fortified food supplement on its effect on hemoglobin and growth parameters after 4 months of intervention. However, hemoglobin and growth parameter s did not improve significantly(2).
There has been few safety studies conducted in humans and concluded that it is safe at recommended doses(3).
In mice, moringa leaves protects against arsenic induced poisoning(4).
Moringa oleifera Leaf Petroleum Ether Extract Inhibits Lipogenesis(5)
It also exhibits antihyperlipidemic activity in rabbits(6).
Moringa leaves also has some anticancer properties but more research is needed(7).
Additionally, moringa leaves, pods, seeds and oil have immunomodulatory, antinflammatory, antimicrobial, antihyperglycemic and antioxidant properties(8).
