Moringa oleifera: Nutritional Profile, Traditional Uses, and Scientific Evidence

Moringa oleifera (drumstick tree, horseradish tree) is a fast-growing, drought-resistant tree native to the Indian subcontinent, now cultivated globally. All parts are edible; leaves are most nutrient-dense.

Nutritional Composition (per 100g fresh leaves)

• Protein: 9.4g (all essential amino acids)
• Vitamin A: 378 µg RAE (42% DV)
• Vitamin C: 51.7 mg (57% DV)
• Calcium: 185 mg (14% DV)
• Iron: 4.0 mg (22% DV)
• Potassium: 337 mg (7% DV)
• Polyphenols: quercetin, kaempferol, chlorogenic acid
• Glucosinolates → isothiocyanates (e.g., moringin)

Traditional Uses

• Leaves: malnutrition, anemia, lactation, diabetes, hypertension, inflammation, infection.
• Seeds: water purification (coagulant), oil (ben oil) for cooking/cosmetics.
• Roots/bark: caution—alkaloids (spirochin) can be toxic; not recommended.

Scientific Evidence (Human Data Limited)

• Antioxidant/anti-inflammatory: Consistent in vitro/animal; few small human trials.
• Glycemic control: Some RCTs show modest fasting glucose reduction in type 2 diabetes.
• Lipid lowering: Mixed results; may reduce LDL-C, triglycerides.
• Galactagogue: Limited RCT support for increased milk supply.
• Malnutrition: Leaf powder improves weight/height in children in resource-limited settings.

Safety

• Leaves/fruit: Generally safe as food.
• Roots/bark: Avoid—uterine stimulant, neurotoxic alkaloids.
• Drug interactions: May enhance CYP450 metabolism; caution with thyroid meds, anticoagulants, diabetes drugs.
• Pregnancy: Avoid root/bark; leaves likely safe in food amounts but insufficient data.

Moringa is a promising nutrient-dense food, not a cure-all. Use as dietary supplement within varied diet; consult provider for therapeutic use.
