The stem extract showed better effectiveness against Salmonella typhi than standard Gentamicin with MIC of 10.89 and 13.88 mg/ml, respectively. (73)
• Moringa Leaves as Spice Component: Study evaluated the sensory, chemical, and microbial assessment of Moringa based spice in various formulations of nine blends of moringa-ginger-garlic. The moringa-ginger blend showed significantly low microbial count when compared to other blends. Results suggest moringa based spice products with 20% inclusion of moringa are acceptable for use in household consumable products. (74)
• Anxiolytic / Leaves: Study evaluated the anxiolytic effect of drumstick leaves using elevated plus maze (EPM) and staircase models at four doses. Results showed anxiolytic activity in both models at higher doses (200 and 400 mg/kg). (75)
• Potential Oral Anticancer Drug / Human Hepatocellular Carcinoma / Leaves: M. oleifera has been reported to have anticancer activity against various human cancer cell lines. Study evaluated leaf extracts in human hepatocellular carcinoma HepG2 cells. Results showed significant reduction (44-52%) in proliferation of HepG2 cells and A549 non-small cell lung cancer cells. Results suggest the water soluble MOL extract may be a novel and promising natural anticancer drug candidate. (76)
• Antidiarrheal / Leaves:
Study evaluated the in vivo anti-diarrheal potential of M. oleifera leaves in a castor oil-induced model. At 150 and 300 mg/kbw, the extract showed significant )p<0.01) anti-diarrheal activity compared to control. (see constituents above) (77)
• Fodder Potential of Leaf Meal: Four thesis studies characterized Moringa oleifera as a fodder for dairy cows under dry tropical conditions in Nicaragua. A study of Moringa leaf meal as a protein source in concentrates to dairy cows found no significant difference in milk production. Moringa as sole roughage resulted in higher digestibility of both CP and fiber with no effect on milk yield. Results suggest that with optimal planting density-fertiliser D2 and N3 combination, moringa leaf meal can successfully replace commercial concentrate ingredients for dairy cows. (78)
• Anticancer Potential / Breast and Colorectal Cancer Cell Lines / Leaves and Bark: Study evaluated the anti-cancer effect of Moringa oleifera leaves, bark, and seed extracts against MDA-MB-231 and HCT-8 cancer cell lines. Extracts of leaves and bark showed remarkable anticancer properties, and, surprisingly, seeds hardly exhibited activity. There was significant increase in number of apoptotic cells. GC-MS analysis yielded numerous known anti-cancer compounds viz. eugenol, isopropyl isothiocynate, D-allose, and hexadeconoic acid ethyl ester. (79)
• Moringa Tree as a Local Solution to Malnutrition: The paper presents moringa as a possible solution to malnutrition in Africa, discussing its nutritional value, its use in malnutrition prevention programs. (80)
• Implications for Climate Change Mitigation / Review: Study provides a brief overview on the multi-purpose uses of Moringa oleifera and its implication for Climate Change mitigation. MO is fast-growing and well adapted to growing in adverse climate conditions. It has a direct effect on agriculture, nutrition, health, water, environment, biodiversity and sanitation. Research has shown it potential to reduce the occurrence of water-borne disease. The tree has the capacity to mitigate the adverse effect of climate change. The rate of atmospheric absorption of carbon dioxide (CO) by MO is 20x higher than the general vegetation with great potential in storing carbon. It is an ideal crop for sustainable food production that thrives as the climate changes. MO should be promoted for nutritional consumption, medicinal functions, and climate change mitigation. (81)
• Hand Washing Potential / Leaf Powder: Study evaluated M. oleifera leaf powder as a hand washing product. Results showed 4 grams of M. oleifera leaf powder in wet and dry applications had the same effect as non-medicated soap when used for hand washing. (82)
• In Leyte, extracted
malunggay juice is mixed with lemonsito juice to make ice candies or
cold drinks, making it more palatable and agreeable to children who
Because of its high vitamin A, C, and E content, all potent antioxidants,
malunggay is a very effective in removing unstable free radicals that
is damaging to molecules and pro-aging.
• For the men: The fruit is reported to increase sperm count!
• For increasing breast milk: One rounded tablespoon of leaf powder provides
14% of protein requirements, 40% of calcium, 23% of iron, and the daily
vitamin A needs of a child aged one to three. Six rounded tablespoons
of leaf powder will provide the woman's daily iron and calcium needs
during pregnancy and breast-feeding.
• Highest Antioxidant Score: In an independent, Moringa oleifera scored the highest antioxidant content of any food yet discovered, beating the record-holding aci berry by over 50% margin, measuring over 157,000 umoles using the Oxidant Source Absorbent Capacity (ORAC) system.
Recent uses and preparation:
- Constipation: Eat one or two cups of the cooked leaves at supper time,
with plenty of water.
Wound wash: Apply crushed leaves directly to the wound, maintaining
cleanliness during the process.
• Moringa oil extracted
from the seed of the malunggay plant is now being tapped as source of
biodiesel. It is gaining preferable status over Jatropha as a source
of biofuel. All parts of the malunggay plant are used whereas Jatropha
is left with poisonous waste after oil extraction. Also, malunggay needs
only one to two years for seedling maturation compared to Jatropha's
three to five years. The math of malunggay's commercial potential is
attractive: Seeds are bought at P10 per kilo, and a hectare of malunggay
seedlings can harvest 20,000 kilos in 2 years with a potential profit
