Malungai is a small tree growing as high as 9 meters, with a soft and white wood and corky and gummy bark. Leaves are alternate, usually thrice pinnate, 25 to 50 centimeters long. Each compound leaf contains 3-9 very thin leaflets dispersed on a compound (3 times pinnate) stalk. The leaflets are thin, ovate to elliptic, and 1 to 2 centimeters long. Flowers are white and fragrant, 1.5 to 2 centimeters long, on spreading panicles. Pod is 15 to 30 centimeters long, pendulous, three-angled, and nine-ribbled. Seeds are three-angled, and winged on the angles.

• Malunggay leaves and pods are helpful in increasing breast milk in the breastfeeding months. One tablespoon of leaf powder provide 14% of the protein, 40% of the calcium, 23% of the iron and most of the vitamin A needs of a child aged one to three. Six tablespoons of leaf powder will provide nearly all of the woman’s daily iron and calcium needs during pregnancy and breastfeeding.
• Moringa preparations have been cited often in scientific literature as antibiotic, antiinflammatory, hypocholesterolemic and hypoglycemic. However, many of the reports are not placebo-controlled randomized clinical trials.
• Anti-Inflammatory / Anti-tumor:Anti-inflammtory and Antitumor Activities of Seeds Extracts of Malunggay—A study showed the crude ethanol extract of dried seeds inhibited the carrageenan-induced inflammation in the hind paw of mice by 85% at a dosage of 3 mg/g body weight; the mature green seeds by 77%. The crude ethanol extract also inhibited the formation of Epstein-Barr virus-early antigen (EBV-EA) induced by 12-0-tetradecanoylphorbol-13-acetate (TPA). At a dosage of 100 ?g/ml, the extract inhibited EBV-EA formation by 100% suggesting its antitumor-promoting activity.
• Ovarian Cancer: Possible Role of Moringa oleifera Lam. Root in Epithelial Ovarian Cancer: A hormonal etiology of epithelial ovarian cancer has been long suspected. Study suggests M Oleifera can interfere with hormone receptor-related and neoplastic growth-related cytokine pathways through centrally acting mechanisms.
• Asthma: Antiasthmatic activity of Moringa oleifera Lam: A clinical study: Study showed improvement in forced vital capacity, FEV1, and peak expiratory flow rate. It suggests a usefulness for MO seed kernel in patients with asthma.
• Antibiotic: 50 years ago, a study yielded Pterygospermin, a compound that readily dissociates into two molecules of benzyl isothiocyanate which has been shown to have antimicrobial properties. Unfortunately, many of the reports of antibiotic efficacy in humans were not from placebo controlled, randomized clinical trials. Recent studies have demonstrated possible efficacy against H. pylori.
• Hormonal properties / Abortifacient: Biochemical observations and histologic findings have been correlated with the anti-implantation action of aequous extracts, one possible explanation for its use as an abortifacient.
• Antiurolithiatic: Study showed lowering of stone forming constituents in the kidneys of calculogenic rats with the use of aqueous and alcoholic extracts of MO suggesting antiurolithiatic activity.
• Antimicrobial / Water Purifyiing: Study of MO seeds paste for water purification yielded a steroidal glycoside, strophantidin, a bioactive agent in the seed. The seed paste was found effective in clarification and sedimentation of inorganic and organic matter in raw water, reducing total microbial and coliform counts by 55% and 65% respectively, in 24 hours, compared to alum with 65% and 83% reduction.

Study validates scientifically claims on MO as ethnomedicine in the treatment of diabetes mellitus.
In the news
• In Leyte, extracted malunggay juice is mixed with lemonsito juice to make ice candies or cold drinks, making it more plalatble and agreeable to children who detest vegetables.
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 could increase the 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.
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 duriing the process.
• Biofuel source
• 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 of P200,000.

Malunggay ingestion is avoided in the immediate period after a family member’s death. In the superstitions-laden isms of rural Tagalog life, as a malunggay branch or twig will shed off all its leaves within a few hours of being snapped off a tree, ingesting malunggay might bring death to a relative. Avoiding its use is strongly advised during the ritual of nine days of prayers after a death.
