Tree grows as high as 9 m, with a soft and white wood and corky and gummy bark. Root
has the taste of horseradish. Each compound leaf contains 3-9 very thin
leaflets dispersed on a compound (3 times pinnate) stalk. Flowers are white
and fragrant, producing long, pendulous, 9-ribbed pods, with 3-angled winged
seeds.
Distribution
• Introduced from Malaya or some other
part of tropical Asia in prehistoric times.
• Grown throughout the Philippines in settled areas as a backyard
vegetable and as a border plant.
• Drought resistant and grows in practically
all kinds of well-drained soils. Conserves water by shedding leaves
during dry season.
Propagation
• Propagation by seeds and stem cuttings.
• Mature malunggay cuttings should be 2 cm or more in diameter and not less than 80 cm (30 inches) in length. Mature cuttings are preferred as they sprout earlier and grow faster.
• The only pests known to attack malunggay are mites of the Tetranychus spp.

• In West Bengal, India, roots
taken by women, esp prostitutes, for permanent contraception (Studies
have shown total inactivation or suppression of the reproductive system).
Studies
• 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.
• Antiinflammatory
/ 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. <Abstract:http://www.stii.dost.gov.ph/pjsweb/data/antitumor_of_malunggay.htm>
• 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. source
• 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.
• Antipyretic / Wound Healing:
Study of the ethanolic and ethyl acetate extracts of MO showed significant
antipyretic activity in rats; the ethyl acetate extract of dried leaves
showed significant wound healing on rat wound models.
• Analgeic: Previous
studies have shown analgesic activity from the leaves of MO. This study
on the alcoholic extract of MO seeds showed potent analgesic activity
comparable to that of aspirin dose of 25 mg/kg BW.
• Hepatoprotective / Antioxidant:
Study concluded that the alcoholic extracts of MO produced significant
hepatoprotective and antioxidant activity, the aqueous extracts of the
fruit less than the alcoholic extract.
• Anthelmintic: In a comparative study of the anthelmintic activity of M oleifera and V negundo against Indian earthworm Pheritima posthuma, dose-dependent activity was observed with M oleifera showing more activity than V negundo.
• Comparison with Atenolol: Study comparing the effects of M oleifera with atenolol in adrenaline-induced rats on serum cholesterol, triglycerides, glucose level, heart and body weight showed the M oleifera leave extract made significant changes in each cardiovascular parameter.
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.

the ethanol extract produced hypotensive, bradycardic and negative inotropic
effects in experimental animals.
• The bark may cause violent uterine contractions that can be
fatal. Chronic high-dose use may cause liver and kidney dysfunctions.
• In frequent or large doses, Interior flesh of the plant can
cause toxic nerve paralysis from the alkaloid spirochin. source
Supertitions
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.
