Moringa is All We Need To Be in Good Health
Imagine a tree in your backyard that will meet all your nutritional needs, take care of you medicinally, and purify your water for you. This tree actually exists. For centuries, the natives of northern India and many parts of Africa have known of the many benefits of Moringa oleifera. Its uses are as unique as the names it is known by, such as clarifier tree, horseradish tree and drumstick tree (referring to the large drumstick shaped pods) and in East Africa it is called “mother’s best friend”. Virtually every part of the tree can be used. Native only to the foothills of the Himalayas, it is now widely cultivated in Africa, Central and South America, Sri Lanka, India, Malaysia and the Philippines. This tree, though little known in the Western world, is nutritional dynamite. There are literally hundreds of uses for this tree.
The immature pods are the most valued and widely used of all the tree parts. The pods are extremely nutritious, containing all the essential amino acids along with many vitamins and other nutrients. The immature pod can be eaten raw or prepared like green peas or green beans, while the mature pods are usually fried and possess a peanut-like flavor. The pods also yield 38 – 40% of non-drying, edible oil known as Ben Oil. This oil is clear, sweet and odorless, and never becomes rancid. Overall, its nutritional value most closely resembles olive oil. The thickened root is used as a substitute for horseradish although this is now discouraged as it contains alkaloids, especially moriginine, and a bacteriocide, spirochin, both of which can prove fatal following ingestion. The leaves are eaten as greens, in salads, in vegetable curries, as pickles and for seasoning. They can be pounded up and used for scrubbing utensils and for cleaning walls. Leaves and young branches are relished by livestock. The Bark can be used for tanning and also yields a coarse fiber. The flowers, which must be cooked, are eaten either mixed with other foods or fried in batter and have been shown to be rich in potassium and calcium.
In developing tropical countries, Moringa trees have been used to combat malnutrition, especially among infants and nursing mothers. Three non-governmental organizations advocate Moringa as “natural nutrition for the tropics.” Leaves can be eaten fresh, cooked, or stored as dried powder for many months without refrigeration, and without loss of nutritional value. Moringa is especially promising as a food source in the tropics because the tree is in full leaf at the end of the dry season when other foods are typically scarce. Analyses of the leaf composition have revealed them to have significant quantities of vitamins A, B and C, calcium, iron and protein. According to Optima of Africa, Ltd., a group that has been working with the tree in Tanzania, “25 grams daily of Moringa Leaf Powder will give a child” the following recommended daily allowances:
Protein 42%, Calcium 125%, Magnesium 61%, Potassium 41%, Iron 71%, Vitamin A 272%, and Vitamin C 22%. These numbers are particularly astounding; considering this nutrition is available when other food sources may be scarce.
Scientific research confirms that these humble leaves are a powerhouse of nutritional value. Gram for gram, Moringa leaves contain: SEVEN times the vitamin C in oranges, FOUR times the Calcium in milk, FOUR times the vitamin A in carrots, TWO times the protein in milk and THREE times the Potassium in bananas.
The Moringa tree has great use medicinally both as preventative and treatment. Much of the evidence is anecdotal as there has been little actual scientific research done to support these claims. India’s ancient tradition of ayurveda says the leaves of the Moringa tree prevent 300 diseases. One area in which there has been significant scientific research is the reported antibiotic activity of this tree.
This is clearly the area in which the preponderance of evidence – both classical scientific and anecdotal evidence – is overwhelming. The scientific evidence has now been available for over 50 years, although much of it is completely unknown to western scientists. In the late 1940’s and early 1950’s a team from India identified a compound they called pterygospermin. This group was also able to demonstrate its mode of antimicrobial action in the mid 1950’s. Field reports and ecological studies form part of a rich traditional medicine history claiming efficacy of leaf, seed, root, bark, and flowers against a variety of dermal and internal infections. In 1964 other active compounds were isolated and tested in-vitro, and these studies, along with observational studies provide a very plausible mechanism of action for the centuries of claims of efficacy. Unfortunately, because many of the reports of antibiotic efficacy in humans are not supported by placebo controlled, randomized clinical trials, Western medical prejudice leaves the Western world ignorant of Moringa’s antibiotic properties.
Another area of folklore which research supports is in cancer treatment. Moringa species have long been recognized by folk medicine practitioners as having value in the treatment of tumors. Studies examined certain compounds for their cancer preventive potential. Recently two of these compounds were shown to be potent inhibitors of activation of lymphoblastoid (Burkitt’s lymphoma) cells. One of these compounds also inhibited tumors in mice bred to be prone to tumors. In another study, Bharali and colleagues examined skin tumor prevention following ingestion of drumstick (Moringa seedpod) extracts. In this mouse model, which included appropriate positive and negative controls, a dramatic reduction in skin tumors was demonstrated. More rigorous study is required in order to achieve a level of proof required for full medical endorsement of Moringa as, in this case, a cancer preventative plant.
After the oil is extracted from the pods, the seed-cake remaining contains the active components for removing turbidity (solid particles) from water. Because bacteria adhere to the solids, this seed-cake also effectively removes bacteria. At the Thyolo Water Treatment Works in Malawi, Africa, two researchers from the University of Leicester, England, have worked on substituting moringa seeds for alum to remove solids in water for drinking. Not only were the tests successful in removing as much solid material as alum, but the seeds used were “purchased from enthusiastic villagers in Nsanje Region in Malawi” (Folkard and Sutherland, 1996. Not only is Moringa oleifera as effective as aluminum sulphate (alum) in removing suspended solids from turbid water, it has a major advantage. Because it can be produced locally, “using Moringa rather than alum would save foreign exchange and generate farm and employment income.” The potential for Moringa to create a new market for a community is there, and studies and projects are taking place examining this potential. Use of this natural substance would also remove a source of aluminum contamination.
This tree is truly a “miracle” tree offering hope; nutritionally, medicinally and economically to devastatingly poor 3rd world countries. It has just recently begun being used as a supplement in a juice form and in powdered leaf tablets.
