Drumstick Tree – Moringa oleifera

Print this entry

I was talking with Michael HindmarshSTFC, one of our members who’s a Vet down at Gerringong, south of Sydney about the Moringa as I’ve been wanting to do an article on this tree for a while so he sent me a note from the report he wrote while on a Churchill Fellowship to the UK & Europe in 1992 titled “The Biomanipulation of Blue-Green Algae” so those of you who have dams with this problem might like to have a chat with him. Ph: 02 4234 0281 He’s going to write an article on it for us. Michael studied Vet Science at Qld Uni between 1971-75. 

“The Horseradish Tree is being studied by Dr. Bill Grant and Mr. John Sutherland of the University of Leicester. A special role of this tree is growing in sewage wastes and producing seeds which can flocculate turbid water. John Sutherland is establishing pilot plants in Africa where landholders can grow the seeds then grind them to clean their water supplies. Bill has found a thousand fold reduction in bacteria from water samples treated with a meal from these seeds. Here is a new permaculture system capable of growing on sewage, producing pods for human consumption or a natural water flocculant.”

From the net: The idea of using moringa tree seeds to clear water came from the country of Sudan. The women there learned to use the seeds to clarify water from the muddy Nile River. The method works like this: When added to water, the crushed seeds attract particles of dirt that are floating in the water including certain disease organisms. The dirt attaches to the seeds and they fall together to the bottom of the jar. Then you pour off the good water to drink. However you must learn to follow all the steps carefully if you are going to clarify water with moringa seeds. The dirtier the water the more seeds you will need. After you have the correct number of seeds there are a number of steps including crushing the seeds, adding water to make a paste, shaking, straining, shaking again, and so on. If you don’t do all the steps you won’t have clean water. It’s been two hours since adding the seeds to the water and it’s clean. When people can’t boil dirty, polluted water, they can use moringa seeds.

George found the following from Aisha El-Awady:

The resilient, fast growing Moringa tree is packed with so many vitamins and nutrients and has such a high nutritional value that it has been rightly dubbed by some as the miracle tree. All parts of this scruffy looking tree are edible; the leaves can be eaten raw, cooked like spinach or made into a powder that can be added to sauces, soups or chowders. The new leaves have a tendency to appear towards the end of the dry season when few other sources of green leafy vegetables are available. The young, green pods can be eaten whole and are comparable in taste to asparagus. The older pods can be used for their seeds, which can be prepared as peas or roasted and eaten like peanuts. The flowers which bloom around 8 months after the tree is planted, can be eaten fried and have the taste and texture of mushrooms. In Hawaii, the flowers are used to make a tea that cures colds. In addition to this, the flowers are a year- round source of nectar and can be used by beekeepers. When the pods mature and turn brown, the seeds can be removed and pressed to extract high quality oil similar to olive oil rich in oleic acid (73%). The mature seed contains about 40% oil. The oil, which is known as Ben oil, can be used for cooking, lubrication, in soaps, lamps and perfumes. The oil was highly valued by ancient Greeks, Romans and Egyptians and was used in perfumes and for skin protection; it was also used in Europe in the 19th century for the same purpose and was imported from the West Indies. The taproot of young trees can be used to make a spice resembling horseradish when vinegar and salt are added to it. Not only is the Moringa oleifera tree extraordinary in that all parts of the tree are edible, but the most amazing aspect of the tree is its exceptionally high nutritional value. The leaves of the Moringa tree are an excellent source of vitamin A (four times the amount in carrots), the raw leaves are rich in vitamin C (seven times the amount in oranges), and they are also a good source of vitamin B and other minerals. The leaves are also an outstanding source of calcium (four times the amount in milk), protein (twice the amount in milk), and potassium (three time the amount in bananas). The content of iron is very good as well and the leaves have purportedly been used for treating anaemia in the Philippines. The content of amino acids such as methionine and cystine is also high. Carbohydrates, fats and phosphorous content are low making this one of the finest plant foods to be found.

Africa’s Solution to Malnutrition?      These qualities have made the Moringa oleifera tree a candidate in the fight against malnutrition. A group of health workers from the Church World Service have been utilizing this highly nutritious and fast growing tree as a means to cure and prevent malnutrition in infants, pregnant and lactating women as an alternative to the classic and expensive condiments usually used such as whole milk powder, sugar, vegetable oil, and sometimes peanut butter. It takes around ten days to see an improvement in malnourished infants when Moringa leaves are used whereas it takes months for recovery with conventional methods. According to Dr. Lowell Fuglie, the West Africa representative of the Church World Service who used the Moringa tree as a base for a nutrition program, “for a child aged 1-3, a 100 g serving of fresh cooked leaves would provide all his daily requirements of calcium, about 75% of his iron and half his protein needs, as well as important amounts of potassium, B vitamins, copper and all the essential amino acids. As little as 20 grams of leaves would provide a child with all the vitamins A and C he needs.”

“For pregnant and breast-feeding women, Moringa leaves and pods can do much to preserve the mother’s health and pass on strength to the fetus or nursing child. One 100 g portion of leaves could provide a woman with over a third of her daily need of calcium and give her important quantities of iron, protein, copper, sulfur and B-vitamins.”

 “One rounded tablespoon (8 g) of leaf powder will satisfy about 14% of the protein, 40% of the calcium, and 23% of the iron and nearly all the vitamin A needs for a child aged 1-3. Six rounded spoonfuls of leaf powder will satisfy nearly all of a woman’s daily iron and calcium needs during pregnancy and breast-feeding.”

Water Purification    The Moringa tree has other extraordinary qualities; the powder from ground Moringa seeds and the presscake left over from oil extraction have the ability to clear murky water as it acts as a coagulant which attaches to particulate matter and bacteria in the water and falls to the bottom of the container. The purified water can then be poured out and boiled. This method has been used for centuries domestically and has recently been tried commercially and was found to be equally efficient to, if not surpassing, alum which is usually used and at a fraction of the cost.

Practical Uses      The bark of the tree can be used to make mats or rope and in tanning hides. The gum from the cut tree trunks is used in calico printing and in some medicines. The wood can be used to make a blue dye and can also be used as firewood. The flowers and roots of Moringa trees contain a powerful antibiotic known as pterygospermin, which also has fungicidal properties. An effective plant growth hormone can be extracted from fresh leaves and has been found to increase crop yields by up to 25-30%, and the leaves can also be used as a green manure to enrich farmlands.

Mother’s Best Friend The family Moringaceae contains 14 species of Moringa trees. Moringa oleifera, is a drought tolerant tree, and is the best-known member of this family. It is native to sub-Himalayan regions of northern India and is distributed all over the world in tropics and sub tropics. Moringa stenopetala, which produces larger seed and leaves than M. oleifera, inhabits Ethiopia and northern Kenya. M. peregrina is native in Egypt, Sudan, and the Arabian Peninsula and as far north as the Dead Sea. M. ovalifolia is found in Angola and Namibia. The tree has many different names. It is called the drumstick tree in India due to the long pods, or the horseradish tree as the roots may be used to make a spice resembling horseradish. In some parts of the world it is known as ‘Mother’s best friend’. In Senegal, it is known as Nebeday, which means “Never Die,” because the tree is outstandingly hearty. It is also known as the Ben Oil tree; the Benzolive tree in Haiti; Marum in Thailand; Yoruba in Nigeria and Malunggay in the Philippines.                           www.islamonline.net/English/Science/2003/02/article06.shtml

Willi says

She heard that it is rich in B17 which is believed by some to be an anti cancer nutrient. In Indonesia all  parts of the plant are always cooked. Its Indonesian names are Klentang or Kelor. It was used to make a soup with Chicken to help recovery from sickness. The ingredients were leaves, pods, flowers, tamarind & chicken. The fibres from the pods had to be removed from the broth after cooking.

Living with our furred and feathered friends in the backyard by Ron Turner

I would like to quickly sum up my experiences in the bird and bat problem area by stating that when I wished to invest in horticulture on my property at Gympie, I grew macadamia nuts. As a result of listening to the problems of rural people over many years, offering advice and evaluating results, there is only one device of which I am aware that will give horticulturists and the smaller enthusiast protection from birds, flying foxes and possums, and that is netting. The claims of success of a particular device in preventing problem species of fauna accessing a fruit crop may, I suspect, relate more to the availability of an alternative non-netted food source. With the loss of a large scale eucalypt blossom event intrastate or even interstate due to seasonal conditions such as heavy rains, or drought or fire and the birds and bats are hungry, netting is the only sure way to enjoy your fruit. The problems associated with fauna and commercial or back yard crops are well known. In 1992 Dr. Mary Bomford was appointed as National Bird Pest Co-ordinator. She collated and published a bibliography of 561 bird pest research papers from around the world and compiled a list of bird pests from across Australia plus a list of then current bird pest research activities (Bureau of Rural Resources Working Paper WP/S/92).My own personal experiences at home trying various methods to keep birds and flying foxes off various fruits has been reinforced by the experiences of growers relying on one or more of the multitude of devices that whirr, whizz, bang or pop and that is birds and animals generally become habituated to such devices quickly and will learn to ignore them within a few hours to a few days. This was also the consensus of findings from researchers both in Australia and around the world. For example, I was to learn that my early use of electric fences to deter wallabies from my $10 a tree macadamias had a fundamental error. I failed to energise those wires on the day they were erected. I can picture the local wallabies sniffing the dead wire that first night, determining it posed no threat, and ignoring it for ever after. If you wish to employ various devices as aids to repel the invaders then you will have to be active in moving them frequently or reapplying time and again. The main thrust of experience here is that once the problem species has found your fruit and brought along the friends and relations, it is too late. You must be active with your plan and deterrents in hand well before your crop ripens. If you do not have a net, then you must consider failure. I, frankly, do not have the patience, or time, to be continually applying or moving a mixture of deterrents or repellents and our time-tested remedy is to erect netting over individual trees in our mixed orchard as required. This gives us protection from the fruit piercing moth, and a degree of protection from the Queensland fruit fly. I believe it is important to have a plan of action well before your particular crop matures and that plan should be under consideration at the planting phase. Included in the plan should be a personal attitudinal review whether you want the total crop, or are prepared to share some with our fauna. I personally find it difficult to sympathise entirely with growers who claim they did not forsee problems and now see lethal methods as the only way to protect their crop, or complain loudly when they cannot obtain a permit to destroy or move the offending fauna. Society, as a whole, has generally moved on past the gun and poison pot. Whether you plant some decoy crop to ripen just before your fruit, whether you work towards covering the costs of netting and perhaps cheaper types of frames to hold that netting up, or whether (as I tend to do with, say, mangoes) consider the luxury of eating fresh tree-ripened fruit may not be practical. Our choice often involves consideration of the rapidly increasing risk of loss of individual pieces of fruit combined with insect damage, or to pick when fauna are showing interest. While not all fruit will develop that delicious home grown flavour after picking, the mango, as a current example, will continue to ripen after picking. For me it may become a matter if I can tolerate my local brush turkey – for it is just one of 150 different birds I have recorded on our property and I like to have them around – or whether it is getting more fruit than I am comfortable with. I haven’t eaten, or tried to grow – a home grown banana for some years now. I get more of a thrill in seeing the king parrots and knowing the blossom bat and local sugar glider are probably enjoying the flowers and fruit.

Electric ‘Fencing’   Sheryl asked me about the use of electric wires to deter invaders. This method relies on a series of closely spaced and tensioned wires above the crop. The method utilises a bi-polar electric fence energiser that pulses much faster that an ordinary electric fence energiser and has three terminals (instead of the normal two); positive, negative and earth. If, say, 1000 volts is carried through each wire a bird or bat coming into contact with any two wires would receive a 2000 volt non lethal shock. This method failed in commercial stone fruit orchards during a ‘bad’ flying fox year. The flying foxes were said to have ‘yelped’ when they came into contact with the wires, tumbled through and commenced feeding. Both birds and flying foxes learned to access the orchard via the undefended walls. Note that the support structure for this method is more than that required for overhead netting. This grower obtained a measure of control by applying temporary bird ban netting. Another NSW grower reported using a similar overhead wire barrier method without electricity saying that the flying foxes found no difficulty accessing the fruit through the wires but seemed to have a slight problem in leaving the orchard.

For those with a leaning towards using non lethal electricity some deep thinking is required. What is the offending target species? In back yards or small orchards this may involve a wide range of birds, especially lorikeets and honey eaters, even satin or regent bower birds, etc. What gap between wires is to be employed? What is to be done around the sides? What is your legal position if someone is adversely affected by inadvertent contact with the wires, particularly those people with heart pacemakers? Tree limbs falling may require a daily check of the system; heavy grass growth may mean extra maintenance with grass cutting or weedicide spraying.  My understanding is that a permit may now be required to operate such a system.

Some considerations for those who have an electric fence energiser may provide inspiration:

  • If you have an orchard or vinyard situation with no other trees in the vicinity, provide some artificial perches for birds to utilize. If one was to use two bare wires held about a centimetre apart by insulators along those perches and connect them to the energiser the bird would receive a non-lethal shock
  • Electrified rods were being trialled in the USA some years ago for similar use in a vinyard and initial reports were said at the time to be encouraging. However, I believe birds will become habituated and learn to avoid the perches
  • Another device used with an energiser caused an old fluorescent tube wired into the line to flash with each pulse of electricity. This would need to be moved often, or allowed to move in the breeze to hopefully create moving shadows. It was also a quick check to determine whether the electric fence unit was working efficiently
  • I have read of  a hot wire connected to a spike embedded in river red gums being successful in repelling camels from chewing bark
  • If you don’t have an energiser and are seriously considering same it will probably be cheaper and more secure to mount the unit at the source of 240 volt supply and run a lead or hot wire to the source of action rather than purchase an energiser, solar cell and battery with its risk of theft. The major component of electric fencing is an efficient earth at least a metre into the ground; expect the voltage of the unit to fall a little under very dry conditions. An added ‘must have’ is some type of voltage tester.

N.B.      Dogs react quite severely to contact with a ‘hot wire’.

             Echidnas are readily killed by electrified wires placed close to the ground.

             Never electrify barb wire.

Noise    Research has shown that intermittent noise can actually lead to even more damage within an orchard as the birds or bats can leave a piece of fruit and return to  untouched fruit within the same or a different tree. Audible devices should not be used when likely to offend neighbours. Enforcement agencies tend to be ‘reactive’ in approach and cannot now afford to ignore complaints. Noise can be a serious problem in any noise emitting device unless one has extremely sympathetic neighbours. I recall bringing a noise emitting bird scarer from Victoria many years ago and trialling it on a commercial strawberry farm as the owner looked like losing her year’s income. I understand the local council sought the advice of the Mildura Shire Council about possible complaints of noise in their area. The device seemed to work locally but neighbours took offence and stole the control unit. Model planes and helicopters could also be employed either by the owner or a model enthusiast but these are very noisy and need to be well away from neighbours. Many years ago a Victorian featured a model aeroplane look-alike hawk for $2000. I know of large scale orchards using real planes to repel birds. Other loud ‘scaring’ noises such as gas guns, hail cannons, sirens, barking dogs or shooting were the cause of increasing complaint to departmental and council officers. Birds and flying foxes become habituated to these noises. I quote the example I was given of the willy-wagtail nesting in an operating gas gun. Other less offensive noises can be generated by stringing a length of tape tightly between two anchor points. Wind will cause a vibration sound. Mine seemed to protect my vegetable garden for a short while, until the wind dropped! I had similar luck when the wind dropped and my ‘look-alike’ flying hawk dropped off into daytime slumber. Crows entered the corn patch at a point furtherest away from my somnolent raptor, a distance of about 15 metres. I have used a crow sized piece of black plastic tied to the end of a long pole to flap in the breeze. Odd growers claimed some success with this variation of a hanging dead crow method. I still utilize and frequently move the plastic should my local crows become a short-term nuisance.

Electronic sounds   Two Australian scientists (Bomford and O’Brien 1990) examined the literature dealing with tests of devices that use sound to control bird damage. With the exception of distress and alarm call broadcasts (which showed potential) there was little scientific evidence to support claims of effectiveness for sonic devices in bird damage control. None of the devices reliably tested were likely to result in damage mitigation. They concluded that the value of bangers, clangers, poppers, bombers, sirens and most electronic noises on the birds and mammals tested is almost entirely limited to short-term control. The best effects were obtained when (1) sound is presented at random intervals, (2) a range of different sounds is used, (3) the sound source is moved frequently, (4) sounds are supported by additional methods such as distress calls of visual devices, and (5) sounds are reinforced by real danger, such as shooting. Much of the work in this field was carried out overseas now with varying claims of success. I am aware of different companies who currently offer devices emitting a variation of distress, alarm, and alert calls. The costs of these devices would put them beyond the reach of a small grower; close up the noise would be prohibitive. A Victorian company, Biosis Research P/L (Jaremovic 1990), was involved in the field of bio-acoustics until research funding ran out. Distress calls of some fauna may not repel, but bring others to investigate.

Bags  Various bags may be worth considering but generally have a disadvantage to the grower of not readily being able to see the colour of the fruit. I quote the example of a Gympie persimmon grower facing ruin from (mainly) rainbow lorikeets some years ago. During consecutive seasons he installed 140,000 and 110,000 paper bags over his fruit and was able to harvest and make a profit. 1994 prices were 4.5 cents for each bag and 4.5 cents to install each bag. He considered the mass of white bags had a deterrent effect on birds overflying his crop. While some lorikeets did rip these bags open such damage was negligible. However, I speculate if such fruit was left just that bit longer to ripen on the tree flying foxes may have followed the ethylene gases given off during the ripening process. (Scientists advised the acute senses of these animals allow them to detect ripening fruit from a distance of 500 metres). We utilize second hand carrot/onion net bags ex supermarket stores. These do allow an idea of fruit colour, assist in keeping fruit fly and piercing moth at bay, and will break down in about 12 months if overlooked. Friendly farmers may be happy to dispose of old 40kg fertilizer bags, while a Gympie company (may) have used jute coffee bags.

Offensive Odours  There are a host of  substances – apart from socks used in old gum boots –  which fall into the nasty odour category; they may not be popular with down-wind neighbours. As a generalization, these substances have to be re-applied after rain. I have no information as to the efficacy of using a ‘sticker’ with these repellents. As another generalization, it is/was unlawful to use a chemical on a crop for which it is not registered. For the personal use back-yarder I will merely say, ‘be careful’ of some of these substances, particularly if giving away or selling fruit. The real issue here is ‘how long does a substance repel in all weathers until efficacy is impaired and  re-application required?’

 While lion or tiger urine and elephant dung may be a little difficult to obtain,

  • local bean crop growers applying fungicides, e.g., Thiram, to their crops found it repelled wallabies and hares
  • several years ago New Zealand scientists researching chemical bird control discovered a product referred to as ‘C1’ which was said not to penetrate the skin of grapes. It had an LD50 to mice of 1600 ppm, but was repellent to birds.
  • About 1990, in South Australia (and the USA) research was being carried out on methyl anthranilate, said to be a non toxic substance. In one test a similar degree of repellency was recorded when the birds were again exposed 10 days later for food treated with 50% of the chemical
  • Other South Australian research was being carried out on another chemical aimed specifically at starlings and sparrows.
  • An American product known as ‘Sevana’ was made from a mixture of garlic powder and cayenne powder and was said to have a repellent effect although some reports suggested a residual impact on the flavour of grapes.
  • About 1990 New Zealand scientists developed a substance based on egg powder to repel hares and wallabies from young trees. Another egg-powder based repellent was developed in Victoria and I heard, only a few months ago, some Americans had also discovered an egg based repellent.

Netting   When I suggested netting as a solution to a particular bird or bat problem some years ago almost without exception growers responded by saying it is far too expensive. Many commercial growers went on to express amazement at the huge increase in fruit harvested after netting their crop; they didn’t know just how great their losses were. Some growers were able to recoup the netting cost within two seasons.  For the hobbyist, the potential loss of  prized fruit versus relaxing during the day and getting to sleep of a night means the only realistic way of protecting your fruit is to net. Small mesh netting aimed at excluding fruit fly will increase the humidity within the tree canopy which may lead to an increase in mites and mildews and loss of crop. It can also decrease the amount of light reaching the tree.

The issue, for me, in living with my furred and feathered friends, is what sort of net, where does one get it, and how is it used? I made up some samples of netting for the group. The DPI at Nambour were trying an exclusion net against fruit fly but you would build up the humidity inside the tree canopy and my experience is that you can increase the mite damage and lose a lot of your leaf with netting that dense. There are extruded nets and woven nets. Woven nets won’t snare your wildlife. Contact the DPI to find out the growers who have lost their nets and see if you can buy it.
