A recipe for using "the world's most useful tree" to purify water is being offered for free download, in the hope that this will help get clean drinking water to billions of poor folk around the world.

The Swiss Army knife of the tree world

The tree in question is the Moringa oleifera ("oily moringa") aka the horseradish or drumstick tree (also "Mother's best friend" in some places). The Moringa is cultivated across the tropical world and furnishes food in the form of apparently highly nutritious* pods, leaves and flowers.

It also yields oil which can be used as lighting or cooking fuel (or to make biogas). You can even make a highly effective crop fertiliser out of the miracle Moringa. Handily, the trusty tree is also drought resistant and tolerant of poor soil.

But that's not all, it turns out. You can also use Moringa products to inexpensively purify dirty drinking water.

“Moringa oleifera is a vegetable tree which is grown in Africa, Central and South America, the Indian subcontinent, and South East Asia. It could be considered to be one of the world’s most useful trees,” says Michael Lea, a Canadian water-purification researcher. “Perhaps most importantly, its seeds can be used to purify drinking water at virtually no cost.”

The method in outline involves crushing the tree's seeds to powder and making a solution with this. When the solution is added to turbid, dirty water it causes the suspended gunge to rapidly stick together into bigger flecks and so sink rapidly. Almost all contamination is thus carried down quite quickly into a sludge at the bottom of the container, allowing nice clear water to be decanted or siphoned off from the top.

The Moringa-seed technique, according to Lea, isn't foolproof - there are various bacteria and viruses which will not be affected by it. But it makes water much safer and more pleasant to drink, and Moringa treatment is hugely better than no treatment at all, which is the norm for far too many people.

“This technique does not represent a total solution to the threat of waterborne disease," concedes Lea. "However, given that the cultivation and use of the Moringa tree can bring benefits in the shape of nutrition and income as well as of far purer water, there is the possibility that thousands of 21st century families could find themselves liberated from what should now be universally seen as 19th century causes of death and disease.

"This is particularly mind-boggling when you think it might all come down to one incredibly useful tree.”

According to Lea, despite the fact that Moringa is widespread in the very regions where bad water is a serious problem, the seed-paste purification method is little known. Thus his paper on just how to do it is being published for free online.

Now all that's needed is for the knowledge of the recipe to spread. We don't suppose we have all that many readers in regions where it would be useful, but perhaps some of you can pass it on. ®

*The leaves of the Moringa are said by some sources to be several times as rich in the relevant desirable vitamins and minerals as orange juice, bananas, carrots and milk.

Was wondering if anyone has some plants to trade of this guy

I have seed pods on my trees at the moment, still green will let you know when they're ripe if interested.

Anyone got any good recipes for using the leaves? they have a very strong taste, a bit much to eat raw.

i sprinkle a few young leaves into salads. adds a nice radish flavour.

when I browse in the garden I get one mousemelon, one cherry tomato, and a moringa leaftip and chew it all up together for an instant salad.
