“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.”
