Now scientists are investigating their properties in depth, as Sue Nelson andMarlene Rau report.In the foothills of the Himalayas grow trees, five to ten metres tall, with clusters of small oval leaves and delicately perfumed cream-coloured flowers. These are Moringa oleifera – the most widely cultivated of the 14 species of the genusMoringa, known as ‘miracle trees’.“It is called a miracle tree because every part of the tree has benefits,” says Balbir…show more content…
This is then swirled around in the bucket of turbid water, until the fine particles and bacteria clump together with M. oleifera powder, sinking and settling to the bottom. For drinking water though, the water needs to be purified further – by boiling, filtering through sand or placing it in direct sunlight in a clear bottle for a couple of hours (solarising; seeFolkard et al., 1999). You can try a similar technique yourself in class (see box).

Researchers already know that the active ingredient in the seeds is protein, which accounts for 30-40% of the seeds’ weight. There are at least two proteins that may be active: they are water-soluble and quite small, about 6-16 kDa, so they can readily diffuse out of the cloth bags. At higher concentrations, they aggregate even in solution due to their substantial hydrophobic regions. The protein adsorbs onto contaminant particles, which then clump together
