SHARE-funded research  has found that Moringa oleifera, a common plant in many tropical and subtropical countries, can be an effective handwashing product if used in the correct concentration. Laboratory tests show that the plant has antibacterial activity against different pathogen, but its potential effect as a hand washing product had not been studied before.
By testing the effect of Moringa oleifera leaf powder on hands artificially contaminated with E. coli and comparing this to the effect of non-medicated liquid soap, the researchers from the London School of Hygiene and Tropical Medicine and SBI Consulting Ltd in Mozambique found that four grams of Moringa oleifera powder had the same effect as non-medicated soap when used for hand washing.
The next step will be to try this product in real conditions and study its acceptability and convenience for potential users.
