Disinfection of drinking water is very important to prevent the waterborne disease caused by various pathogenic infections.Dhaka isone ofthe most densely populated megacities in the worldwhere safe drinking water remains as one of the major pervasive problems.Previous studies showed thatboth surface water, and supplied water by Dhaka Water Supply & Sewerage Authority (WASA)are heavily contaminated with a variety of pathogenic bacteria and thus, a huge number of people has been suffering from waterborne diseases round the year.Although, there are severaleffective modern methods for water purificationbuttheymight pose chemical threats to the human health.In thepresentstudy, wehave used the ancient Ayurvedic knowledge to explorethecheap and effective methodsfor disinfectingsuppliedcommonly consumed drinking water. Accordingly, we have chosen eight different popular localherbs and preparedseveral poly-herbal combinations of these herbs. Interestingly, among these combinations,threepoly-herbal combinations found to be very effective to disinfectthecontaminated drinkingwater.Although, the results are promising, further research isnecessary toreveal the molecular mechanism of actions of the poly-herbal combinations aspotentdisinfectant.
