India has a rich background traditional technologies. Varahamihira, an omni talented scientist of A.D 505–587 in his treatise entitled Brihatsamhita, suggested the use of five herbs for desalination of brakishwater. Laboratory tests are conducted on prepared and natural ground water samples. The optimum dosages of herbs at different chloride concentrations are determined. The performances of herbs, herbal mixtures and herbal extracts are determined by conducting experiments on percentage removals of chlorides. An effort is made to understand the mechanisms of herbal desalination by conducting experiments on adsorption, flocculation and variation of pH.
