Calcium oxalate (CaOx) being a major inorganic constituent of human kidney stones‚ contributes around 70-80% of the kidney stone. In India‚ approximately 5-7 million patients are suffering from kidney stone disease [6] (Kaladhar et al.‚ 2012). Urinary oxalate is found to be a major factor for calcium oxalate stone formation. As the molar ratio of oxalate-to-calcium is normally 1:10‚ slight changes in urinary oxalate concentration may cause crystallization and stone

table it was found that the calcium oxalate content in fresh tuber were 0.14% in elephant foot yam‚ in karunai kizhangu 0.25% and in taro 0.20 percent respectively. The processed (soaking the tubers in citric acid followed by blanching‚ drying & roasting) tuber flour was subjected to determine the presence of calcium oxalate. It was found that elephant foot yam flour had 0.05%‚ karunai kizhangu flour contained 0.09% and in taro flour had 0.08 percent calcium oxalate. The reduction in acridity was noticed
