    In vitro studies attempting to dissolve urinary calculi
    (Sri Lanka Medical Association. Colombo, 1986) Saravanapavananthan, S.; Mageswaran, R.
    38 urinary calculi obtained at surgery were analsed and some of them were left in an indigenous preparation used by siddha aayurvedic physician called "nandukal pasmum" This preparation contain mainly calcium carbonate which in water gives as alkaline solution of NAdukal pasmum. The probable mechanism of action is that when uric and mono urates are the principle constituents of the calculi them form diurates which are more soluble in an alkaline solution. Hence the stones can dissolve when sodium or potassium diurates are formed or disintegrate into a power when calsium diurate is formed
