niruri is an important plant of Indian, Ayurvedic, system, of medicine, which, is used, for problems, of the, stomach, genitourinary, system, liver, kidney , spleen.[1][2] The plant has also been used in Brazil and Peru as a herbal remedy for kidney stones.A clinical study with Phyllanthus niruri, indicated that it may reduce the levels of urinary calcium.[3] A subsequent study of 150 patients over a 6-month period indicated that an extract of this herb reduces the incidence of stone formation, and concluded, “Regular self-administration of P. niruri after extracorporeal ,shock, wave ,lithotripsy, for renal, stones, results, in an increased stone-free rate that appears statistically significant for lower caliceal location. Its efficacy and the absolute lack of side effects make this therapy suitable to improve overall outcomes after extracorporeal shock wave lithotripsy for lower pole stones.”[4] A more recent rat study found that Phyllanthus niruri has been shown to interfere with many stages of stone formation, reducing crystals aggregation, modifying their structure and composition as well as altering the interaction of the crystals ,with ,tubular, cells, leading ,to reduced ,subsequent endocytosis.https://en.wikipedia.org/wiki/Phyllanthus_niruri
