P. amarus is an important plant of Indian Ayurvedic system of medicine which is used for stomach problems,and for the genitourinary system, liver, kidney and spleen.[5]The plant has long been used in Brazil and Peru as a supposed herbal remedy for kidney stones. Research among sufferers of kidney stones has shown that, while intake of Phyllanthus niruri didn't lead to a significant difference in either stone voiding or pain levels, it may reduce urinary calcium, a contributing factor to stone growth. One study conducted on rats showed that an aqueous solution of Phyllanthus niruri may inhibit kidney stone growth and formation in animals who already have stones.
