Chanca piedra is an herb that grows in tropical areas, like the rainforests of South America. Its scientific name is Phyllanthus niruri.
The plant has thin, leaf-covered branches and can grow up to about 2 feet (61 cm) tall. It gets the name “seed-under-leaf” because its seed pods, which bloom into small green flowers, grow beneath the leaves.
The entire plant — including the leaves, stems, and flowers — is used to make chanca piedra supplements.
As a supplement, chanca piedra is reported to help with a variety of conditions related to the digestive system, liver, and kidneys.
Supposedly, it contains phytochemicals — or plant compounds — that can increase urine flow, kill harmful bacteria and viruses, and relieve inflammation.
