What should you know about chanca piedra for kidney stones?

Chanca piedra is promoted for kidney stones, but it should not replace medical assessment or proven treatment for a blocked urinary tract. A stone's size, location, composition, symptoms, kidney function, and the presence of infection affect management. Herbal products can vary in strength and may interact with medicines.

A kidney stone can irritate the urinary tract, obstruct urine flow, or contribute to infection. Chanca piedra may be sold as tea, capsules, or an extract, but the product name does not confirm that it will dissolve or pass a particular stone. Delaying care while relying on a supplement can allow obstruction or infection to worsen. Tell a clinician about pregnancy, kidney disease, allergies, and every supplement you take.

Arrange a [GP Consultation](/treatments/consultations-and-assessment/gp-consultation/) for new or recurring stone symptoms. Do not force large amounts of fluid if you are vomiting or have been told to restrict fluids. A clinician may use urine tests, blood tests, and imaging such as an [Abdominal Ultrasound](/treatments/diagnostics-and-screening/abdominal-ultrasound/) to assess the stone and urinary tract. Ask before taking chanca piedra with prescribed medicine.

Get urgent medical help for fever or chills with flank pain, severe or worsening pain, repeated vomiting, blood in urine, or [Difficulty Passing Urine](/symptoms/difficulty-passing-urine/). Seek prompt assessment for [Painful Urination](/symptoms/painful-urination/) or persistent [Flank Pain](/symptoms/flank-pain/), especially if you may be [Dehydrated](/conditions/dehydration/). These symptoms can signal obstruction or infection.

Ask whether imaging is needed, where the stone is located, whether it is likely to pass, what pain relief is suitable, and whether chanca piedra could interact with your medicines or affect kidney function.
