Chanca Piedra has been used for centuries to support good kidney health. 

NIh.gov did a study on on the effects of Chanc Piedra in 2018.

This was their conclusion:

P.niruri intake is safe and does not cause significant adverse effects on serum metabolic parameters. It increases urinary excretion of magnesium and potassium caused a significant decrease in urinary oxalate and uric acid in patients with hyperoxaluria(a condition that occurs when there's too much oxalate in your urine. Kidney stones are usually the first symptom) . The consumption of P.niruri contributed to the elimination of urinary calculi. (kidney stones, STONEBREAKER!)

In other words...it busted up kidney stones.  Here is link to that article https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6092661/
