Herb
Chanca piedra
SavePhyllanthus niruri is a tropical herb used for kidney-stone support and urinary comfort.
Quick verdict
Its 'stone breaker' reputation is plausible, but human evidence is still modest and better for symptom support than guaranteed stone dissolution.
Evidence score
A rough internal score reflecting quantity, quality, and consistency of human evidence. Not a clinical recommendation.
What the research shows
Small human and animal studies suggest chanca piedra may reduce stone-forming tendencies and smooth-muscle spasm. Evidence is encouraging but not definitive.
Benefits

Typically used as tea or 500-1500 mg/day of extract equivalents.

Who should be cautious
May lower blood sugar or blood pressure slightly. People with kidney disease or on diuretics should be cautious.
