C
Evidence

Chanca piedra (Phyllanthus niruri) is a traditional Amazonian herb with preliminary evidence suggesting potential benefits for kidney stone management and urinary tract health. Most human studies are small and of moderate quality, with stronger evidence needed for definitive efficacy claims.

Primary uses

  • Urinary tract health
  • Liver support
  • Antioxidant support

How it works

  • Potential crystallization inhibition in urine
  • Anti-inflammatory and antioxidant activity via polyphenols
  • Possible antispasmodic effects on urinary tract
  • May affect calcium oxalate crystal formation

Evidence notes

Limited human clinical trials with modest sample sizes. Some in vitro and animal studies support traditional uses, but controlled RCT evidence in humans is sparse. Traditional use in Amazonian medicine is well-documented but does not establish clinical efficacy by modern standards.

Grade C: Mostly observational or small trials; mechanism is plausible but unproven at scale.
