Does it work?

Moderate evidence
Evidence for Intended Use · database check
By FDA rules, dietary supplements can’t claim to treat, cure, or prevent disease — so labels speak in careful marketing language. We discern each product’s intended use from its name, label claims, and label statements, then grade the clinical evidence for that use. How these ratings are computed
Moderate

Some clinical evidence supports this product's ingredients for its stated purpose, but it isn't conclusive.

Why this rating?
  • The label markets this product for: traditional support for kidney and gallstone health.
  • We looked for evidence on: Kidney stones (nephrolithiasis), Gallbladder disease, Urinary tract infections (UTIs), biliary colic, renal colic.
  • The strongest evidence on file: Chanca Piedra is rated "Possibly Effective" for Kidney stones (nephrolithiasis) (Natural Medicines).
  • Also on file: Chanca Piedra is rated "Insufficient Reliable Evidence To Rate" for Gallbladder disease, Urinary tract infections (UTIs), Colic.

In our data, chanca piedra is rated Possibly Effective for kidney stones. For hepatitis B, the evidence we hold rates it Likely Ineffective.

For anemia of chronic disease and benign prostatic hyperplasia (enlarged prostate), there isn't enough reliable evidence to rate whether it works.

The evidence, ingredient by ingredient Chanca Piedra

How safe is it?

Well-documented data
Safety Information · database check
Well characterized

Adverse-effect, pregnancy, and general safety data are on file for most of these ingredients.

Why this rating?
  • We hold adverse-effect (side-effect) data for 1 of the 1 matched ingredient.
  • Pregnancy & breastfeeding safety ratings cover 1 of 1.
  • General safety write-ups exist for 1 of 1.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Chanca piedra is generally well tolerated short-term, but high-quality long-term safety data are limited. The most common side effects reported with oral use are abdominal pain, nausea, and vomiting; one trial also noted fatigue.

The safety data advises against use during pregnancy and while breastfeeding because there isn't enough information to know whether it's safe in those situations.

The most serious documented interaction for these ingredients is Moderate. Check your medications for a personalized result.

Why this rating?
  • 1 of the 1 matched ingredient can interact with medications — Chanca Piedra.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; diabetes medications; lithium.

Before taking Stone Breaker, talk with your doctor or pharmacist if you're on any blood thinners or antiplatelet drugs (like warfarin or aspirin), diuretics (water pills), lithium, heart medications like norepinephrine, blood pressure medications, or diabetes medications.

The bottom line

Scorecard at a glanceFully disclosed formula with some supporting evidence for its stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

Stone Breaker may be worth considering if you're dealing with kidney stones and interested in herbal approaches, but you'll want to run it past your doctor or pharmacist first—especially if you take blood thinners, heart medications, blood pressure or diabetes drugs, or any medications your liver processes. The safety information doesn't support use in pregnancy or while breastfeeding.

Chanca Piedra8 drug types · 1,020 drugs

Anticoagulant/Antiplatelet Drugs

Theoretically, chanca piedra might increase the risk of bleeding when used concomitantly with anticoagulant/antiplatelet drugs.
In vitro research suggests that methyl brevifolincarboxylate, a constituent isolated from chanca piedra, can inhibit platelet aggregation. This effect has not been reported in humans.

Likelihood Possible Evidence D
Cytochrome P450 1A2 (Cyp1A2) Substrates

Theoretically, chanca piedra might reduce the levels and clinical effects of CYP1A2 substrates.
In vitro research shows that chanca piedra extract increases CYP1A2 activity. Theoretically, chanca piedra might increase metabolism of CYP1A2 substrates and lower serum concentrations. This interaction has not been reported in humans.

Likelihood Possible Evidence D
Cytochrome P450 3A4 (Cyp3A4) Substrates

Theoretically, use of chanca piedra might increase the levels and clinical effects of CYP3A4 substrates.
In vitro research shows that chanca piedra extract inhibits CYP3A4. Theoretically, chanca piedra might increase the levels of CYP3A4 substrates. This interaction has not been reported in humans.

Likelihood Possible Evidence D
Diuretic Drugs

Theoretically, concomitant use of chanca piedra with diuretics might increase diuresis.
Some preliminary clinical research in adults with hypertension shows that chanca piedra has diuretic properties. However, higher quality research in adults with kidney stones shows taking chanca piedra does not increase urine volume when compared with placebo. Until more is known, use cautiously in patients taking diuretic drugs.

Likelihood Possible Evidence D
Lithium

Theoretically, chanca piedra might reduce excretion and increase levels of lithium.
Some preliminary clinical research in adults with hypertension shows that chanca piedra has diuretic properties. However, higher quality research in adults with kidney stones shows that taking chanca piedra does not increase urine volume when compared with placebo. Until more is known, use cautiously in patients taking lithium. The dose of lithium might need to be decreased.

Likelihood Possible Evidence D
Norepinephrine (Levophed)

Theoretically, chanca piedra may reduce the effects of norepinephrine.
Animal research suggests that methyl brevifolincarboxylate, a constituent isolated from chanca piedra, can reverse blood vessel contraction caused by norepinephrine.

Likelihood Possible Evidence D
Antidiabetes Drugs

Theoretically, concomitant use with antidiabetes drugs might affect glucose control and increase the risk of hypoglycemia.
Animal research suggests that chanca piedra can have hypoglycemic effects. However, a small clinical study in adults with diabetes shows that chanca piedra extract 25 grams orally daily for 1 week does not lower fasting or postprandial blood glucose levels.

Likelihood Unlikely Evidence D
Antihypertensive Drugs

Theoretically, concomitant use of chanca piedra with antihypertensive drugs might have additive blood pressure lowering effects.
Animal research suggests that chanca piedra can decrease blood pressure. However, this effect was not observed in most hypertensive patients treated with chanca piedra for 10 days.
