What Chanca Piedra Stone Breaker is, and what it does.
- Does it work
- Promising for kidney stone prevention. Evidence is supportive but not definitive.
- How much to take
- 1-2g dried herb or 500-1000mg extract daily.
- Time to feel it
- Urine output often shifts within a day or two. Anything measured in urine chemistry is followed over weeks to months rather than from a single dose.
- The first dose
- Day one usually means more trips to the bathroom, since it has a mild diuretic action. Anything happening in urine chemistry is measured over weeks, not on day one.
- With regular use
- Reduced stone recurrence for some. May help pass small stones over time.
- How well tolerated
- Well tolerated in short use. Its tannins cut mineral absorption in the same swallow, and it can interact with blood pressure, glucose and blood-thinning medicines, so ask your clinician.
- How it feels
- More urination. Possibly easier passing of small stones.
- The overlooked benefit
- Its tannins bind minerals in the same swallow, non-heme iron most of all, so leaving a couple of hours between it and an iron or mineral serving keeps both intact.
500 to 1,000mg a day is where Chanca Piedra Stone Breaker works.

Questions people ask about Chanca Piedra Stone Breaker.
- How does it work?
- Multiple mechanisms: inhibits crystal formation, relaxes ureters, increases urine output.
- Can I use it during a stone attack?
- It might help, but see a doctor for acute stone pain. You may need medical treatment.
- Any drug interactions?
- May affect blood sugar and blood pressure medications. Consult your doctor.
- Does it work for gallstones too?
- Traditional use includes gallstones. Less studied than kidney stones.
Why these belong in the same formula. Each row says what the basis is, from settled biochemistry through to a trial that measured the pair.
Citrate is excreted in urine where it binds free calcium and holds it in solution, supporting normal urinary mineral balance, and magnesium itself competes with calcium for oxalate. Chanca piedra is used traditionally on the same urinary axis.
Potassium citrate raises urine pH and urinary citrate, which keeps calcium and uric acid more soluble. It is the settled mineral partner for a botanical aimed at normal urinary crystal balance.
Pyridoxal phosphate is the cofactor for alanine glyoxylate aminotransferase, which routes glyoxylate to glycine instead of oxalate. Less endogenous oxalate means less urinary calcium oxalate load.
Phyllanthus extracts are rich in hydrolysable tannins and ellagitannins that bind ferric iron in the gut lumen into complexes the enterocyte cannot absorb. Space an iron dose away from the extract.
Potassium intake influences renal sodium handling and, when supplied as an organic salt, contributes alkali that raises urinary citrate excretion. Citrate in urine binds calcium and reduces the supersaturation that drives crystal formation. Both effects are urinary chemistry, which is a measurable marker rather than a clinical outcome.
Magnesium competes with calcium for oxalate in solution and forms a more soluble complex, so magnesium present in the gut lumen lowers the amount of free oxalate available to pair with calcium. Urinary magnesium likewise raises the concentration at which calcium oxalate begins to crystallise. This is solution chemistry with a long-established basis.
Dietary calcium taken with an oxalate-containing meal binds oxalate in the gut lumen as insoluble calcium oxalate, which leaves in the stool rather than being absorbed. Lower absorbed oxalate means lower urinary oxalate. Counterintuitively, timing calcium with meals rather than away from them is what produces this effect.
Ascorbate degrades to oxalate as one of its metabolic and non-enzymatic breakdown products, and high supplemental doses raise measured urinary oxalate excretion. That works against anything aimed at lowering urinary oxalate. The consideration applies to gram-level doses rather than to ordinary dietary intake.
Glycine is converted to glyoxylate, and glyoxylate is the immediate precursor that alanine-glyoxylate aminotransferase and lactate dehydrogenase route either back to safety or onward to oxalate. Large glycine loads therefore feed the oxalate pool. This is a pathway relationship worth naming rather than a reason to avoid glycine at ordinary intakes.
Calcitriol raises intestinal calcium absorption by inducing the transport machinery in the enterocyte, and higher absorbed calcium can raise urinary calcium excretion. Urinary calcium is one of the terms in calcium oxalate supersaturation. Anyone monitoring urinary mineral chemistry should count the vitamin D dose as part of the picture.
Some gut bacteria, most notably Oxalobacter formigenes and certain lactic acid bacteria, degrade oxalate in the intestinal lumen using oxalyl-CoA decarboxylase. Degrading oxalate before it is absorbed lowers what reaches the urine. Whether a given probiotic product carries oxalate-degrading capability is strain-specific and usually not stated.
Bicarbonate is an alkali load that raises urinary pH and urinary citrate excretion. Uric acid solubility rises steeply with pH while calcium phosphate solubility falls, so alkalinisation is not uniformly favourable across crystal types. It also carries a sodium load, and sodium raises urinary calcium.
Dandelion root and leaf have a long documented record of use for supporting normal urine volume, and the leaf is a notable potassium source. Combining two botanicals with the same traditional use raises total fluid turnover. Neither the combination nor either component's urinary effect is established at trial level here.
Marshmallow root is rich in mucilage polysaccharides that form a demulcent film on mucosal surfaces, which is the documented basis for its traditional use for urinary and throat comfort. That is a physical coating mechanism, unrelated to crystal chemistry. The pairing is a formulation convention.
Cranberry supplies A-type proanthocyanidins associated with reduced bacterial adhesion to urothelium, plus quinic and citric acids that alter urinary composition. It also contains oxalate, so a high cranberry intake adds to the oxalate load. Both directions are worth stating rather than only the favourable one.
Aerial parts of Phyllanthus niruri carry tannins and other polyphenols, and these chelate divalent cations in the gut lumen and lower their absorbed fraction. Zinc is among the minerals affected. Separating a zinc dose from a tannin-rich extract by a couple of hours removes the overlap.
Turmeric rhizome is among the higher-oxalate culinary plants, and gram-level powder intakes contribute measurably to oxalate load. A standardised curcuminoid extract carries far less of the root matrix than the whole powder does. Which one is in the formula decides whether this matters.
Silymarin is a flavonolignan complex used in formulas aimed at supporting normal liver function, and Phyllanthus species appear in the same category of traditional formula. The two are paired by convention rather than by a shared mechanism. No combination data supports the pairing.
Urine solute concentration is a function of solute load divided by water volume, so anything that raises fluid intake lowers supersaturation for every crystal type at once. Electrolytes support the fluid intake that makes that dilution sustainable. The sodium content of the blend is the part to watch, since sodium raises urinary calcium.

Chanca piedra is the aerial part of Phyllanthus niruri, a small annual of the Phyllanthaceae found across tropical South America and Asia. The traded material is the whole above-ground plant, and closely related Phyllanthus species are a documented substitution risk because they are hard to tell apart once dried.
The characteristic constituents are the lignans phyllanthin and hypophyllanthin, together with hydrolysable tannins such as corilagin and geraniin, flavonoids including quercetin glycosides, and alkaloids of the securinine type. Phyllanthin is the usual standardisation marker because it is specific to the genus.
Whether calcium oxalate crystals form in urine depends on supersaturation, which is set by the concentrations of calcium and oxalate divided by the solubility product, and on the inhibitors present. Citrate and magnesium raise the concentration at which crystals nucleate by complexing calcium and oxalate respectively, and higher urine volume lowers every concentration term at once.
Hydrolysable tannins chelate divalent and trivalent metal cations and precipitate proteins, so a tannin-rich aerial-part extract lowers the absorbed fraction of minerals taken in the same swallow. Non-heme iron is the mineral most affected in ordinary practice.
