HelloPharmacist Scorecard of Stone Blaster by L.A. Naturals

Our pharmacy team’s full take, with four database checks built into the cards below — a summary of what is known, not a grade of the product itself.

From our pharmacy team — supplement deep dive

Generated from HelloPharmacist’s pharmacist-curated databases and editorial rules · Last generated Jul 11, 2026

What’s inside

Low disclosure
Ingredient Transparency · database check
Low

Most active ingredients don't disclose an individual amount — you can't tell how much of each you're getting.

Why this rating?
  • The label discloses an exact amount for 0 of its 1 active ingredient.

Stone Blaster contains one active ingredient: selectively imported chanca piedra, a plant used traditionally for kidney stone support. The formula also includes USP grain alcohol and deionized water as inactive ingredients.

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: kidney and gallstone support.
  • We looked for evidence on: Kidney stones (nephrolithiasis), Gallbladder disease, Urinary tract infections (UTIs), Renal health, Biliary function.
  • 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).

Chanca piedra is rated possibly effective for kidney stones (nephrolithiasis). For hepatitis B, the evidence rates it as likely ineffective.

The data we hold shows insufficient reliable evidence to rate its use for anemia of chronic disease or benign prostatic hyperplasia (BPH).

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 appears to be generally well tolerated in the short term, though high-quality long-term safety data are limited. The most common side effects reported are abdominal pain, nausea, and vomiting when taken by mouth.

One clinical trial also noted fatigue in some participants. There isn't enough safety information to recommend use during pregnancy or while breastfeeding — talk with your doctor or pharmacist before using Stone Blaster if you're pregnant or nursing.

Side effects, ingredient by ingredient Chanca Piedra

Meds to double-check

Moderate interaction found
Known Interaction Concern · database check
Moderate identified

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.
  • For scale: 1,021 individual medications appear in the full list. A big number alone doesn't make a product dangerous — what matters is whether YOUR medication is on it, so run yours through the interaction checker on this page.

Before you start Stone Blaster, double-check with your pharmacist if you take blood thinners or antiplatelet drugs (like warfarin, aspirin, or clopidogrel), diuretics, lithium, norepinephrine, medications for high blood pressure, or diabetes drugs. These carry documented interactions with chanca piedra, and your pharmacist can help you decide if it's right for you.

The bottom line

Scorecard at a glanceFormula with limited ingredient disclosure with some supporting evidence for its stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

Stone Blaster may be worth considering if you're dealing with kidney stones and want a traditional herbal option. However, if you take blood thinners, diuretics, lithium, blood pressure medications, diabetes medications, or any drugs your liver processes through CYP1A2 or CYP3A4 pathways, you'll want to check with your pharmacist first.

Avoid it in pregnancy and while breastfeeding unless your doctor says otherwise.

selectively imported 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.
