HelloPharmacist Scorecard of Kidney Cleanse Tea by Dr. Clark Store

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 3 active ingredients.
  • “Proprietary Blend” is a proprietary blend — the label gives one combined amount (3,750 mg) without saying how much of each component you get.

This tea contains three active ingredients. Hydrangea and marshmallow are both thought to have diuretic properties (they increase urine output).

Gravel root is also included for its diuretic effects. Beyond these three, there are no other inactive ingredients listed.

Does it work?

Couldn't assess
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
Not assessable

The label doesn't state a purpose we can grade — see each ingredient's own graded uses on its monograph instead.

Why this rating?
  • We looked at the product name, claims, and label statements and couldn't find a stated purpose to grade.

The product facts we hold contain no effectiveness ratings for any of these three ingredients for kidney health or cleansing. Evidence supporting their use for that purpose isn't established in our data.

The evidence, ingredient by ingredient Hydrangea Marshmallow Gravel Root

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 2 of the 3 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 3 of 3.
  • General safety write-ups exist for 3 of 3.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Hydrangea and marshmallow are generally well tolerated for short-term use, though human safety data are limited. Gravel root requires particular caution because it contains pyrrolizidine alkaloids, compounds that can cause liver and lung damage.

Chronic exposure to these alkaloids may lead to veno-occlusive disease, a serious liver condition with symptoms like abdominal pain, vomiting, diarrhea, and fluid buildup (ascites), followed by persistent liver enlargement. All three ingredients should be avoided during pregnancy and breastfeeding due to insufficient safety data.

Hydrangea and marshmallow may cause side effects including gastroenteritis, dizziness, and chest tightness.

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?
  • 3 of the 3 matched ingredients can interact with medications — Hydrangea, Gravel Root, Marshmallow.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; lithium.
  • For scale: 2,050 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.

Check with your pharmacist if you take lithium (moderate interaction with all three ingredients), CYP3A4 inducer medications like carbamazepine, phenobarbital, phenytoin, rifampin, or rifabutin (moderate interaction with gravel root), any oral medications (minor interaction with marshmallow's effect on absorption), or blood thinners or antiplatelet drugs (minor interaction with marshmallow flower).

The bottom line

Scorecard at a glanceFormula with limited ingredient disclosure with no assessable stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

If you take lithium, any CYP3A4 inducer medications, or blood thinners, talk with your pharmacist before using this tea—dosage adjustments may be needed. Because gravel root carries liver and lung toxicity risks, this product is best used short-term and under caution.

Pregnant or breastfeeding individuals should avoid it.

For each ingredient in Kidney Cleanse Tea with known interactions, here are the types of medications they can affect. Open any type for the detail — or search your exact drug in the checker above.

Marshmallow3 drug types · 2,040 drugs

Lithium

Theoretically, due to potential diuretic effects, marshmallow might reduce excretion and increase levels of lithium.
Marshmallow is thought to have diuretic properties. To avoid lithium toxicity, the dose of lithium might need to be decreased when used with marshmallow.

Likelihood Probable Evidence D
Anticoagulant/Antiplatelet Drugs

Theoretically, marshmallow flower might have antiplatelet effects.
Animal research suggests that marshmallow flower extract has antiplatelet effects. However, the root and leaf of marshmallow, not the flower, are the plant parts most commonly found in dietary supplements. Theoretically, use of marshmallow flower with anticoagulant/antiplatelet drugs can have additive effects, and might increase the risk for bleeding in some patients.

Likelihood Unlikely Evidence D
Oral Drugs

Theoretically, mucilage in marshmallow might impair absorption of oral drugs.
Marshmallow contains mucilage which can affect oral drug absorption. To avoid changes in absorption, take marshmallow 30-60 minutes after oral medications.

Likelihood Possible Evidence D

Gravel Root2 drug types · 88 drugs

Cytochrome P450 3A4 (Cyp3A4) Inducers

Hepatotoxic pyrrolizidine alkaloids (PA) are substrates of cytochrome P450 3A4 (CYP3A4). Theoretically, drugs that induce CYP3A4 might increase the conversion of PAs to toxic metabolites. Some drugs that induce CYP3A4 include carbamazepine (Tegretol), phenobarbital, phenytoin (Dilantin), rifampin, rifabutin (Mycobutin), and others.

Likelihood Possible Evidence D
Lithium

Gravel root is thought to have diuretic properties. Theoretically, due to these potential diuretic effects, gravel root might reduce excretion and increase levels of lithium. The dose of lithium might need to be decreased.

Kidney Cleanse Tea by Dr. Clark Store: Common Questions

Does Kidney Cleanse Tea by Dr. Clark Store interact with any medications?
Yes. Based on its ingredients, Kidney Cleanse Tea has a known interaction with 2,049 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Kidney Cleanse Tea contains 3 active ingredients, and an interaction can come from any of them. We check every ingredient, combine the results into one list per medication, and show which ingredient and mechanism is responsible.
Where does this information come from?
The product label data comes from the NIH Dietary Supplement Label Database (DSLD); the interaction data is built on the Natural Medicines database and reviewed by HelloPharmacist pharmacists.
What does this tea do?
The product contains hydrangea, marshmallow, and gravel root—all thought to have diuretic properties that increase urine output. However, we hold no effectiveness data in our files showing they work for kidney cleansing or any other specific purpose.
Can I take it if I'm pregnant or breastfeeding?
No. All three ingredients should be avoided during pregnancy and breastfeeding because there isn't enough reliable safety information. Talk with your doctor or pharmacist about what's safe for you.
What side effects might I notice?
Hydrangea and marshmallow may cause gastroenteritis, dizziness, and chest tightness. Gravel root's main concern is its pyrrolizidine alkaloid content, which can damage the liver and lungs; chronic use may lead to veno-occlusive disease with abdominal pain, vomiting, diarrhea, and liver enlargement.
How long is it safe to use?
Both marshmallow and gravel root should be used short-term only. Gravel root carries particular liver and lung toxicity risks, so it requires cautious, limited use.
Does it interfere with other medications I take by mouth?
Yes, marshmallow contains mucilage that may reduce how your body absorbs oral drugs. To minimize this, take marshmallow 30–60 minutes after your other medications.
