HelloPharmacist Scorecard of Freeze Dried Parsley 385 mg 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 30, 2026

What’s inside

Full disclosure
Ingredient Transparency · database check
Full

Every active ingredient lists its own amount on the label.

Why this rating?
  • The label discloses an exact amount for 1 of its 1 active ingredient.
  • No proprietary blends here — you can verify the dose of every single component.

This product contains one active ingredient: freeze dried parsley at 385 mg per capsule. Parsley leaf is a culinary herb concentrated here into supplement form.

The capsules themselves are made of gelatin.

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

This is a single-ingredient Parsley product and its label doesn't state a use — see Parsley's own graded uses on its monograph.

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

The evidence for parsley supplement isn't established in the data we hold. The product is marketed for urinary tract infections, melasma, osteoarthritis, nonmelanoma skin cancer, and insect bites, but the research on all of these uses shows insufficient reliable evidence to rate whether it actually works.

The evidence, ingredient by ingredient Parsley

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.

Parsley is well tolerated at food amounts and low to moderate doses taken by mouth. Large doses can be unsafe — serious but rare side effects at very high intakes (200 grams of parsley oil or 10+ grams of its constituents apiole or myristicin) include hemolytic anemia, kidney or liver damage, and blood disorders.

A handful of cases of severe allergic reactions and anaphylaxis have been reported, even in people without a known parsley allergy. Because this is a concentrated extract, exercise caution if you have a parsley sensitivity.

Parsley in medicinal amounts may stimulate the uterus, so the safety data advises against use during pregnancy. For breastfeeding, safety data isn't on file — talk with your doctor or pharmacist about whether this product is appropriate for you.

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 — Parsley.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; diabetes medications.
  • For scale: 443 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 starting this product, double-check with your doctor or pharmacist if you take blood thinners like warfarin or antiplatelet drugs like aspirin (parsley contains vitamin K and may increase bleeding risk), diabetes medications (parsley may lower blood sugar), diuretics or water pills (parsley may interfere with their action), liver-processed medications (CYP1A2 substrates, which parsley may build up in your bloodstream), pentobarbital or other barbiturates (parsley may prolong their effects), or sirolimus or other immunosuppressants (parsley may raise their levels dangerously). No interactions are documented for ingredients we could not check, but the ingredient we could assess affects a substantial number of medications.

The bottom line

Scorecard at a glanceFully disclosed formula with no assessable stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

Freeze Dried Parsley is a single-ingredient concentrate marketed for several uses, but we don't have evidence it works for any of them. More importantly, parsley interacts with a wide range of medications — especially blood thinners, diabetes drugs, and diuretics — so you'll want to check your exact prescriptions and over-the-counter medications with your doctor or pharmacist before taking it.

Avoid it during pregnancy. If you take it, stick to normal food amounts rather than large supplement doses.

freeze dried Parsley8 drug types · 443 drugs

Anticoagulant/Antiplatelet Drugs

Theoretically, parsley might increase the risk of bleeding when taken with anticoagulant or antiplatelet drugs.
Animal research suggests that parsley has antiplatelet effects.

Likelihood Possible Evidence D
Antidiabetes Drugs

Theoretically, parsley might increase the risk of hypoglycemia when taken with antidiabetes drugs.
Animal research suggests that parsley might decrease blood glucose. Monitor blood glucose levels closely. Dose adjustments might be necessary.

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

Theoretically, parsley might increase serum levels of CYP1A2 substrates.
Laboratory research suggests that parsley can inhibit CYP1A2.

Likelihood Possible Evidence D
Diuretic Drugs

Theoretically, parsley might enhance or interfere with the effects of diuretic drugs.
Animal research suggests that parsley seed extract increases urine elimination. Parsley leaf and root might also interfere with diuretic therapy due their purported aquaretic effects.

Likelihood Possible Evidence D
Pentobarbital (Nembutal)

Theoretically, parsley might increase the duration of pentobarbital effects.
Animal research suggests that parsley juice prolongs the action of pentobarbital, perhaps by decreasing cytochrome P450 levels. It is not known if this occurs in humans or if this applies to other barbiturates or sedatives.

Likelihood Possible Evidence D
Sirolimus (Rapamune)

Theoretically, large quantities of parsley might increase sirolimus levels.
In one case report, an adult female with a history of kidney transplant presented with elevated blood sirolimus levels, approximately 4-7 times greater than previous measures, after daily consumption of a juice containing approximately 30 grams of parsley for 7 days. Sirolimus levels returned to normal a week after the parsley juice was discontinued.

Likelihood Possible Evidence D
Warfarin (Coumadin)

Theoretically, large amounts of parsley leaf and root might decrease the effects of warfarin.
Parlsey contains vitamin K.

Likelihood Possible Evidence D
Aspirin

Theoretically, aspirin might increase the severity of allergic reactions to parsley.
In one case, severe urticaria and swelling were reported after taking aspirin with parsley in an individual with a known mild parsley allergy.

Freeze Dried Parsley 385 mg by Dr. Clark Store: Common Questions

Does Freeze Dried Parsley 385 mg by Dr. Clark Store interact with any medications?
Yes. Based on its ingredients, Freeze Dried Parsley 385 mg has a known interaction with 443 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Freeze Dried Parsley 385 mg contains a single active ingredient, and that one ingredient can interact with many different medications on its own. We check it against each medication and show the mechanism 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.
Is parsley safe to take in large amounts?
Parsley at food amounts and low to moderate doses is generally well tolerated. Large doses can be unsafe — very high intakes carry a risk of serious side effects including anemia and kidney damage. This product is a concentrated supplement, so it's not the same as eating parsley in salad; stick to normal amounts and avoid megadoses.
Can I take this if I'm pregnant?
No. Parsley in medicinal amounts may stimulate the uterus, and the safety data advises against it during pregnancy. If you're pregnant or planning to become pregnant, talk with your doctor about whether this supplement is right for you.
Is there enough evidence that parsley works for UTIs or other conditions?
The evidence isn't established. The research on parsley for urinary tract infections, melasma, osteoarthritis, nonmelanoma skin cancer, and insect bites shows insufficient reliable evidence to rate whether it actually helps.
Can parsley cause allergic reactions?
Yes, though they're rare. A handful of cases of severe allergic reactions, including anaphylaxis, have been reported — some in people without a previous parsley allergy. If you have a sensitivity to parsley or related herbs, be cautious.
What is apiole and why does it matter?
Apiole is a compound in parsley that can cause serious side effects at high doses (10+ grams). Because this is a concentrated supplement, there's a greater risk of exceeding safe intake levels compared to eating parsley as food. Avoid very large amounts.
