HelloPharmacist Scorecard of Breath Freshener by DC

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.

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 2 of its 2 active ingredients.
  • “Parsley seed Oil” is listed as a grouped ingredient — the label gives one combined amount (300 mg) without saying how much of each component you get.

This softgel contains two active ingredients. Sunflower seed oil is a plant oil used as a fat source in supplements.

Parsley concentrate is an extract from the parsley plant, included to freshen breath. The capsule itself is made from gelatin and vegetable glycerin.

Does it work?

Not established
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 established

The graded evidence we hold for these ingredients covers different conditions than the ones this product is marketed for, so there's no established rating for its stated use.

Why this rating?
  • The label markets this product for: breath freshening.
  • We looked for evidence on: halitosis, oral hygiene, mouth odor.
  • The closest evidence on file: Sunflower Oil is rated "Insufficient Reliable Evidence To Rate" for Dry mouth (Natural Medicines).

The evidence we hold doesn't establish how well this product works for breath freshening — that's not included in our data. Sunflower seed oil is rated possibly effective for high cholesterol and heart disease when used as a dietary oil, but that's different from its role here.

Parsley concentrate has insufficient evidence for the conditions listed in our records (urinary tract infections, skin concerns, arthritis, insect bites) — and again, breath freshening isn't covered in the data we hold.

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

Sunflower seed oil is generally well tolerated in normal dietary amounts, though concentrated supplement use should be discussed with your doctor. People allergic to plants in the ragweed family (ragweed, chrysanthemums, daisies) have a theoretical risk of allergic reaction, though the protein content is very low.

Parsley concentrate raises more caution. At normal food amounts it's well tolerated, but concentrated extracts and seeds may not be safe in large amounts — very high doses carry a rare risk of serious effects like anemia, low blood pressure, or kidney problems.

Parsley may stimulate the uterus, so medicinal or large amounts should be avoided in pregnancy; food amounts are likely fine. One case of severe allergic reaction (anaphylaxis) has been reported with heavy parsley use.

If you have a known parsley allergy, be cautious.

Side effects, ingredient by ingredient Sunflower Oil Parsley

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?
  • 2 of the 2 matched ingredients can interact with medications — Sunflower Oil, 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.

Check your medications against this product if you take blood thinners (anticoagulants or antiplatelet drugs), antidiabetes drugs, diuretics (water pills), drugs metabolized through the CYP1A2 liver pathway, warfarin, pentobarbital or other sedatives, sirolimus, or aspirin — especially if you have a known parsley allergy.

For each ingredient in Breath Freshener 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.

Parsley seed Oil8 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.

Likelihood Unlikely Evidence D
Parsley seed Oil full monograph & interactions

Sunflower Seed Oil1 drug type · 86 drugs

Antidiabetes Drugs

Theoretically, sunflower oil might decrease the effectiveness of antidiabetes medications.
A diet using sunflower oil as a fat source can cause increased fasting blood glucose levels in patients with type 2 diabetes. Dose adjustments to diabetes medications might be necessary.

Breath Freshener by DC: Common Questions

Does Breath Freshener by DC interact with any medications?
Yes. Based on its ingredients, Breath Freshener 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?
Breath Freshener contains 2 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.
Can I take this if I'm pregnant?
Parsley concentrate is rated likely unsafe in pregnancy — medicinal or large amounts may stimulate the uterus. Normal food amounts of parsley are likely fine, but since this is a concentrated supplement, talk with your doctor or pharmacist about whether it's right for you. Sunflower seed oil is rated likely safe in pregnancy.
What if I'm allergic to ragweed or daisies?
Sunflower seed oil can theoretically cause allergic reactions in people sensitive to the ragweed family (which includes chrysanthemums, marigolds, daisies, and other plants). However, sunflower oil has very low protein content, so actual allergic reactions are uncommon. If you have a severe allergy to these plants, mention it to your pharmacist before using this product.
Can I use this if I'm on warfarin?
No — parsley contains vitamin K, which can decrease warfarin's blood-thinning effects if you take large amounts. Do not use this product without talking to your doctor or pharmacist first.
What if I take diabetes medication?
Both sunflower seed oil and parsley may affect how well your diabetes medications work. Sunflower oil might decrease their effectiveness, while parsley might increase your risk of low blood sugar. You'll need your doses monitored closely. Check with your pharmacist or doctor before starting.
Is parsley safe at the amount in this product?
We don't have the exact dose listed in your product facts, so I can't say for certain. At normal food amounts, parsley is well tolerated, but concentrated supplements carry more risk — especially in people with allergies or on medications. Ask your pharmacist about the parsley dose in your specific product.
Are there any fillers in this?
The inactive ingredients are gelatin and vegetable glycerin — these are the capsule and what's used to hold it together, not medicinal fillers.
