HelloPharmacist Scorecard of Breath Freshener by Wonder Laboratories

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 included for its possible benefits for high cholesterol and heart health, though the evidence is still developing.

Parsley seed concentrate is the second active ingredient—we hold no established evidence rating for its effectiveness in breath freshening or for any of the other uses sometimes claimed for parsley. The softgels also contain gelatin and vegetable glycerin as inactive ingredients (capsule material and thickener).

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: Freshen breath.
  • We looked for evidence on: Dry mouth, Gingivitis, Halitosis, Oral odor, Mouth freshness, Periodontal health.
  • The closest evidence on file: Sunflower Oil is rated "Insufficient Reliable Evidence To Rate" for Dry mouth (Natural Medicines).
  • Also on file: Sunflower Oil is rated "Insufficient Reliable Evidence To Rate" for Gingivitis.

We hold no effectiveness data for parsley seed concentrate for breath freshening or any oral health purpose. Sunflower seed oil is rated possibly effective for high cholesterol and coronary heart disease based on its fatty acid profile, though research is ongoing.

If you're taking this product for breath freshening specifically, the evidence backing that use isn't established in our data.

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 oil is generally well tolerated in normal dietary amounts, though concentrated supplements should be discussed with your doctor first. Allergic reactions are rare but possible in people sensitive to the ragweed family of plants (which includes sunflower).

Parsley seed concentrate is safe in the small, food-like amounts typically used, but concentrated extracts and large doses carry risks. At very high doses—200 grams of parsley oil or more than 10 grams of parsley's active compounds—serious effects like hemolytic anemia, kidney damage, and blood clotting problems have been reported.

Parsley is likely unsafe in pregnancy because it may stimulate the uterus; stick to normal food amounts only if pregnant. Safety data for parsley during breastfeeding is not on file.

Side effects, ingredient by ingredient Sunflower Oil Parsley

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?
  • 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.

If you take blood thinners (anticoagulants or antiplatelet drugs) or warfarin, double-check this product with your pharmacist—parsley increases bleeding risk and can reduce warfarin's effect. Also flag it before taking diabetes medications, diuretics, pentobarbital, sirolimus, or medications broken down by the liver enzyme CYP1A2.

If you have a known parsley allergy and take aspirin, the combination may worsen your reaction.

The bottom line

Scorecard at a glanceFully disclosed formula with no established evidence rating for its marketed use. Moderate medication interactions have been identified, and safety information is well characterized.

This product is primarily a concern if you take blood thinners, diabetes medications, diuretics, or certain other prescription drugs—the parsley ingredient has documented interactions with all of these. If you're on warfarin, pentobarbital, or sirolimus, check with your pharmacist before starting.

A person who's pregnant should avoid concentrated parsley products. Run your exact medications through the checker on this page.

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 Wonder Laboratories: Common Questions

Does Breath Freshener by Wonder Laboratories 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.
Is this safe to take if I'm pregnant?
Parsley seed concentrate is rated likely unsafe in pregnancy because it may stimulate the uterus. Stick to normal food amounts of parsley only if you're pregnant, and talk with your doctor or pharmacist before taking a concentrated supplement.
Can I take this if I'm on warfarin?
No—parsley contains vitamin K, which directly opposes how warfarin works. In large amounts, parsley can reduce warfarin's effectiveness. Talk to your pharmacist or doctor before taking any parsley supplement if you're on warfarin or any blood thinner.
What's the parsley seed oil in this product?
Parsley seed oil is listed as a blend, so its specific makeup isn't detailed here. The interactions and safety concerns we know about parsley are covered under the parsley seed concentrate ingredient, which is the active form included.
Could this help my bad breath?
We don't have evidence data showing parsley seed concentrate works for breath freshening. That use isn't established in our data, so we can't tell you whether it will help.
Is sunflower oil safe if I have diabetes?
Sunflower oil can theoretically raise fasting blood sugar in people with type 2 diabetes and may decrease how well your diabetes medication works. If you have diabetes, talk to your pharmacist or doctor before taking this product.
What if I have a ragweed allergy?
Sunflower allergies are very rare because sunflower oil has almost no protein. Even people with severe ragweed allergies usually tolerate sunflower oil fine, though a reaction is theoretically possible if you're sensitive to the Asteraceae plant family.
