HelloPharmacist Scorecard of Mullein Flower 450 mg by TerraVita Premium Collection

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 Aug 20, 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.

TerraVita Premium Collection's Mullein Flower comes as a single active ingredient — 450 mg of mullein per capsule. The supplement also contains two inactive ingredients: gelatin (the capsule itself) and water.

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 Mullein product and its label doesn't state a use — see Mullein'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 mullein isn't settled yet. We don't have reliable data to rate whether it works for cough, bronchitis, asthma, diarrhea, or migraine headaches.

That doesn't mean it doesn't work — it means the studies we have aren't strong enough to say one way or the other. If you're considering it for one of these issues, talk with your doctor or pharmacist about whether there's better-studied options available.

The evidence, ingredient by ingredient Mullein

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.

Mullein is generally well tolerated for short-term use, though human safety data are limited. A small number of case reports have described dermatitis (a skin rash) after direct contact with the whole plant or from breathing in plant dust — in one case, the person had reactions to other plants too, so individual sensitivity may matter.

You should avoid mullein during pregnancy — there isn't enough safety information. The same goes for breastfeeding: there's not enough data to know whether it's safe, so it's best to skip it while nursing.

If you're pregnant, planning to become pregnant, or breastfeeding, talk with your doctor or pharmacist before taking this product.

Side effects, ingredient by ingredient Mullein

Meds to double-check

Minor interactions only
Known Interaction Concern · database check
Minor only

Only Minor-severity interactions are documented for these ingredients.

Why this rating?
  • 1 of the 1 matched ingredient can interact with medications — Mullein.
  • The most serious interaction on file is rated Minor.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs.
  • For scale: 122 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 before taking mullein if you're on any blood thinners or antiplatelet drugs — these include warfarin, aspirin, clopidogrel, dabigatran, and others in that class. The interaction is mild, but your doctor or pharmacist should know you're adding it so they can monitor you if needed.

The bottom line

Scorecard at a glanceFully disclosed formula with no assessable stated purpose. Only minor medication interactions are documented, and safety information is well characterized.

Mullein might be worth considering if you're looking at options for cough or respiratory issues, though the evidence isn't yet clear. If you take any blood thinners, check with your own doctor or pharmacist first — mullein can add a mild thinning effect.

Avoid it in pregnancy and while breastfeeding. For any questions about whether it's right for you and your other medications, talk it over with your healthcare provider.

Anticoagulant/Antiplatelet Drugs

Lab tests on extracts from different parts of common and dense-flowered mullein plants show that they do have some blood-thinning effects, as they increase the time it takes for blood to clot. This is likely due to at least one of the known constituents of muellein, triterpenoid saponins. However, the effects appear to be mild and results have been inconsistent. Extracts from different plant parts have been show to have varying anticoagulant strengths, with water-based ones being more potent than alcohol-based extracts.

Mullein Flower 450 mg by TerraVita Premium Collection: Common Questions

Does Mullein Flower 450 mg by TerraVita Premium Collection interact with any medications?
Yes. Based on its ingredients, Mullein Flower 450 mg has a known interaction with 122 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Mullein Flower 450 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.
What is mullein used for?
Mullein has been used traditionally for cough, bronchitis, asthma, and a few other conditions, but we don't yet have strong reliable evidence that it works for any of these. If you're thinking about it for a specific symptom, ask your doctor or pharmacist whether it might fit your situation.
Is mullein safe to use long-term?
We don't have much human data on long-term use — the safety information we have is mainly for short-term use. If you're thinking of taking it regularly for more than a few weeks, check with your pharmacist or doctor first.
Can I take mullein if I'm pregnant or breastfeeding?
No. There isn't enough safety data to know whether it's safe in pregnancy, so it's best avoided. The same applies to breastfeeding. Talk with your doctor or pharmacist if you're pregnant, planning to become pregnant, or nursing and want to discuss options.
Can mullein cause a rash or skin reaction?
A few case reports describe dermatitis (a rash) after touching the whole mullein plant directly or from breathing in plant dust. It's uncommon, but if you have sensitive skin or a history of plant allergies, be aware of this possibility.
Does this product have any fillers or other inactive ingredients?
Yes — the capsule contains gelatin and water in addition to the mullein. If you need a vegan capsule or have a gelatin sensitivity, you'll want to look for a different formulation.
