HelloPharmacist Scorecard of Mullein Alcohol Free by Herbal Terra

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

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: mullein flower extract in dried form. Mullein has been used traditionally to support respiratory health.

The liquid is made with glycerin and water as inactive ingredients.

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 — see Mullein's own graded uses on its monograph.

Why this rating?
  • The label markets this product for: Respiratory support and cough relief.
  • We looked for evidence on: Asthma, Bronchitis, Cough, Influenza, Pneumonia, Chest congestion — and 2 related terms.
  • The closest evidence on file: Mullein is rated "Insufficient Reliable Evidence To Rate" for Bronchitis (Natural Medicines).
  • Also on file: Mullein is rated "Insufficient Reliable Evidence To Rate" for Asthma, Cough, Influenza, Pneumonia.

The evidence for mullein isn't established in the data we hold. We have insufficient reliable evidence to rate it for bronchitis, asthma, cough, migraine headache, or diarrhea.

That doesn't mean it doesn't work — it means the studies we have aren't robust enough yet to say either way.

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. Two case reports describe dermatitis (a skin reaction) after direct contact with the whole plant or from breathing in plant dust — both uncommon scenarios.

The safety data advise against use during pregnancy and while breastfeeding because there isn't enough information to know it's safe in those situations.

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.

If you take anticoagulant or antiplatelet drugs — blood thinners like warfarin, dabigatran, or aspirin, or antiplatelet medications — run them through the checker below or ask your pharmacist before adding this product to make sure the combination works for you.

The bottom line

Scorecard at a glanceFully disclosed formula with no established evidence rating for its marketed use. Only minor medication interactions are documented, and safety information is well characterized.

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 Alcohol Free by Herbal Terra: Common Questions

Does Mullein Alcohol Free by Herbal Terra interact with any medications?
Yes. Based on its ingredients, Mullein Alcohol Free 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 Alcohol Free 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.
Can I take this while pregnant or breastfeeding?
The safety data advise against it during pregnancy and while breastfeeding because there isn't enough information to know it's safe in those situations. Talk with your doctor or pharmacist about what's right for you.
What is mullein used for?
Mullein has been used traditionally to support respiratory health and is often taken for bronchitis, cough, and asthma. However, we don't have enough reliable evidence in our data to say how well it actually works for these uses.
What are the side effects?
Mullein is generally well tolerated for short-term use. A couple of case reports describe skin reactions after direct contact with the whole plant or from breathing in plant dust, but that's rare. Human safety data are limited, so if you notice anything unusual, let your pharmacist know.
Is this the same as the mullein I've heard about for cough?
Yes — this is mullein flower extract, the part commonly used. Traditional use for cough and respiratory support is well known, though the scientific evidence to back it up isn't solid in our data yet.
Does this product have any fillers?
It contains glycerin and water as inactive ingredients — these help make the liquid form. No other fillers are listed.
