HelloPharmacist Scorecard of Mullein Verbascum thapsus Alcohol Free by Hawaii Pharm

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 27, 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 leaf extract in a concentrated dry form. Mullein is a plant traditionally used for respiratory support.

The liquid also includes glycerin and water as inactive ingredients to deliver the extract.

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 health and cough support.
  • We looked for evidence on: Asthma, Bronchitis, Cough, Influenza, Pneumonia, sore throat — 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 we hold on mullein for cough, bronchitis, asthma, diarrhea, and migraine headache is currently insufficient to rate it reliably. That means studies haven't yet built a strong enough case for or against its use for these conditions—not that it doesn't work, but that the data isn't settled.

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. The main caution comes from a small number of case reports describing dermatitis (skin inflammation) from topical contact with the whole plant or from breathing in plant dust occupationally; those patients also had sensitivities to other plants.

The safety data advise against use during pregnancy and while breastfeeding, as 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, or medications like aspirin), check with your doctor or pharmacist before starting this product—mullein may have mild blood-thinning effects that could add to theirs.

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.

Mullein leaf extract may appeal to someone looking for respiratory support, but the evidence for its effectiveness isn't yet established in our data. If you take a blood thinner or antiplatelet medication, check with your doctor or pharmacist before starting—the interaction is mild but worth confirming.

Short-term use is generally well tolerated, but safety in pregnancy and breastfeeding isn't clear enough to recommend it.

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.
