HelloPharmacist Scorecard of Verbascum Spp. Mullein by Wise Woman Herbals

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

Low disclosure
Ingredient Transparency · database check
Low

Most active ingredients don't disclose an individual amount — you can't tell how much of each you're getting.

Why this rating?
  • The label discloses an exact amount for 0 of its 1 active ingredient.
  • “Proprietary Blend” is a proprietary blend — the label gives one combined amount (2.50 mL) without saying how much of each component you get.

This product contains one active ingredient: mullein, a plant whose leaves and flowers have been used traditionally for respiratory and digestive concerns. The liquid form includes spring water, alcohol, and glycerin as inactive ingredients to deliver the mullein extract.

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 established in the data we hold. Studies haven't confirmed it works for bronchitis, asthma, cough, diarrhea, or migraine headache — the ratings across all these uses are insufficient reliable evidence to rate.

That doesn't mean it doesn't work; it means the research isn't there yet to say one way or the other.

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 describe dermatitis (skin irritation) from direct contact with the plant or from breathing in plant dust — mostly in people who also reacted to other plants.

For pregnancy and breastfeeding, there isn't enough data to know whether it's safe, so it's best avoided during pregnancy and lactation until more is known.

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 your blood thinners (anticoagulants or antiplatelet drugs) before you start mullein. Lab studies show the herb can lengthen clotting time slightly, which could add to the effect of drugs like warfarin, aspirin, or clopidogrel.

The bottom line

Scorecard at a glanceFormula with limited ingredient disclosure with no assessable stated purpose. Only minor medication interactions are documented, and safety information is well characterized.

Mullein is a traditional herbal remedy, but the research on whether it actually works for cough, bronchitis, or other conditions isn't solid yet. If you take blood thinners, check with us first — the herb may have mild blood-thinning effects of its own.

Talk to your pharmacist before starting, especially if you're pregnant, breastfeeding, or on any medications.

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.
