HelloPharmacist Scorecard of Mullein 330 mg by Solaray

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, 330 mg per capsule. Mullein is a plant used in traditional herbal practice.

The capsule also contains cellulose as an inactive ingredient.

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: Herbal respiratory and throat support.
  • 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 we hold doesn't establish that mullein is effective for any condition. It's been studied for bronchitis, asthma, cough, diarrhea, and migraine headache, but available data are insufficient to rate it reliably for any of these uses.

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 overall. The main safety concern is contact dermatitis (skin irritation) — a small number of case reports describe rash after direct skin contact with the whole plant or from breathing in plant dust during handling.

The safety data advise against use during pregnancy and while breastfeeding.

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 this supplement against any blood thinners or antiplatelet drugs you're taking — warfarin, dabigatran, apixaban, rivaroxaban, clopidogrel, prasugrel, aspirin, and others. The interaction is rated Minor, but blood thinners warrant caution with anything that affects clotting.

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 may appeal to people interested in traditional herbal support, but evidence for its effectiveness isn't established in the data we hold. If you take blood thinners or antiplatelet medications, talk to your pharmacist before adding this supplement — even a mild blood-thinning effect can matter with those drugs.

Avoid it during pregnancy and breastfeeding.

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.

The safety data advise against mullein during pregnancy because there isn't enough information to know it's safe. Talk with your doctor or pharmacist about what to use instead.
Can I take this while breastfeeding?
No — there isn't enough data to consider it safe while breastfeeding. Please discuss with your pharmacist or doctor.
