HelloPharmacist Scorecard of Mullein Leaf 350 mg by Christopher's Original Formulas

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 at 350 mg per capsule. The capsule itself is plant-derived.

Mullein is a traditional herbal remedy used for respiratory support, though the evidence for its effectiveness is not yet established in our data.

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 supporting mullein for bronchitis, asthma, migraine headache, cough, or diarrhea is insufficient to rate. That doesn't mean it doesn't work — it means human studies haven't yet provided reliable proof 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. A small number of case reports have described skin irritation (dermatitis) after direct contact with the whole plant or inhalation of plant dust; in one case, the person also reacted to other plants.

Mullein is not recommended during pregnancy because there isn't enough safety information. The same applies to breastfeeding — there isn't enough data to consider it safe, so it's best avoided until you've talked with your doctor or pharmacist.

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.

Before taking this product, double-check with your doctor or pharmacist if you take anticoagulant or antiplatelet drugs (blood thinners such as warfarin, or antiplatelet medications). Mullein has mild blood-thinning effects that may combine with your medication.

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 Leaf may appeal to you if you're exploring traditional herbal support for cough or respiratory comfort, though scientific evidence for these uses hasn't been firmly established yet. If you take blood thinners or antiplatelet drugs, check with your doctor or pharmacist before starting — this product has mild blood-thinning properties and may add to that effect.

Avoid it during pregnancy or breastfeeding unless your own healthcare provider advises otherwise.

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.
