HelloPharmacist Scorecard of Organic Mullein Leaf by Ra 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 Aug 27, 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.

This product contains one active ingredient: mullein, a plant used traditionally to support respiratory health. The liquid form is made with cane alcohol and distilled water.

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. We have no reliable evidence to rate it for bronchitis, asthma, migraine headache, cough, or diarrhea — which means studies either haven't been done, are too small or low-quality to draw conclusions from, or are mixed.

If you're thinking about it for one of these reasons, it's worth talking it over with your doctor to see whether there's enough reason to try it.

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, but human safety data are limited. One concern: two people who had skin contact with the whole plant or breathed in plant dust developed dermatitis (skin irritation), confirmed by patch testing; one of those people also reacted to other plants.

If you have sensitive skin or a history of plant allergies, watch for any rash or irritation. For pregnancy and breastfeeding, the safety data advise against it.

There isn't enough information to know either way, so talk with your doctor or pharmacist about whether it's right for you 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 such as warfarin, aspirin, or clopidogrel), check your specific medications with the tool on this page and confirm with your own doctor or pharmacist before starting mullein. Lab evidence shows it can lengthen clotting time, which could add to your medication's effect.

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 respiratory herb, but we don't have reliable evidence it works for the conditions it's used for. The main concern is a minor blood-thinning effect if you're on anticoagulants or antiplatelets — check your exact medications before starting.

If you have sensitive skin or are pregnant or breastfeeding, talk it over with your doctor or pharmacist first.

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.

Organic Mullein Leaf by Ra Herbals: Common Questions

Does Organic Mullein Leaf by Ra Herbals interact with any medications?
Yes. Based on its ingredients, Organic Mullein Leaf 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?
Organic Mullein Leaf 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 — there isn't enough information to know whether it's safe. Talk with your doctor or pharmacist about your personal situation to decide what's right for you.
Does mullein actually work for cough or bronchitis?
We don't have reliable evidence to say whether it works for either one. Studies are either missing, too small, or mixed, so we can't rate it yet. Your doctor can help you weigh whether it's worth trying.
Are there side effects?
It's generally well tolerated for short-term use, but human data are limited. Two case reports describe skin irritation after direct contact with the plant or breathing in plant dust. If you have sensitive skin or plant allergies, watch for any rash.
Why does this interact with blood thinners?
Lab tests show mullein extracts can lengthen the time it takes blood to clot — likely because of compounds called triterpenoid saponins. If your medication already thins your blood, mullein's effect could add to it, so you'll want to check with your doctor first.
Is this product safe for long-term use?
The data show it's generally well tolerated for short-term use, but we don't have enough human safety information to know about long-term use. If you're thinking of taking it regularly, ask your doctor or pharmacist.
