HelloPharmacist Scorecard of Mullein Leaf Chocolate Flavor by TerraVita

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 glycerite liquid extract. Mullein is a plant traditionally used for respiratory and cough support.

The extract is dissolved in glycerin and flavored with chocolate. That's it — the two other ingredients you'll see are the glycerin itself (which carries the extract) and the chocolate flavor.

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 relief.
  • 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 for mullein in treating bronchitis, asthma, cough, diarrhea, and migraine headache is not established in our data. We hold insufficient reliable evidence to rate whether it works for any of these uses.

If you're thinking about it for a specific condition, talking with your doctor or pharmacist can help you decide whether to try it alongside other care.

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 when used short-term, but human safety data are limited — we don't have a lot of information on longer-term use. The safety data advises against mullein during pregnancy and while breastfeeding.

A small number of people have reported dermatitis (skin inflammation) after touching the plant or breathing in plant dust, and some of these individuals also reacted to other plants, suggesting a possible sensitivity. Because safety information is incomplete, especially for pregnancy and lactation, talk with your doctor or pharmacist before using this product if you are pregnant, breastfeeding, or planning either.

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 any blood thinner or antiplatelet drug — such as warfarin, aspirin, clopidogrel, or others in that class — check with your doctor or pharmacist before starting mullein. The product has mild blood-thinning effects, and combining it with these medications could raise your bleeding risk.

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 is generally well tolerated for short-term use, but the evidence we hold doesn't establish whether it actually works for cough, bronchitis, asthma, or other common uses. If you take a blood thinner or antiplatelet drug, check with your doctor or pharmacist first — mullein has mild blood-thinning properties.

Avoid it during pregnancy and breastfeeding unless your healthcare provider says 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.

Mullein Leaf Chocolate Flavor by TerraVita: Common Questions

Does Mullein Leaf Chocolate Flavor by TerraVita interact with any medications?
Yes. Based on its ingredients, Mullein Leaf Chocolate Flavor 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?
Mullein Leaf Chocolate Flavor 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 mullein during pregnancy and while breastfeeding because there isn't enough information to know it's safe. Talk with your doctor or pharmacist about whether it's right for you.
Does mullein actually help with cough?
We don't have reliable evidence that it does. The data we hold show insufficient evidence to rate mullein for cough, bronchitis, asthma, or other respiratory uses.
What are the side effects?
Mullein is generally well tolerated overall, but a small number of people have reported skin inflammation after touching the plant or breathing in plant dust. Human safety data are limited, so we don't have complete information on longer-term use.
Is this safe to use long-term?
We have limited human safety data, especially for longer-term use. It's considered well tolerated short-term, but we don't know much about safety beyond that. Talk with your doctor or pharmacist if you're thinking about using it regularly.
What is glycerin doing in the formula?
Glycerin is the carrier — it's what the mullein extract is dissolved in to make the liquid drinkable. It's an inactive ingredient.
