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

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 has one active ingredient: Marshmallow Leaf Glycerite Liquid Extract. A glycerite is an herbal extract made by soaking the plant material in glycerin, a natural preservative and sweetener.

The inactive ingredients are glycerin itself and vanilla flavor.

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 Marshmallow product and its label doesn't state a use — see Marshmallow'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 we hold doesn't establish that marshmallow leaf works for any of the conditions it's been studied for — vaginal yeast infections, diarrhea, leg ulcers, eczema, and respiratory tract infections all carry a rating of insufficient reliable evidence. That doesn't mean it doesn't work; it means the research isn't solid enough yet to say either way.

How safe is it?

Some data gaps
Safety Information · database check
Some gaps

Safety data exists for these ingredients, but with some important gaps.

Why this rating?
  • We hold adverse-effect (side-effect) data for 0 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.

Marshmallow leaf is generally well tolerated for short-term use, but human safety data are limited, so long-term use is less clear. There isn't enough reliable safety information to know whether it's safe during pregnancy or while breastfeeding — talk with your doctor or pharmacist for personalized advice if you're pregnant, planning pregnancy, or nursing.

No adverse effects were reported in the data we hold.

Meds to double-check

Moderate interaction found
Known Interaction Concern · database check
Moderate identified

The most serious documented interaction for these ingredients is Moderate. Check your medications for a personalized result.

Why this rating?
  • 1 of the 1 matched ingredient can interact with medications — Marshmallow.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; lithium.
  • For scale: 2,041 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 before taking if you use lithium — marshmallow may raise its level in your blood. Also mention it to your pharmacist or doctor if you take blood thinners or other oral medications, since marshmallow may interfere with how they're absorbed.

Take it 30 to 60 minutes after your other drugs to reduce this risk.

The bottom line

Scorecard at a glanceFully disclosed formula with no assessable stated purpose. Moderate medication interactions have been identified, and some safety-information gaps remain.

This product is best suited for people looking for a traditional herbal remedy for throat or digestive comfort when other options aren't working for them. If you take lithium, blood thinners, or other oral medications, check with your doctor or pharmacist before adding it — the interactions are real, though they're manageable with the right timing or dose adjustment.

Keep use short-term until you know how you tolerate it.

Marshmallow Leaf Glycerite Liquid Extract3 drug types · 2,040 drugs

Lithium

Theoretically, due to potential diuretic effects, marshmallow might reduce excretion and increase levels of lithium.
Marshmallow is thought to have diuretic properties. To avoid lithium toxicity, the dose of lithium might need to be decreased when used with marshmallow.

Likelihood Probable Evidence D
Anticoagulant/Antiplatelet Drugs

Theoretically, marshmallow flower might have antiplatelet effects.
Animal research suggests that marshmallow flower extract has antiplatelet effects. However, the root and leaf of marshmallow, not the flower, are the plant parts most commonly found in dietary supplements. Theoretically, use of marshmallow flower with anticoagulant/antiplatelet drugs can have additive effects, and might increase the risk for bleeding in some patients.

Likelihood Unlikely Evidence D
Oral Drugs

Theoretically, mucilage in marshmallow might impair absorption of oral drugs.
Marshmallow contains mucilage which can affect oral drug absorption. To avoid changes in absorption, take marshmallow 30-60 minutes after oral medications.

Likelihood Possible Evidence D

Marshmallow Leaf Vanilla Flavor by TerraVita: Common Questions

Does Marshmallow Leaf Vanilla Flavor by TerraVita interact with any medications?
Yes. Based on its ingredients, Marshmallow Leaf Vanilla Flavor has a known interaction with 2,040 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Marshmallow Leaf Vanilla 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 with my blood pressure or heart medications?
Marshmallow may slow absorption of oral medications — so yes, but time it carefully. Take this product 30 to 60 minutes after your other drugs to give them a head start. Still mention it to your pharmacist so they can confirm it won't interfere with your specific prescriptions.
Is this safe if I'm pregnant?
There isn't enough reliable safety data to know either way, so it's best avoided during pregnancy. Talk with your doctor or midwife about whether it's right for you and your situation.
Can I breastfeed while taking this?
The safety data aren't solid enough to say it's safe while nursing. Check with your doctor or pharmacist to decide whether it's okay for you and your baby.
Does marshmallow leaf actually work for colds or sore throats?
We don't have reliable evidence that it works for respiratory infections — the research just isn't strong enough to say yet. Some people use it as a traditional remedy, but if symptoms don't improve, see your doctor.
How long can I safely take this?
The data show it's generally well tolerated for short-term use, but human safety information is limited — we don't know much about long-term safety. Use it as directed on the label and check with your pharmacist if you want to take it longer than a few weeks.
What does a glycerite extract mean?
A glycerite is an herbal extract made by steeping the plant (in this case, marshmallow leaf) in glycerin, which acts as both a preservative and a sweetener. It's a common way to make liquid herbal supplements.
