HelloPharmacist Scorecard of Marshmallow Leaf 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.

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: marshmallow leaf glycerite liquid extract. A glycerite is an herbal extract made by soaking the plant material in glycerin, which preserves the plant compounds and makes the supplement easier to take as a liquid.

The only other ingredient is glycerin itself, which is the solvent that carries the marshmallow extract.

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 is effective for any condition. The data available show insufficient reliable evidence to rate it for vaginal yeast infections, diarrhea, leg ulcers, eczema, or respiratory tract infections.

That doesn't mean it doesn't work — it means well-designed human studies haven't yet proven its benefit for these uses.

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 we don't know how it performs with longer-term or repeated use. During pregnancy and while breastfeeding, there isn't enough reliable safety information, so the data advise against it.

If you're pregnant, planning to become pregnant, or breastfeeding, talk with your doctor or pharmacist about whether this product is right for you.

Side effects, ingredient by ingredient Marshmallow

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.

Before you start this product, check with your doctor or pharmacist if you take lithium — marshmallow may increase its levels in your blood. Also double-check any oral medications you take regularly: you'll want to space marshmallow doses 30 to 60 minutes apart from them to avoid lowering their absorption.

If you're on a blood thinner like warfarin or aspirin, mention this product to your provider as well.

Check your own medication Run your meds through the checker above

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.

TerraVita Marshmallow Leaf is a single-ingredient supplement whose long-term safety and effectiveness haven't been well established. It does interact with lithium and can affect how your body absorbs other oral medications, and anyone on those drugs should check with their own doctor or pharmacist first.

If you're pregnant or breastfeeding, the safety data advise against it — discuss it with your healthcare provider.

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.

Marshmallow Leaf by TerraVita: Common Questions

Does Marshmallow Leaf by TerraVita interact with any medications?
Yes. Based on its ingredients, Marshmallow Leaf 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 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 if I'm on lithium?
Not without checking with your doctor first. Marshmallow may reduce how your kidneys clear lithium, raising its levels in your blood and risking toxicity. Your prescriber may need to adjust your lithium dose if you add this product.
Will this interfere with my other pills?
Possibly. Marshmallow contains mucilage, which can slow down how your stomach and intestines absorb oral medications. Space out your doses by taking marshmallow at least 30 to 60 minutes after your other medications to minimize the effect.
Is marshmallow leaf effective for anything?
The evidence we hold doesn't establish that it works for vaginal yeast infections, diarrhea, leg ulcers, eczema, or respiratory tract infections. Insufficient reliable evidence exists to rate it for any of these uses.
Is it safe to take long-term?
Marshmallow leaf is generally well tolerated for short-term use, but human safety data are limited. We don't have solid information on long-term safety, so it's worth discussing a timeline with your pharmacist or doctor.
Can I take it while pregnant or breastfeeding?
The safety data advise against it — there isn't enough reliable information. Talk with your doctor or pharmacist for personalized advice if you're pregnant, planning pregnancy, or breastfeeding.
