HelloPharmacist Scorecard of Marshmallow Root by Botanic Choice

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 20, 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 liquid contains one active ingredient: marshmallow extract, made from the root of the marshmallow plant. The product also holds two inactive ingredients — glycerin and water — that help dissolve and preserve the 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.

We don't have reliable evidence in our data to confirm whether marshmallow root works for any of the conditions it's marketed for, including vaginal yeast infections, diarrhea, venous leg ulcers, eczema, or respiratory tract infections. The evidence is simply too limited right now to rate its effectiveness.

The evidence, ingredient by ingredient Marshmallow

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 root is generally well tolerated for short-term use, but human safety data are limited, so we don't know much about longer-term use. The safety information on file advises against it during pregnancy and while breastfeeding because there isn't enough data to know it's safe in those situations.

If you're pregnant, planning to become pregnant, or breastfeeding, talk with your doctor or pharmacist before taking this product.

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 take this product, check with your doctor or pharmacist if you're on lithium — the dose may need to be adjusted. If you take any oral medications, space them 30–60 minutes apart from this liquid.

If you're on blood thinners or antiplatelet drugs, mention this product to your healthcare provider.

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.

Marshmallow Root Liquid is generally well tolerated for brief use, but it does interact with lithium and may slow how you absorb other oral medications. If you take lithium, blood thinners, or other medications by mouth, check with your doctor or pharmacist before starting — and avoid it during pregnancy and breastfeeding without talking to your healthcare provider first.

For each ingredient in Marshmallow Root with known interactions, here are the types of medications it can affect. Open any type for the detail — or search your exact drug in the checker above.

Marshmallow 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 Root by Botanic Choice: Common Questions

Does Marshmallow Root by Botanic Choice interact with any medications?
Yes. Based on its ingredients, Marshmallow Root 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 Root 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 pregnant or breastfeeding?
The safety data advise against it. There isn't enough information to know whether it's safe in pregnancy or while breastfeeding. Talk with your doctor or pharmacist about whether it's right for you in those situations.
Will this help my sore throat or cough?
Marshmallow root is used for respiratory tract infections, but we don't have reliable evidence in our data to confirm it actually works for that. The evidence is too limited to rate it.
How should I take this with my other medications?
If you take oral medications, take this product 30–60 minutes after them to avoid the mucilage in marshmallow slowing their absorption. If you take lithium or blood thinners, talk with your doctor or pharmacist before starting.
Are there any side effects?
We don't have adverse-effect data on file, but marshmallow root is generally well tolerated for short-term use. Human safety data are limited, so longer-term effects aren't well studied.
What is marshmallow extract, and why is it in this product?
It's an extract made from the marshmallow plant's root. Traditionally it's used to soothe digestive and respiratory symptoms, though we don't have reliable evidence that it works for specific conditions.
