HelloPharmacist Scorecard of Marshmallow Root 1000 mg by Double Wood Supplements

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 product contains one active ingredient: marshmallow root at 1,000 mg per capsule. Marshmallow is a plant whose root has been used traditionally to soothe irritated mucous membranes.

The capsule itself is made from hypromellose and microcrystalline cellulose, which are inactive ingredients that help hold the powder together.

Does it work?

Insufficient evidence
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
Insufficient

There isn't enough reliable clinical evidence to rate this product's ingredients for its stated purpose.

Why this rating?
  • The label markets this product for: digestive, respiratory, and skin health.
  • We looked for evidence on: Respiratory tract infections, Atopic dermatitis (eczema), sore throat, gastric irritation.
  • The closest evidence on file: Marshmallow is rated "Insufficient Reliable Evidence To Rate" for Respiratory tract infections (Natural Medicines).
  • Also on file: Marshmallow is rated "Insufficient Reliable Evidence To Rate" for Atopic dermatitis (eczema).

The evidence on marshmallow root isn't established in the data we hold. Our monograph lists several uses — vaginal yeast infections, diarrhea, venous leg ulcers, eczema, and respiratory tract infections — but for all of them, the reliable evidence to rate effectiveness is insufficient.

That doesn't mean it doesn't work; it means more research is needed to know how well it does.

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, though human safety data are limited. The safety data advise against use during pregnancy and breastfeeding because there isn't enough reliable information to know it's safe at those times.

If you're pregnant, nursing, or planning either, talk with your doctor or pharmacist before taking this supplement.

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.

Check before taking this product if you use lithium — marshmallow may increase its levels in your blood. Also, separate any other oral medications from marshmallow by at least 30 to 60 minutes to avoid absorption problems.

If you take blood thinners (anticoagulants) or antiplatelet drugs, mention marshmallow to your doctor or pharmacist as a precaution.

The bottom line

Scorecard at a glanceFully disclosed formula with insufficient evidence for its stated purpose. Moderate medication interactions have been identified, and some safety-information gaps remain.

Marshmallow root is a traditional botanical that's generally well tolerated short-term, but if you take lithium or multiple oral medications, you'll want to check with your own doctor or pharmacist first. Pregnancy and breastfeeding are times to avoid it unless your healthcare provider says otherwise.

It may help with certain conditions, but the research backing those uses isn't solid yet.

Marshmallow3 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 Root 1000 mg by Double Wood Supplements: Common Questions

Does Marshmallow Root 1000 mg by Double Wood Supplements interact with any medications?
Yes. Based on its ingredients, Marshmallow Root 1000 mg 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 1000 mg 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 Marshmallow Root if I'm pregnant or breastfeeding?
The safety data advise against it — there isn't enough reliable information about marshmallow during pregnancy or breastfeeding. Talk with your doctor or pharmacist about what's safe for you and your baby.
What is marshmallow root used for?
Marshmallow root has been used traditionally to soothe irritated mucous membranes and is linked in the literature to uses like vaginal yeast infections, diarrhea, eczema, and respiratory infections. However, reliable evidence to confirm how well it works for any of these isn't established in our data.
Does marshmallow root have side effects?
No adverse effects are documented in our data. However, human safety data are limited, and we only know it's generally well tolerated for short-term use.
How should I take this if I'm on other oral medications?
Take marshmallow at least 30 to 60 minutes after your other oral medications to avoid the mucilage in it from slowing their absorption.
I take lithium. Is this product safe for me?
You'll need to check with your doctor or pharmacist first. Marshmallow may reduce how much lithium your body clears, potentially raising its levels and causing toxicity — your dose might need adjustment.
