HelloPharmacist Scorecard of Marshmellow by L.A. Naturals

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

Low disclosure
Ingredient Transparency · database check
Low

Most active ingredients don't disclose an individual amount — you can't tell how much of each you're getting.

Why this rating?
  • The label discloses an exact amount for 0 of its 1 active ingredient.

This product contains one active ingredient: certified organic fresh marshmallow (the root and leaf). Marshmallow is a plant used traditionally to soothe irritated tissues, particularly in the digestive tract and respiratory system.

The liquid also includes grain alcohol and deionized water as inactive ingredients.

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 is effective for any of the conditions it's used for — vaginal yeast infections, diarrhea, leg ulcers, eczema, or respiratory infections all fall short of reliable proof. That doesn't mean it doesn't work; it means larger, well-designed human studies haven't been done yet or the data we have isn't strong enough to say.

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 is generally well tolerated for short-term use, but human safety data are limited, so we don't know as much as we'd like about longer use. There isn't enough reliable information to know whether it's safe during pregnancy or while breastfeeding — the safety data advises against use in both.

Talk with your doctor or pharmacist if you're pregnant, nursing, or planning to be before you take it.

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 take lithium — the dose may need adjustment. Also double-check any oral medications you take by mouth (space this product 30 to 60 minutes away from them), and if you use blood thinners or antiplatelet drugs like warfarin or aspirin, make sure your prescriber knows you're considering marshmallow.

The bottom line

Scorecard at a glanceFormula with limited ingredient disclosure with no assessable stated purpose. Moderate medication interactions have been identified, and some safety-information gaps remain.

L.A. Naturals Marshmallow is a traditional herbal liquid with limited evidence for any specific condition and a need to watch for drug interactions, especially with lithium and oral medications generally.

If you take lithium, any blood thinners, or medications you take by mouth, check with your doctor or pharmacist before starting this — spacing and dosing matter. It's not recommended in pregnancy or while breastfeeding.

certified organic fresh 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.

Marshmellow by L.A. Naturals: Common Questions

Does Marshmellow by L.A. Naturals interact with any medications?
Yes. Based on its ingredients, Marshmellow 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?
Marshmellow 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.
Is marshmallow safe to use while pregnant or breastfeeding?
No — there isn't enough reliable safety information in the data we hold, so it's advised to avoid it during pregnancy and while breastfeeding. Talk with your doctor or pharmacist for personalized guidance.
How should I time this if I take other oral medications?
Take marshmallow 30 to 60 minutes after your oral medications. The mucilage in marshmallow can interfere with how your body absorbs drugs taken by mouth, so spacing the doses helps prevent that.
Does this product work for diarrhea, eczema, or respiratory infections?
The evidence we hold isn't strong enough to say it does. Marshmallow is used traditionally for these conditions, but larger human studies haven't established that it's effective for them.
What's in this liquid besides marshmallow?
The active ingredient is certified organic fresh marshmallow root and leaf. It also contains grain alcohol and deionized water as inactive ingredients.
Can I take this with lithium?
Only with your doctor's approval and oversight. Marshmallow's diuretic properties may slow how your body clears lithium, raising its level and risk of toxicity — your lithium dose may need to be lowered. Your prescriber needs to know you're taking this.
