HelloPharmacist Scorecard of Althaea Off. Marshmallow by Wise Woman Herbals

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 Jul 11, 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.
  • “Proprietary Blend” is a proprietary blend — the label gives one combined amount (3 mL) without saying how much of each component you get.

This product contains one active ingredient: marshmallow root and/or leaf extract. Marshmallow has a long history in herbal medicine, traditionally used to soothe mucous membranes in the throat and digestive tract.

The liquid also contains spring water and alcohol 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 for marshmallow isn't established yet in the data we hold. We don't have reliable evidence to rate how well it works for vaginal yeast infections, diarrhea, leg ulcers, eczema, or respiratory infections — conditions it's sometimes used for.

That doesn't mean it doesn't work; it means the clinical trials aren't there yet to say one way or the other.

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, though human safety studies are limited. There isn't enough reliable safety information to recommend it during pregnancy or while breastfeeding, so those aren't good times to use it.

No adverse effects are documented in the data we hold. If you're pregnant, nursing, or planning either, talk with your doctor or pharmacist before starting.

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, double-check if you take lithium — marshmallow may raise its level in your blood (Moderate concern). Also flag any blood thinners or antiplatelet drugs like aspirin, and any other oral medications, since the extract may affect how you absorb them (Minor concerns).

Use the checker on this page to run your exact prescriptions.

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.

This single-ingredient marshmallow extract is straightforward — it may help soothe irritated mucous membranes, but the evidence isn't solid yet. If you take lithium or any blood thinners, check with us first.

Pregnant or nursing? Skip it until you've talked with your healthcare provider.

For each ingredient in Althaea Off. Marshmallow 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.

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.

How can one product interact with so many drugs?
Althaea Off. Marshmallow 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?
There isn't enough reliable safety information about marshmallow in pregnancy or while nursing. It's best to avoid it during those times and talk with your doctor or pharmacist for personalized advice.
What is marshmallow actually used for?
Traditionally, marshmallow root and leaf have been used to soothe irritated mucous membranes in the throat and gut. The evidence to back that up isn't established yet in our data, though.
Does this product have any known side effects?
No adverse effects are documented in our data. The ingredient is generally well tolerated for short-term use, though human safety studies are limited.
Why do I need to wait 30–60 minutes after taking other medications?
Marshmallow contains a gummy substance called mucilage that can slow your stomach's absorption of oral drugs. Spacing them out prevents that interference.

The active ingredient is marshmallow (the root and/or leaf), and the inactive ingredients are spring water and alcohol. The 'proprietary blend' is just the way the marshmallow extract is packaged.
