HelloPharmacist Scorecard of Astragalus/Marshmallow by Herb Stop

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 16, 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 2 active ingredients.
  • “Proprietary Blend” is a proprietary blend — the label gives one combined amount (732 mg) without saying how much of each component you get.

This capsule contains 2 active ingredients in a proprietary blend: astragalus and marshmallow. Astragalus is a traditional herb sometimes used for immune and energy support, while marshmallow is traditionally valued for respiratory and digestive comfort.

The capsule also contains inactive ingredients — hydroxypropyl methylcellulose and purified water — which help deliver the herbs.

Does it work?

Not established
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 established

The graded evidence we hold for these ingredients covers different conditions than the ones this product is marketed for, so there's no established rating for its stated use.

Why this rating?
  • The label markets this product for: Supports healthy immune function.
  • We looked for evidence on: Respiratory tract infections, Upper respiratory tract infection (URTI), Chemotherapy-induced leukopenia, common cold, influenza, infection prevention.
  • The closest evidence on file: Marshmallow is rated "Insufficient Reliable Evidence To Rate" for Respiratory tract infections (Natural Medicines).
  • Also on file: Astragalus is rated "Insufficient Reliable Evidence To Rate" for Upper respiratory tract infection (URTI), Chemotherapy-induced leukopenia.

The evidence for both ingredients remains limited. For astragalus, we have insufficient reliable data to rate its effectiveness for allergic rhinitis (hay fever), amenorrhea, aplastic anemia, angina, asthma, or beta-thalassemia.

Similarly, marshmallow lacks sufficient reliable evidence for vaginal candidiasis, diarrhea, venous leg ulcers, atopic dermatitis (eczema), or respiratory tract infections. If you're considering this product for a specific condition, talk it through with your doctor or pharmacist — they can discuss whether the evidence supports its use in your case.

The evidence, ingredient by ingredient Astragalus Marshmallow

How safe is it?

Well-documented data
Safety Information · database check
Well characterized

Adverse-effect, pregnancy, and general safety data are on file for most of these ingredients.

Why this rating?
  • We hold adverse-effect (side-effect) data for 1 of the 2 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 2 of 2.
  • General safety write-ups exist for 2 of 2.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Both astragalus and marshmallow are generally well tolerated for short-term use in healthy adults, but human safety data are limited. Astragalus has occasionally been associated with dizziness, palpitations, and rash (especially when given intravenously in clinical settings), though a causal link hasn't been firmly established.

The safety data advise against using either ingredient during pregnancy or while breastfeeding because there isn't enough reliable information to know they're safe in those situations — talk with your doctor or pharmacist if you're pregnant, planning to become pregnant, or nursing.

Side effects, ingredient by ingredient Astragalus 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?
  • 2 of the 2 matched ingredients can interact with medications — Marshmallow, Astragalus.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; immunosuppressants / transplant drugs; diabetes medications; lithium.
  • For scale: 2,141 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 (moderate risk of toxicity), immunosuppressive drugs or cyclophosphamide (moderate risk of reduced effect), antidiabetes medications (moderate risk of low blood sugar), blood thinners or antiplatelet drugs (minor risk), or any other oral medications (minor risk of reduced absorption — space them 30–60 minutes apart from this product).

The bottom line

Scorecard at a glanceFormula with limited ingredient disclosure with no established evidence rating for its marketed use. Moderate medication interactions have been identified, and safety information is well characterized.

This product might interest someone looking for traditional immune or digestive support with minimal concern for side effects in the short term. However, if you take lithium, diabetes medications, immunosuppressants, chemotherapy drugs, or blood thinners, you'll need to check with your doctor or pharmacist first — the interactions are real enough to matter.

Pregnant and breastfeeding women should also discuss it with their healthcare provider before starting.

For each ingredient in Astragalus/Marshmallow with known interactions, here are the types of medications they 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.

Likelihood Possible Evidence D

Astragalus4 drug types · 208 drugs

Antidiabetes Drugs

Theoretically, taking astragalus with antidiabetes drugs might increase the risk of hypoglycemia.
Clinical research in humans shows that astragalus might have hypoglycemic effects. Theoretically, taking astragalus, especially in combination with other hypoglycemic agents, might increase the risk of hypoglycemia.

Likelihood Probable Evidence A
Cyclophosphamide

Theoretically, astragalus might interfere with cyclophosphamide therapy.
Evidence regarding the effect of astragalus on immunosuppression caused by cyclophosphamide is conflicting. Some animal research suggests that astragalus reverses cyclophosphamide-induced immunosuppression. However, other animal research shows no effect.

Likelihood Possible Evidence D
Immunosuppressants

Theoretically, astragalus might interfere with immunosuppressive therapy.
Astragalus seems to stimulate immune function. Theoretically, taking astragalus might decrease the effects of immunosuppressive therapy.

Likelihood Possible Evidence D
Lithium

Theoretically, astragalus might increase levels and adverse effects of lithium.
Animal research suggests that astragalus has diuretic properties. Theoretically, due to this diuretic effect, astragalus might reduce excretion and increase levels of lithium.

Astragalus/Marshmallow by Herb Stop: Common Questions

Does Astragalus/Marshmallow by Herb Stop interact with any medications?
Yes. Based on its ingredients, Astragalus/Marshmallow has a known interaction with 2,140 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Astragalus/Marshmallow contains 2 active ingredients, and an interaction can come from any of them. We check every ingredient, combine the results into one list per medication, and show which ingredient and mechanism is 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 while I'm pregnant or breastfeeding?
The safety data for both astragalus and marshmallow advise against use during pregnancy and breastfeeding because there isn't enough reliable information. Talk with your doctor or pharmacist about whether it's right for you.
Does astragalus really work for immune health?
The evidence isn't established in the data we hold. We lack sufficient reliable data to rate astragalus for the conditions it's traditionally used for — allergies, energy, anemia, heart health, and asthma. Your doctor can discuss whether it's appropriate for your needs.
What's in a capsule of this product?
Each capsule contains astragalus and marshmallow in a proprietary blend, plus hydroxypropyl methylcellulose and purified water to form the capsule. The exact amounts of each herb aren't listed on the label.
Is there a side effect I should watch for?
Both herbs are generally well tolerated short-term. Astragalus has occasionally caused dizziness or palpitations in clinical trials, though a direct link wasn't confirmed. Human safety data are limited, so if you notice any unusual symptoms, stop and talk to your pharmacist or doctor.
Why do I need to space this 30–60 minutes from my other pills?
Marshmallow contains a thick substance called mucilage that can slow how your body absorbs other oral medications. Taking them separately helps make sure your other drugs work as intended.
What is marshmallow in this supplement — is it the candy?
No. This marshmallow is the plant root and leaf, traditionally used for respiratory and digestive comfort. It's unrelated to the candy.
