HelloPharmacist Scorecard of Plantain Combination Powder by TerraVita Premium Collection

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 Sep 3, 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 5 active ingredients.
  • “Proprietary Blend” is a proprietary blend — the label gives one combined amount (1,000 mg) without saying how much of each component you get.

This 5-ingredient powder contains white slippery elm, marshmallow, chamomile, rose hips, and plantain as active ingredients. Slippery elm is derived from the inner bark of the elm tree, while marshmallow is the root and leaf of that plant — both are traditional soothing herbs.

Rose hips provide vitamin C, and chamomile and plantain round out the blend. There are no other inactive ingredients listed.

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

The label doesn't state a purpose we can grade — see each ingredient's own graded uses on its monograph instead.

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 what this combination does isn't established in the data we hold. Slippery elm is studied for cough, constipation, diarrhea, and inflammatory bowel disease, but the evidence is insufficient to rate it for any of these.

Marshmallow is similarly studied for respiratory tract infections, eczema, venous leg ulcers, and diarrhea, with insufficient evidence for any. We have no effectiveness information on file for chamomile, rose hips, or plantain in this context.

The evidence, ingredient by ingredient Slippery Elm 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.

Slippery elm and marshmallow are generally well tolerated for short-term use, but high-quality long-term safety data are limited for both. Slippery elm pollen and its extracts can trigger contact dermatitis, rashes (urticaria), or allergic reactions in sensitive people.

On pregnancy and breastfeeding, the safety data are too thin: slippery elm sources advise caution in pregnancy and during breastfeeding due to lack of reliable information, while marshmallow's data advise against use during pregnancy and breastfeeding. Talk with your doctor or pharmacist about whether this product is right for you if you're pregnant or breastfeeding.

Side effects, ingredient by ingredient Slippery Elm 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, Slippery Elm.
  • 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 with your doctor or pharmacist before using this product if you take lithium — marshmallow may raise lithium levels and cause toxicity. Also confirm any oral medications (the mucilage can slow their absorption) or blood thinners, as marshmallow may have antiplatelet effects.

We could not check chamomile, rose hips, or plantain against drug interactions.

The bottom line

Scorecard at a glanceFormula with limited ingredient disclosure with no assessable stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

This powder blends five traditional soothing ingredients, but the clinical evidence that it works for any condition isn't strong in our data. If you take lithium, any oral medications, or blood thinners, you need to check with your doctor or pharmacist before adding it — the interactions are real.

If you're pregnant or breastfeeding, the safety information is too sparse; your healthcare provider can give you personalized advice.

Marshmallow, Powder3 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

Plantain Combination Powder by TerraVita Premium Collection: Common Questions

Does Plantain Combination Powder by TerraVita Premium Collection interact with any medications?
Yes. Based on its ingredients, Plantain Combination Powder 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?
Plantain Combination Powder contains 5 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.
Will this slow down my other medications?
Yes — slippery elm's mucilage can slow how your body absorbs oral drugs, and marshmallow does the same. If you take marshmallow, try separating it from your medications by 30 to 60 minutes to reduce the effect. Run your specific drugs through our checker or ask your pharmacist.
Is this safe if I take lithium?
Not without checking with your doctor first. Marshmallow's diuretic effects may cause your body to clear lithium more slowly, raising its level into the toxic range. Your prescriber may need to adjust your lithium dose if you use this product.
Can I take it while pregnant or breastfeeding?
There isn't enough safety data to know either way — slippery elm and marshmallow both have very limited pregnancy and breastfeeding information. Talk with your doctor or pharmacist for personalized advice before taking it.
What is slippery elm used for?
Slippery elm inner bark is a traditional soothing herb studied for cough, constipation, diarrhea, and inflammatory bowel disease. However, the evidence isn't strong enough yet to rate how well it actually works for any of these.
Could I have an allergic reaction to this?
Yes, especially to slippery elm. Its pollen is an allergen, and the bark extract can cause contact dermatitis or rashes (urticaria) in some people. Stop using it and call your doctor or pharmacist if you develop a rash or breathing trouble.
