The bottom line No known interaction

We found no known interaction between Marshmallow and Adalimumab in our sources. Absence of a documented interaction is not the same as proven safety, and does not guarantee one does not exist.

Marshmallow and Adalimumab

We checked these two against our interaction database. Here is what we found.

No Known Interaction Found

We did not find a documented interaction between Adalimumab and Marshmallow in our sources. This does not guarantee that the combination is completely free of risk — there is often limited research on supplements and herbal products, especially around drug interactions.

If you decide to take both, the practical routine is simple: add one new thing at a time and note the date you started it. If the combination is going to disagree with you, it usually shows in the first days to a couple of weeks — and a start date turns “I’ve been feeling off” into something a pharmacist can actually work with. Do not stop a prescribed medicine on your own.

Always talk with your pharmacist or doctor before making changes to your medications or supplements, particularly if you take several medications or have an ongoing health condition.

Marshmallow safety at a glance

Marshmallow overall Use caution Generally well tolerated for short-term use, but human safety data are limited.
Pregnancy Avoid Not enough reliable safety information, so it is best avoided during pregnancy.
Breastfeeding Avoid Not enough reliable safety information, so it is best avoided while breastfeeding.

Safety guidance is general; always confirm with your pharmacist or doctor for your situation.

How we checked

Why No Interaction Is Listed for Adalimumab

Interactions in our licensed database are recorded against drug classes, not just single drug names. Adalimumab is filed under a single classification — immunosuppressants. Marshmallow has documented interactions with 3 drug classes — the most serious being lithium (moderate), anticoagulant/antiplatelet drugs (minor) and oral drugs (minor) — and none of Adalimumab’s classifications are among them.

Classification data comes from our licensed Natural Medicines dataset. A medication can belong to classes beyond those recorded there, so this describes how the check was run — it is not a safety guarantee.

Overlapping uses

What Adalimumab Is Prescribed For, and What Marshmallow Has Been Studied For

These two come up together because they touch the same health topic — not because they do the same job. Adalimumab is a prescription medicine with approved uses on its FDA label. Marshmallow is a supplement: what follows is what researchers have looked at it for, and how strong that evidence is.

Adalimumab is prescribed for: Adalimumab injection treats a range of moderate-to-severe inflammatory conditions in adults and some children. These include rheumatoid arthritis, psoriatic arthritis, ankylosing spondylitis, Crohn's disease, ulcerative colitis, plaque psoriasis, hidradenitis suppurativa (a chronic skin condition), and non-infectious uveitis (inflammation inside the eye). It is also approved to treat polyarticular juvenile idiopathic arthritis in patients as young as 2 years old, and Crohn's disease in children 6 years and older. Yuflyma is additionally approved for non-infectious uveitis in pediatric patients 2 years and older, and for hidradenitis suppurativa in patients 12 years and older.

Not every brand or formulation is approved for every condition listed — your prescriber will match the right product to your specific diagnosis.

Marshmallow has been studied for:

  • Diarrhea studied, not established Marshmallow has been studied for this. Natural Medicines rates the evidence: Insufficient Reliable Evidence To Rate Read what the research shows

    Marshmallow for diarrhea

    Although there is interest in using oral marshmallow for diarrhea, there is insufficient reliable information about the clinical effects of marshmallow for this condition.

Effectiveness ratings and the research summaries above are the verbatim record from the Natural Medicines database, which grades evidence from “Effective” down to “Insufficient Reliable Evidence To Rate”. A rating below the top of that scale means researchers have looked at it — not that it works, and never that it can stand in for a prescribed medicine. Do not stop or replace Adalimumab on your own; if you are taking Marshmallow for the same health topic, tell your prescriber, especially if the medicine is being adjusted to a target.

Everything else you take

See Every Supplement That Interacts With Adalimumab

This page covers Marshmallow only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Adalimumab page lists 53 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Active Hexose Correlated Compound (ahcc) (moderate), Alfalfa (moderate), American Ginseng (moderate), Andrographis (moderate) and Ashwagandha (moderate).

By severity: 52 moderate · 1 minor.

From our pharmacist’s overview on the Adalimumab page

“Adalimumab (Humira) works by dialing down an overactive immune system, which is what makes this list so uniform: all 53 supplements on file are flagged for one reason, they may stimulate immunity and could, in theory, blunt the drug's effect. None of the interactions is rated major (52 are moderate, one minor), so for most people this…”

About Marshmallow

What is Marshmallow?

Marshmallow
  • Cough and sore throat
  • Dry mouth and throat irritation
  • Digestive upset and heartburn
  • Skin irritation
  • Soothing inflamed tissue

Marshmallow root is a traditional herb rich in soothing, gel-like fibers called mucilage, which is why it has long been used for coughs, sore throats, and stomach irritation. Evidence for these uses is mostly traditional and preliminary, but it is generally considered gentle and well-tolerated for short-term use. As with any supplement, check with your pharmacist or doctor before using it, especially if you are pregnant, breastfeeding, or taking other medicines.

Althaea officinalis · Malvaceae · Root and leaves · Tea, capsules, tinctures, syrups, lozenges, dried root, topical creams

An interaction check asks whether these two react with each other — it does not ask whether Marshmallow is a good idea for someone in your situation. Here is what our Marshmallow record says about it on its own.

Marshmallow: dosing

There is no official, standardized dose for marshmallow. The right amount depends on the form (tea, capsule, syrup, lozenge, or tincture) and the specific product.The safest approach is to follow the directions on the product label and not exceed the recommended amount. For teas, the dried root is often steeped in water; for other forms, the manufacturer's instructions should guide you.When taking marshmallow as a capsule or tincture, it is often recommended to drink plenty of water.

Taking Marshmallow and Adalimumab Together: Common Questions

Is it safe to take Marshmallow with Adalimumab?
We do not list a known interaction between Marshmallow and Adalimumab. That does not guarantee the combination is risk-free, so confirm with your pharmacist or doctor — especially if you take other medications or have a health condition.
Are Marshmallow and Adalimumab used for the same thing?
They overlap in purpose, which usually means the real question is whether you need both rather than whether they are safe together. This page lists the shared uses and how strong the evidence is for Marshmallow in each. That is a conversation for your prescriber, especially if Adalimumab is being adjusted to a target.
How was the Marshmallow and Adalimumab combination checked?
Interactions in our licensed database are recorded against drug classes. Adalimumab is filed under 1 classification, and Marshmallow has documented interactions with 3 drug classes — none of Adalimumab's classifications are among them. A medication can belong to classes beyond those recorded in our dataset, so this describes how the check was run rather than guaranteeing safety.
Does Marshmallow interact with any other medications?
Yes. Marshmallow has 2,040 documented drug interactions in our database — Adalimumab is simply not one of them. If you take anything else, it is worth checking each one; they are all listed on this page.
Does Adalimumab interact with any supplements?
Yes. Adalimumab has documented interactions with 53 supplements in our database — Marshmallow is not one of them. The Adalimumab interaction page linked on this page lists every one, ranked by severity.
