Marsh Marigold + Omalizumab
Omalizumab brand name: Xolair.
We found no known interaction between Marsh Marigold and Omalizumab in our sources. Absence of a documented interaction is not the same as proven safety, and does not guarantee one does not exist. Do not start, stop, or change a medication or supplement based on this page; confirm with your pharmacist or doctor first.
Marsh Marigold and Omalizumab
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 Omalizumab and Marsh Marigold 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.
Worth understanding: our licensed dataset holds no drug-interaction record for Marsh Marigold at all — not against Omalizumab, and not against any other medication we track. This verdict therefore rests on the absence of any recorded data, not on research that looked at this combination and found nothing. We cannot rule an interaction out.
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.

From our pharmacist’s overview on the Omalizumab page
“None of the 53 supplements on file for omalizumab (Xolair) carries a major rating, so this is a list to read with steady attention rather than alarm. Xolair treats allergic asthma and chronic hives by calming part of the immune system, and every entry here pulls the other way: these are immune-stimulating products, echinacea and astrag…”

About Marsh Marigold
What is Marsh Marigold?
- Skin conditions and warts
- Cough and bronchitis (folk use)
- Painful or irregular menstruation (folk use)
- Constipation (folk use)
- Joint and rheumatic complaints (folk use)
Marsh Marigold is a wetland plant in the buttercup family that has been used in traditional and homeopathic medicine, but there is essentially no reliable human evidence that it works for any condition. The raw plant contains irritant compounds and is considered toxic when eaten fresh, so it is generally not recommended as a supplement.
Caltha palustris · Ranunculaceae · Flowers, leaves, and roots (mainly in folk medicine) · Tinctures, homeopathic preparations, dried herb; rarely used today
An interaction check asks whether these two react with each other — it does not ask whether Marsh Marigold is a good idea for someone in your situation. Here is what our Marsh Marigold record says about it on its own.
Marsh Marigold: dosing
There is no established or standardized dose for Marsh Marigold, and no recognized safe amount for everyday use. When in doubt, it is safest not to use this plant at all.

About Omalizumab Injection
What Is Omalizumab Injection Used For?
Brand name: Xolair
Xolair is used for several allergy-driven conditions. It treats moderate to severe persistent asthma in adults and children 6 and older whose symptoms aren't controlled by inhaled steroids alone and who test positive for a year-round airborne allergen. It is also used as an add-on maintenance treatment for chronic rhinosinusitis with nasal polyps (ongoing sinus inflammation with polyp growths) in adults 18 and older who haven't responded well to nasal corticosteroids.
Xolair is also approved to reduce allergic reactions — including anaphylaxis — from accidental food exposure in adults and children aged 1 and older with IgE-mediated food allergy. It must be used alongside strict food avoidance, and it is not a substitute for emergency treatment like epinephrine. Finally, Xolair treats chronic spontaneous urticaria (persistent hives with no identified trigger) in adults and adolescents 12 and older who still have symptoms despite antihistamine treatment.
