Medically reviewed by · Updated July 2026 · Pair last verified Sep 20, 2026
The bottom line No known interaction

We found no known interaction between Wood Anemone and Trospium 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. Additionally, although there is no interaction, the label for Trospium states a food rule worth keeping to.

Wood Anemone and Trospium

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 Trospium and Wood Anemone 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 Wood Anemone at all — not against Trospium, 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.

What to actually watch for

What Wood Anemone Itself Has Been Linked To

This is not an interaction — nothing below involves Trospium. It is the side-effect record for Wood Anemone on its own, from the licensed Natural Medicines monograph. If something new turns up after you add Wood Anemone, this list is the first place to look.

  • Diarrhea Additional detail

    “Orally, the ingestion of freshly harvested wood anemone can cause colic, diarrhea, and severe irritation to the gastrointestinal tract and the urinary drainage passages (18).”

Everything above comes from the Natural Medicines adverse-effect record for Wood Anemone — expand a row for the licensed statement it rests on. We read the ADVERSE REACTIONS section of Trospium’s FDA label too, and the two lists don’t meaningfully overlap — which is why no Trospium column appears here.

How to take them

Some Trospium Products Have a Food Rule — Wood Anemone Should Not Break It

At least one FDA label for a product containing Trospium says to take it on an empty stomach. Most supplements — Wood Anemone included — are taken with a meal, so the easy mistake is swallowing both together at breakfast. Where that rule applies, keep Trospium on its own and move Wood Anemone to a meal later in the day.

This may not be true of your version. Food instructions belong to the product, not the ingredient: two Trospium products can carry different directions, and extended-release forms often differ from immediate-release ones. The label we read is quoted below — check the directions on your own box or bottle, or ask your pharmacist, for how to take the exact product you were given.

Trospium Chloride Extended-Release Capsules should be dosed with water on an empty stomach, at least one hour before a meal.

From the Dosage and Administration section of the FDA label we read for Trospium — where that label names a specific product, the instruction is that product's. See the Trospium drug page ›

A food rule is not an interaction — it is about how much of the medicine you absorb. The directions that came with your own product, and your pharmacist, outrank anything on this page.

From our pharmacist’s overview on the Trospium page

“Trospium (Sanctura, Regurin) calms an overactive bladder by blocking acetylcholine, and most of the 47 supplements flagged against it press on that same nerve signal. Thirty carry anticholinergic activity of their own, adding dry mouth, constipation, blurred vision, and confusion, and two of the three major ratings sit in that group: h…”

About Wood Anemone

What is Wood Anemone?

  • Headache and migraine (traditional)
  • Joint and muscle aches (traditional)
  • Skin conditions (traditional/topical)
  • Menstrual complaints (folk use)
  • Homeopathic remedy (Pulsatilla-type uses)

Wood Anemone is a spring woodland flower in the buttercup family that contains an irritant compound and is considered toxic when fresh. It has a history of folk and homeopathic use, but there is no good scientific evidence that it works for any condition, and it is not recommended as a self-care supplement.

Anemone nemorosa · Ranunculaceae · Aerial parts (leaves and flowers); historically the whole fresh plant · Rarely used today; historically as a fresh-plant tincture or homeopathic preparation

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

Wood Anemone: dosing

There is no established or recommended safe dose of Wood Anemone as a supplement. Do not prepare or take homemade products from the wild plant.

About Trospium

What Is Trospium Used For?

Brand names: Sanctura, Trosec, Regurin

Trospium — available as tablets and extended-release capsules — is used to treat overactive bladder (OAB). It targets three main symptoms: the sudden, hard-to-control urge to urinate (urgency), leaking urine when that urge hits (urge urinary incontinence), and needing to urinate much more often than usual (urinary frequency).

Both Trospium Chloride Tablets and Trospium Chloride Extended-Release Capsules carry this indication. Your prescriber will choose the formulation that fits your schedule and health history.

Taking Wood Anemone and Trospium Together: Common Questions

Is it safe to take Wood Anemone with Trospium?
We do not list a known interaction between Wood Anemone and Trospium. 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.
Should I take Wood Anemone and Trospium at the same time of day?
At least one FDA label for a product containing Trospium says to take it on an empty stomach, and supplements are usually taken with a meal — so taking them together at breakfast is the easy mistake. Where that applies, keep Trospium on its own and move Wood Anemone to a meal later in the day. Food instructions belong to the product rather than the ingredient, so check the directions on your own box. This is about absorption, not an interaction.
Does Trospium interact with any supplements?
Yes. Trospium has documented interactions with 47 supplements in our database — Wood Anemone is not one of them. The Trospium interaction page linked on this page lists every one, ranked by severity.
