Wood Anemone + Acalabrutinib

Acalabrutinib brand name: Calquence.

No Known Interaction
Medically reviewed by · Updated July 2026 · Pair last verified Sep 27, 2026
The bottom line No known interaction

We found no known interaction between Wood Anemone and Acalabrutinib 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 two are separately associated with some of the same side effects, which would make a new symptom harder to attribute to one or the other.

Wood Anemone and Acalabrutinib

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 Acalabrutinib 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 Acalabrutinib, 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.

No Interaction Found — But Data Suggests Wood Anemone and Acalabrutinib May Share a Side Effect

This is not an interaction. Neither one changes how your body handles the other, and nothing here says they react together. What our sources do show is that each has separately been linked to the effects below — so taking both can make those effects more likely to turn up, and harder to pin on one or the other if they do.

From our pharmacist’s overview on the Acalabrutinib page

“For anyone taking acalabrutinib (Calquence) for chronic lymphocytic leukemia or lymphoma, the supplement list below deserves genuine scrutiny. Of 144 ingredients on file, nearly all act on CYP3A4, the liver enzyme that clears the drug, or on P-glycoprotein, a transporter that moves it, so they can push its level too high or leave too l…”

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 Acalabrutinib

What Is Acalabrutinib Used For?

Brand name: Calquence

Calquence is used to treat adults with mantle cell lymphoma (MCL) — either newly diagnosed (in combination with bendamustine and rituximab, for patients who are not candidates for a stem cell transplant) or previously treated (after at least one prior therapy). It is also used to treat adults with chronic lymphocytic leukemia (CLL) or small lymphocytic lymphoma (SLL).

Both the capsule and tablet forms of Calquence are approved for all three of these uses. The specific combination regimen and treatment schedule depend on the condition being treated and what other medicines are used alongside it — your care team will map that out for you.
