Drug & supplement interaction

Wood Anemone + Voxelotor

Voxelotor brand name: Oxbryta.

No Known Interaction
Medically reviewed by · Updated July 2026 · Pair last verified Sep 13, 2026
The bottom line No known interaction

We found no known interaction between Wood Anemone and Voxelotor 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 Voxelotor

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 Voxelotor 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 Voxelotor, 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 Voxelotor 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 Voxelotor page

“Anyone taking voxelotor (Oxbryta) for sickle cell disease should treat this list with real care, because the pattern behind it is unusually consistent. Almost every entry works through CYP3A4, the same liver enzyme that clears voxelotor, so these ingredients can push the drug's blood level higher or pull it lower, either adding side ef…”

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

About Voxelotor

What Is Voxelotor Used For?

Brand name: Oxbryta

Oxbryta (voxelotor) is approved to treat sickle cell disease (SCD) in adults and in children as young as 4 years old. It works by targeting the underlying problem in sickle cell disease — the abnormal hemoglobin that causes red blood cells to take on a rigid, sickle shape.

This approval was granted under the FDA's accelerated approval pathway, based on the drug's ability to raise hemoglobin levels. Continued approval may depend on results from confirmatory clinical trials showing broader clinical benefit.

Most-Reported Side Effects for Voxelotor

From FAERS, the FDA’s public side-effect reporting system (22,300 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.

Sickle cell anaemia with crisis 11,218 reports
Diarrhea 3,187 reports
Nausea 2,016 reports
Headache 1,691 reports
Abdominal pain upper 1,171 reports
