Butcher's Broom + Abemaciclib

Abemaciclib brand name: Verzenio.

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 Butcher's Broom and Abemaciclib 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.

Butcher's Broom and Abemaciclib

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 Abemaciclib and Butcher's Broom 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.

Butcher's Broom safety at a glance

Butcher's Broom overall Use caution Generally well tolerated short-term in most healthy adults, but evidence on long-term safety is limited.
Pregnancy Avoid Safety has not been established, so it is best avoided during pregnancy.

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

How we checked

Why No Interaction Is Listed for Abemaciclib

Interactions in our licensed database are recorded against drug classes, not just single drug names. Abemaciclib is filed under 2 classifications — cytochrome p450 3a4 (cyp3a4) substrates, oral drugs. Butcher's Broom has documented interactions with 2 drug classes — the most serious being alpha-adrenergic agonists (moderate) and alpha-adrenergic antagonists (moderate) — and none of Abemaciclib’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.

No Interaction Found — But Data Suggests Butcher's Broom and Abemaciclib May Share Several of the Same Side Effects

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.

  • Diarrhea / Vomiting / Nausea Additional detail

From our pharmacist’s overview on the Abemaciclib page

“A daily pill for a common form of advanced breast cancer, abemaciclib (Verzenio) only helps when its blood level stays steady, so this list of 138 supplements deserves genuine care. Nearly all of them act on CYP3A4, the liver enzyme that clears abemaciclib, meaning a supplement can push its level up and intensify side effects, or drag…”

About Butcher's Broom

What is Butcher's Broom?

Butcher's Broom
  • Chronic venous insufficiency
  • Varicose veins
  • Leg swelling and heaviness
  • Hemorrhoids
  • Circulation problems

Butcher's broom is a plant extract most often used for circulation problems in the legs, such as chronic venous insufficiency, where some evidence suggests it may help reduce swelling and discomfort. Quality and dosing vary widely between products, and it should not replace proven treatments. Talk with your pharmacist or doctor before starting it, especially if you are pregnant, breastfeeding, or have a health condition.

Ruscus aculeatus · Asparagaceae · Rhizome (underground stem) and roots · Capsules, tablets, extracts, teas, and topical creams or ointments

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

Butcher's Broom: dosing

There is no single official or standardized dose of butcher's broom. Products vary widely in their strength, how they are made, and whether they include other ingredients, which makes it hard to compare them.Many extracts are standardized to a certain amount of ruscogenins, but the right amount depends on the specific product.

About Abemaciclib

What Is Abemaciclib Used For?

Brand name: Verzenio

Verzenio (abemaciclib) is used to treat HR-positive, HER2-negative breast cancer in adults. For early breast cancer at high risk of recurrence, Verzenio is taken alongside endocrine therapy (tamoxifen or an aromatase inhibitor) after surgery to help prevent the cancer from coming back.

For advanced or metastatic breast cancer (cancer that has spread), Verzenio can be used in combination with an aromatase inhibitor as a first hormonal treatment, in combination with fulvestrant after the cancer has progressed on endocrine therapy, or alone after prior endocrine therapy and chemotherapy have stopped working.

Abemaciclib is filed under 2 classifications, and Butcher's Broom has documented interactions with 2 drug classes — none of Abemaciclib's classifications are among them.
