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

We found no known interaction between Boxwood and Etomidate 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.

Boxwood and Etomidate

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 Etomidate and Boxwood 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.

How we checked

Why No Interaction Is Listed for Etomidate

Interactions in our licensed database are recorded against drug classes, not just single drug names. Etomidate is filed under a single classification — anesthesia. Boxwood has documented interactions with 2 drug classes — the most serious being anticholinergic drugs (moderate) and cholinergic drugs (moderate) — and none of Etomidate’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 Boxwood and Etomidate 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.

  • Vomiting Additional detail

    Boxwood

    “Orally, boxwood leaf extract seems to be well tolerated. However, ingestion of whole boxwood leaf can cause serious side effects including vomiting, diarrhea, severe colonic spasms, paralysis, and death secondary to asphyxiation (18).

    Topically, the fresh plant and wood can cause allergic contact dermatitis (18, 37073).

    When inhaled, the wood dust can cause rhinoconjunctivitis and bronchitis.”

Everything else you take

See Every Supplement That Interacts With Etomidate

This page covers Boxwood only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Etomidate page lists 5 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Fever Bark (major), Cannabis (moderate), Cowhage (moderate), Datura Wrightii (moderate) and Delta-9-tetrahydrocannabinol (thc) (moderate).

By severity: 1 major · 4 moderate.

From our pharmacist’s overview on the Etomidate page

“Etomidate is not a pill you take at home. It is an intravenous drug used to put you under quickly for surgery or emergency procedures, and that shapes what this short list of five interacting supplements means.”

About Boxwood

What is Boxwood?

Boxwood
  • HIV/immune support
  • Malaria
  • Arthritis
  • Diabetes
  • Skin conditions
  • Fever

Boxwood is an evergreen shrub whose leaves have been used in folk medicine, most notably in some early studies looking at HIV. The whole plant is toxic, so only processed extracts are used, and solid evidence for any health benefit is very limited. Because of real safety concerns, talk with a pharmacist or doctor before trying boxwood.

Buxus sempervirens · Buxaceae · Leaves (processed into extracts) · Capsules, liquid extracts, tinctures

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

Boxwood: dosing

There is no well-established or standardized dose of boxwood for any condition. The strength and quality of commercial extracts can vary a lot from product to product.If you choose to use a boxwood product, follow the directions on the label and do not exceed them. Never use leaves or material from garden boxwood, since the raw plant is toxic.

About Etomidate

What Is Etomidate Used For?

Brand name: Amidate

Etomidate — available as Amidate and under the generic name Etomidate — is given by intravenous (IV) injection to induce general anesthesia before surgery or other procedures. It brings on unconsciousness rapidly, usually within about one minute.

Amidate and etomidate injection products are also used to supplement weaker anesthetic agents, such as nitrous oxide in oxygen, during short operative procedures — for example, dilation and curettage (D&C) or cervical conization. This supplemental use is supported only for adult patients in short procedures; it is not recommended for longer procedures or for pediatric patients.

Taking Boxwood and Etomidate Together: Common Questions

Is it safe to take Boxwood with Etomidate?
We do not list a known interaction between Boxwood and Etomidate. 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.
Do Boxwood and Etomidate have any of the same side effects?
Yes — our sources link each of them separately to one of the same effects. That is not an interaction: neither changes how your body handles the other. It does mean that if one of those effects turns up, it can be harder to tell which one is behind it. They are listed on this page with the source behind each.
How was the Boxwood and Etomidate combination checked?
Interactions in our licensed database are recorded against drug classes. Etomidate is filed under 1 classification, and Boxwood has documented interactions with 2 drug classes — none of Etomidate's classifications are among them. A medication can belong to classes beyond those recorded in our dataset, so this describes how the check was run rather than guaranteeing safety.
Does Boxwood interact with any other medications?
Yes. Boxwood has 219 documented drug interactions in our database — Etomidate is simply not one of them. If you take anything else, it is worth checking each one; they are all listed on this page.
Does Etomidate interact with any supplements?
Yes. Etomidate has documented interactions with 5 supplements in our database — Boxwood is not one of them. The Etomidate interaction page linked on this page lists every one, ranked by severity.
