Drug & supplement interaction

Gardenia + Midazolam

Midazolam brand names: Versed, Seizalam, Nayzilam.

No Known Interaction

Medically reviewed by Dr. Brian Staiger, PharmD, BCPS · Updated July 2026 · Pair last verified Sep 20, 2026

The bottom line No known interaction

We found no known interaction between Gardenia and Midazolam 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.

Interaction report

Gardenia and Midazolam

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 Midazolam and Gardenia 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.

Gardenia safety at a glance

Gardenia overall Use caution Human safety data are limited, and large or long-term amounts have not been well studied.

Pregnancy Avoid Not enough safety information is available, so it is best to avoid it during pregnancy.

Breastfeeding Avoid There is not enough safety information, so avoid it while breastfeeding.

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

How we checked

Why No Interaction Is Listed for Midazolam

Interactions in our licensed database are recorded against drug classes, not just single drug names. Midazolam is filed under 6 classifications — including benzodiazepines, anesthesia, cns depressants. Gardenia has documented interactions with 1 drug class — the most serious being stimulant laxatives (moderate) — and none of Midazolam’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.

What to actually watch for

No Interaction Found — But Data Suggests Gardenia and Midazolam 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.

Vomiting / Nausea Additional detail

“Orally, there are case reports of mesenteric phlebosclerosis, a thickening of the walls of the intestine and mesenteric veins, which can lead to obstruction and occlusion. Typical presenting symptoms are paroxysmal abdominal pain with nausea and vomiting, and imaging studies reveal thickening and stiffening of the walls of the ascending and transverse colon, with dark purple discoloration of the colonic and rectal mu…”

Listed in the ADVERSE REACTIONS section of the FDA label for Midazolam. Read the label on DailyMed ›

Reported for Gardenia but not commonly for Midazolam: stomach pain and a skin rash.

Effects for Midazolam come from the ADVERSE REACTIONS section of its FDA label; effects for Gardenia come from the Natural Medicines adverse-effect record, quoted above. Where a percentage is shown, it is the share of 29,268 voluntary FDA FAERS reports for Midazolam that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Wording is matched across sources by our own clinical vocabulary, so treat this as a prompt to pay attention, not a diagnosis.

Overlapping uses

What Midazolam Is Prescribed For, and What Gardenia Has Been Studied For

These two come up together because they touch the same health topic — not because they do the same job. Midazolam is a prescription medicine with approved uses on its FDA label. Gardenia is a supplement: what follows is what researchers have looked at it for, and how strong that evidence is.

Midazolam is prescribed for: Midazolam is used in several different forms depending on the setting. Injectable midazolam (given by IV or IM shot) is used before and during surgery or procedures — such as endoscopy, cardiac catheterization, or bronchoscopy — to cause sedation, reduce anxiety, and prevent memory of the event. It can also be used to start general anesthesia or to keep heavily sedated, ventilated patients comfortable in a critical care unit. Midazolam HCl oral syrup is used specifically in children for sedation and anxiety relief before procedures or anesthesia induction, in a monitored medical setting only.

Read the rest of what Midazolam is prescribed for

Nayzilam nasal spray is indicated for a different purpose: the acute treatment of seizure clusters (also called acute repetitive seizures) in people aged 12 and older who have epilepsy. It is used intermittently — not as a daily seizure medicine — when a cluster of seizures breaks through the person's usual pattern.

Gardenia has been studied for:

Anxiety studied, not established Gardenia has been studied for this. Natural Medicines rates the evidence: Insufficient Reliable Evidence To Rate Read what the research shows

Gardenia for anxiety

Although there has been interest in using oral gardenia for anxiety, there is insufficient reliable information about the clinical effects of gardenia for this purpose.

Effectiveness ratings and the research summaries above are the verbatim record from the Natural Medicines database, which grades evidence from “Effective” down to “Insufficient Reliable Evidence To Rate”. A rating below the top of that scale means researchers have looked at it — not that it works, and never that it can stand in for a prescribed medicine. Do not stop or replace Midazolam on your own; if you are taking Gardenia for the same health topic, tell your prescriber, especially if the medicine is being adjusted to a target.

Everything else you take

See Every Supplement That Interacts With Midazolam

This page covers Gardenia only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Midazolam page lists 202 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: 1,4-butanediol (major), Activated Charcoal (major), Beer (major), Bitter Orange (major) and Fever Bark (major).

By severity: 11 major · 153 moderate · 38 minor.

From our pharmacist’s overview on the Midazolam page

“Sedation stacked on sedation is the headline risk with midazolam (Versed, Seizalam, Nayzilam). Midazolam is a benzodiazepine used for sedation and seizure emergencies, and 78 of the 202 interacting ingredients here, beer and wine included, add their own drowsiness, which can slide into dangerously slowed breathing.”

Anxiety, restlessness, and trouble sleeping
Blood pressure and blood sugar support (traditional)
Natural food and fabric coloring

Gardenia fruit has a long history in traditional Chinese medicine and is also used as a natural food coloring. While early lab and animal studies are interesting, strong human evidence for its health benefits is lacking, so talk with your pharmacist or doctor before using it as a supplement.

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

Gardenia: dosing

There is no standardized, well-established dose for gardenia supplements. Traditional formulas use the dried fruit in decoctions, but products sold today vary widely in strength and form.If you choose to use a gardenia product, follow the directions on the label and do not exceed the recommended amount.

Taking Gardenia and Midazolam Together: Common Questions

Is it safe to take Gardenia with Midazolam?

We do not list a known interaction between Gardenia and Midazolam. 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 Gardenia and Midazolam have any of the same side effects?

Yes — our sources link each of them separately to 2 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.

Are Gardenia and Midazolam used for the same thing?

They overlap in purpose, which usually means the real question is whether you need both rather than whether they are safe together. This page lists the shared uses and how strong the evidence is for Gardenia in each. That is a conversation for your prescriber, especially if Midazolam is being adjusted to a target.

How was the Gardenia and Midazolam combination checked?

Interactions in our licensed database are recorded against drug classes. Midazolam is filed under 6 classifications, and Gardenia has documented interactions with 1 drug class — none of Midazolam'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 Gardenia interact with any other medications?

Yes. Gardenia has 21 documented drug interactions in our database — Midazolam 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 Midazolam interact with any supplements?

Yes. Midazolam has documented interactions with 202 supplements in our database — Gardenia is not one of them. The Midazolam interaction page linked on this page lists every one, ranked by severity.
