Drug & supplement interaction

Khella + Desflurane

Desflurane brand name: Suprane.

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 Khella and Desflurane 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.

Khella and Desflurane

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 Desflurane and Khella 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 Desflurane

Interactions in our licensed database are recorded against drug classes, not just single drug names. Desflurane is filed under 2 classifications — anesthesia, oral drugs. Khella has documented interactions with 3 drug classes — the most serious being digoxin (lanoxin) (moderate), hepatotoxic drugs (moderate) and photosensitizing drugs (moderate) — and none of Desflurane’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 Khella and Desflurane 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.

In some patients, khella can cause elevated liver transaminase and gamma-glutamyltransferase (GGT) levels (2). There is also some concern that khella might cause photosensitivity (2,7162).”

Everything else you take

See Every Supplement That Interacts With Desflurane

This page covers Khella only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Desflurane page lists 22 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), Fever Bark (major), Cannabis (moderate), Coffee Charcoal (moderate) and Cowhage (moderate).

By severity: 2 major · 11 moderate · 9 minor.

From our pharmacist’s overview on the Desflurane page

“The interaction to understand first is fever bark with desflurane, the inhaled anesthetic that keeps patients asleep during surgery. Fever bark contains reserpine, tied to unstable heart function and blood pressure under general anesthesia, and it carries one of two major ratings among the 22 supplements on file.”

About Khella

What is Khella?

Khella
  • Asthma and bronchitis
  • Angina and heart-related chest pain
  • Kidney stones
  • Vitiligo and psoriasis
  • Mild high blood pressure

Khella is a Mediterranean herb whose seeds contain compounds like khellin that may relax smooth muscle in the airways and blood vessels. While it has a long history of traditional use for breathing and heart problems, modern evidence in supplement form is limited, and it can cause side effects and sun sensitivity, so talk with your pharmacist or doctor before using it.

Ammi visnaga · Apiaceae · Dried ripe fruit (seeds) · Capsules, tinctures, teas, standardized extracts

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

Khella: dosing

There is no well-established, standardized dose for khella supplements. The right amount depends on the product, how it is prepared, and the amount of active compounds it contains.Because strength varies widely between products, follow the directions on the label and do not exceed them. Avoid long-term use unless guided by a healthcare professional.

About Desflurane

What Is Desflurane Used For?

Brand name: Suprane

Desflurane (available as Desflurane USP and Suprane) is a general anesthetic given by inhalation during surgery. In adults, it is approved both to start (induce) anesthesia and to keep it going (maintain) throughout inpatient and outpatient procedures.

In infants and children, desflurane is approved only for maintaining anesthesia — and only after anesthesia has first been started with a different agent and the child has been intubated (a breathing tube placed). It is not approved to start anesthesia in children, and it must not be used to maintain anesthesia in children who are not intubated.

Taking Khella and Desflurane Together: Common Questions

Is it safe to take Khella with Desflurane?
We do not list a known interaction between Khella and Desflurane. 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 Khella and Desflurane have any of the same side effects?
Yes — our sources link each of them separately to 4 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 Khella and Desflurane combination checked?
Interactions in our licensed database are recorded against drug classes. Desflurane is filed under 2 classifications, and Khella has documented interactions with 3 drug classes — none of Desflurane'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 Khella interact with any other medications?
Yes. Khella has 618 documented drug interactions in our database — Desflurane 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 Desflurane interact with any supplements?
Yes. Desflurane has documented interactions with 22 supplements in our database — Khella is not one of them. The Desflurane interaction page linked on this page lists every one, ranked by severity.
