Lemongrass and Semaglutide

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 Semaglutide and Lemongrass 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.

Lemongrass overall Use caution Likely safe in food amounts, but concentrated extracts and the essential oil have less safety data.
Pregnancy Likely Unsafe When used orally. Lemongrass seems to have uterine and menstrual flow stimulating effects; avoid using. Read the full pregnancy detail
Breastfeeding Use caution Not enough reliable data; avoid medicinal amounts and stick to occasional food use.

Pregnancy & breastfeeding ratings are from Natural Medicines (Therapeutic Research Center) — the full detail is in the Special populations card below. Safety guidance is general; always confirm with your pharmacist or doctor for your situation.

How we checked

Why No Interaction Is Listed for Semaglutide

Interactions in our licensed database are recorded against drug classes, not just single drug names. Semaglutide is filed under 2 classifications — antidiabetes drugs, oral drugs. Lemongrass has documented interactions with 3 drug classes — the most serious being cytochrome p450 3a4 (cyp3a4) substrates (moderate), glucuronidated drugs (moderate) and pentobarbital (nembutal) (moderate) — and none of Semaglutide’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 Semaglutide’s Own FDA Label Lists

This is not an interaction — none of it involves Lemongrass. These are the most notable effects listed in the ADVERSE REACTIONS section of Semaglutide’s own FDA label, for the medication by itself. Knowing the drug’s own list makes it easier to work out the likely cause if something new turns up while you take both. 5 of them are worth acting on rather than waiting out — marked below.

  • Low blood sugar Worth acting on
  • Pancreatitis Worth acting on
  • Kidney problems Worth acting on
  • Raised blood pressure Worth acting on
  • An allergic reaction Worth acting on
  • Heartburn
  • Bloating or gas
  • Hair loss
  • Drowsiness
  • Stomach upset

From the ADVERSE REACTIONS section of the FDA label for Semaglutide. Read the label on DailyMed › Lemongrass’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Lemongrass side to compare — that is a limit of the record, not a statement that Lemongrass has no side effects.

Overlapping uses

What Semaglutide Is Prescribed For, and What Lemongrass Has Been Studied For

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

Semaglutide is prescribed for: Semaglutide is used for several conditions, depending on the product. Wegovy is used with a reduced-calorie diet and more physical activity to reduce excess body weight and keep it off long term. It is also used to lower the risk of major cardiovascular events (heart-related death, non-fatal heart attack, or non-fatal stroke) in adults with established cardiovascular disease and either obesity or overweight. Wegovy injection is also used for adults with noncirrhotic MASH (a fatty liver disease) with moderate to advanced liver scarring, and for weight management in children 12 and older with obesity.

Read the rest of what Semaglutide is prescribed for

Ozempic is an injection used with diet and exercise to improve blood sugar control in adults with type 2 diabetes. It also lowers the risk of major cardiovascular events in adults with type 2 diabetes and established cardiovascular disease. Ozempic is not for type 1 diabetes.

Lemongrass has been studied for:

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

    Lemongrass for diabetes

    Although there has been interest in using oral lemongrass for diabetes, there is insufficient reliable information about the clinical effects of lemongrass 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 Semaglutide on your own; if you are taking Lemongrass for the same health topic, tell your prescriber, especially if the medicine is being adjusted to a target.

From our pharmacist’s overview on the Semaglutide page

“Semaglutide (Ozempic, Rybelsus, Wegovy) lowers blood sugar, and so do most of the 256 supplements on this page, which is why I read this list with real vigilance rather than a shrug. Nearly all of the entries either add to its glucose-lowering effect and raise the risk of hypoglycemia, or push sugar the other way and blunt it, as niaci…”

About Lemongrass

What is Lemongrass?

Lemongrass
  • Digestive upset
  • Anxiety and stress
  • Antimicrobial/antifungal
  • Insect repellent
  • Flavoring in food and drinks

Lemongrass is a fragrant tropical grass widely used as a cooking herb, a tea, and an aromatherapy oil. It is generally considered safe in the small amounts used in food, but most of its claimed health benefits come from laboratory or animal studies rather than strong human research. Talk with your pharmacist or doctor before using concentrated supplements or the essential oil, especially if you are pregnant or breastfeeding.

Cymbopogon citratus · Poaceae · Leaves, stalks, and essential oil · Tea, fresh or dried herb, capsules, essential oil, topical preparations

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

Lemongrass: dosing

There is no official standardized dose for lemongrass. The amount used depends on the form, such as tea, capsule, or essential oil.For tea, people commonly steep a small amount of dried or fresh leaves in hot water. For supplements, follow the directions on the product label, since strength varies from brand to brand.

Taking Lemongrass and Semaglutide Together: Common Questions

Is it safe to take Lemongrass with Semaglutide?
We do not list a known interaction between Lemongrass and Semaglutide. 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.
Are Lemongrass and Semaglutide 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 Lemongrass in each. That is a conversation for your prescriber, especially if Semaglutide is being adjusted to a target.
How was the Lemongrass and Semaglutide combination checked?
Interactions in our licensed database are recorded against drug classes. Semaglutide is filed under 2 classifications, and Lemongrass has documented interactions with 3 drug classes — none of Semaglutide'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 Lemongrass interact with any other medications?
Yes. Lemongrass has 710 documented drug interactions in our database — Semaglutide 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 Semaglutide interact with any supplements?
Yes. Semaglutide has documented interactions with 256 supplements in our database — Lemongrass is not one of them. The Semaglutide interaction page linked on this page lists every one, ranked by severity.
