The bottom line No known interaction

We found no known interaction between Lemongrass and Diclofenac 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.

Lemongrass and Diclofenac

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 Diclofenac 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 safety at a glance

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 Diclofenac

Interactions in our licensed database are recorded against drug classes, not just single drug names. Diclofenac is filed under 10 classifications — including nonsteroidal anti-inflammatory drugs (nsaids), cytochrome p450 2c9 (cyp2c9) substrates, anticoagulant/antiplatelet 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 Diclofenac’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 Diclofenac’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 Diclofenac’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. 10 of them are worth acting on rather than waiting out — marked below.

  • Loss of vision Worth acting on
  • Hearing loss Worth acting on
  • Bleeding in the gut Worth acting on
  • High potassium Worth acting on
  • Unsteadiness Worth acting on
  • Low blood sugar Worth acting on
  • A heart attack Worth acting on
  • Pancreatitis Worth acting on
  • Yellowing of the skin or eyes Worth acting on
  • Heart failure Worth acting on

From the ADVERSE REACTIONS section of the FDA label for Diclofenac. Read the label on DailyMed › Where a percentage is shown, it is the share of 164,880 voluntary FDA FAERS reports for Diclofenac that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. 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.

See Every Supplement That Interacts With Diclofenac

This page covers Lemongrass only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Diclofenac page lists 306 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), Asarabacca (major), Beer (major), Danshen (major) and Piracetam (major).

By severity: 7 major · 265 moderate · 34 minor.

From our pharmacist’s overview on the Diclofenac page

“Diclofenac (Zorvolex) is an NSAID pain reliever that already stresses the stomach lining and kidneys on its own, so treat this list as a real safety issue, not fine print. Two thirds of the 306 supplements on file can thin the blood or slow clotting, and stacked on an NSAID that raises the odds of stomach bleeding.”

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.

About Diclofenac

What Is Diclofenac Used For?

Brand name: Zorvolex

Diclofenac sodium topical gel is used to treat actinic keratoses (AK) — rough, scaly skin patches that form after years of sun exposure. These patches are considered precancerous, meaning they can develop into skin cancer if left untreated.

This is a topical gel, meaning it is applied directly to the skin over the affected area rather than taken by mouth. It belongs to the NSAID (nonsteroidal anti-inflammatory drug) family.

Most-Reported Side Effects for Diclofenac

From FAERS, the FDA’s public side-effect reporting system (164,880 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.

Fatigue 14,336 reports
Arthralgia 11,682 reports
Rash 11,262 reports
Rheumatoid arthritis 11,000 reports
Nausea 10,099 reports
