HelloPharmacist Scorecard of Lemongrass by Hawaii Pharm

Our pharmacy team’s full take, with four database checks built into the cards below — a summary of what is known, not a grade of the product itself.

What’s inside

Full disclosure
Ingredient Transparency · database check
Full

Every active ingredient lists its own amount on the label.

Why this rating?
  • The label discloses an exact amount for 1 of its 1 active ingredient.
  • No proprietary blends here — you can verify the dose of every single component.

This product contains one active ingredient: lemongrass stalk extract in a dried form. It's formulated as a liquid with alcohol, water, and glycerin as inactive ingredients (the base that carries the extract).

Does it work?

Couldn't assess
Evidence for Intended Use · database check
By FDA rules, dietary supplements can’t claim to treat, cure, or prevent disease — so labels speak in careful marketing language. We discern each product’s intended use from its name, label claims, and label statements, then grade the clinical evidence for that use. How these ratings are computed
Not assessable

This is a single-ingredient Lemongrass product and its label doesn't state a use — see Lemongrass's own graded uses on its monograph.

Why this rating?
  • We looked at the product name, claims, and label statements and couldn't find a stated purpose to grade.

The data we hold on lemongrass doesn't establish reliable evidence for any of the uses it's traditionally claimed to address — headache, cold, cough, diabetes, epilepsy, and fatigue all fall short of proven benefit. That doesn't mean it doesn't work; it means the studies strong enough to confirm it haven't been done or aren't in our records yet.

The evidence, ingredient by ingredient Lemongrass

How safe is it?

Some data gaps
Safety Information · database check
Some gaps

Safety data exists for these ingredients, but with some important gaps.

Why this rating?
  • We hold adverse-effect (side-effect) data for 0 of the 1 matched ingredient.
  • Pregnancy & breastfeeding safety ratings cover 1 of 1.
  • General safety write-ups exist for 1 of 1.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Lemongrass in food amounts is generally well tolerated. However, concentrated extracts like this liquid carry less safety data, and medicinal or concentrated doses have raised concerns based on limited evidence and traditional cautions.

The safety information advises against use in medicinal amounts. For pregnancy, the data rates lemongrass as likely unsafe — if you're pregnant or planning to become pregnant, don't use this product without talking to your doctor.

Lactation safety data isn't on file for lemongrass, so discuss use with your healthcare provider if you're breastfeeding.

Side effects, ingredient by ingredient Lemongrass

Meds to double-check

Moderate interaction found
Known Interaction Concern · database check
Moderate identified

The most serious documented interaction for these ingredients is Moderate. Check your medications for a personalized result.

Why this rating?
  • 1 of the 1 matched ingredient can interact with medications — Lemongrass.
  • The most serious interaction on file is rated Moderate.
  • For scale: 709 individual medications appear in the full list. A big number alone doesn't make a product dangerous — what matters is whether YOUR medication is on it, so run yours through the interaction checker on this page.

Before starting this product, double-check the following with your doctor or pharmacist: sedatives like pentobarbital, medications processed through the CYP3A4 enzyme (a very large group including many blood pressure, cholesterol, and immunosuppressant drugs), and glucuronidated drugs. If any of your medications fit these categories, confirm it's safe to combine before you take it.

The bottom line

Scorecard at a glanceFully disclosed formula with no assessable stated purpose. Moderate medication interactions have been identified, and some safety-information gaps remain.

This is a single-ingredient herbal extract with established interactions across a broad range of medications and limited evidence of benefit. If you take any prescription medication — especially sedatives, heart drugs, or anything processed by your liver — check with your doctor or pharmacist first.

Avoid it if you're pregnant, and don't use medicinal amounts without personalized medical advice.

Likelihood Possible Evidence D
Pentobarbital (Nembutal)

Theoretically, lemongrass might increase the effects and adverse effects of pentobarbital.

Lemongrass by Hawaii Pharm: Common Questions

Does Lemongrass by Hawaii Pharm interact with any medications?
Yes. Based on its ingredients, Lemongrass has a known interaction with 708 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Lemongrass contains a single active ingredient, and that one ingredient can interact with many different medications on its own. We check it against each medication and show the mechanism responsible.
Where does this information come from?
The product label data comes from the NIH Dietary Supplement Label Database (DSLD); the interaction data is built on the Natural Medicines database and reviewed by HelloPharmacist pharmacists.
Can I take this while I'm pregnant?
No — the safety data rates lemongrass as likely unsafe in pregnancy. Don't use this product if you're pregnant or planning to become pregnant. Talk with your doctor if you're considering it.
Does lemongrass actually work for colds or headaches?
The evidence isn't established in our data. Lemongrass is often used for these purposes, but reliable studies strong enough to prove it works aren't on file — that doesn't mean it doesn't, just that we can't confirm it from what we hold.
Is this safe to use every day?
The safety notes advise caution with concentrated extracts like this one — there's limited data on long-term use, and medicinal or concentrated amounts are flagged as something to avoid. Occasional use in food is safer, but daily doses of this liquid extract should be cleared with your doctor first.
Why does this interact with so many drugs?
Lemongrass affects how your liver processes medications through two major pathways — CYP3A4 and glucuronidation — and these pathways handle hundreds of different drugs. That wide reach is why the interaction count is high, even though the individual risks are rated Moderate.
