HelloPharmacist Scorecard of Lemongrass by Herbal Terra

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.

From our pharmacy team — supplement deep dive

Generated from HelloPharmacist’s pharmacist-curated databases and editorial rules · Last generated Aug 20, 2026

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: certified organic Lemongrass (Cymbopogon citratus) as a dried stalk liquid extract. Lemongrass is a tropical grass used in traditional medicine and cooking.

The inactive ingredient listed is menstruum, a liquid base used to concentrate and preserve 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 evidence on lemongrass for headache, common cold, cough, diabetes, epilepsy, and fatigue is insufficient — we don't have reliable data to say whether it works for any of these uses. You'd be taking it without established proof of benefit.

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 likely safe. However, the safety data for concentrated extracts like this one is limited.

The safety notes advise against medicinal or concentrated amounts due to that gap in data and traditional safety concerns. There are no adverse effects recorded in our data.

During pregnancy, lemongrass is rated likely unsafe — the safety data advises against it. For lactation, we have no safety data on file.

If you're pregnant, nursing, or thinking about it, talk with your doctor or pharmacist before taking this product.

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 taking this product, check whether you take any CYP3A4 substrates (medications your liver breaks down through this pathway — statins, certain blood pressure drugs, immunosuppressants, and many others fall here), glucuronidated drugs, or pentobarbital. All three categories carry Moderate interaction risk.

Use the medication search tool on this page to look up your exact prescriptions, and confirm with your own doctor or pharmacist.

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 extract with significant interaction potential — particularly with a very large group of medications your liver metabolizes. If you take any prescription drugs, check them against the tool on this page and discuss the result with your doctor or pharmacist before starting.

Pregnant or nursing people should avoid it. The evidence for its intended uses isn't established, so you'd be taking it without clear proof it works.

Lemongrass by Herbal Terra: Common Questions

Does Lemongrass by Herbal Terra 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 lemongrass if I'm pregnant or breastfeeding?
During pregnancy, lemongrass is rated likely unsafe — the safety data advises against it. For breastfeeding, we have no safety data on file. Talk with your doctor or pharmacist about whether it's right for you.
Does lemongrass actually work for headaches, colds, or other conditions?
The evidence on lemongrass for headache, common cold, cough, diabetes, epilepsy, and fatigue is insufficient — we don't have reliable data showing it works for any of these. You'd be trying it without established proof of benefit.
Is this extract safe to use every day?
Lemongrass in food amounts is likely safe, but this is a concentrated medicinal extract. The safety data for concentrated amounts is limited, and the traditional caution is to avoid medicinal doses. Occasional food use is one thing; daily medicinal use is another. Ask your pharmacist whether daily use fits your situation.
What is the 'menstruum' in the ingredients list?
Menstruum is an inactive liquid base — like a solvent — used to concentrate and preserve the lemongrass extract. It's not the active ingredient.
Why does this product interact with so many medications?
Lemongrass affects how your liver processes drugs through two major pathways: CYP3A4 and glucuronidation. These pathways clear hundreds of different medications, which is why the interaction list is long. Your individual medications may or may not be affected — that's why you need to check your specific list.
