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.

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. The extract also includes menstruum, an inactive ingredient used as a solvent in the extraction process.

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 we hold doesn't establish that lemongrass works reliably for any of the conditions it's marketed for — headache, common cold, cough, diabetes, epilepsy, and fatigue all carry a rating of insufficient reliable evidence to rate. That doesn't mean it doesn't work; it means the scientific data on file doesn't support a confident claim one way or the other.

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, but this is a concentrated extract, and concentrated extracts have much less safety data than food use. The safety notes advise against medicinal or concentrated amounts due to limited information and traditional safety concerns.

Pregnancy safety data rates lemongrass as likely unsafe — the safety information on file advises against use during pregnancy. No data is on file for lactation; talk with your doctor or pharmacist if you're breastfeeding and considering 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 with your pharmacist or doctor if you take pentobarbital (Nembutal) or other sedatives, drugs that are CYP3A4 substrates (a large group including many heart and blood pressure medications, certain statins, and others), or drugs that go through glucuronidation. Because this is a concentrated extract with interaction potential across a wide range of medications, a personal medication review is important.

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.

If you take any prescription medications, especially sedatives, heart drugs, or anything your liver processes, you'll want to check your exact list before starting this concentrated extract. The evidence for what it actually does is too thin to support any strong claim.

Talk it over with your doctor or pharmacist — they know your health and medications and can tell you whether it's right for you.

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.
What's lemongrass actually supposed to do?
This extract is marketed for headache, cold, cough, diabetes, epilepsy, and fatigue — but the evidence we hold isn't strong enough to say it reliably does any of those things. You'd want to talk with your doctor about whether it makes sense for whatever you're trying to address.
Is this just the lemongrass you use in cooking?
No. Cooking lemongrass is likely safe, but this is a concentrated liquid extract. Concentrated forms have much less safety data, and the safety cautions advise against medicinal amounts because there's limited information about how safe they really are.
Can I take this if I'm pregnant?
The safety data rates lemongrass as likely unsafe in pregnancy. If you're pregnant or planning to be, skip it and talk with your doctor about what's safe for you.
What's menstruum in the ingredient list?
Menstruum is the solvent used to extract the lemongrass — it's an inactive ingredient that helps pull the plant material into liquid form. It's not an active part of what the supplement does.
How many medications does lemongrass actually interact with?
It potentially affects 709 individual medications across three main categories: drugs your liver processes through CYP3A4, drugs your body clears through glucuronidation, and pentobarbital specifically. That's why checking your exact medications is so important before you start.
