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: lemongrass stalk extract in a concentrated liquid form. The extract is suspended in alcohol, water, and glycerin.

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 for lemongrass isn't established in the data we hold. It's been studied for headache, common cold, cough, diabetes, epilepsy, and fatigue, but the reliability of those studies isn't there yet — we can't rate whether it works for any of these uses.

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 is likely safe in food amounts — like when you use it to flavor tea or cooking. But this is a concentrated liquid extract, and concentrated forms have much less safety data behind them.

The safety notes advise against medicinal or concentrated amounts due to limited information and traditional concerns. No adverse effects from trials are on file.

There's no pregnancy or breastfeeding safety data available for this ingredient, so talk with your doctor or pharmacist before using it if you're pregnant, nursing, or planning either.

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.

Check any drugs your liver breaks down using the CYP3A4 enzyme, and any that are cleared through glucuronidation. Also check if you're taking pentobarbital (Nembutal).

Because lemongrass affects major enzyme systems, the interaction tool on this page is essential before you start.

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.

Lemongrass extract interacts with a broad range of medications through multiple liver pathways. If you take any prescription drugs — especially those metabolized by your liver — you need to check them against this product before starting.

Talk to your pharmacist about your full medication list.

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.
Does this lemongrass extract actually work for anything?
The evidence isn't established yet. It's been studied for headache, common cold, cough, diabetes, epilepsy, and fatigue, but we don't have enough reliable data to say whether it works for any of these.
Is it safe to use this concentrated liquid every day?
Not enough is known about safety with daily concentrated use. Lemongrass is safe in food amounts, but this is a concentrated extract, and concentrated forms haven't been studied enough. Stick to occasional use and talk with your pharmacist if you're considering daily doses.
Can I use this while I'm pregnant?
There isn't enough data to know either way. Talk with your doctor or pharmacist before using it if you're pregnant or breastfeeding — they can weigh your situation and advise you.
What's the difference between using lemongrass as food and this liquid extract?
Food amounts of lemongrass are likely safe. This concentrated liquid extract hasn't been studied as thoroughly, and the safety concerns are greater with medicinal or concentrated amounts. Your pharmacist can help you understand if this product fits your needs.
Why does this interact with so many medications?
Lemongrass affects two major liver enzyme systems — CYP3A4 and glucuronidation — that your body uses to break down hundreds of different drugs. That's why the interaction count is so high; it's not that each ingredient interacts with many drugs, but that it changes how your liver handles broad drug categories.
