HelloPharmacist Scorecard of Lemongrass by Zongle Therapeutics

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. The liquid form includes steam-distilled lemongrass oil as an inactive ingredient (the vehicle that carries the active lemongrass).

Does it work?

Not established
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 established

The graded evidence we hold for these ingredients covers different conditions than the ones this product is marketed for, so there's no established rating for its stated use — see Lemongrass's own graded uses on its monograph.

Why this rating?
  • The label markets this product for: supports healthy digestion and skin health.
  • We looked for evidence on: Nausea and vomiting, Abdominal pain, indigestion, gastrointestinal comfort.
  • The closest evidence on file: Lemongrass is rated "Insufficient Reliable Evidence To Rate" for Nausea and vomiting (Natural Medicines).
  • Also on file: Lemongrass is rated "Insufficient Reliable Evidence To Rate" for Abdominal pain.

The evidence we hold does not establish that lemongrass is effective for any of the conditions it's marketed toward—headache, common cold, cough, diabetes, epilepsy, or fatigue. All six uses are listed as having insufficient reliable evidence to rate.

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, but this product is a concentrated liquid extract, and concentrated forms have less safety data behind them. Medicinal or concentrated amounts should be avoided due to limited safety information and traditional safety concerns.

Lemongrass is rated likely unsafe in pregnancy—the safety data advises against use during pregnancy. We hold no data on safety during breastfeeding, so talk with your doctor or pharmacist for personalized advice if you're nursing.

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 you start, double-check your medications against these three drug types with your pharmacist: pentobarbital and other sedatives (risk of increased drowsiness and side effects), CYP3A4 substrates like certain cholesterol and blood pressure medications (risk of higher levels and side effects), and glucuronidated drugs (risk of lower effectiveness). The interaction data we hold covers a very broad range of medications, so even if your drug isn't in one of these categories, it's worth confirming.

The bottom line

Scorecard at a glanceFully disclosed formula with no established evidence rating for its marketed use. Moderate medication interactions have been identified, and some safety-information gaps remain.

Because we don't have reliable evidence that lemongrass works for its marketed uses, and because it interacts with a very large number of medications through multiple pathways, this isn't a straightforward choice. If you're considering it, check your medications first using the tool on this page, and talk it over with your doctor or pharmacist—especially if you take any sedatives, heart drugs, blood pressure medications, or other prescription drugs.

Likelihood Possible Evidence D
Glucuronidated Drugs

Theoretically, lemongrass might increase the clearance and decrease the levels of glucuronidated drugs.
Animal research shows that lemongrass and its constituent citral induce uridine diphosphoglucuronosyl transferase (UGT), the major phase 2 enzyme that is responsible for glucuronidation.

Likelihood Possible Evidence D
Pentobarbital (Nembutal)

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

Lemongrass by Zongle Therapeutics: Common Questions

Does Lemongrass by Zongle Therapeutics 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.
Is lemongrass safe to take while pregnant?
No. Lemongrass is rated likely unsafe in pregnancy, so the safety data advises against use if you're pregnant or planning to become pregnant. Talk with your doctor before taking any supplement during pregnancy.
Does this lemongrass liquid actually work for colds or headaches?
We don't have reliable evidence backing lemongrass for either of those uses. The data rates both as having insufficient reliable evidence—meaning the science isn't there yet to say whether it helps.
Why does the label say to avoid medicinal amounts?
Concentrated forms like this liquid extract have less safety data than lemongrass in everyday food amounts. Medicinal doses come with traditional safety concerns and not enough modern research to be sure they're safe, so the advice is to stick to occasional food use rather than therapeutic amounts.
What's the difference between this liquid and lemongrass tea?
This is a concentrated extract, which is much more potent than brewed tea. Food amounts of lemongrass are likely safe, but concentrated forms have weaker safety data and carry the interaction risks we've covered.
