HelloPharmacist Scorecard of Eucalyptus by Herb Xtra

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 Jul 30, 2026

What’s inside

Low disclosure
Ingredient Transparency · database check
Low

Most active ingredients don't disclose an individual amount — you can't tell how much of each you're getting.

Why this rating?
  • The label discloses an exact amount for 0 of its 3 active ingredients.

Herb Xtra Eucalyptus is a capsule with 3 ingredients: gelatin (the capsule shell itself), water, and eucalyptus leaf extract. Eucalyptus is the active ingredient here — the others are there to deliver it to you.

The product doesn't list any inactive fillers beyond what's needed to make the capsule.

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

The label doesn't state a purpose we can grade — see each ingredient's own graded uses on its monograph instead.

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 eucalyptus for health purposes isn't established in our data. We hold effectiveness ratings for acne, bronchitis, asthma, burns, and cancer, but all are rated insufficient reliable evidence to rate — meaning the research so far hasn't been strong enough to confirm whether it works for these uses or not.

The evidence, ingredient by ingredient Gelatin Eucalyptus

How safe is it?

Well-documented data
Safety Information · database check
Well characterized

Adverse-effect, pregnancy, and general safety data are on file for most of these ingredients.

Why this rating?
  • We hold adverse-effect (side-effect) data for 2 of the 2 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 2 of 2.
  • General safety write-ups exist for 2 of 2.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Orally, diluted eucalyptus oil is generally well tolerated, but the facts caution that undiluted eucalyptus oil can be poisonous if swallowed and cause serious toxicity at doses as low as 1 mL. Common side effects from oral use include diarrhea, nausea, and vomiting; topically you might see burning, itching, redness, or stinging.

Rare but serious concerns include seizures and central nervous system depression, particularly with undiluted oil. Gelatin is widely consumed as a food and generally well tolerated orally — belching, bloating, and indigestion are the most common side effects — though rare allergic reactions including anaphylaxis have been reported.

For pregnancy and lactation, eucalyptus is rated likely safe overall, and gelatin is rated likely safe in pregnancy and likely safe while breastfeeding.

Side effects, ingredient by ingredient Gelatin Eucalyptus

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 2 matched ingredients can interact with medications — Eucalyptus.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: diabetes medications.
  • For scale: 879 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 your medications before starting, especially if you take blood-sugar drugs, any drug metabolized by your liver's CYP1A2, CYP2C19, CYP2C9, or CYP3A4 systems, amphetamines, or pentobarbital. These are Moderate-severity concerns based on lab research that hasn't yet been confirmed in people.

Talk with your doctor or pharmacist about whether this product is right for you.

The bottom line

Scorecard at a glanceFormula with limited ingredient disclosure with no assessable stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

If you're curious about eucalyptus for respiratory or skin concerns, know that the evidence isn't strong enough yet to confirm it works. The bigger issue is that it may interact with a large number of medications processed by your liver, and you'll want to talk with your doctor or pharmacist about your specific prescriptions before you start.

Also be careful with the dose — undiluted eucalyptus oil is toxic and should never be taken by mouth.

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 eucalyptus safe to take by mouth?
Diluted eucalyptus oil is generally well tolerated, but undiluted oil can be poisonous at very small doses — as little as 1 mL — and cause serious toxicity including seizures, coma, and death.

Can I take this while pregnant or breastfeeding?
Eucalyptus in this product is rated likely safe in pregnancy and lactation based on the data we hold. Gelatin, the capsule, is also rated likely safe while breastfeeding.
