HelloPharmacist Scorecard of Eucalyptus and Spearmint 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
Low disclosure
This liquid contains two active herbal extracts: certified organic eucalyptus and certified organic spearmint, blended in a proprietary formula. The product also includes menstruum as an inactive ingredient — a solvent used to extract and preserve the herbal compounds.
Eucalyptus extract is included for its traditional use, though the data we hold shows insufficient evidence to rate its effectiveness for any condition. Spearmint extract similarly lacks established evidence for conditions like cognitive function, flatulence, or irritable bowel syndrome in the data available to us.
Does it work?
Couldn't assess
The evidence we hold doesn't establish that either ingredient in this blend is effective for any condition. Eucalyptus has been studied for acne, bronchitis, asthma, burns, and cancer, but the data rates all of these as having insufficient reliable evidence.
Spearmint similarly shows insufficient evidence for age-related cognitive decline, cognitive function, flatulence, IBS, postoperative nausea, and osteoarthritis. If you're considering this product for a specific health goal, talk it over with your doctor or pharmacist to see if there's stronger evidence for a different approach.
How safe is it?
Well-documented data
Eucalyptus carries real toxicity risks, especially if taken by mouth. The undiluted oil is poisonous even in small amounts — as little as 1 mL can cause central nervous system depression, shallow breathing, seizures, coma, or death.
Even diluted oral eucalyptus can cause nausea, vomiting, and diarrhea. Topically, it may cause burning, itching, or redness.
Rarely, inhaling eucalyptus or consuming it has triggered seizures and asthma flare-ups in sensitive people. Spearmint is well tolerated when eaten as food or tea, but concentrated supplements warrant caution.
Topically, spearmint oil and leaves have caused allergic skin reactions and mouth sores in sensitive individuals. One clinical trial reported anxiety in a person taking 600 mg daily, though causation isn't certain.
Pregnancy data rates spearmint as likely safe, though one entry notes possibly unsafe — the facts are mixed, so confirm with your doctor. Lactation is rated likely safe.
For eucalyptus, pregnancy and lactation are rated likely safe, but safety data is limited and the toxicity risk means you should avoid oral use and keep the product away from children and pregnant persons.
Meds to double-check
Moderate interaction found
Before taking this product, double-check with your pharmacist or doctor if you take diabetes medications (risk of low blood sugar), sedatives or CNS depressants (spearmint may alter their effect), amphetamines (eucalyptus may reduce effectiveness), pentobarbital or other barbiturates (eucalyptus may lower effectiveness), or any drug that stresses the liver (spearmint may increase damage risk). Also confirm if you take any medication broken down by your liver's CYP450 system (CYP1A2, CYP2C19, CYP2C9, or CYP3A4), since eucalyptus may raise their blood levels.
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.
This product is best reserved for occasional inhalation or aromatherapy rather than internal use, given eucalyptus's toxicity risk and the unproven effectiveness of both herbs. If you take any medication — especially diabetes drugs, sedatives, or medications processed by your liver — talk with your doctor or pharmacist before using it.
Pregnant or breastfeeding? Check with your healthcare provider first, since the safety data is limited.

Eucalyptus and Spearmint by Herbal Terra Drug Interactions
HelloPharmacist Interaction Report
Herbal Terra's Eucalyptus and Spearmint is a two-ingredient liquid blend that carries documented interactions with medications.
The main concern comes through eucalyptus, which may affect how your body processes several classes of drugs, and through spearmint, which can interact with sedatives and drugs that stress the liver.
Read the full breakdown — every affected drug type, severity by severity
Eucalyptus may theoretically increase blood levels of medications broken down by your liver's CYP450 enzymes — specifically CYP1A2, CYP2C19, CYP2C9, and CYP3A4 substrates. These interactions are rated Moderate severity based on lab research, though they haven't been confirmed in humans yet.
Additionally, eucalyptus may raise your risk of low blood sugar (hypoglycemia) if you take diabetes medications, and animal research suggests it might reduce the effectiveness of amphetamines or pentobarbital (a barbiturate sedative).
Spearmint introduces two more Moderate-severity concerns. It may alter how sedating medications (CNS depressants) work — the effect is unclear because lab studies suggest it could sedate you, but human gum-chewing studies showed the opposite.
High-dose spearmint may also increase liver damage risk if you're already on drugs that stress the liver (hepatotoxic drugs).
Altogether, these interactions span 1,158 individual medications. Before you start this product, run your exact medications through the search tool on this page or check with your doctor or pharmacist.

Cytochrome P450 3A4 (Cyp3A4) Substrates
Theoretically, eucalyptus might increase the levels of CYP3A4 substrates.
In vitro research suggests that eucalyptus oil might inhibit CYP3A4, although this has not been reported in humans.
Pentobarbital (Nembutal)
Theoretically, inhaling eucalyptol might reduce the effectiveness of pentobarbital.
Animal research suggests that inhaling eucalyptol reduces the level of pentobarbital that reaches the brain.
certified organic Spearmint extract
Cns Depressants
Theoretically, spearmint might alter the sedative effects of CNS depressants.
Animal research suggests that (-)-carvone, a major constituent of spearmint, has sedative effects. However, in humans, chewing spearmint-flavored gum induced arousal effects.
Hepatotoxic Drugs
Theoretically, high doses of spearmint might increase the risk of liver damage when taken with hepatotoxic drugs.
Animal research suggests that drinking spearmint tea for 30 days can increase markers of liver damage, including aspartate aminotransferase (AST) and alanine aminotransferase (ALT), and cause liver degeneration and necrosis, in a dose-dependent manner. This effect has not been reported in humans.
