HelloPharmacist Scorecard of Spearmint 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.

From our pharmacy team — supplement deep dive

Generated from HelloPharmacist’s pharmacist-curated databases and editorial rules · Last generated Sep 10, 2026

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: spearmint, a common culinary herb. The liquid also includes steam-distilled spearmint oil as an inactive ingredient (a carrier or flavoring component).

Spearmint has been used traditionally for digestive comfort and flavor, though the evidence supporting those uses in supplement form is not yet established in our data.

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 Spearmint's own graded uses on its monograph.

Why this rating?
  • The label markets this product for: healthy digestion, fresh breath, focus and mood.
  • We looked for evidence on: Flatulence, Irritable bowel syndrome (IBS), indigestion, stomach upset.
  • The closest evidence on file: Spearmint is rated "Insufficient Reliable Evidence To Rate" for Flatulence (Natural Medicines).
  • Also on file: Spearmint is rated "Insufficient Reliable Evidence To Rate" for Irritable bowel syndrome (IBS).

The evidence we hold on spearmint doesn't yet establish reliable benefit for any of its proposed uses — including age-related cognitive decline, everyday cognitive function, flatulence, irritable bowel syndrome, nausea after surgery, or osteoarthritis. That doesn't mean it doesn't work; it means the clinical trials to prove it are insufficient so far.

If you're considering spearmint for one of these reasons, talk it over with your doctor or pharmacist about what the current science shows.

The evidence, ingredient by ingredient Spearmint

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 1 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.

Spearmint is generally well tolerated when taken by mouth, especially at the amounts you'd get from food or tea. However, the safety data we hold are limited for concentrated supplements and oils at higher doses — the cautions in this data recommend sticking to food or tea amounts unless your doctor has approved a larger dose.

Allergic reactions are possible, especially with topical use (spearmint oil on skin or lips can cause rash or swelling). One person in a clinical trial reported anxiety after taking 600 mg of spearmint extract daily, though it's unclear if spearmint was the cause.

Pregnancy ratings in our data show conflicting information (Likely Safe and Possibly Unsafe both listed); talk with your doctor or pharmacist for personalized guidance if you're pregnant or nursing.

Side effects, ingredient by ingredient Spearmint

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 — Spearmint.
  • The most serious interaction on file is rated Moderate.
  • For scale: 580 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 spearmint product, check with your doctor or pharmacist if you take any drugs that damage the liver (hepatotoxic medications) or central nervous system depressants — including sedatives, sleep aids, anxiety medications, and pain relievers that cause drowsiness. These carry Moderate-severity interaction risks with spearmint.

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 safety information is well characterized.

Spearmint at food or tea amounts is generally tolerated and poses a documented Moderate risk if you take liver-damaging drugs or CNS depressants. The evidence for its effectiveness at any of its promoted uses isn't yet established in our data.

If you're pregnant, nursing, have liver disease, or take sedatives or medications that stress the liver, discuss this with your doctor or pharmacist before starting spearmint.

Spearmint2 drug types · 579 drugs

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.

Likelihood Possible Evidence D
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.

Spearmint by Zongle Therapeutics: Common Questions

Does Spearmint by Zongle Therapeutics interact with any medications?
Yes. Based on its ingredients, Spearmint has a known interaction with 579 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Spearmint 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 spearmint safe to take if I'm pregnant or breastfeeding?
Our data show conflicting ratings for pregnancy — one says Likely Safe and another says Possibly Unsafe — so there isn't clear consensus on safety. Lactation is rated Likely Safe. Because pregnancy data are mixed, talk with your doctor or pharmacist before taking this product if you're pregnant or planning to become pregnant.
Can spearmint cause allergic reactions?
Yes. Allergic contact rash or swelling of the lips can occur, especially if spearmint oil touches your skin or mouth. One person reported swelling of the soft palate after taking spearmint by mouth. If you've had allergies to spearmint or related herbs before, be cautious.
What does the evidence say spearmint actually does?
We don't yet have reliable evidence for the uses it's promoted for — age-related cognitive decline, brain function, gas, IBS, post-surgery nausea, or osteoarthritis. The evidence at this point is insufficient to rate it as effective for any of those, so if you're considering it for a specific reason, talk with your doctor about what the research currently shows.
Is this product just spearmint, or does it have other stuff in it?
The active ingredient is spearmint. The liquid also contains steam-distilled spearmint oil as an inactive ingredient (which helps carry the active component and adds flavor).
I take a sedative — is spearmint okay to combine with it?
Not without checking first. Spearmint has a Moderate-severity interaction with sedatives and other CNS depressants — animal research suggests it may have sedative effects of its own, though human data are unclear. Before starting spearmint, ask your doctor or pharmacist if it's safe alongside your specific medication.
