HelloPharmacist Scorecard of Clove by L.A. Naturals

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 16, 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 1 active ingredient.

This product contains one active ingredient: certified organic clove extract in liquid form. Clove is the flower bud of the clove plant, and its main active compound is eugenol, which gives clove its characteristic warming flavor and medicinal properties.

The liquid also holds two inactive ingredients — grain alcohol and deionized water — that serve as the base to keep the clove extract in solution.

Does it work?

Moderate evidence
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

This product doesn't appear to be marketed for a specific use, so we graded Clove's overall clinical evidence instead.

Moderate

Some clinical evidence supports Clove for:

Why this rating?
  • We looked at the product name, claims, and label statements and couldn't find a stated purpose to grade.
  • Since the label doesn't commit to one use, we graded the ingredient's overall clinical evidence instead.
  • On file: Ventilator-associated pneumonia (VAP) — rated "Possibly Effective" (Natural Medicines).

The evidence we have on clove is limited. It's possibly effective for ventilator-associated pneumonia (VAP), a serious lung infection in hospitalized patients on breathing machines, though this use is specialized and not something most people would consider at home.

For cough, acute pain, and digestive upset (dyspepsia), there isn't enough reliable evidence to say whether clove works. If you're thinking about clove for one of those everyday purposes, the science doesn't yet back it up.

The evidence, ingredient by ingredient Clove

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.

Clove is well tolerated as a food spice. The catch is dose — concentrated clove oil and supplements are a different story.

As little as 5 to 10 mL of clove oil can be toxic in children, and serious side effects like liver failure have been reported (though rarely) with oral doses. When applied to skin, clove is generally well tolerated, though it can cause burning, itching, irritation, or contact dermatitis in sensitive people.

Inhaling clove — whether from clove cigarettes or as a vapor — carries risks like high blood pressure, rapid heartbeat, and rarely, severe lung problems. The product's safety in medicinal doses beyond food amounts hasn't been fully studied, so stick to food-spice amounts unless your doctor clears a higher dose.

Side effects, ingredient by ingredient Clove

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 — Clove.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; diabetes medications.
  • For scale: 978 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 take clove, double-check with your pharmacist or doctor if you're on diabetes medications (insulin or oral diabetes drugs), blood thinners (anticoagulants or antiplatelet agents), or any drug metabolized by the liver enzymes CYP2D6, CYP1A2, CYP3A4, or CYP2C9 — a category that includes hundreds of common medications. If you use topical ibuprofen, avoid applying clove oil to the same area.

The bottom line

Scorecard at a glanceFormula with limited ingredient disclosure with some supporting evidence behind its ingredients' uses. Moderate medication interactions have been identified, and safety information is well characterized.

Clove by L.A. Naturals is a single-ingredient extract that interacts with a wide range of medications, most notably diabetes drugs and those processed by major liver enzymes.

It's well tolerated in small food-spice amounts, but concentrated doses can be toxic — especially in children. If you take any prescription medications or have diabetes, check with your doctor or pharmacist before adding this to your routine.

Antidiabetes Drugs

Theoretically, concomitant use of clove extracts with antidiabetes drugs might increase the risk of hypoglycemia.

Clove by L.A. Naturals: Common Questions

Does Clove by L.A. Naturals interact with any medications?
Yes. Based on its ingredients, Clove has a known interaction with 977 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Clove 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 clove safe to use while pregnant or breastfeeding?
The data we have rates clove as likely safe in pregnancy and lactation. That said, the safety evidence is limited to food-spice amounts, not medicinal or supplement doses. If you're pregnant or nursing and want to use clove beyond cooking, talk it over with your doctor or midwife to make sure the dose and form are right for you.
What are the side effects of clove?
As a spice, clove is well tolerated. When used as a concentrated oil or supplement at high doses, it can cause burning or irritation on the skin, mouth sores, or if swallowed in large amounts, serious effects like liver damage or confusion. In children, even small amounts of clove oil (5–10 mL) can be toxic. If you take more than a food-spice amount and notice mouth or throat burning, stomach pain, or any unusual symptoms, stop and call your doctor.
Can clove help with pain or cough?
The evidence isn't there yet. We have insufficient reliable data on clove for acute pain, cough, or digestive upset. It may help — people have used clove that way for centuries — but clinical research hasn't confirmed it yet.
What is eugenol, and why does it matter?
Eugenol is the main active compound in clove that gives it its warming, spicy flavor. It's important because lab research shows eugenol can slow how your liver processes certain medications. That's why clove may interact with hundreds of different drugs. The interaction hasn't been proven in real people yet, but it's a real possibility worth checking with your pharmacist.
Is this safe for children?
As a food spice, yes. But clove oil and supplements are not safe for children — as little as 5 to 10 mL of clove oil can be toxic in young children and cause serious effects. Keep this product out of reach of kids, and never give it to them without explicit approval from their pediatrician.
Can I use clove oil on my skin?
Topical clove is generally well tolerated, but it can cause burning, itching, irritation, or a rash (contact dermatitis) in some people. Don't apply it to broken skin, and if you experience persistent irritation, wash it off and check with your doctor. Never mix it with topical ibuprofen, as clove can increase how much ibuprofen your skin absorbs.
