HelloPharmacist Scorecard of Lemon Balm Extract by Oregon's Wild Harvest

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

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: fresh lemon balm extract. Lemon balm is an herb from the mint family, traditionally used for its calming properties.

The liquid form also includes alcohol as an inactive ingredient.

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 Lemon Balm's overall clinical evidence instead.

Moderate

Some clinical evidence supports Lemon Balm 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: Herpes labialis (cold sores) — rated "Possibly Effective" (Natural Medicines).
  • On file: Depression — rated "Possibly Effective" (Natural Medicines).
  • On file: Stress — rated "Possibly Effective" (Natural Medicines).

The evidence we hold shows lemon balm is possibly effective for cold sores (herpes labialis) and for relieving stress and depressed mood. The data suggests benefit, but the evidence isn't as strong as it is for some other supplements or medications.

Talk with your doctor about whether it makes sense for what you're aiming to treat.

The evidence, ingredient by ingredient Lemon Balm

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.

Lemon balm is generally well tolerated when used short-term in healthy adults, though high doses and long-term use haven't been well studied. Safety data in pregnancy is not enough to know either way—your doctor or pharmacist can help you decide if it's right for you during pregnancy.

Breastfeeding safety information is also limited; discuss it with your healthcare provider before using while nursing. In clinical trials, dizziness and sedation were reported at no higher rates than placebo.

Topical use (1% cream) on cold sores was rarely linked to skin irritation or sore exacerbation, also no more often than placebo.

Side effects, ingredient by ingredient Lemon Balm

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 — Lemon Balm.
  • The most serious interaction on file is rated Moderate.
  • For scale: 264 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 product, check with your doctor or pharmacist if you use any central nervous system depressants—sedatives, sleep aids, and some pain or anxiety medications—since lemon balm may add to their drowsy effects (Moderate). Also confirm if you're on thyroid hormone replacement therapy, because lemon balm may reduce its effectiveness (Moderate).

The bottom line

Scorecard at a glanceFully disclosed formula with some supporting evidence behind its ingredients' uses. Moderate medication interactions have been identified, and safety information is well characterized.

If you're looking to ease stress, support mood, or treat a cold sore, lemon balm is worth discussing with your doctor or pharmacist—especially if you take sedating medications or thyroid hormone. Because this product may interact with CNS depressants and thyroid drugs, check your exact medications with the tool on this page before you start.

Your healthcare provider can tell you whether it's a good fit for you.

Lemon Balm, Fresh2 drug types · 264 drugs

Cns Depressants

Theoretically, concomitant use of lemon balm might have additive effects with CNS depressant drugs.
Lemon balm seems to have CNS depressant activity in animals and in humans.

Likelihood Possible Evidence B
Thyroid Hormone

Theoretically, lemon balm might interfere with thyroid hormone replacement therapy.
In vitro, constituents of lemon balm extract bind to thyroid stimulating hormone (TSH), preventing TSH receptor-binding and leading to the inhibition of TSH-stimulated adenylate cyclase activity. In animals, lemon balm extract has been shown to decrease levels of circulating TSH and inhibit thyroid secretion.

Lemon Balm Extract by Oregon's Wild Harvest: Common Questions

Does Lemon Balm Extract by Oregon's Wild Harvest interact with any medications?
Yes. Based on its ingredients, Lemon Balm Extract has a known interaction with 264 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Lemon Balm Extract 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.
Will lemon balm make me drowsy?
Lemon balm does have calming properties and can theoretically add to the effect of sedating drugs. In clinical trials, though, dizziness and sedation weren't reported any more often than with placebo. If you're sensitive to sedation or take sleeping pills, mention this product to your pharmacist first.
Can I use this if I take thyroid medication?
Lemon balm may interfere with how well thyroid hormone replacement works by binding to receptors your body needs to respond to the hormone. Check with your doctor before starting; they may want to monitor your thyroid levels or adjust your dose if you use both.
Is lemon balm extract safe to use long-term?
It's generally well tolerated for short-term use, but long-term safety and effects of high doses haven't been well studied. If you're thinking about using it regularly, talk it over with your healthcare provider.
What is lemon balm used for?
The evidence we hold shows lemon balm is possibly effective for cold sores, stress relief, and supporting mood. It's an herb from the mint family with a history of traditional use for calming.
Can I take this while pregnant or breastfeeding?
There isn't enough reliable safety data to say either way. During pregnancy, it's best avoided unless your doctor advises otherwise. If you're breastfeeding, talk to your doctor before using, since safety information is limited.
Does alcohol in the liquid formulation add any risk?
This product contains alcohol as an inactive ingredient. Research shows lemon balm used with alcohol does not affect reaction time or cognitive performance in the studies we hold, but if you're avoiding alcohol for any reason, mention the ingredient list to your pharmacist.
