HelloPharmacist Scorecard of Lemon Balm Alcohol-Free by Herb Pharm

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 11, 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: lemon balm aerial parts extract, which is the above-ground portions of the lemon balm plant prepared as a liquid extract. The inactive ingredients are glycerin and distilled water.

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
Moderate

Some clinical evidence supports this product's ingredients for its stated purpose, but it isn't conclusive.

Why this rating?
  • The label markets this product for: nervous system calming.
  • We looked for evidence on: Anxiety, Stress, Insomnia, Restlessness, Nervousness.
  • The strongest evidence on file: Lemon Balm is rated "Possibly Effective" for Stress (Natural Medicines).
  • Also on file: Lemon Balm is rated "Insufficient Reliable Evidence To Rate" for Anxiety, Insomnia.

Lemon balm is possibly effective for herpes labialis (cold sores) and for stress and depression, according to the evidence we have on file. That means there's some clinical support, but the data isn't definitive enough to call it proven.

If you're considering it for one of those uses, talk with your pharmacist about what the research actually shows and whether it fits your situation.

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 for short-term use in healthy adults. The most commonly reported side effects are dizziness and sedation, though studies show these don't happen more often with lemon balm than with placebo.

High-dose and long-term safety haven't been well studied. During pregnancy, there isn't enough reliable safety data, so it's best avoided unless your doctor advises otherwise.

While breastfeeding, safety information is limited — talk to your doctor before using. One case report describes a serious heart rhythm change (atrioventricular block and QT prolongation) in a woman using a multi-ingredient product that contained lemon balm, though the extract itself may not have been responsible, and symptoms resolved when the product was stopped.

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 you start, double-check whether you take any CNS depressants (sleeping pills, anti-anxiety medications, some pain relievers) or thyroid hormone replacement — both are rated Moderate-severity interactions with lemon balm.

The bottom line

Scorecard at a glanceFully disclosed formula with some supporting evidence for its stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

Lemon balm may help with cold sores or stress, but it can slow down your brain and may interfere with thyroid medication. If you take a sedative drug or thyroid hormone, check with your pharmacist first.

Pregnant women should avoid it unless their doctor says it's okay.

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 Alcohol-Free by Herb Pharm: Common Questions

Does Lemon Balm Alcohol-Free by Herb Pharm interact with any medications?
Yes. Based on its ingredients, Lemon Balm Alcohol-Free 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 Alcohol-Free 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 this make me drowsy?
Dizziness and sedation have been reported with lemon balm, though clinical trials show it doesn't happen more often than placebo. If you're sensitive to sedating supplements or take other drugs that make you sleepy, mention it to your pharmacist.
Can I take this if I'm on thyroid medication?
Lemon balm may theoretically interfere with how thyroid hormone works in your body. Check with your doctor or pharmacist before adding this product to your routine if you take thyroid replacement therapy.
Is it safe to use long-term?
Lemon balm is well tolerated for short-term use, but long-term safety hasn't been well studied. If you're thinking of taking it regularly for weeks or months, talk to your pharmacist about what we know and don't know.
Can I use this while pregnant?
No — there isn't enough reliable safety data, so it's best avoided during pregnancy unless your doctor advises otherwise.
Is it safe while breastfeeding?
Safety information is limited. Use caution and talk to your doctor before using while breastfeeding so you can weigh the risks and benefits together.
Does alcohol in the product matter?
This is the alcohol-free version, so there's no ethanol. However, research shows that lemon balm used with alcohol doesn't affect reaction time or cognitive performance anyway.
