HelloPharmacist Scorecard of Lemon Balm 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

Generated from HelloPharmacist’s pharmacist-curated databases and editorial rules · Last generated Aug 13, 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 a single active ingredient: lemon balm herb in liquid form. The inactive ingredients are organic alcohol and 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: support the nervous system.
  • 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 cold sores (herpes labialis), stress, and depression based on the evidence we hold. That means there's some research support, but it's not definitive — more study would strengthen the case.

For any of these uses, talk with your doctor about 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 most healthy adults, though long-term safety and high-dose effects haven't been thoroughly studied. The most commonly reported side effects are dizziness and sedation, but these didn't show up more often than placebo in clinical trials.

During pregnancy, there isn't enough reliable safety data, so it's best avoided unless your doctor advises otherwise. While breastfeeding, limited safety information exists — talk with your doctor or pharmacist before using it.

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 take this, double-check thyroid hormone replacement therapy with your doctor or pharmacist — lemon balm may theoretically reduce how well it works. Also flag any CNS depressants (sedating medications like sleep aids, anti-anxiety drugs, or opioid pain relievers) you're on, since lemon balm could add to their sedating effects.

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, stress, or low mood, but the evidence is preliminary. If you're on thyroid medication or take sedating drugs, check your exact medications before starting.

Pregnant people should avoid it unless their doctor says otherwise, and those breastfeeding should talk it over first. Chat with your doctor or pharmacist about whether this fits your needs.

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.
