HelloPharmacist Scorecard of Lemon Balm 475 mg by Solaray

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: lemon balm (Melissa officinalis), a leafy herb traditionally used to ease stress and support mood. It's supplied as a 475 mg capsule.

The capsule also contains inactive ingredients—cellulose (a plant fiber), magnesium stearate (a flow agent), and rice extract blend—which help bind and deliver the herb but are not therapeutic.

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: herbal support.
  • We looked for evidence on: Anxiety, Stress, Insomnia, Dyspepsia, Herpes labialis (cold sores), nervousness — and 2 related terms.
  • The strongest evidence on file: Lemon Balm is rated "Possibly Effective" for Herpes labialis (cold sores) (Natural Medicines).
  • Also on file: Lemon Balm is rated "Possibly Effective" for Stress.
  • Also on file: Lemon Balm is rated "Insufficient Reliable Evidence To Rate" for Anxiety, Dyspepsia, Insomnia.

Lemon balm is possibly effective for herpes labialis (cold sores) and possibly effective for stress and depression, according to the evidence we hold. That means some clinical studies support its use for these purposes, but the evidence isn't definitive enough to call it proven.

If you're considering it for another condition, the data we have doesn't address that.

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, though high doses and long-term safety haven't been thoroughly studied. A small number of trial participants reported dizziness or sedation, but these occurred no more often than with placebo.

One case reported heart rhythm changes (transient complete atrioventricular block and QT prolongation) in a 25-year-old using a multi-ingredient product containing lemon balm, but it's unclear whether lemon balm alone was responsible; symptoms resolved within 24 hours of stopping the product. 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 or pharmacist before use. Topically, a 1% cream applied to cold sores caused irritation or worsening in a few cases, but not more often than placebo.

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, check with your pharmacist if you're on CNS depressants (sedatives, sleep aids, narcotic painkillers, or any drug that makes you drowsy) or thyroid hormone replacement therapy. Both interactions are Moderate in severity and could affect how well your medications work or how you feel.

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, though the evidence is still developing. If you take sedatives, sleep aids, pain relievers that cause drowsiness, or thyroid hormone replacement, check with your pharmacist first—lemon balm could potentiate the former and interfere with the latter.

Pregnant or breastfeeding individuals should talk to their doctor before use.

Formula

True herbs

Discussion: Indigenous to the mountain regions of southern Europe, lemon balm is now a common plant found in gardens everywhere. There is an old myth that this fragrant herb attracts honey bees more than other plants, giving it the nickname of "bee balm." The flavorful leaves enjoy culinary appreciation, especially in the form of a refreshing tea. In Medieval times, drinks with lemon balm were thought to comfort the heart and lift the spirits.

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 475 mg by Solaray: Common Questions

Does Lemon Balm 475 mg by Solaray interact with any medications?
Yes. Based on its ingredients, Lemon Balm 475 mg 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 475 mg 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 CNS depressant activity, so it could theoretically add to drowsiness if you're on sleep aids or sedatives. In clinical trials, a small number of participants reported dizziness or sedation, but it didn't happen more often than placebo. If you're sensitive to drowsiness or take medications that cause it, mention this product to your pharmacist.
Can I take this while I'm on thyroid medication?
Possibly not without checking first. Lab and animal studies show lemon balm constituents can interfere with thyroid hormone signaling and may lower thyroid hormone levels, which could reduce your medication's effectiveness. Talk to your doctor or pharmacist before adding this to your regimen if you take thyroid replacement therapy.
Is lemon balm safe during pregnancy?
There isn't enough reliable safety data to say yes. It's best avoided during pregnancy unless your doctor advises otherwise. If you're pregnant or planning to be, check with your doctor before using.
Can I use this while breastfeeding?
Limited safety information exists for breastfeeding, so use caution. Talk to your doctor or pharmacist before using while breastfeeding—they can help you weigh the potential risks and benefits for your situation.
What is lemon balm actually used for?
According to clinical evidence, lemon balm is possibly effective for cold sores (oral herpes), stress, and depression. It's an herb that has been used traditionally to ease tension and support mood. If you're interested in it for another purpose, that evidence may not be on file.
How long have these capsules been studied for safety?
Lemon balm is generally well tolerated for short-term use in healthy adults, but high doses and long-term safety haven't been thoroughly studied. If you're thinking of taking it long-term, that's another good reason to check in with your pharmacist.
