HelloPharmacist Scorecard of Lemon Balm by Tonic Tinctures

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

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: lemon balm leaf tincture — a liquid herbal extract of the lemon balm plant. The inactive ingredients are water, alcohol, and stevia leaf extract.

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).

Lemon balm is possibly effective for cold sores (herpes labialis) and for stress and depression, based on the clinical evidence we have on file. That said, 'possibly effective' means the research shows some promise, not that it's proven to work — more robust studies would be needed to be certain.

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 long-term safety and effects of high doses haven't been well studied. In trials, dizziness and drowsiness were reported, but no more often than with placebo.

A rare case of heart rhythm changes was reported in someone using a multi-ingredient product containing lemon balm, but it's unclear whether lemon balm alone was responsible. Avoid lemon balm during pregnancy unless your doctor advises otherwise — there isn't enough safety data.

If you're breastfeeding, the safety information is limited; talk to your doctor 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.

Check your medications if you take CNS depressants like sleep aids, sedatives, anxiety medication, or pain relievers — lemon balm may boost their drowsy effects (Moderate). Also check if you're on thyroid hormone replacement therapy, as lemon balm may interfere with it (Moderate).

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.

Lemon balm may help with cold sores or stress, but its interaction potential with sedating drugs and thyroid medication means you should check with your pharmacist first. It's not recommended in pregnancy.

If you're taking CNS depressants or thyroid hormone, this product needs a quick verification before you start.

Lemon Balm Leaf Tincture2 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 by Tonic Tinctures: Common Questions

Does Lemon Balm by Tonic Tinctures interact with any medications?
Yes. Based on its ingredients, Lemon Balm 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 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?
Dizziness and drowsiness have been reported with lemon balm, but in clinical trials these effects didn't show up more often than with placebo. However, if you're already taking sedating medications, lemon balm could add to that effect — that's the main concern.
Can I use lemon balm while pregnant?
There isn't enough reliable safety data, so it's best avoided during pregnancy unless your doctor specifically advises you otherwise. If you're considering it, talk to your doctor first.
Is it safe to use lemon balm while breastfeeding?
Safety information is limited. Talk to your doctor before using it while breastfeeding so they can weigh the pros and cons for your situation.
Does lemon balm actually work for cold sores?
Lemon balm is possibly effective for cold sores based on the evidence we have. That means research shows some promise, but it's not a guaranteed cure — you and your doctor can decide if it's worth trying.
Can I use lemon balm long-term?
We don't have solid safety data on long-term use or high doses. It's considered well tolerated for short-term use in healthy adults, so if you're thinking of using it regularly, check in with your pharmacist or doctor.
What's in this tincture besides the lemon balm?
The inactive ingredients are water, alcohol, and stevia leaf extract. The alcohol is part of how the herb is extracted and preserved in liquid form.
