HelloPharmacist Scorecard of Lemon Balm Leaf Powder by TerraVita Premium Collection

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 one active ingredient: lemon balm powder. Lemon balm is a plant from the mint family; the powder here is made from its leaves.

There are no other active ingredients and no inactive fillers listed for this product.

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 rated possibly effective for cold sores (herpes labialis) and possibly effective for stress and depression. That means the evidence we have suggests it may help with these, but the research isn't conclusive enough yet to promise it will work for you.

If you're thinking about using it for one of these reasons, talk it over with your doctor or pharmacist to see if it makes sense for 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 powder is generally well tolerated when used short-term in healthy adults, but we don't have solid data on high doses or long-term safety. In studies, dizziness and sedation have been reported, though they didn't occur more often than with placebo.

One unusual case reported a heart rhythm abnormality in a woman using a product containing lemon balm (along with other ingredients), but it's unclear whether lemon balm itself was responsible. 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 it. If you apply lemon balm cream directly to cold sores, rare cases of local irritation have been reported, though again this didn't happen more often than with 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, double-check with your doctor or pharmacist if you take CNS depressants (sleep aids, anti-anxiety medications, opioids, sedating antidepressants, or similar brain-slowing drugs) or thyroid hormone replacement therapy. Both are Moderate-severity concerns with lemon balm.

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.

Lemon balm powder may be worth considering if you're interested in possibly easing stress, depression, or cold sores and your doctor thinks it's appropriate for you. Be cautious if you take sleep aids, anti-anxiety medications, opioids, or thyroid replacement therapy — the interactions we have data on are moderate concerns.

Talk with your own doctor or pharmacist before you start, especially if you're pregnant, breastfeeding, or taking any regular medications.

Lemon Balm, Powder2 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.

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.
Can I take lemon balm powder while I'm pregnant?
No — there isn't enough reliable safety data to recommend it during pregnancy. It's best avoided unless your doctor says otherwise. Talk to your doctor before starting it.
