HelloPharmacist Scorecard of Olive Leaf Extract 250 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 2 of its 2 active ingredients.
  • No proprietary blends here — you can verify the dose of every single component.

This product contains 2 active ingredients: lemon balm and olive leaf extract. Lemon balm is traditionally used to help with stress and cold sores, while olive leaf extract is included for general wellness support.

The capsule also contains several inactive ingredients — rice concentrate, vegetable cellulose (the capsule itself), maltodextrin, rice extract blend, and silica — which are fillers and binders that help hold the capsule together.

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 its ingredients' overall clinical evidence instead.

Moderate

Some clinical evidence supports its ingredients 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 ingredients' overall clinical evidence instead.
  • On file: Herpes labialis (cold sores) — rated "Possibly Effective" (Lemon Balm) (Natural Medicines).
  • On file: Depression — rated "Possibly Effective" (Lemon Balm) (Natural Medicines).
  • On file: Stress — rated "Possibly Effective" (Lemon Balm) (Natural Medicines).

Lemon balm in this product is possibly effective for cold sores (herpes labialis) and possibly effective for stress and depression, based on available evidence. Olive leaf extract's effectiveness is less clear — the evidence we hold rates it insufficient for osteoporosis, upset stomach, respiratory infections, shingles, flu, and osteoarthritis.

In other words, we don't yet have strong evidence backing olive leaf extract for any of these uses.

The evidence, ingredient by ingredient Lemon Balm Olive

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 2 of the 2 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 2 of 2.
  • General safety write-ups exist for 2 of 2.
  • 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, but high doses and long-term safety haven't been well studied. Reported side effects are rare — some people have experienced dizziness or sedation in clinical trials, but these don't occur more often with lemon balm than with placebo.

One unusual case reported heart rhythm changes (atrioventricular block and QT prolongation) in a person using a multi-ingredient product containing lemon balm, though it's unclear if lemon balm alone was the cause. Olive leaf extract is well tolerated in most people.

The most common side effects reported are headache and stomach discomfort. One trial participant reported acne.

Since concentrated olive leaf supplements are less studied than whole olives and olive oil as foods, the long-term safety picture is still incomplete. During pregnancy, there isn't enough safety data for lemon balm — your doctor should advise whether it's right for you.

For breastfeeding, limited safety information exists, so check with your doctor or pharmacist first. Pregnancy and lactation safety data for olive leaf extract is not on file.

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 2 matched ingredients 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 Solaray Olive Leaf Extract, double-check with your doctor or pharmacist if you're on CNS depressants (sleep aids, sedatives, anti-anxiety drugs, opioids, or any medication that makes you drowsy) or thyroid hormone replacement therapy. Both are Moderate-severity interactions with the lemon balm in this product.

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.

This product may work for you if you're interested in lemon balm's possible effects on stress, mood, or cold sores — the evidence is modest but encouraging. However, if you take sedatives, sleep aids, anti-anxiety medications, opioids, or thyroid hormone replacement, you'll want to check with your doctor or pharmacist before starting, because lemon balm can interact with those drugs.

Talk it over with your own healthcare provider to make sure it's a fit for your situation.

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.

Likelihood Possible Evidence D

Does Olive Leaf Extract 250 mg by Solaray interact with any medications?
Yes. Based on its ingredients, Olive Leaf Extract 250 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?
Olive Leaf Extract 250 mg contains 2 active ingredients, and an interaction can come from any of them. We check every ingredient, combine the results into one list per medication, and show which ingredient and mechanism is 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.
Can I take this while I'm on a sleep aid or anxiety medication?
Not without checking first — lemon balm in this product may add to the drowsiness and sedation from those drugs. Talk to your doctor or pharmacist before combining them.
Does this product have any reported side effects?
Lemon balm may rarely cause dizziness or sedation, and olive leaf extract may cause headache or stomach discomfort in some people. Overall, both are well tolerated, and these effects don't happen more often than with placebo in trials.
Is lemon balm safe during pregnancy?
Not enough reliable safety data exists, so it's best avoided during pregnancy unless your doctor advises otherwise.
Will olive leaf extract actually help me feel better?
The evidence we hold doesn't yet support olive leaf extract for most uses — the data is rated insufficient. Lemon balm in the product is possibly effective for stress, mood, and cold sores, but evidence is modest.
Is this safe long-term?
Short-term use of lemon balm is well tolerated in most healthy adults, but long-term safety hasn't been well studied. Olive leaf extract as a concentrated supplement is also less studied than olives and olive oil as foods. For extended use, check with your doctor or pharmacist first.
