HelloPharmacist Scorecard of Essence of Lavender by North American Herb & Spice

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 2 active ingredients.
  • “Proprietary Blend” is a proprietary blend — the label doesn't break down how much of each component you get.

This 2-ingredient liquid contains a proprietary blend (we don't have the individual breakdown of that mix) and spring water, plus lavender. Lavender is the active ingredient here; it's been used traditionally for relaxation and sleep, though the science on what it actually does is still being filled in.

Does it work?

Not established
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
Not established

The graded evidence we hold for these ingredients covers different conditions than the ones this product is marketed for, so there's no established rating for its stated use — see Lavender's own graded uses on its monograph.

Why this rating?
  • The label markets this product for: Supports a healthy nervous system.
  • We looked for evidence on: Stress, Perioperative anxiety, Pre-procedural anxiety, Insomnia, Psychological well-being, Anxiety — and 2 related terms.
  • The closest evidence on file: Lavender is rated "Insufficient Reliable Evidence To Rate" for Pre-procedural anxiety (Natural Medicines).
  • Also on file: Lavender is rated "Insufficient Reliable Evidence To Rate" for Insomnia, Stress, Psychological well-being, Perioperative anxiety.

For period pain (dysmenorrhea), lavender is possibly effective. For cancer-related pain, the evidence suggests it's probably not helpful.

For hair loss (alopecia areata), pre-procedural anxiety, and cancer-related fatigue, we don't have enough reliable evidence in our data to say whether it works or not.

The evidence, ingredient by ingredient Lavender

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.

Taken by mouth in food amounts or larger amounts, lavender is generally well tolerated. Topical lavender oil also tends to be well tolerated, though allergic skin reactions can happen.

The most common oral side effects in people who've tried it are breath odor, constipation, diarrhea, upset stomach, burping, headache, and nausea. Topically, there's a rare case report of breast tissue growth in young boys using lavender oil — this is uncommon but worth knowing.

Because safety data is limited, don't use medicinal amounts unless your doctor approves. Essential oil swallowed whole is toxic, and skin contact can irritate some people.

Side effects, ingredient by ingredient Lavender

Moderate interaction found
Known Interaction Concern · database check

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 — Lavender.
  • The most serious interaction on file is rated Moderate.
  • For scale: 248 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 against this product if you take CNS depressants — sedatives, sleep aids, anti-anxiety drugs, or certain pain relievers. Lavender may boost both the effects and side effects of these drugs.

The bottom line

Scorecard at a glanceFormula with limited ingredient disclosure with no established evidence rating for its marketed use. Moderate medication interactions have been identified, and safety information is well characterized.

If you take sedating medications or drugs that slow your central nervous system, check with your pharmacist before adding this. Lavender seems well tolerated overall, but the science on whether it actually works for most conditions is still incomplete.

Cns Depressants

Theoretically, lavender might potentiate the therapeutic effects and adverse effects of CNS depressants.
Laboratory research suggests that lavender has sedative effects. However, clinical studies in patients taking oral lavender oil (Silexan) 160 mg for 10 weeks or taking lavender flower powder 1 gram daily for 2 months have not reported side effects of drowsiness, sedation, or sleepiness. There is still some concern that higher doses or different preparations of lavender might have additive effects with CNS depressant medications.

Does Essence of Lavender by North American Herb & Spice interact with any medications?
Yes. Based on its ingredients, Essence of Lavender has a known interaction with 248 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Essence of Lavender 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 pregnant or nursing?
The safety data for lavender in pregnancy and breastfeeding isn't on file in our system. Because the evidence isn't established, talk with your doctor or pharmacist about whether it's right for you.
What are the most common side effects?
By mouth, the most common ones are breath odor, constipation, diarrhea, upset stomach, burping, headache, and nausea. Most people tolerate it fine, but these can happen.
Is the essential oil in this product safe to swallow?
No — pure essential oil is toxic if swallowed. This is a liquid lavender product, so check the label to confirm what form you're taking and use it only as directed.
Will this help with anxiety before a medical procedure?
We don't have enough reliable evidence in our data to say whether lavender actually works for pre-procedural anxiety. The research isn't settled yet.
Can topical lavender oil cause skin problems?
Most people tolerate it fine, but allergic contact dermatitis (a skin reaction) can happen with lavender oil on the skin. Patch-test first if your skin is sensitive.
