HelloPharmacist Scorecard of Lavender by doTERRA

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.

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: lavender flower. Lavender is the whole flower used in traditional and clinical preparations for conditions ranging from anxiety to pain.

The product has no other inactive ingredients listed.

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: Relaxation, aromatherapy, and topical skin support.
  • We looked for evidence on: Stress, Insomnia, Perioperative anxiety, Pre-procedural anxiety, Pruritus, Atopic dermatitis (eczema) — and 4 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 Burns, Atopic dermatitis (eczema), Insomnia, Stress, and more.

The evidence for lavender is mixed. It's rated possibly effective for dysmenorrhea (menstrual pain).

For cancer-related pain, it's rated possibly ineffective. For alopecia areata (patchy hair loss), pre-procedural anxiety, and cancer-related fatigue, there isn't enough reliable evidence to say whether it works.

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.

Orally, lavender flower is generally well tolerated in food amounts and appears well tolerated at larger doses too. The most common side effects you might notice are breath odor, constipation, diarrhea, indigestion, belching, headache, and nausea.

Topically, it's usually well tolerated, though allergic skin reactions can happen with the oil. There are rare reports of gynecomastia (breast tissue enlargement) in young boys exposed to lavender oil.

Because safety data are limited outside approved forms, use medicinal amounts only with your doctor's guidance. If you're pregnant or breastfeeding, there isn't enough reliable data on file to know either way — talk with your doctor or pharmacist about whether it's right for you.

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 before combining with CNS depressants — sedating medications like sleep aids, anti-anxiety drugs, and opioids. Lavender may increase both their therapeutic effects and side effects.

The bottom line

Scorecard at a glanceFully disclosed formula with no established evidence rating for its marketed use. Moderate medication interactions have been identified, and safety information is well characterized.

doTERRA Lavender may help with menstrual pain, though evidence for other common uses like anxiety is still uncertain. Its main caution is with sedating medications — lavender might strengthen their effects.

If you take any CNS depressants or have questions about how this fits your health picture, check with your doctor or pharmacist first.

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 Lavender by doTERRA interact with any medications?
Yes. Based on its ingredients, 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?
Lavender 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.
Does lavender work for anxiety?
The evidence isn't established in our data. While lavender has shown sedative effects in lab research, clinical trials haven't confirmed it works reliably for pre-procedural anxiety. Talk with your healthcare provider about whether it might help your situation.
What are the side effects of taking lavender orally?
Most people tolerate it well, but you might notice breath odor, constipation, diarrhea, indigestion, belching, headache, or nausea. These aren't common, but they're the ones reported in studies.
Is lavender oil safe to swallow in this product?
Essential oil is toxic if swallowed, so make sure you're using only the approved form your brand provides. If you have any doubt about how to use this product safely, check the label or ask your pharmacist.
Can I use this if I'm taking a sleep aid?
Not without checking first. Lavender may strengthen the effects of sedating medications, so your doctor or pharmacist needs to know before you combine them.
What does this product contain besides lavender?
