HelloPharmacist Scorecard of Lavela WS 1265 by Integrative Therapeutics

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.

Lavela WS 1265 is a single-ingredient softgel: English lavender oil (from Lavandula angustifolia), the same plant material studied in clinical trials for anxiety and menstrual pain. The capsule itself contains canola oil, gelatin, glycerin, sorbitol, and annato extract — inactive ingredients that make up the softgel shell and carrier.

Does it work?

Insufficient 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
Insufficient

There isn't enough reliable clinical evidence to rate this product's ingredients for its stated purpose.

Why this rating?
  • The label markets this product for: anxiety, stress, and sleep support.
  • We looked for evidence on: Insomnia, Stress, Perioperative anxiety, Pre-procedural anxiety, relaxation, calming — and 1 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, Perioperative anxiety.

The evidence for lavender in this product is mixed. For dysmenorrhea (menstrual pain), there's possibly effective evidence.

For cancer-related pain, the data suggests it's possibly ineffective. For hair loss, pre-procedural anxiety, and cancer-related fatigue, we don't have enough reliable evidence to say whether it works or doesn't.

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.

Lavender oil taken by mouth is generally well tolerated at food amounts and at larger medicinal amounts. The most common side effects are breath odor, constipation, diarrhea, indigestion, gas, headache, and nausea.

Topically, it's well tolerated for most people, though allergic skin reactions can happen. There's one rare report of breast tissue enlargement in young boys using lavender oil topically, so caution is warranted with children.

The safety data for medicinal amounts isn't extensive, so use this product only under guidance from your doctor or pharmacist. Essential lavender oil itself is toxic if swallowed, but this product is formulated as a measured softgel.

Pregnancy and lactation safety information is not on file for this ingredient — talk with your doctor or pharmacist before using it if you're pregnant or breastfeeding.

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 taking this product if you use CNS depressants — sedatives, sleep aids (like melatonin or zolpidem), anxiety medications, opioid pain relievers, or antidepressants. Lavender may strengthen their calming and sedating effects.

The bottom line

Scorecard at a glanceFully disclosed formula with insufficient evidence for its stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

Lavela WS 1265 might help with menstrual pain, but the evidence for other uses is limited or lacking. The main caution is with sedating medications — lavender can boost their effects.

If you take anything for anxiety, sleep, depression, or pain, check with your doctor or pharmacist before adding this to make sure it won't potentiate your current treatment.

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.

Lavela WS 1265 by Integrative Therapeutics: Common Questions

Does Lavela WS 1265 by Integrative Therapeutics interact with any medications?
Yes. Based on its ingredients, Lavela WS 1265 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?
Lavela WS 1265 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 this help with my anxiety?
The evidence isn't strong enough to say yet — there's insufficient reliable evidence to rate lavender for anxiety before a procedure or for general anxiety. If you're interested in trying it, talk it over with your doctor or pharmacist first, especially since it interacts with anxiety medications.
Can I take this if I'm pregnant or breastfeeding?
We don't have enough safety data on file to say either way. Talk with your doctor or pharmacist before using medicinal amounts of lavender during pregnancy or while breastfeeding — they'll know your full health picture and can help you decide.
What are the most common side effects?
When taken by mouth, the most common ones are breath odor, constipation, diarrhea, indigestion, gas, headache, and nausea. These are usually mild. More serious side effects are rare.
Can I use this if I take a sleeping pill?
Not without checking first. Lavender can amplify the sedating effects of sleep aids, which could make you too drowsy or increase other side effects. Talk with your doctor or pharmacist before combining them.
Is the essential oil in here safe to swallow as-is?
No — pure lavender essential oil is toxic if swallowed. This product is a measured softgel with diluted lavender oil, so it's formulated to be taken as directed. Don't break the capsule open or use straight essential oil.
