HelloPharmacist Scorecard of Lavender Flower by TerraVita

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 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 Glycerite Liquid Extract. The glycerin is an inactive carrier used to deliver the lavender.

Glycerite extracts are alcohol-free alternatives to traditional tinctures, making them suitable for people who prefer to avoid alcohol or who cannot tolerate it.

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: lavender flower extract for relaxation and calming.
  • We looked for evidence on: Insomnia, Perioperative anxiety, Pre-procedural anxiety, Stress, Psychological well-being, sleep quality — 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, Psychological well-being, Perioperative anxiety.

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

For cancer-related pain, it's rated possibly ineffective. For other uses listed here — hair loss (alopecia areata), pre-procedural anxiety, and cancer-related fatigue — there isn't enough reliable evidence yet to know whether it works.

If you're considering lavender for one of these conditions, talk with your doctor about whether the current evidence supports trying it for your specific situation.

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 in food amounts and larger oral doses is generally well tolerated. The most common side effects reported orally are breath odor, constipation, diarrhea, heartburn (dyspepsia), burping, headache, and nausea.

When applied to skin, lavender oil is also generally well tolerated, though allergic contact dermatitis (rash) can occur in some people. Rare cases of enlarged breast tissue have been reported in prepubertal boys using lavender oil topically.

The facts note that safety data for lavender is not comprehensive, and the product recommends avoiding medicinal amounts unless your doctor approves. If you're pregnant or breastfeeding, there isn't enough reliable information on file here to say whether lavender is safe — talk with your doctor or pharmacist for personalized guidance.

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 — 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.

Before taking this product, double-check any CNS depressants (sedatives, sleep aids, anti-anxiety medications, opioid pain relievers, antihistamines, and alcohol) with your doctor or pharmacist. Lavender may strengthen the sedating effects of these drugs, making you drowsier or amplifying side effects.

No other medication interactions are documented in our data for this ingredient.

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.

Lavender glycerite may help with period pain, and it's generally well tolerated at typical doses. However, it can amplify the effects of sedating medications and CNS depressants — a moderate-risk interaction affecting many common drugs.

Before you start, check your medications against the tool on this page, especially if you take sleep aids, anxiety meds, opioids, or drink alcohol regularly. Your doctor or pharmacist can help you decide whether it's right for you.

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.

Lavender Flower by TerraVita: Common Questions

Does Lavender Flower by TerraVita interact with any medications?
Yes. Based on its ingredients, Lavender Flower 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 Flower 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.
What's the difference between this glycerite and lavender oil or tea?
This is a glycerite extract — the active compounds from lavender flower dissolved in glycerin (a sweet liquid) instead of alcohol or water. Glycerites are alcohol-free and gentler on the stomach for some people. Lavender essential oil is a concentrated volatile extract and is toxic if swallowed, which is why this product uses a safer extract form.
Will this help with my anxiety?
There isn't enough reliable evidence yet to say whether lavender works for pre-procedural (before a medical procedure) or general anxiety. If you're interested in trying it, talk with your doctor about whether it makes sense for your situation, especially if you take any anxiety or sleep medications.
Can I take this if I'm pregnant or breastfeeding?
There isn't enough reliable safety data on file to know whether lavender is safe during pregnancy or while breastfeeding. Talk with your doctor or pharmacist before starting — they can review the latest evidence and give you personalized advice for your situation.
What side effects should I expect?
Most people tolerate lavender well. The most common side effects reported are mild: breath odor, constipation or diarrhea, heartburn, burping, headache, and nausea. Serious side effects are rare. If you notice anything unusual, stop and talk with your doctor or pharmacist.
Is it safe to take this with my sleep medication?
Not without checking first. Lavender may strengthen the sedating effects of sleep aids and other CNS depressants, which could make you much drowsier than intended. Talk with your doctor or pharmacist before combining them — they can tell you whether it's safe for you.
