HelloPharmacist Scorecard of Lavender Flower 450 mg by TerraVita Premium Collection

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.

This product contains one active ingredient: lavender flower at 450 mg per capsule. Lavender is a flowering plant traditionally used to support relaxation and ease certain types of discomfort.

The capsule also contains gelatin and water as inactive ingredients.

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 Lavender's overall clinical evidence instead.

Moderate

Some clinical evidence supports Lavender 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 ingredient's overall clinical evidence instead.
  • On file: Dysmenorrhea — rated "Possibly Effective" (Natural Medicines).

The evidence for lavender's effectiveness varies by use. It's rated possibly effective for period pain (dysmenorrhea).

For other common reasons people try it—like cancer-related pain, hair loss (alopecia areata), anxiety before a procedure, and cancer-related fatigue—the evidence either isn't strong enough to rate it or suggests it may not work. If you're considering this product for a specific concern, talk it over with your doctor or pharmacist to see whether it's a reasonable choice for you.

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 flower taken by mouth is generally well tolerated, even at larger amounts. The most common side effects reported are mild: breath odor, constipation, diarrhea, indigestion, belching, headache, and nausea.

A few people report headache, and there's a rare report of gynecomastia (breast tissue growth in prepubertal boys) with lavender oil use. One important caution: lavender essential oil is toxic if swallowed, so stick to the flower form, not the concentrated oil.

The safety data for medicinal amounts of lavender isn't extensive, so use it only with your doctor's approval. Pregnancy and lactation safety information is not on file for this ingredient—talk with your healthcare provider if you're pregnant or nursing and want to use this product.

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, check with your doctor or pharmacist if you take CNS depressants—drugs that slow your central nervous system, such as sedatives, sleep aids, anti-anxiety medications, or opioid pain relievers. Lavender may increase both the desired and unwanted effects of these drugs.

No other major medication interactions are documented for the lavender 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.

Lavender Flower 450 mg is generally well tolerated and has some evidence supporting its use for period pain. If you take a CNS depressant (sleeping pill, sedative, or anti-anxiety medication), check with your doctor or pharmacist before adding this product, since lavender might strengthen those effects.

For other uses, the evidence is limited or insufficient to rate. Discuss with your own healthcare provider whether it's right for your situation.

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 450 mg by TerraVita Premium Collection: Common Questions

Does Lavender Flower 450 mg by TerraVita Premium Collection interact with any medications?
Yes. Based on its ingredients, Lavender Flower 450 mg 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 450 mg 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.
Is lavender safe to take if I'm pregnant or nursing?
Safety data for medicinal amounts of lavender during pregnancy and breastfeeding isn't on file. Talk with your doctor or pharmacist for personalized advice before using this product if you're pregnant or nursing.
What side effects might I notice?
Most common side effects are mild: breath odor, constipation, diarrhea, indigestion, belching, headache, and nausea. These are not common in everyone. If you notice anything concerning, stop taking it and talk to your pharmacist.
Does this really help with anxiety or sleep?
The evidence for lavender and pre-procedural anxiety or other types of anxiety isn't strong enough to rate—we don't have enough reliable clinical data yet. If you're looking for help with sleep or anxiety, your doctor or pharmacist can discuss whether this is the right choice for you.
Can I take this with my sleep medication?
That depends on which one you take. Lavender may strengthen the effects of CNS depressants (sleep aids, sedatives, and anti-anxiety drugs), so check with your doctor or pharmacist before combining them.
What is lavender flower, and how is it different from lavender oil?
This product is the dried lavender flower itself, which is safe to take by mouth at the dose in this capsule. Lavender essential oil is concentrated and toxic if swallowed, so never take it that way—stick to the flower or oil-based supplements designed for oral use.
