HelloPharmacist Scorecard of Lavender 4:1 Extract Powder 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.
What’s inside
Full disclosure
This product contains one active ingredient: lavender extract in powder form, concentrated at a 4:1 ratio (meaning four parts of the plant are used to make one part extract). There are no inactive ingredients listed.
Does it work?
Insufficient evidence
Lavender extract shows some evidence for dysmenorrhea — period pain — and is rated possibly effective for that use. For cancer-related pain, the evidence suggests it's possibly ineffective.
The data we hold shows insufficient reliable evidence to rate lavender for hair loss (alopecia areata), anxiety before procedures, or cancer-related fatigue, meaning we don't yet have enough solid studies to say whether it works for those.
How safe is it?
Well-documented data
Orally, lavender powder and extracts are generally well tolerated in food amounts and appear well tolerated in larger medicinal doses. The most common side effects reported are breath odor, constipation, diarrhea, indigestion, belching, headache, and nausea — and these are mild.
Serious side effects are rare. However, the safety data for medicinal amounts isn't extensive, so you should only use it with your doctor's approval if you're pregnant, nursing, or have specific health concerns.
Essential lavender oil is toxic if swallowed, and skin contact can irritate some people — but this product is a powder extract, not the essential oil.
Meds to double-check
Moderate interaction found
Before you take this lavender powder, double-check any CNS depressants — sedatives, sleeping pills, anti-anxiety medications, and similar drugs that slow brain activity. A moderate interaction is documented, meaning lavender could boost both the intended calming effect and side effects like drowsiness.
Your own doctor or pharmacist can review your specific medications and advise whether it's safe to combine them.
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.
Lavender extract powder may help with period pain, though evidence for other uses is unclear or insufficient. It pairs cautiously with CNS depressants like sleep aids and anti-anxiety medications — the combination could make drowsiness stronger.
Talk with your doctor or pharmacist before adding this to your routine, especially if you take any sedating medications or have safety questions about your individual situation.

HelloPharmacist Interaction Report
TerraVita Premium Collection Lavender 4:1 Extract Powder contains lavender extract, which interacts with CNS depressants — medications that slow down brain activity, such as sedatives, sleeping pills, and anti-anxiety drugs.
Lavender may amplify both the therapeutic effects and side effects of these medications, meaning your sedation could be deeper or last longer than expected, and drowsiness or dizziness could be more pronounced.
Read the full breakdown — every affected drug type, severity by severity
Laboratory research shows lavender has sedative properties, but clinical trials in patients taking oral lavender supplements for up to 10 weeks haven't reported serious problems. Still, the interaction is documented as a moderate concern.
Altogether, these interactions span 248 individual medications.
Before you start this powder, check your exact medications — especially any that make you drowsy or are meant to calm you down — with your doctor or pharmacist. They can tell you whether combining them is okay or if you need to adjust timing or doses.

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.
