HelloPharmacist Scorecard of California Poppy and Lavender by Hawaii Pharm

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 Jul 16, 2026

What’s inside

Low disclosure
Ingredient Transparency · database check
Low

Most active ingredients don't disclose an individual amount — you can't tell how much of each you're getting.

Why this rating?
  • The label discloses an exact amount for 0 of its 2 active ingredients.
  • “Proprietary Extract Blend” is a proprietary blend — the label gives one combined amount (983 mg) without saying how much of each component you get.

This liquid contains two active ingredients: California poppy extract and lavandin flower extract. California poppy has a history of use for relaxation and sleep support, while lavandin (a hybrid of true lavender) is traditionally used for calming.

The product also includes alcohol, water, and glycerin as inactive ingredients to preserve and deliver the extracts.

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 and sleep support.
  • We looked for evidence on: Anxiety, Insomnia, stress, restlessness.
  • The closest evidence on file: California Poppy is rated "Insufficient Reliable Evidence To Rate" for Anxiety (Natural Medicines).
  • Also on file: California Poppy is rated "Insufficient Reliable Evidence To Rate" for Insomnia.

The evidence for California poppy isn't established enough to make a solid claim. The data we hold rates it insufficient evidence for anxiety, insomnia, and nocturnal enuresis (nighttime bedwetting).

We have no effectiveness information on file for lavandin flower extract.

The evidence, ingredient by ingredient California Poppy

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.

California poppy is generally well tolerated for short-term use, but human safety data are limited. The adverse effects reported in trials — muscular stiffness, morning fatigue, and nausea — came from a combination product with hawthorn and magnesium, so it's unclear whether California poppy alone caused them.

For pregnancy and breastfeeding, the safety data advises against use. There isn't enough information to know it's safe during pregnancy or while breastfeeding; talk with your doctor or pharmacist before using it if you're pregnant, planning pregnancy, or nursing.

Side effects, ingredient by ingredient California Poppy

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 — California Poppy.
  • 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 your medications against the interaction checker below if you take any CNS depressants — that is, sedatives, sleep aids, anti-anxiety drugs, pain relievers, or anything else prescribed to calm or slow your nervous system. The combination could increase sedative effects.

The bottom line

Scorecard at a glanceFormula with limited ingredient disclosure with insufficient evidence for its stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

This product may help with relaxation or sleep, but the evidence isn't strong enough to confirm it works. The main concern is mixing it with sedating medications — CNS depressants — which could boost drowsiness beyond what either would cause alone.

If you take any medications that make you sleepy or calm your nervous system, check with your doctor or pharmacist first. Pregnant or breastfeeding?

Skip this one unless your healthcare provider says otherwise.

California Poppy and Lavender by Hawaii Pharm: Common Questions

Does California Poppy and Lavender by Hawaii Pharm interact with any medications?
Yes. Based on its ingredients, California Poppy and 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?
California Poppy and Lavender contains 2 active ingredients, and an interaction can come from any of them. We check every ingredient, combine the results into one list per medication, and show which ingredient and mechanism is 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 this actually work for sleep or anxiety?
The evidence we hold doesn't support strong claims. Both anxiety and insomnia are rated insufficient reliable evidence — meaning the research isn't solid enough to say either way. It's a traditional remedy, but you won't find proof it works.
Can I take this with my sleep medication?
Not without checking first. California poppy may boost the sedative effect of sleep aids and anti-anxiety drugs, which could make you too drowsy or unsteady. Talk with your doctor or pharmacist before combining them — don't start this on your own.
What side effects should I watch for?
Information is limited, but when California poppy was used with other herbs, some people reported morning fatigue, nausea, and muscle stiffness — though it's unclear if California poppy alone caused them. Any unusual drowsiness, dizziness, or nausea warrants a call to your pharmacist.
Is it safe to use while pregnant or breastfeeding?
No. The safety data advises against use during pregnancy and while breastfeeding. There isn't enough information to know it's safe, so talk with your doctor before taking it if you're pregnant, planning to get pregnant, or nursing.
What's in this — just the herbal extracts?
The active ingredients are California poppy and lavandin flower extracts. The product also contains alcohol, water, and glycerin to preserve and deliver them.
