HelloPharmacist Scorecard of California Poppy Flower by Cedar Bear

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 1 active ingredient.
  • “Proprietary Blend” is a proprietary blend — the label gives one combined amount (0.50 mL) without saying how much of each component you get.

This is a one-ingredient liquid supplement: California poppy. The herb itself is the active component.

The remaining ingredients are vegetable glycerin and purified water, which serve as the base for the liquid formulation.

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, sleep, and nervous tension 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 is limited. For anxiety, insomnia, and nocturnal enuresis (bedwetting), we don't have enough reliable research to say whether it works.

The data we hold doesn't establish that it's effective for these uses, so if you're considering it for one of those reasons, talk with your doctor or pharmacist about what the research actually supports and what other options might be better studied.

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. In a small number of trial reports where it was combined with hawthorn and magnesium, some people reported muscular stiffness, morning fatigue, and nausea — though it's unclear whether those effects came from California poppy itself, the other ingredients, or the combination.

Safety data during pregnancy and breastfeeding are insufficient; the available information advises against use during both.

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 California Poppy Flower, double-check any sedative or CNS depressant medications with your doctor or pharmacist — this includes sleep aids, anti-anxiety drugs, pain relievers that cause drowsiness, and similar medications. California poppy can strengthen their sedative effects (Moderate severity).

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.

California poppy may appeal to you if you're looking for a mild herbal option for relaxation, but the evidence for anxiety or sleep isn't established in our data. Because it interacts with sedative medications (Moderate severity), you'll need to check your exact prescriptions with your doctor or pharmacist before starting.

If you're pregnant or breastfeeding, the safety data suggest avoiding it.

California Poppy Flower by Cedar Bear: Common Questions

Does California Poppy Flower by Cedar Bear interact with any medications?
Yes. Based on its ingredients, California Poppy 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?
California Poppy 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.
Can I take this if I'm on a sleep aid or anti-anxiety medication?
Not without checking first. California poppy can strengthen the sedative effects of those medications, which is a Moderate-level interaction. Talk with your doctor or pharmacist about your specific medications — they can tell you whether it's safe to combine them or whether you need to space them out differently.
Does California poppy actually help with sleep or anxiety?
The evidence isn't there yet. We don't have enough reliable research to say whether it works for insomnia or anxiety. If you're looking for something proven to help, ask your doctor or pharmacist what options have better evidence behind them.
Is it safe during pregnancy or breastfeeding?
No. The safety data advise against using it during pregnancy and while breastfeeding because there isn't enough information to know it's safe. Talk with your doctor or pharmacist if you're in either situation and looking for support.
What side effects should I watch for?
Information about side effects is limited. In reports where California poppy was combined with other herbs (hawthorn and magnesium), some people noted muscular stiffness, morning fatigue, and nausea — though it's unclear what caused them. Because human safety data are scarce, use it only for short periods and let your doctor know if anything feels off.
What is California poppy used for?
It's traditionally used for relaxation and sleep support, but we don't have reliable evidence it works for anxiety, insomnia, or bedwetting. It does have sedative properties, which is why it can interact with sedative medications.
