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

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 liquid contains one active ingredient: California poppy. It's prepared in a base of vegetable glycerin and purified water.

California poppy has a long history in herbal medicine, traditionally used for relaxation and sleep support, though the strength of evidence for those purposes is limited.

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: calm anxiety and support sleep.
  • We looked for evidence on: Anxiety, Insomnia, nervous tension, 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 well enough to rate it reliably for anxiety, insomnia, or bedwetting (nocturnal enuresis). We simply don't have sufficient quality research to say whether it works for these uses.

If you're considering it for one of these reasons, talk with your doctor or pharmacist about what the data actually supports and what alternatives might work better.

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. When taken alone, side effects haven't been well documented.

In studies where it was combined with hawthorn and magnesium, some people reported morning fatigue, nausea, and muscular stiffness — though it's unclear whether California poppy, the other ingredients, or the combination caused these effects. There isn't enough safety data to use this product during pregnancy or while breastfeeding.

If you're pregnant, nursing, or planning to become pregnant, talk with your doctor or pharmacist before taking it.

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, check with your doctor or pharmacist if you take any sedatives, sleep aids (like benzodiazepines), anti-anxiety drugs, or other medications that cause drowsiness. California poppy can increase sedative effects and may amplify the impact of these drugs.

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 Flower is traditionally used to support relaxation and sleep, but we don't have strong evidence it works for anxiety or insomnia. The main caution is combining it with medications that make you drowsy — that's a real interaction risk.

Talk with your doctor or pharmacist about whether it fits your needs and whether it's safe with your other medications.

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 pregnant or breastfeeding?
There isn't enough safety data to know whether California poppy is safe during pregnancy or while breastfeeding. The safety information advises against it. Talk with your doctor or pharmacist about personalized advice for your situation.
What side effects might I experience?
Human safety data are limited, so we don't have a clear picture of common side effects when California poppy is used alone. In research where it was combined with other herbs, some people reported morning fatigue, nausea, and muscular stiffness, though it's unclear what caused them. Most adverse effects haven't been well documented.
Does California poppy actually work for sleep or anxiety?
The evidence isn't strong enough to reliably say whether it works for anxiety, insomnia, or bedwetting. We simply don't have sufficient quality research to rate its effectiveness for these uses. If sleep or anxiety is your goal, discuss other options with your doctor or pharmacist.
Can I take this with my sleep medication?
Not without checking first — California poppy can increase sedative effects when combined with sleep aids and other drugs that slow down your nervous system. The result could be more drowsiness than either one alone. Talk with your pharmacist or doctor before combining them.
