HelloPharmacist Scorecard of California Poppy by Herb 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.

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: California poppy whole flowering plant extract. Traditionally used to support calm and sleep, it comes as a liquid extract in a base of certified organic cane alcohol and distilled water.

Does it work?

Not established
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
Not established

The graded evidence we hold for these ingredients covers different conditions than the ones this product is marketed for, so there's no established rating for its stated use — see California Poppy's own graded uses on its monograph.

Why this rating?
  • The label markets this product for: nervous system calming.
  • We looked for evidence on: Anxiety, Insomnia, Restlessness, Nervous tension.
  • 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 we hold rates both anxiety and insomnia as having insufficient reliable data to establish whether California poppy works for these uses. The same applies to nocturnal enuresis (bedwetting).

That doesn't mean it's ineffective—just that we don't yet have solid clinical evidence behind it.

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 considered mild for short-term use, but human safety data are limited. The most common reported side effects from studies come when it's combined with other herbs like hawthorn and magnesium, and include muscular stiffness, morning fatigue, and nausea—though it's unclear whether California poppy alone caused these or if the other ingredients played a role.

There isn't enough safety data to know whether California poppy is safe in pregnancy or while breastfeeding. If you're pregnant or nursing, talk with your doctor or pharmacist before taking it.

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 you take California poppy, check with your doctor or pharmacist if you're on any CNS depressants—sleep aids, benzodiazepines, opioids, or any medication that causes drowsiness. Taking them together can increase sedation.

The bottom line

Scorecard at a glanceFully disclosed formula with no established evidence rating for its marketed use. Moderate medication interactions have been identified, and safety information is well characterized.

California poppy may be worth considering if you're looking for herbal support for anxiety or sleep, but the evidence for its effectiveness isn't firmly established yet. The main caution is combining it with sedative medications—that's something to clear with your own doctor or pharmacist first.

It's also best avoided in pregnancy and breastfeeding unless your healthcare provider advises otherwise.

Yes. Based on its ingredients, California Poppy 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 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 California poppy if I'm pregnant or breastfeeding?
There isn't enough safety data to know either way. It's best avoided in pregnancy and while breastfeeding unless your doctor or pharmacist says otherwise. Talk with them for personalized advice.
What are the side effects?

Does it actually work for anxiety or insomnia?
The evidence we have is insufficient to say for certain. That means there isn't solid clinical proof it works for these uses, though people have traditionally used it for sleep and calm.
Is it safe to use short-term?
California poppy is generally considered mild for short-term use, but human safety data are limited. If you have questions about how long is safe for your situation, check with your doctor or pharmacist.
