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.

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.

This product contains one active ingredient: California poppy liquid extract. It's made with certified organic grain alcohol and distilled water as inactive ingredients to deliver the extract.

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: California poppy herbal extract.
  • We looked for evidence on: Anxiety, Insomnia, Nocturnal enuresis, Nervousness, Sleep quality, 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, Nocturnal enuresis.

The evidence we hold doesn't establish that California poppy works for anxiety, insomnia, or bedwetting. The safety data available is too limited to say whether it's effective for these purposes — we'd need more human research to know.

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, so we don't have a full picture yet. The safety data advises against use during pregnancy and while breastfeeding — there isn't enough information to know either way, and your doctor or pharmacist should weigh the risks and benefits for your situation.

When used on its own, there's limited information about side effects. In studies where it was combined with hawthorn and magnesium, some people reported muscular stiffness, morning fatigue, and nausea — though it's unclear whether those came from California poppy itself, the other herbs, or the combination.

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.

If you take any CNS depressants (sedating medications like sleep aids, anti-anxiety drugs, or pain relievers with sedative effects), check with your pharmacist or doctor before using this product — California poppy may increase drowsiness.

The bottom line

Scorecard at a glanceFormula with limited ingredient disclosure 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 exploring herbal options for sleep or anxiety, but the evidence isn't established yet. If you take any sedating medications — sleep aids, anxiety drugs, pain relievers, or antihistamines — check with your pharmacist or doctor before adding this.

Talk it over with them to make sure it fits your situation.

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.

What side effects should I watch for?
There's limited information about side effects from California poppy alone. In studies where it was combined with hawthorn and magnesium, some people reported muscular stiffness, morning fatigue, and nausea — though it's unclear if those came from California poppy itself or the other ingredients.
