HelloPharmacist Scorecard of California Poppy by Herbal Terra

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 Seed Extract (dry form). California poppy is a plant traditionally used to support relaxation and sleep.

The liquid also contains alcohol, water, and glycerin 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: Supports relaxation and restful sleep.
  • We looked for evidence on: Anxiety, Insomnia, Stress, 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 doesn't establish that California poppy works for anxiety, insomnia, or bedwetting (nocturnal enuresis). The data we have rates these uses as insufficient reliable evidence to rate — meaning studies haven't yet shown it's effective for those purposes.

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, though human safety data are limited. The most common reported side effects — when used alongside other herbs (hawthorn and magnesium) — were muscular stiffness, morning fatigue, and nausea; it's unclear whether California poppy alone caused these or the combination did.

The safety data advise against use during pregnancy and breastfeeding because there isn't enough information to know whether it's safe.

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.

Check before you start if you take any CNS depressants — sedatives, sleep aids, anti-anxiety medications, or anything with a sedative effect. California poppy may increase drowsiness and sedation with these drugs.

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 appeal to you if you're exploring herbal options for sleep or relaxation, but the evidence for effectiveness isn't established in our data. If you take any sedating medications — sleep aids, anxiety drugs, or anything that makes you drowsy — talk with your pharmacist before adding this product.

Pregnancy and breastfeeding aren't supported by the available safety information, so check with your doctor or pharmacist if that applies to you.

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.
