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: a liquid extract of certified organic California Poppy (the dried above-ground parts of Eschscholzia californica). The extract is suspended in menstruum, an inactive ingredient that serves as the carrier liquid.

Does it work?

Couldn't assess
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 assessable

This is a single-ingredient California Poppy product and its label doesn't state a use — see California Poppy's own graded uses on its monograph.

Why this rating?
  • We looked at the product name, claims, and label statements and couldn't find a stated purpose to grade.

The evidence for California Poppy isn't established yet. The data we hold shows insufficient reliable evidence to rate it for anxiety, insomnia, or nocturnal enuresis (bedwetting).

That doesn't mean it doesn't work — it means the research so far hasn't been solid enough to say one way or the other. If you're thinking about it for one of these uses, ask your doctor what the current research looks like and whether it might fit your situation.

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. The most common side effects reported in studies where it was combined with hawthorn and magnesium included morning fatigue, muscular stiffness, and nausea — though it's unclear whether these came from California Poppy itself, the other ingredients, or the combination.

During pregnancy and breastfeeding, the safety data aren't there yet. The facts advise against use in both cases because we don't know enough.

Talk with your doctor or pharmacist if you're pregnant, planning pregnancy, or breastfeeding and considering this supplement.

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 you take California Poppy, double-check if you're on any CNS depressants — sedatives, sleep aids, anxiety medications, or strong pain relievers. This is a Moderate-severity interaction, and the supplement may boost drowsiness and sedation.

Talk with your doctor or pharmacist if you're on any of these.

The bottom line

Scorecard at a glanceFully disclosed formula with no assessable stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

California Poppy may be worth a conversation if you're looking for a mild herbal approach to sleep or anxiety — but the evidence to support it isn't solid yet. The key concern is combining it with sedative drugs (prescription sleep aids, anti-anxiety meds, or strong pain relievers).

If you take any CNS depressant, check with your doctor or pharmacist before adding this, since the combined effect could be stronger than either alone. Pregnancy and breastfeeding are off-limits based on current safety data.

California Poppy by Herbal Terra: Common Questions

Does California Poppy by Herbal Terra interact with any medications?
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.
Does California Poppy actually help with sleep?
The evidence isn't established yet. We have insufficient reliable data to say whether it works for insomnia. That's different from saying it doesn't work — it means the research so far hasn't been strong enough to confirm it. Talk with your doctor if you're trying it for sleep, especially if you're already on a prescription sleep aid.
What side effects should I watch for?
Information is limited. The most commonly reported effects in studies where it was mixed with hawthorn and magnesium were morning fatigue, muscular stiffness, and nausea — though it's not clear if California Poppy alone caused them. Since human safety data are limited overall, keep an eye out for any unusual drowsiness or stomach upset and let your doctor know.
Is it safe to take if I'm pregnant or breastfeeding?
No. The safety data aren't there yet, and the facts advise against it in both cases. Talk with your doctor or pharmacist if you're pregnant, planning pregnancy, or breastfeeding and want to discuss herbal options.
What's in this formula besides California Poppy?
The active ingredient is a liquid extract of California Poppy. Menstruum — the liquid carrier — is the only other ingredient listed. There are no added fillers or binders.
Can I take this with my sleep medication?
Not without checking first. California Poppy is sedating, and combining it with prescription sleep aids or other CNS depressants could amplify drowsiness. Talk with your doctor or pharmacist before adding it to your routine — they can tell you if it's safe for your specific medications.
