HelloPharmacist Scorecard of California Poppy by Gaia Herbs

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: organic California poppy whole plant extract. It's prepared as a liquid in a base of alcohol and water, which helps extract and preserve the plant's compounds.

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. We hold insufficient reliable evidence to rate it for anxiety, insomnia, or nocturnal enuresis (bedwetting).

That doesn't mean it doesn't work—it means human studies haven't given us enough solid data to say one way or the other. If you're curious about it for a specific condition, that's a good conversation to have with your doctor or pharmacist.

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. A small number of people using it in combination with hawthorn and magnesium reported muscular stiffness, morning fatigue, and nausea, though it's unclear whether California poppy itself was the culprit or the combination of all three.

There isn't enough safety data to know if it's okay during pregnancy or breastfeeding—the safety data advises against both.

Side effects, ingredient by ingredient California Poppy

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 start, check with your doctor or pharmacist about any CNS depressants you're taking—sedatives, sleep aids, pain relievers, or other drugs that slow down your nervous system. These interactions span 248 individual medications.

The product also contains alcohol, so flagging that with your pharmacist is important too.

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 considering if you're exploring herbal options for anxiety or sleep, but the evidence isn't strong yet. Anyone taking sedative medications or CNS depressants should check with their doctor or pharmacist before adding it.

Pregnant or breastfeeding individuals should talk it over with their healthcare provider first, since we don't have enough safety data.

California Poppy by Gaia Herbs: Common Questions

Does California Poppy by Gaia Herbs 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.
Can I take California poppy if I'm pregnant or breastfeeding?
There isn't enough safety data to know either way. The information we have advises against it during both pregnancy and breastfeeding. Talk with your doctor or pharmacist about what's right for you personally.
What side effects has California poppy caused?
We have limited information overall. When people used it in combination with hawthorn and magnesium, a few reported muscular stiffness, morning fatigue, and nausea—though we can't tell if California poppy itself caused those or if it was the blend.
Does California poppy actually help with sleep or anxiety?
The evidence isn't strong enough yet to say. We hold insufficient reliable evidence to rate it for either condition, so human studies haven't given us solid proof either way.
What's in this liquid besides the California poppy extract?
The inactive ingredients are alcohol and water. The alcohol helps extract and preserve the plant compound, so it's a key part of how the product works.
