HelloPharmacist Scorecard of California Poppy by Herbs Etc.

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: fresh California Poppy, a plant traditionally used for relaxation. It's delivered as a liquid, mixed with grain alcohol and purified water as inactive ingredients.

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 in the data we hold. For anxiety, insomnia, and nighttime bedwetting, the ratings are all insufficient reliable evidence—meaning there's not enough solid research to say whether it works for these uses or not.

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 when used short-term, but human safety data are limited. The few side effects reported come from a combination product also containing hawthorn and magnesium—muscular stiffness, morning fatigue, and nausea—and it's unclear whether California poppy itself was responsible.

There isn't enough safety data for pregnancy or breastfeeding; the safety data advises against use in both situations. Talk with your doctor or pharmacist if you're pregnant, planning pregnancy, or nursing before taking this product.

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.

Check any medications that slow your central nervous system before taking this product—sedatives, sleeping pills, anxiety medications, and pain relievers with sedative effects are the main ones to watch. This is a moderate-severity interaction, so confirmation from your own doctor or pharmacist matters.

The bottom line

Scorecard at a glanceFormula with limited ingredient disclosure with no assessable stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

California Poppy might appeal to you if you're looking for a mild herbal approach to relaxation, but the evidence for its effectiveness isn't established. The main caution is with sedating medications—combining them could amplify drowsiness.

Before you start, check with your own doctor or pharmacist about your specific medications and situation.
