HelloPharmacist Scorecard of California Poppy and Lavender 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.

From our pharmacy team — supplement deep dive

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 2 active ingredients.
  • “Proprietary Extract Blend” is a proprietary blend — the label gives one combined amount (983 mg) without saying how much of each component you get.

This product contains 2 active ingredients: California poppy extract and lavandin flower extract, delivered as a liquid blend. California poppy has been used traditionally for relaxation and sleep support.

The formula is completed with alcohol, water, and glycerin as inactive carrier ingredients.

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: Relaxation and sleep support.
  • We looked for evidence on: Anxiety, Insomnia, Nervous tension, 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.

The evidence we hold does not establish reliable ratings for California poppy's effectiveness for anxiety, insomnia, or nocturnal enuresis (bed-wetting). The data shows insufficient reliable evidence to rate it for any of these uses.

Lavandin flower extract effectiveness has not been rated in the data we hold.

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, though human safety data are limited. During pregnancy, safety data aren't sufficient — the facts advise against use.

The same applies to breastfeeding. The most commonly reported side effects from California poppy, when taken in combination with hawthorn and magnesium, include morning fatigue and nausea, though it's unclear whether these come from California poppy alone or the combination.

We hold no safety data for lavandin flower extract.

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 take this product, check whether you're on any central nervous system depressants — sedatives, sleeping pills, narcotic pain relievers, or anxiety medications — as California poppy may increase their drowsy effects (Moderate severity). Also note that this liquid contains alcohol, which can amplify sedation and interact with certain medications on its own.

Ask your pharmacist about your specific drugs.

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.

This product may help you relax if you're looking for a traditional herbal option, but the evidence for its effectiveness isn't established in our data. If you take any sedating medications or pain relievers, or if you're pregnant or breastfeeding, check with your pharmacist before starting.

California Poppy and Lavender by Herbal Terra: Common Questions

Does California Poppy and Lavender by Herbal Terra interact with any medications?

How can one product interact with so many drugs?

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.
Will this help me fall asleep?
California poppy has traditionally been used for sleep and relaxation, but we don't have reliable evidence that proves it works for insomnia. If you want to try it, talk with your pharmacist or doctor first, especially if you're on any sleep aids or medications that make you drowsy.
Can I take this if I'm pregnant or breastfeeding?
No — the safety data advises against use during pregnancy and while breastfeeding. There isn't enough information to know whether it's safe for you or your baby, so talk with your doctor or pharmacist about alternatives.
What are the side effects?
We have limited information about California poppy's side effects on its own. When it was used in combination with hawthorn and magnesium in some reports, people experienced morning fatigue and nausea, though it's unclear whether California poppy caused those or the other ingredients did.
Does this product contain any fillers?
The active ingredients are California poppy extract and lavandin flower extract. The product also contains alcohol, water, and glycerin as inactive carrier ingredients needed to make it a liquid.
What is lavandin flower extract?
Lavandin is a type of lavender used in this blend, traditionally for its calming properties. We don't hold effectiveness or safety data for this ingredient in our database, so we can't tell you what the evidence shows about it.
