HelloPharmacist Scorecard of Wild Lettuce and 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.

From our pharmacy team — supplement deep dive

Generated from HelloPharmacist’s pharmacist-curated databases and editorial rules · Last generated Jul 11, 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 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 liquid product contains 2 active herbal ingredients: California poppy extract and wild lettuce herb extract (dried form). Both are traditional botanicals used for their calming properties.

The product also contains alcohol, water, and glycerin as inactive ingredients to preserve and deliver the extracts.

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

The label doesn't state a purpose we can grade — see each ingredient's own graded uses on its monograph instead.

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 both ingredients is limited. California poppy has been used traditionally for anxiety and sleep problems, but the scientific data we hold rates both as having insufficient reliable evidence to support those uses.

Wild lettuce has no effectiveness ratings on file. If you're considering this for a specific concern like anxiety or insomnia, that's a good conversation to have with your pharmacist or doctor about what the research actually shows.

The evidence, ingredient by ingredient California Poppy Wild Lettuce

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 2 of the 2 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 2 of 2.
  • General safety write-ups exist for 2 of 2.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Both herbal extracts have limited human safety data, especially with long-term use. California poppy is considered generally mild for short-term use.

When wild lettuce is taken in large amounts or harvested too early, it can cause serious effects including dizziness, nausea, sweating, increased heart rate, and rarely respiratory depression or coma—so this is not a "more is better" supplement. Small numbers of people using California poppy in combination with hawthorn and magnesium reported morning fatigue, muscular stiffness, and nausea, though it's unclear whether those came from the poppy or the other ingredients.

The product is not recommended during pregnancy or while breastfeeding due to insufficient safety data.

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?
  • 2 of the 2 matched ingredients can interact with medications — California Poppy, Wild Lettuce.
  • The most serious interaction on file is rated Moderate.
  • For scale: 393 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 with your pharmacist before taking this if you use any sedating medications (like sleep aids, anti-anxiety drugs, prescription pain relievers, or cold medicines with sedating effects) or anticholinergic medications (for overactive bladder, muscle spasms, or Parkinson's disease). Both active ingredients in this product can interact with these drug types.

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.

This product is for people interested in herbal calming support, but it's not for anyone on sedating medications without a pharmacist's okay first. Pregnant or breastfeeding?

Skip it—not enough safety data. Talk to us about your medications and any health conditions before you start.

Anticholinergic Drugs

Studies report varying evidence on whether or not wild lettuce contains hyoscyamine, an anticholinergic drug. If it does, it appears to be in very low amounts. Nevertheless, there have been case reports of individuals consuming large amounts of wild lettuce experiencing anticholinergic-related side effects, such as constipation, dry mouth, dizziness, and sweating. Therefore, if you are already taking a drug with anticholinergic effects, you should be cautious about combining it with wild lettuce as the risk of side effects may be increased.

Wild Lettuce and California Poppy by Herbal Terra: Common Questions

Does Wild Lettuce and California Poppy by Herbal Terra interact with any medications?
Yes. Based on its ingredients, Wild Lettuce and California Poppy has a known interaction with 393 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Wild Lettuce and California Poppy contains 2 active ingredients, and an interaction can come from any of them. We check every ingredient, combine the results into one list per medication, and show which ingredient and mechanism is 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 this if I'm on a prescription sleep aid?
Not without checking first. Both California poppy and wild lettuce can add to the drowsiness and sedative effects of sleep medications. Talk to your pharmacist or doctor before combining them—the mix could make you too drowsy or impair your thinking.
Is it safe during pregnancy or breastfeeding?
No. There isn't enough safety data for either ingredient during pregnancy or breastfeeding, so the guidance is to avoid it. Talk with your OB or midwife if you're looking for calming support during that time.
What side effects should I watch for?
Information on side effects is limited, but wild lettuce in large amounts has caused dizziness, nausea, sweating, and increased heart rate. When California poppy was used with other herbs (hawthorn and magnesium), some people reported morning fatigue, stiffness, and nausea—though it's unclear which ingredient caused it. Stick to the label dose.
Does this actually work for anxiety or sleep?
The scientific evidence is insufficient to say for sure. California poppy is used traditionally for both, but reliable human studies backing those uses aren't on file. If you need help with anxiety or insomnia, that's worth discussing with your doctor too.
What are California poppy and wild lettuce?
Both are herbal plants used traditionally for their calming and sedative properties. California poppy is a flower native to the western US; wild lettuce is a plant that's been used in herbal medicine for centuries. The product contains concentrated extracts of each.
