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.
What’s inside
Low disclosure
This product contains 2 active ingredients: certified organic California poppy (dried aerial parts extract) and certified organic hawthorn (dried leaves and flowers). Both are herbal extracts in a liquid form with menstruum as the inactive ingredient.
California poppy has a long history in herbal use for relaxation, while hawthorn is traditionally used to support heart and circulatory function.
Does it work?
Couldn't assess
The evidence for both ingredients in this product is not yet established in reliable human trials. California poppy's effectiveness for anxiety, insomnia, and bedwetting (nocturnal enuresis) is rated as having insufficient reliable evidence to rate.
Similarly, hawthorn's effectiveness for angina, anxiety, heart rhythm issues, atherosclerosis, cardiovascular disease, and cognitive function all carry the same insufficient-evidence rating. If you're considering this product for a specific health concern, talk with your doctor or pharmacist about whether the current evidence supports its use for your situation.
How safe is it?
Well-documented data
California poppy is generally considered mild for short-term use, though human safety data are limited. The most commonly reported effects when used together with hawthorn and magnesium include muscular stiffness, morning fatigue, and nausea — though it's unclear whether these come from California poppy alone, hawthorn, the combination, or the other ingredients.
Hawthorn is generally well tolerated in studies, but because it affects heart function and blood pressure, anyone with a heart condition should only use it under medical supervision. Rare serious reactions (like acute kidney failure from allergic-type reactions) and occasional reports of palpitations or heart rhythm changes have been documented, mostly in people with existing heart disease.
Meds to double-check
Major interaction found
Before taking this product, double-check it with your doctor or pharmacist if you take nitrates, phosphodiesterase-5 inhibitors (like sildenafil/Viagra), beta-blockers, blood thinners, calcium channel blockers, digoxin, or any CNS depressants (like benzodiazepines or opioids). These interactions range from Major to Moderate severity and can affect blood pressure, heart function, bleeding risk, or sedation.
The bottom line
Scorecard at a glanceFormula with limited ingredient disclosure with no assessable stated purpose. Major medication interactions have been identified, and safety information is well characterized.
This product combines two herbs with a long history in traditional use but limited evidence in human trials for the conditions they're marketed for. If you take any heart medications, blood pressure drugs, blood thinners, or sedating medications, you need to check with your doctor or pharmacist before starting it — the interactions are real and can be serious.
Even without those medications, anyone with a heart condition should discuss it with their healthcare provider first.

California Poppy and Lavender by Herbal Terra Drug Interactions
HelloPharmacist Interaction Report
Herbal Terra's California Poppy and Lavender contains two active ingredients with documented interactions.
The most serious concerns involve hawthorn, which carries Major-severity interactions with nitrates (used for chest pain) and phosphodiesterase-5 inhibitors like sildenafil (Viagra). Both can cause dangerous drops in blood pressure when combined with hawthorn due to additive blood vessel–relaxing effects.
Read the full breakdown — every affected drug type, severity by severity
Hawthorn also has Moderate-severity interactions with beta-blockers, blood thinners (anticoagulants and antiplatelet drugs), calcium channel blockers, and digoxin (a heart medication). These can amplify effects on blood pressure, heart rate, bleeding risk, or heart function.
California poppy carries a Moderate-severity interaction with CNS depressants — drugs like benzodiazepines or opioids that slow the central nervous system — because combining them may increase sedation beyond what either alone would cause.
Altogether, these interactions span 420 individual medications. Before taking this product, check your exact medications with the search tool on this page or talk with your doctor or pharmacist, especially if you have heart disease, take heart or blood pressure medications, or use any sedating drugs.

certified organic California Poppy (Eschscholzia californica) dried aerial parts extract
Cns Depressants
Theoretically, taking California poppy with drugs with sedative effects may increase the risk of sedative effects.
Laboratory research shows that California poppy has sedative effects.
certified organic Hawthorn (Crataegus laevigata) dried leaves and flowers
Nitrates
Theoretically, concomitant use might cause additive coronary vasodilatory effects.
Some evidence shows that hawthorn might lower blood pressure due to vasodilatory effects.
Phosphodiesterase-5 Inhibitors
Theoretically, concomitant use might result in additive vasodilation and hypotension.
Hawthorn might inhibit PDE-5 and cause vasodilation.
Anticoagulant/Antiplatelet Drugs
Theoretically, hawthorn may increase the risk of bleeding if used with anticoagulant or antiplatelet drugs.
In vitro and animal research shows that hawthorn can inhibit platelet aggregation. However, its effect in humans is unclear. One observational study shows that patients taking hawthorn shortly before undergoing coronary artery bypass graft (CABG) surgery or valve replacement surgery have a 10% incidence of postoperative bleeding, compared with 1% in those who never consumed hawthorn extract. However, clinical research shows that taking a specific preparation of dried hawthorn leaves and flowers (Crataesor, Soria Natural Lab) 800 mg three times daily for 15 days does not affect platelet aggregation or levels of thromboxane B2, the metabolite of thromboxane A2, in healthy humans.
Beta-Blockers
Theoretically, concomitant use might cause additive effects on blood pressure and heart rate.
Some evidence shows that hawthorn might lower blood pressure and heart rate.
Calcium Channel Blockers
Theoretically, concomitant use might cause additive coronary vasodilation and hypotensive effects.
Some evidence shows that hawthorn might lower blood pressure due to vasodilatory effects.
Digoxin (Lanoxin)
Theoretically, hawthorn might potentiate the effects and adverse effects of digoxin.
Hawthorn appears to improve cardiac output; however, hawthorn does not appear to affect digoxin pharmacokinetics. Case reports suggest that at least one species of hawthorn root extract (Crataegus mexicana) may produce adverse effects similar to digoxin and can cross-react with digoxin assays, leading to falsely elevated plasma digoxin levels.
