HelloPharmacist Scorecard of Passion Flower Extract by Herbadiet

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

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: Passionflower Whole Plant Extract, Powder. There are no inactive ingredients listed.

Does it work?

Moderate evidence
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
Moderate

Some clinical evidence supports this product's ingredients for its stated purpose, but it isn't conclusive.

Why this rating?
  • The label markets this product for: Natural stress relief.
  • We looked for evidence on: Stress, Pre-procedural anxiety, Adjustment disorders, Insomnia, Anxiety, Restlessness — and 1 related terms.
  • The strongest evidence on file: Passion Flower is rated "Possibly Effective" for Pre-procedural anxiety (Natural Medicines).
  • Also on file: Passion Flower is rated "Possibly Effective" for Insomnia.
  • Also on file: Passion Flower is rated "Insufficient Reliable Evidence To Rate" for Adjustment disorders, Stress.

Passion flower is rated Possibly Effective for insomnia and pre-procedural anxiety (the jitters before a medical procedure). For alcohol use disorder and benzodiazepine (a type of sedative) withdrawal, the evidence isn't strong enough to rate — we don't have reliable data yet on whether it helps with those.

The evidence, ingredient by ingredient Passion Flower

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.

Passion flower is generally well tolerated in the short term, but drowsiness is the most common side effect you might notice, along with dizziness and confusion in some people. A small number of trial participants reported allergy-like symptoms including sinus irritation.

There's also one case report of severe nausea, vomiting, and heart rhythm changes at very high doses (1500–2000 mg), though symptoms resolved within a week after stopping. Don't use this product during pregnancy — there isn't enough safety data, and it may affect the uterus.

There also isn't enough information to recommend it while breastfeeding; talk with your doctor or pharmacist for personalized advice.

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 — Passion Flower.
  • The most serious interaction on file is rated Moderate.
  • For scale: 837 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 your exact medications against these drug types: CNS depressants (Moderate severity) — sedatives, sleep aids, anti-anxiety drugs — can have additive drowsy effects with passion flower. Also check if you take drugs that use OATP2B1/OATP1A2 transporters or depend on CYP3A4 for breakdown, as passion flower may reduce their blood levels (Minor severity).

Check your own medication Run your meds through the checker above

The bottom line

Scorecard at a glanceFully disclosed formula with some supporting evidence for its stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

Passion flower is an option if you're looking for help with sleep or pre-procedure anxiety and want a plant-based choice. Just watch for drowsiness, and avoid it if you're already on sedatives without checking first.

Pregnant or breastfeeding? Skip it and talk to your doctor.

Always run your medications through the checker before you start.

Passionflower Whole Plant Extract, Powder3 drug types · 836 drugs

Cns Depressants

Concomitant use of passion flower with sedative drugs might cause additive effects and side effects.
Research in animals and humans shows that passion flower has sedative effects which can be additive when used with sedative medications like lorazepam.

Likelihood Possible Evidence D
Cytochrome P450 3A4 (Cyp3A4) Substrates

Theoretically, passion flower might decrease the effects of CYP3A4 substrates.
In vitro research suggests that passion flower can induce CYP3A4 enzymes, albeit to a much lower degree than rifampin, a known CYP3A4 inducer.

Likelihood Possible Evidence D
Organic Anion-Transporting Polypeptide Substrates (Oatp)

Theoretically, passion flower might reduce the bioavailability of OATP2B1 and OATP1A2 substrates.
In vitro research shows that the passion flower constituents apigenin and vitexin inhibit OATP2B1 and OATP1A2. This inhibition may be dose-dependent. One specific high-flavonoid passion flower extract (Valverde) seems to inhibit OATP2B1 and OATP1A2, while another extract with a lower flavonoid concentration (Arkocaps) shows less potent inhibition. OATPs are responsible for the uptake of drugs and other compounds into the body; however, the specific activities of OATP2B1 and OATP1A2 are not well characterized.

Passion Flower Extract by Herbadiet: Common Questions

Does Passion Flower Extract by Herbadiet interact with any medications?
Yes. Based on its ingredients, Passion Flower Extract has a known interaction with 836 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Passion Flower Extract 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.
Will this make me drowsy?
Yes, drowsiness is the most common side effect. That's actually part of how it works for sleep and anxiety — but it means you shouldn't drive or use heavy machinery after taking it, and you definitely shouldn't combine it with other sedating drugs without talking to your pharmacist first.
Can I take this while pregnant?
No. The safety data isn't there, and passion flower may have effects on the uterus. Skip it and talk with your doctor about what's safe for you during pregnancy.
Can I breastfeed if I take passion flower?
There isn't enough safety information to say it's okay. Talk with your doctor or pharmacist — they can help you weigh the pros and cons for your situation.
Does this really help with insomnia?
The evidence says it's Possibly Effective for insomnia. That means some research supports it, but we don't have bulletproof proof yet. It's worth trying if you want to, but it's not a guarantee.
What if I'm allergic to plants?
A small number of people in trials reported allergy-like symptoms, including sinus irritation. There's also one case of an unusual allergic reaction with hives and skin inflammation, though it's unclear whether passion flower or another ingredient was responsible. If you have plant allergies, be cautious and watch for symptoms.
Is there anything else in this powder besides passion flower?
No — it's just the passionflower extract. No fillers or other inactive ingredients are listed.
