HelloPharmacist Scorecard of Passion Flower by Paradise

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

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.

Paradise Passion Flower is a single-ingredient supplement: passion flower aerial parts extract in a capsule. The capsule itself is an inactive ingredient — just the container holding the active extract.

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

This product doesn't appear to be marketed for a specific use, so we graded Passion Flower's overall clinical evidence instead.

Moderate

Some clinical evidence supports Passion Flower for:

Why this rating?
  • We looked at the product name, claims, and label statements and couldn't find a stated purpose to grade.
  • Since the label doesn't commit to one use, we graded the ingredient's overall clinical evidence instead.
  • On file: Pre-procedural anxiety — rated "Possibly Effective" (Natural Medicines).
  • On file: Insomnia — rated "Possibly Effective" (Natural Medicines).

The data we hold shows passion flower is possibly effective for insomnia and for easing anxiety before medical procedures. For attention deficit-hyperactivity disorder (ADHD) and benzodiazepine withdrawal, there isn't enough reliable evidence yet to say whether it works.

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 over the short term, but drowsiness is the main side effect to watch for — you may also feel confused or dizzy. The safety data advises against using it during pregnancy because we don't know enough about its safety, and it may affect the uterus.

There isn't enough information to recommend it while breastfeeding either. Rarely, people have reported allergy symptoms like sinus irritation, and one case involved severe nausea, vomiting, and heart rhythm changes at very high doses — all resolved when the supplement was stopped.

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.

Before you take Paradise Passion Flower, check with your doctor or pharmacist if you're on any CNS depressants (sedatives, sleep aids, tranquilizers, or anti-anxiety drugs) — passion flower can boost their drowsy effects. Also flag any drugs that use the OATP or CYP3A4 pathways in your liver; passion flower may slightly lower their effectiveness.

Passion Flower Aerial Parts Extract3 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.
