HelloPharmacist Scorecard of Passion Flower Glycerite by Eclectic Herb

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 Sep 3, 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 1 active ingredient.

Passion Flower Glycerite contains one active ingredient: passionflower (dry form). A glycerite is simply passionflower extract preserved in glycerin instead of alcohol, which doesn't change how the herb works in your body.

This product has no other inactive ingredients on file.

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).

Passionflower is possibly effective for insomnia and for easing anxiety before medical procedures — meaning there's decent research backing it, though it's not a slam-dunk. For ADHD and benzodiazepine withdrawal, we don't have 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.

Passionflower is generally well tolerated when used short-term, but drowsiness is common — so don't drive or operate machinery right after taking it. The most frequent side effects in trials were confusion, dizziness, and sedation.

Rarely, people have reported allergy symptoms like sinus irritation, and there's one case report of severe nausea, vomiting, and heart rhythm changes at very high doses, though all resolved after stopping. Don't use this during pregnancy — there isn't enough safety data, and passionflower may affect the uterus.

Breastfeeding is also best avoided because we don't have enough information to say it's safe for your baby.

Side effects, ingredient by ingredient Passion Flower

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 — 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 before taking this product if you're on sedative or anti-anxiety medications, sleep aids, or any painkiller with sedative effects — passionflower can boost their drowsiness. Also mention any drugs that depend on OATP transporters or CYP3A4 processing if you know them, though your pharmacist can look those up for you.

The bottom line

Scorecard at a glanceFormula with limited ingredient disclosure with some supporting evidence behind its ingredients' uses. Moderate medication interactions have been identified, and safety information is well characterized.

Passion Flower Glycerite might help if you're struggling with sleep or pre-procedure jitters, and it's generally well tolerated short-term. The main caution is mixing it with sedatives or anti-anxiety medications — they can strengthen each other's drowsy effects.

Talk with your doctor or pharmacist before starting, especially if you take any prescriptions, are pregnant, or are nursing.

Passionflower, Dry3 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 Glycerite by Eclectic Herb: Common Questions

Does Passion Flower Glycerite by Eclectic Herb interact with any medications?
Yes. Based on its ingredients, Passion Flower Glycerite 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 Glycerite 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 one of the most common side effects. It's actually why passionflower can help with sleep, but you shouldn't drive or use machinery right after taking it. If you're sensitive to sedating herbs, start with a small dose and see how you feel.
Can I take this if I'm pregnant?
No, the safety data advises against it during pregnancy because we don't know enough about how it affects you and your baby, and it may have effects on the uterus. Talk with your doctor about other options for sleep or anxiety during pregnancy.
Is it safe while breastfeeding?
There isn't enough safety information to recommend it while breastfeeding. Check with your doctor or pharmacist about whether this is okay for you and your baby before using it.
Can I take this with my sleep medication?
Probably not without checking first. Passionflower can add to the drowsy effects of sedatives and sleep aids, which could make you too impaired. Your doctor or pharmacist can tell you if the combination is safe at a certain dose, or if you should pick one or the other.
Does this actually work for insomnia?
The evidence says it's possibly effective — meaning there's research suggesting it can help, but it's not guaranteed. Some people sleep better on it; others don't notice much. Give it a fair trial and see if it works for you.
