HelloPharmacist Scorecard of Catnip by Hawaii Pharm

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: catnip leaf and flower extract in dried form. The liquid also includes alcohol, water, and glycerin as inactive ingredients to deliver the herb.

Does it work?

Insufficient 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
Insufficient

There isn't enough reliable clinical evidence to rate this product's ingredients for its stated purpose.

Why this rating?
  • The label markets this product for: Sleep, anxiety, and digestive support.
  • We looked for evidence on: Anxiety, Insomnia, Dyspepsia, Flatulence, Common cold, Upper respiratory tract infection (URTI) — and 4 related terms.
  • The closest evidence on file: Catnip is rated "Insufficient Reliable Evidence To Rate" for Anxiety (Natural Medicines).
  • Also on file: Catnip is rated "Insufficient Reliable Evidence To Rate" for Upper respiratory tract infection (URTI), Dyspepsia, Flatulence, Insomnia, and more.

The evidence for catnip is limited. For amenorrhea (absent periods), anxiety, tension headache, upper respiratory tract infection, indigestion, and gas, we don't have enough reliable data to say whether it works.

If you're thinking of using it for one of these conditions, talk with your pharmacist or doctor about what the research actually supports.

The evidence, ingredient by ingredient Catnip

How safe is it?

Some data gaps
Safety Information · database check
Some gaps

Safety data exists for these ingredients, but with some important gaps.

Why this rating?
  • We hold adverse-effect (side-effect) data for 1 of the 1 matched ingredient.
  • Pregnancy & breastfeeding safety ratings cover 0 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.

Catnip is generally well tolerated when taken by mouth in typical tea-like amounts, though human safety data are sparse. The most common side effects reported are headache, malaise (general discomfort), and vomiting.

Taking too much can cause stomach upset and vomiting; in one case, a toddler who ingested a large amount developed stomach upset, irritability, then lethargy and a sedated state. Catnip is not recommended during pregnancy, as it may stimulate the uterus and safety hasn't been established.

We have no data on whether it's safe while breastfeeding — talk with your doctor or pharmacist for personalized advice.

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 — Catnip.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: lithium.
  • For scale: 248 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 taking this product, check with your pharmacist if you take any CNS depressants (sleep aids, opioid painkillers, anti-anxiety drugs, or sedating allergy medicines) or lithium. Catnip may boost their effects or change how lithium works in your body.

The bottom line

Scorecard at a glanceFully disclosed formula with insufficient evidence for its stated purpose. Moderate medication interactions have been identified, and some safety-information gaps remain.

Catnip may be an option if you're interested in herbal approaches, but evidence for its effectiveness is thin across most uses. If you take CNS depressants or lithium, check with us first.

Pregnant people should avoid it. Talk to your pharmacist before you start.

Catnip by Hawaii Pharm: Common Questions

Does Catnip by Hawaii Pharm interact with any medications?
Yes. Based on its ingredients, Catnip has a known interaction with 248 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Catnip 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.
Can I take this if I'm pregnant?
No. Catnip may stimulate the uterus, and safety in pregnancy hasn't been established. Avoid it during pregnancy and talk with your doctor or pharmacist.
What are the most common side effects?
Headache, general discomfort (malaise), and vomiting are the most commonly reported. Most people tolerate it well in standard amounts, but human safety data are limited.
Does catnip actually work for anxiety or sleep?
We don't have enough reliable evidence to say whether catnip works for anxiety. For sleep or other uses listed, the evidence is also insufficient. It's not proven to help with these conditions.
What happens if I take too much?
Large amounts can cause stomach upset, vomiting, headache, and malaise. In rare cases (like a toddler drinking a lot of catnip tea), it can cause drowsiness or a sedated state. Stick to normal doses.
Is it safe while breastfeeding?
We don't have enough safety data to know either way. Talk with your doctor or pharmacist before using catnip if you're breastfeeding.
Why does the label say 'Likely fine for most adults in tea amounts, but human safety data are limited'?
Catnip has a long history of use in teas, and people generally tolerate it well. However, we don't have a lot of modern scientific study on safety — so we're being honest about what we know and don't know.
