HelloPharmacist Scorecard of Catnip by Nature's Answer

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 (Nepeta cataria) aerial parts extract — the leaves, stems, and flowers of the catnip plant in a concentrated liquid form. The extract is suspended in vegetable glycerin, purified water, and a small amount of certified organic alcohol.

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, digestion, and cold symptoms.
  • We looked for evidence on: Anxiety, Insomnia, Dyspepsia, Flatulence, Common cold, Upper respiratory tract infection (URTI) — and 2 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 isn't established yet. The data we hold rates it as having insufficient reliable evidence for amenorrhea (absent menstruation), anxiety, tension headaches, upper respiratory tract infections, indigestion (dyspepsia), and gas (flatulence).

That doesn't mean it doesn't work — it means large, well-designed human studies haven't confirmed it for these uses.

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 used in typical tea amounts, though human safety data are limited. The most common side effects reported are headache, malaise (that achy, unwell feeling), and vomiting.

Taking too much can cause stomachache and nausea. Catnip should be avoided during pregnancy because it may stimulate the uterus and safety isn't established.

Breastfeeding safety data aren't on file for this ingredient.

Side effects, ingredient by ingredient Catnip

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.

Check with your pharmacist before use if you take sedatives, sleep aids, anti-anxiety medications, or other drugs that depress the central nervous system — catnip may add to their drowsy effects. Also verify that you're not on lithium, which can accumulate to unsafe levels with catnip use.

Check your own medication Run your meds through the checker above

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 might appeal to someone looking for a traditional herbal remedy for relaxation, but the evidence for specific uses isn't solid yet. If you take sedatives, sleep aids, anti-anxiety medications, pain relievers with CNS effects, or lithium, you'll want to check with your pharmacist first.

Talk to us before starting — especially if you're pregnant or taking any prescription medications.

Catnip by Nature's Answer: Common Questions

Does Catnip by Nature's Answer 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.
What are the side effects of catnip?
Most people tolerate catnip well in normal amounts. The most commonly reported side effects are headache, malaise (that achy, unwell feeling), and vomiting. Taking large amounts may cause stomachache and nausea.
Is catnip safe during pregnancy?
No — catnip should be avoided during pregnancy. It may stimulate the uterus, and safety hasn't been established. Talk to your doctor or pharmacist if you're pregnant and considering any herbal remedy.
Can I take catnip with my sleep medication?
You'll need to check with your pharmacist first. Catnip has sedative properties and may add to the drowsy effects of sleep aids and other medications that slow down your nervous system, so your dose or choice of medication might need to change.
What is catnip actually used for?
Catnip has been used traditionally for anxiety, tension headaches, indigestion, gas, and other concerns. However, we don't have reliable evidence from large human studies that it works for these uses, so the evidence is rated insufficient.
Does this product contain any fillers or other inactive ingredients?
Yes — the liquid is made with vegetable glycerin, purified water, and a small amount of certified organic alcohol to preserve it. These are inactive ingredients that don't contribute to catnip's action.
