HelloPharmacist Scorecard of Catnip by Herbal Terra

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: a liquid extract of certified organic catnip (Nepeta cataria) made from the dried leaf and flower. The extract is suspended in menstruum, which is the liquid used to draw out catnip's compounds.

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 support.
  • We looked for evidence on: Anxiety, Insomnia, Dyspepsia, Flatulence, Common cold, Upper respiratory tract infection (URTI) — and 3 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 in our data. We hold insufficient reliable evidence to rate it for the conditions it's traditionally used for — amenorrhea (missing periods), anxiety, tension headaches, upper respiratory infections, indigestion, and bloating.

That doesn't mean it doesn't work; it means larger or better-designed human trials haven't yet been done.

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 you use it in reasonable amounts — headache, nausea, and vomiting are the most common side effects reported, though they're not frequent. Human safety data are limited overall.

The safety data advises against use during pregnancy, as catnip may stimulate the uterus and safety hasn't been established. There isn't enough information to know whether it's safe during breastfeeding, so talk with your doctor or pharmacist for personalized advice if that applies to you.

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.

Before starting this product, check whether you take lithium or any CNS depressants — sedatives, sleep aids, anti-anxiety medications, and opioid painkillers. Both interactions are Moderate severity and may affect how your medications work or how you feel.

Your pharmacist can search your exact medications against the full list.

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 worth trying if you're looking for a traditional remedy for anxiety or digestive upset and you don't take lithium or sedating medications. If you do take either of those drug types, check with your pharmacist first — a dose adjustment might be needed.

Steer clear during pregnancy. Because human safety data are limited, it's a good idea to start with small amounts and see how you feel.

Catnip by Herbal Terra: Common Questions

Does Catnip by Herbal Terra 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 while I'm pregnant?
No — the safety data advises against it. Catnip may stimulate the uterus, and safety in pregnancy hasn't been established. Talk with your doctor before taking it if you're pregnant or trying to become pregnant.
What are the side effects?
Catnip is generally well tolerated at normal doses. The most common side effects reported are headache, nausea, and vomiting, though they're not frequent. Taking too much might cause stomach upset and vomiting.
Does catnip actually work for anxiety or upset stomach?
The evidence isn't strong enough yet. We hold insufficient reliable evidence to rate catnip for anxiety, indigestion, bloating, or the other conditions it's traditionally used for. That doesn't prove it doesn't work — it just means we need bigger, better-designed studies.
What exactly is in this liquid extract?
It's catnip leaf and flower extract suspended in menstruum — the liquid used to draw out catnip's active compounds. There's one active ingredient, and menstruum is just the carrier.
Is it safe to breastfeed while taking this?
There isn't enough data to know either way. Talk with your doctor or pharmacist for personalized advice if you're breastfeeding or planning to.
