HelloPharmacist Scorecard of Catnip by Nature's Sunshine

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

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. The capsule itself is an inactive ingredient used to deliver the catnip powder.

Does it work?

Not established
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
Not established

The graded evidence we hold for these ingredients covers different conditions than the ones this product is marketed for, so there's no established rating for its stated use — see Catnip's own graded uses on its monograph.

Why this rating?
  • The label markets this product for: calming support and nervous system support.
  • We looked for evidence on: Anxiety, Insomnia, stress, nervous tension.
  • 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 Insomnia.

The evidence for catnip's effectiveness isn't established in the data we hold. We have insufficient reliable evidence to rate it for amenorrhea, anxiety, tension headaches, upper respiratory tract infections, indigestion, or gas.

If you're considering catnip for any of these, talk with your doctor about whether the evidence supports it for your situation.

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 amounts, though human safety data are limited. The most common side effects reported are headache, malaise, and vomiting.

Taking too much may also cause stomachache. Catnip is not recommended during pregnancy, as it may stimulate the uterus and its safety in pregnancy is not established.

There isn't enough safety information available for other situations either, so discuss this with your doctor or pharmacist if you're pregnant, breastfeeding, or have specific health concerns.

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 taking catnip, check with your doctor or pharmacist if you take CNS depressants (drugs that cause drowsiness or sedation, including sleep aids and anti-anxiety medications) or lithium. Catnip may amplify drowsiness with the first group and could alter lithium levels with the second.

The bottom line

Scorecard at a glanceFully disclosed formula with no established evidence rating for its marketed use. Moderate medication interactions have been identified, and some safety-information gaps remain.

Catnip may appeal to you if you're exploring herbal options for anxiety or sleep, but the evidence supporting those uses isn't solid yet. If you take CNS depressants (like sleeping pills or anti-anxiety drugs) or lithium, check with your doctor or pharmacist first—the interactions are real and could affect how those medications work.

A conversation with your own healthcare provider will help you decide if this is the right choice for you.

Catnip by Nature's Sunshine: Common Questions

Does Catnip by Nature's Sunshine 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.
Will catnip make me drowsy?
Catnip does have sedative properties, so it may cause drowsiness, especially if you take it in larger amounts. If you experience headache, malaise, or vomiting, you're taking too much—scale back the dose.
Is catnip safe during pregnancy?
No, catnip is not recommended during pregnancy. It may stimulate the uterus, and its safety in pregnancy hasn't been established. Talk with your doctor if you're pregnant or planning to become pregnant.
Can I take catnip with my sleeping pills?
Not without checking first. Catnip has sedative properties that could add to the drowsiness your sleeping pills already cause, which could be unsafe. Discuss this with your doctor or pharmacist before combining them.
Does catnip actually work for anxiety or sleep?
The evidence isn't strong enough to rate. We don't have reliable data showing catnip works for anxiety, sleep, tension headaches, or any of the other uses people try it for, so the data can't tell you whether it will help your situation.
What's in each capsule?
Each capsule contains catnip powder and the capsule shell itself as an inactive ingredient.
