HelloPharmacist Scorecard of Full Spectrum Catnip 400 mg by Swanson Premium Brand

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 30, 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 (400 mg per capsule). The capsule also includes gelatin and rice flour as inactive ingredients (fillers and binders); the label notes it may contain additional inactive ingredients.

Does it work?

Couldn't assess
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 assessable

This is a single-ingredient Catnip product and its label doesn't state a use — see Catnip's own graded uses on its monograph.

Why this rating?
  • We looked at the product name, claims, and label statements and couldn't find a stated purpose to grade.

The evidence for catnip is insufficient to rate its effectiveness for the conditions listed on the label — amenorrhea (missing periods), anxiety, tension headaches, common cold, indigestion (dyspepsia), and gas (flatulence). We don't have reliable data showing it works for any of these uses.

If you're considering it for one of these purposes, talk it over with your doctor or pharmacist to see if there are better-studied options.

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 appropriate amounts, though human safety data are limited. The most common side effects reported are headache, malaise (a general feeling of illness), and vomiting.

Large amounts may cause stomach upset and vomiting. Because catnip may stimulate the uterus and safety in pregnancy is not established, it should be avoided during pregnancy.

Safety information for breastfeeding is not on file.

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 you take this, double-check any CNS depressants (sleep aids, anti-anxiety drugs, pain relievers with sedative effects) and lithium with your doctor or pharmacist. Both carry Moderate interaction risk with catnip.

Check your own medication Run your meds through the checker above

The bottom line

Scorecard at a glanceFully disclosed formula with no assessable stated purpose. Moderate medication interactions have been identified, and some safety-information gaps remain.

This product is a single-ingredient catnip supplement with limited evidence for any health benefit and documented interactions with sedating medications and lithium. If you take any CNS depressants or lithium, or if you're pregnant, check with your doctor or pharmacist before using it.

For most others, the main concern is whether it'll actually do what you're hoping it will — and the data don't yet show that.

Does Full Spectrum Catnip 400 mg by Swanson Premium Brand interact with any medications?
Yes. Based on its ingredients, Full Spectrum Catnip 400 mg 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?
Full Spectrum Catnip 400 mg 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 pregnant?
No — catnip should be avoided during pregnancy because it may stimulate the uterus and its safety in pregnancy is not established. If you're pregnant or planning to become pregnant, talk with your doctor or pharmacist before using any catnip product.
What are the side effects?
Catnip is generally well tolerated in appropriate amounts. The most common side effects are headache, a general feeling of illness (malaise), and vomiting. Taking too much may cause stomach upset, headache, and malaise.
Does catnip really work for anxiety or headaches?
We don't have reliable evidence yet. Catnip has insufficient evidence to rate it for anxiety, tension headaches, or any of the other uses listed on this label. If you're looking to treat one of these conditions, your doctor or pharmacist can suggest options with stronger evidence behind them.
Is this safe to take every day?
Human safety data for catnip are limited, so we don't have solid information on long-term daily use. Talk with your doctor or pharmacist about whether daily use is right for you.
What's in the capsule besides catnip?
The capsule contains gelatin (the capsule material itself) and rice flour as inactive ingredients. The label notes it may contain additional inactive ingredients as well.
