HelloPharmacist Scorecard of Catnip Herb by Nature's Way

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.

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.

Nature's Way Catnip Herb is a single-ingredient capsule containing organic catnip. The capsule itself is made with gelatin (an inactive ingredient that holds the herb powder).

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's effectiveness isn't established in the data we hold. The product is traditionally used for conditions like anxiety, tension headaches, indigestion, bloating, and upper respiratory infections, but the research doesn't support these uses strongly enough to rate them as proven.

If you're considering catnip for a specific health goal, talk with your doctor or pharmacist about whether the evidence supports it.

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 in typical amounts, though human safety data are limited. The most common side effects reported are headache, general malaise (feeling unwell), and vomiting — and large amounts may cause stomachache.

There's one case of a toddler who became sleepy and irritable after ingesting catnip-soaked raisins. Catnip should be avoided during pregnancy, as it may stimulate the uterus and its safety in pregnancy is not established.

Not enough safety information is available for other populations, so talk with your doctor or pharmacist before taking it if you have questions about your individual situation.

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 before taking this if you use lithium — catnip may increase lithium levels and your dose might need adjustment. Also check if you take any CNS depressants (sedatives, sleep aids, antidepressants, anxiety medications, or strong pain relievers), because catnip can add to their drowsy effects.

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.

Catnip may appeal to you if you're interested in herbal traditions, but the evidence for what it actually does is sparse. The main medication concerns are lithium and sedating drugs — both need your doctor or pharmacist's sign-off.

If you take any prescription medications, check them against this page before starting, and have that conversation with your own healthcare provider.
