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 Oct 8, 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.

Catnip Herbal Terra's single active ingredient is catnip flower and leaf extract, dry. Catnip is an herb whose extract is used in this liquid, and the active ingredient count is one.

The product also lists alcohol, water, and glycerin as inactive ingredients. These are not active ingredients and do not add to the herbal content.

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.

For each condition on the label's rating list, the evidence is rated Insufficient Reliable Evidence To Rate. This covers amenorrhea, anxiety, migraine headache, upper respiratory tract infection, dyspepsia, and flatulence.

In other words, reliable evidence is not established for any of these uses in the data we hold.

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 appropriate amounts, and our safety notes give it a caution for most adults in tea-sized amounts. Human safety data are limited, though.

Taking too much may cause headache, malaise, vomiting, or stomachache. In one reported case, a toddler who ate raisins soaked in catnip tea developed stomachache, irritability, and lethargy.

Our safety notes advise avoiding catnip during pregnancy, because it may stimulate the uterus and its safety has not been established. We do not hold a dedicated pregnancy or breastfeeding entry for this product, so breastfeeding safety is not on file.

Talk with your own doctor or pharmacist about your 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.

Double-check lithium and CNS depressants (sedating drugs) before taking this product, since both are rated Moderate in our data. We hold no interaction data for the ingredients we could not check.

Talk with your own doctor or pharmacist before combining catnip with any prescription.

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 suit adults who are curious about an herbal liquid and have no conflicting medications, though the evidence for its uses is not established. Anyone taking lithium or a sedating medication, anyone who is pregnant or breastfeeding, and parents of young children should be especially careful.

Talk it over with your own doctor or pharmacist before you start.
