Plant
Catnip
Nepeta cataria
Also known as: Nepeta cataria, catmint, catswort
A perennial herb in the mint family (Lamiaceae), native to Europe, central Asia, and parts of China — now naturalized across temperate North America, Australia, and many other introduced ranges. The plant produces nepetalactone, a volatile terpenoid that triggers a stereotyped behavioral response in domestic cats and many other felids (lions, tigers, leopards, bobcats, lynxes all respond) — rolling, rubbing, salivating, kneading, and apparent euphoria for 5–15 minutes. About 70–80% of cats show the response; the trait is inherited as an autosomal dominant. Catnip is also a traditional human herbal tea for relaxation, mild sedation, and digestive complaints — humans don't experience anything like the feline response.
Scientific
Nepeta cataria (family Lamiaceae — same family as [[mint]], [[basil]], [[oregano]], etc.) produces the volatile terpenoid nepetalactone, which is the active compound responsible for the feline behavioral response.
Cats encounter nepetalactone through smell — the compound binds receptors in the cat’s vomeronasal organ (the secondary olfactory system most mammals have for pheromone detection). The response then propagates through the cat’s amygdala and other emotion-processing regions, producing the stereotyped 5–15 minute behavioral display: rolling, rubbing, salivating, kneading, vocalizing, jumping, and (for indoor cats especially) seeking out and consuming the plant material.
About 70–80% of domestic cats show a strong response; the remaining 20–30% are unaffected. The trait is inherited (autosomal dominant), so non-responsive cats genuinely lack the receptor variants needed to detect or respond to the compound. The pattern is consistent across most felids — lions, tigers, leopards, jaguars, snow leopards, lynx, and bobcats all respond similarly (which is one of the more entertaining footnotes of comparative felid biology).
Human medicinal use
For humans, catnip is essentially the opposite of stimulating — it’s a traditional mild-sedative herb. The plant has been used in European folk medicine for centuries:
- Catnip tea for relaxation, mild insomnia, and anxiety
- Catnip preparations for digestive complaints, gas, and indigestion
- Topical catnip oil for headaches
The species was historically a far more popular human medicinal tea than it is today — the modern association of catnip with cats has overshadowed the centuries-old human use. The compound nepetalactone also has mosquito-repellent properties (some research suggests it’s more effective than DEET for some mosquito species).
Cultural and economic
Catnip is widely cultivated as a cat-treat plant. Dried catnip is sold in pet stores; fresh catnip is a common backyard plant for cat-owning households; catnip-stuffed cat toys are foundational to the pet supply industry.
The plant is famously vigorous and self-seeding — once planted it often becomes a permanent garden resident. Catnip is also a robust pollinator attractor — bees, butterflies, and other insects find the small purple flowers highly attractive.
Related species in the genus Nepeta (often called “catmints” rather than catnip) — Nepeta racemosa, Nepeta × faassenii and others — produce less nepetalactone and less feline response, but are popular as ornamental perennial flowers in temperate gardens.
