Crazy for “Catnip” March 14, 2011

“Catnip,” a feline favorite, is a perennial herb in the mint family

Nepeta cataria, more commonly known as “Catnip” is a perennial herb that belongs to the mint family.  This herb packs a powerful punch to cats by provoking a state of euphoria usually lasting several minutes (video).   Many times herbs are utilized for medicinal purposes , but “catnip” obviously doesn’t affect human beings in the same way that it does cats.  What is it about “catnip” that provokes a euphoric response in cats but not in human beings?

The chemical component responsible for the effects of catnip

Studies suggests that the chemical nepetalactone found in “catnip” is primarily responsible for triggering the response in cats.  Nepetalactone evokes a psychosexual response in both male and female cats by mimicking a sex pheromone found in cat urine.

Bugs aren’t so crazy for “catnip”

The chemical nepetalactone may attract felines, but does quite the opposite to some insects.  Researchers at Iowa State University found that the chemical nepetalactone is a successful repellent of mosquitoes, flies, and cockroaches.  Particularly, the research team at Iowa State found that a solution of catnip extract is comparable in effectiveness to a ten times more concentrated solution of DEET.  Research in finding alternatives to repellents or pesticides, such as DEET, is very important because chemicals contained in most pesticides pose a serious threat to human health and the environment.  Unfortunately, the essential oils in “catnip” are extremely volatile and have a potent, but short lived repelling effect.  Further research in reducing its volatility is essential before such repellents can be used by the general public.

Catnip’s properties are multifunctional

Interestingly, researchers at the Max-Planck Society found that birds that used different types herbal plants in their nests produced offspring that were less prone to infestation of mites.  This study indicates that other herbs may have the same insect-repelling power as “catnip” and that organisms other than humans are using this characteristic to their benefit.


In the future, the active ingredient, nepetalactone, may be found in the bottle of repellent you spray on yourself or the pesticide you sprinkle on your plants.  You can be sure that the product you are using is much safer than the products of old, but if you have cats you must beware!  Such products will still provoke the same euphoric response caused by “catnip” sold in pet stores.
