The Catnips, Nepeta spp.
At least three species of catnip smell of cat urine:
There are dozens, if not hundreds, of catnip species. Also, some Dracocephalums, Glechoma hederacea and some Calaminthas used to be Nepetas.
There is a lemon-scented cultivar of true catnip, Nepeta cataria 'Citriodora'. It looks exactly like true catnip, but it has the scent of and can be used like lemon balm.
Herbally, catnips are used as relaxants, nervines, sedatives, and as antispasmodics. Use them in tea if you have trouble sleeping, if you're stressed, and if you have menstrual cramps, or gut cramps from something you've eaten.
The root of a completely unrelated plant, valerian, has a similar effect on cats, but it is not known what constituent in valerian would be responsible for this behavior.
Classification: The catnips belong to the mint family, Lamiaceae.
