Using Catnip

Forager's Digest has a good article on using catnip. The article notes:

It’s been used mostly as a sleep aid to promote sleep and prevent nightmares but was also used in teas to relieve gas, cramping and colic. Poultices were made with catnip to relieve toothache pain and tonsillitis.

... The leaves are rich in oils and are used in antiseptics and make excellent insecticides. Catnip oil has also been used as bait for trapping large cats like mountain lions and bobcats.
