Nepeta cataria, commonly called catnip, is an ancient member of the mint family. It has been used in western folk practices for millennia, and is loved for its gentle, calming properties. Herbalists and parents often brew this child-friendly herb into a soothing tisane, but it can also be taken internally as a tincture. For topical use, catnip can be infused in oils, or used as an essential oil or hydrosol to bring an herbaceous, relaxing scent to body care products. Perhaps, however, catnip is best known as the herb most loved by our feline friends.
