Catnip, in large enough quantities, will also work as an attractant for large cats like lions and tigers. Europeans in the 1400s regularly drank teas made from catnip, with the herb earning a medicinal application for treatment of colic and flatulence.
The clusters of white or pale lavender tubular flowers with purplish spots are in bloom from July to September. The leaves are heart-shaped and toothed and covered with a soft, close down. Catnip contains volatile oil that cats find stimulating. The leaves and the flowering tops are used in herbal medicine. The other names of the plant are catnep, catmint, catâs-play, catrup, catwort, nip, nep, and field balm.
