Catnip (Nepeta cataria) has a long history of use in traditional herbal medicine, particularly in European and North American traditions. Historically, catnip has been used as a remedy for various digestive complaints, including cramps, colic, and flatulence, as well as for its mild sedative properties. The traditional justification for its use in treating cramps and spasms comes from its content of volatile oils, such as nepetalactone, which are thought to have mild antispasmodic effects. Herbalists have used catnip in teas or tinctures to help relax smooth muscle tissue, particularly in the gastrointestinal tract, and to ease menstrual cramps.

However, scientific evidence supporting these uses remains limited. There are a few animal studies and in vitro experiments suggesting that catnip extracts may have smooth muscle relaxant properties, but robust clinical trials in humans are lacking. As a result, while the traditional use is well-documented, and there is some preliminary pharmacological support, the overall scientific evidence is weak. Most modern herbal texts acknowledge catnip's historical role in easing minor spasms and cramps, but also note the lack of strong clinical data. Thus, its use for cramps and spasms is justified primarily by tradition, and it is generally considered safe when used in moderation.
