Catnip (Nepeta cataria) has a long history of traditional use as a mild sedative and sleep aid in herbal medicine, particularly in European and North American folk practices. Historically, catnip tea was given to children and adults alike to soothe restlessness, nervousness, and promote sleep. Herbalists from the 17th to 19th centuries cited catnip as beneficial for “restless sleep” and as a gentle remedy for insomnia or disturbed rest.

The evidence supporting catnip’s use for sleep is largely anecdotal and based on historical tradition. While modern scientific studies are sparse, the plant contains compounds such as nepetalactone (responsible for its effect on cats) as well as mild volatile oils and flavonoids. These constituents are believed to have mild sedative, antispasmodic, and calming effects on humans, though the mechanisms are not well understood. Some small, older studies and animal research suggest potential sedative actions, yet these findings are neither robust nor widely replicated.

In summary, the use of catnip for sleep disturbances is primarily justified by traditional use rather than scientific validation. The overall quality of evidence is low (rated 2), and more rigorous clinical research would be required to confirm efficacy and establish safe dosing for human sleep disorders.
