Therapeutics and Pharmacology: Nepeta is a traditional remedy for colds and flu. A powerful diaphoretic in any feverish condition, it is particularly useful where there is a feeling of congestion in the airways, sinuses or middle ear. It is also a safe remedy for the infectious diseases of childhood, such as measles. Its mild sedative action will help a restless child to sleep. As an antispasmodic carminative, it relieves dyspepsia, flatulence and colic, and is an excellent remedy for the treatment of diarrhoea in children, where its sedative action adds to its generally relaxing properties. In the USA it has been used as an enema to cleanse and heal the lower bowel.

Additional Comments: In France, the leaves and young shoots of catmint are used as a seasoning. Mrs. Grieve states that the young tops, made into a conserve, can be administered for nightmares. Culpeper recommended the juice of the plant drunk with wine for bruises, the bruised leaves for haemorrhoids, and a decoction used as a shampoo for scabs and scurf. Cats are attracted to Nepeta but rats hate it. The leaves give a mild euphoria when smoked.
