Clinopodium is a genus of flowering plants in the family Lamiaceae. It is in the tribe Mentheae of the subfamilyNepetoideae, but little else can be said with certainty about its phylogenetic position.
The genus name Clinopodium is derived from the Latin clinopodion or the Greek klinopodion. These were names forClinopodium vulgare. The Greek klino means “a bed” and the Greek podion means “a little foot”. 
Various Clinopodium species are used as medicinal herbs. For example C. laevigatum is used in Mexico as a tea under the name “Poleo” or “yerba de Borracho” to cure hangovers, stomach aches, and liver disease.
