About Minthostachys verticillata (Griseb.) Epling
Minthostachys verticillata is a flowering plant species that belongs to the mint family, Lamiaceae. It is commonly called peperina. It is the only species from the genus Minthostachys that has been recorded in Argentina, where it grows in the country's northwestern and central regions. It is likely the most economically important species in its genus, because it is widely collected to obtain its essential oils. Researchers have repeatedly studied these essential oils to investigate their composition, variability, and potential pharmacological effects. Because experts hold differing opinions on how to define the circumscription of species in this genus, Minthostachys verticillata is sometimes grouped together with other species under the broad collective name Minthostachys mollis.
