Minthostachys verticillata (Griseb.) Epling

The objective of this review is to provide an overall description of the taxonomy, morphology, uses, active principles and future prospects of the endemic Argentinean aromatic plant, locally known as “peperina” (Minthostachys verticillata). This species is an important plant that has been frequently enjoyed and used by the people of central Argentina. It was perhaps the initial interest of the indigenous population and settlers paid to this remarkable plant that led to uses and applications in many commercial products. Due to over-collection from the wild by a population increasingly interested in natural plant products, to date “peperina” has become a threatened species. This work seeks to generate and reignite interest in the use and conservation of this important medicinal and aromatic shrub from Argentina.
