Review of the situation of Hedeoma multiflora Benth. (Peperina de las Lomas): an aromatic-medicinal Argentine species at risk

Abstract

Aromatic and medicinal plants (AMPs) have great potential for the synthesis of secondary metabolites, which are used by the pharmaceutical and food industry. In addition, they are part of ancestral medicine and the livelihood of many families in regional economies. Argentina has a high number of AMPs. However, the intensive extraction system (overexploitation), together with other anthropic actions, puts them at risk. The "peperina de las lomas" (Hedeoma multiflora Benth. (Lamiaceae)) is within this problem. This native species, xerophyte, is distributed in central Argentina, in stony mountain areas, forming small bushes. In this work, the existing information of the species was collected, covering from its environmental problems to the most recent investigations, oriented towards its conservation and the development of its germplasm. These data will serve to promote activities aimed at preventing the degradation of this resource and promoting its sustainable use.
