| Sumario: | Folk medicines are gaining great importance as information sources on traditional medicinal plants. The aim of this paper is the study of a plant traditionally employed by the Puna inhabitants: <i>Werneria poposa</i> Phil. Morphology of its secretory tissue and other histological diagnostic features, as well as the chemical composition of its essential oil, is described. Puna inhabitants use <i>W. poposa</i> mainly as an infusion for mountain sickness ('soroche'), stomach and hepatic disorders and cold. It is also used externally as a hot bath or unguent for rheumatic pains or traumas. Secretory tissues are schizogenous ducts in leaves and stems. Thirty-one components were detected in the essential oil by means of GC/MS analysis. Oil was characterized by the presence of high content of β-pinene (21.7%), α-pinene (5.5%), terpinen-4-ol (5.3%), α-terpinene (5.2%), β-phellandrene + 1,8-cineole (4.8%), isopulegol (4.8%) and β-citronellal (4.6%). At the present time, <i>W. poposa</i> is consumed as a medicinal plant, mainly in the northwest of Argentina, not being commercialized in the urban centers. |
