title: Ethnopharmacological survey of medicinal plants in Nor-Yauyos, a part of the Landscape Reserve Nor-Yauyos-Cochas, Peru.
abstract: OBJECTIVE
  To collect, analyze and evaluate the ethnopharmacologic knowledge in Nor-Yauyos in order to protect it. This paper reports the results of an ethnopharmacological survey on the uses of medicinal plants by inhabitants of the Andean region Nor-Yauyos, Peru. In this region one surviving ethnic group, the Jaqaru-Quichuas, has been identified.
  
  
  METHODS
  Field work was concluded between October 1999 and March 2000, using semi-structured questionnaire and participant observation as well as transects walks in wild herbal plant collection. Interviews with 68 informants (mean age: 54; 100% men, 0% women) were performed in 12 farmers' communities: Huancaya, Vilca, Vitis, Miraflores, Piños, Carania, San Lorenzo De Alis, Santa Rosa De Tinco, Tomás, Huancachi, Laraos and Huantán.
  
  
  RESULTS
  63 species of plants belonging to 29 families were reported. More than a half of reported plants were native, endemic of the studied area. Leaves and their mixtures were the most (67.26%) commonly used plant part. Most of the remedies were prepared in infusion, and 90.08% were administered orally. Most treated disorders were the gastrointestinal (18.59%) and respiratory ones (18.22%).
  
  
  CONCLUSIONS
  6 species (9.52%) without pharmacological references in international scientific literature, 21 species (33.33%) with 1-2 references, 16 species (25.40%) with 3-6 references, and 20 species (31.75%) that have been already widely studied were found.
