Semi-structured interviews were carried out in the local communities between 2009 and 2010 within the Monti Sicani Regional Park with local people retained experts in rural traditions. A total of 230 people were interviewed about their knowledge on medicinal plant uses. Local plant uses were evaluated using ethnobotanical indices (e.g., cultural importance index, ethnobotanicity index, informant consensus factor) and then compared with uses in other localities in Sicily, Italy and the Mediterranean basin.
Local communities currently use a total number of 108 wild species (43 families) as remedies for human and livestock ailments. The majority of plants are used in the treatment of articular, skin and gastrointestinal problems. The use of some species is limited to Sicily (e.g., <em>Rhus coriariaem> L., <em>Athamanta siculaem> L., <em>Senecio delphinifoliusem> Vahl).
The research shows an ongoing process of cultural erosion in an advanced stage, but results still highlight an interesting cultural identity as regards the local folk medicine.
