title: Ethnobotanical study in the Madonie Regional Park (Central Sicily, Italy)--medicinal use of wild shrub and herbaceous plant species.
abstract: BACKGROUND
  This paper illustrates the results of an ethnobotanical study carried out in the Madonie Regional Park (Central Sicily, Italy). It specifies the medicinal uses of plants in the study area and contains the results of a quantitative analysis carried out for the first time in an area noted for its high degree of biodiversity. It also introduces 28 species not previously accounted for in the area of study for their medicinal uses, highlighting Silene flos-cuculi L. Greuter & Burdet, little known as medicinal in the Mediterranean area.
  
  
  OBJECTIVE
  To understand to what extent current knowledge on medicinal-use plants is still an element of the culture within the elderly population of the Madonie Regional Park.
  
  
  METHODS
  The information was obtained using a semi-structured interview format performed on 150 informants over the age of 60 who were considered experts in plants and rural traditions. The taxa were identified and the results were analysed also using a range of quantitative ethnobotanical indices.
  
  
  RESULTS
  A census was made of 174 wild plant species, 100 of which with medicinal and veterinary uses, belonging to 49 botanical families. Of the 170 endemic species found in the Madonie Regional Park, only 2 species were cited in this study for medicinal purposes. Most of the species were used against dermatological diseases, general health and metabolic disorders. The leaves were the most-used parts of the plant and the most common preparation methods were decoction and infusion. The level of knowledge on medicinal uses of the plants was not found to be high within the elderly population, demonstrating an ongoing process of cultural erosion.
  
  
  CONCLUSIONS
  Only very few medicinal uses are widely known by all the informants and, on many occasions, a specific medicinal use was cited by only very few people. Further study is required in order to find out to what extent knowledge on the medicinal use of plants is still present in the younger generations in this area of Sicily, and what methods might be adopted in order to halt this gradual loss in knowledge.
