A total of 280 interviews were conducted with traditional health practitioners and knowledgeable villagers. Data were collected by semi-structured and structured questionnaires. Indices on Fidelity Level (FL), Use Value (UV) and Relative Frequency of Citation (RFC) were calculated. The ethnobotanical survey has identified 39 species representing 24 families. The most encountered medicinal plant families were Asteraceae and Lamiaceae. The following plant species were showed the high significant FL, UV and RFC: Artemisia herba-alba, Cistus creticus, Lavandula maroccana, Salvia lavandulifolia and Olea europaea.
