Introduction: The study provides significant ethnobotanical information on plant resources traditionally used in the Javor Mountain region (eastern Bosnia and Herzegovina), aiming at identifying medicinal plants and collecting information concerning the specific methods of their therapeutic application. Methods: A qualitative anthropological method using a semi-structured questionnaire was used to interview 70 people. The relative importance of wild plant species, as reported by the informants, was assessed by the quantitative methods: use-value (UV), cultural importance value (CIV) and Shannon-Wiener index. Also, the level of homogeneity among information provided by different informants was calculated by the Informants' Consensus Factor (FIC). Results: 73 plant species with medicinal properties were collected, identified and their methods of preparation and uses were recorded. Asteraceae, Lamiaceae and Rosaceae have the greatest species diversity. The most commonly used are Hypericum perforatum, Mentha x piperita, Sambucus nigra and Achillea millefolium, with UV over 0.9. The most frequently used plant parts are the aerial part (29%) and the leaf (26%), while infusion being the most common way of preparing herbal remedies (57%). The plant most appreciated by the people interviewed was Hypericum perforatum used to treat skin complaints, haemorrhoids, moderate depression, gastrointestinal ailments and respiratory infections. Also, phytotherapeutic use of Veronica officinalis rhizome in jaundice treatment, as well as utilization of Prunus domestica bark for cavity protection were noted. Conclusion: The results of the current study may be significant in rural development programs in the Javor Mountain region, in aiming to foster community-based strategies of management of natural resources.
