Abstract
This study aims to assess ethnobotanical knowledge in Kabylia, focusing on the traditional uses of medicinal plants. The purpose was to quantify the traditional knowledge of medicinal plants commonly used by local populations for treating a wide range of ailments, with a view to preserve the medicinal knowledge and the biodiversity of this area.
 Ethnobotanical data was gathered using a questionnaire. Semi-structured interviews were conducted with 69 key informants at six villages of Bouira province. A quantitative analysis by means of different indices including the informant consensus factor (FIC), use value (UV), relative frequencies of citation (RFC), and fidelity level (FL), was performed for the recorded medicinal plants.
 Overall, 136 plants species were recorded. Their uses in 10 disease categories were documented. They belong to 54 families, the most represented are the Asteraceae (18 species) and Lamiaceae (16 species). With 98 use reports, diabetes is the most treated ailment. The highest RFC values are recorded for Carthamus caeruleus (0.57) and Asplenium ceterach (0.52), indicating that these plants are the most preferred species used in study areas, to treat skin burns and kidney stones respectively. Plant with the highest use value is Lavandula stoechas (1.21), used to treat different digestive disorders (bloating, colon pain, and stomach ulcer). We found 13 medicinal plants having the highest FL value (100%), e.g. Rhamnus alaternus (jaundice), Lonicera implexa (weak eyesight), and Ulmus minor for treating skeletomuscular ailments. These latter are the most interesting species used in the treatment of a specific ailment category. The maximum FIC value (0.86) indicated that there was high agreement in the use of plants (e.g. Aristolochia fontanesii and Ophrys speculum) in genitourinary and reproductive ailment category among the informants.
 We highlighted the homogeneity of informant knowledge in medicinal plants appropriate for different ailment categories and the most preferred plant species used to treat each ailment category in the study area. By overstepping the limits of an orally transmitted pharmacopoeia, we aim to valorize the huge ethnopharmacology legacy of the region for promising pharmacological perspectives.

Summary
Considering its geographical position, Algeria has a great diversity of habitats and plants (4449 species and subspecies) (Dobignard & Chatelain, 2010– 2013). Algeria is recognized by its ancestral tradition about medicinal plant uses throughout the country, and the local traditional medicine continues to be an important source of remedies for primary healthcare. The Great Kabylia, a phytogeographical subdivision distinguished by Quézel & Santa (1962–1963), forms a part of the mountainous system of the Tellian Atlas in Northeastern Algeria It constitutes a homogeneous natural region by its physical features, climate, rich flora, dense population, language (Berber), and economy (Dahmani & Dahmani, 2004). The Kabylia, a Berber or Amazigh-speaking region of Algeria, is endowed with a rich ethnobotanical knowledge system on traditional medicine resulting from a prosperous wide history of interaction with the flora of this rural region. This area of Northern Algeria, which keeps its cultural identity (Hammiche, 2014), represents a unique social and Mediterranean Botany 43, e72688, 2022
