This study documented 50 medicinal plant species from 29 botanical families used by herbalists in Relizane, Algeria. The Lamiaceae family was the most represented (22%), followed by Asteraceae and Apiaceae (6% each). Prominent species included Ptychotis verticillata Duby (UV=0.96), Juniperus communis L. (UV=0.91), and Thymus vulgaris L. (UV=0.88). High Informant Consensus Factor (ICF) values were recorded for infectious or parasitic diseases and mental problems. These results emphasized the significance of traditional knowledge in healthcare and identify promising candidates for further pharmacological research.
