An ethnobotanical and floristic study of medicinal plants was carried out in the area of Doui Thabet (Saida, Western Algeria). It was done in order to compile a catalog (list) of medicinal plants in this area and to collect as much information as possible about the various therapeutic uses practiced by the population of the agglomerations in this zone. Using 100 questionnaire cards, the ethnobotanical survey was conducted during three campaigns (2017-2019). The results we obtained allowed to identify 73 medicinal plants which are divided into 62 genera and 31 families among which three families clearly dominate this flora: the Asteraceae, Anacardiaceae and Lamiaceae, in particular. Our results show that seeds and hardwoods are the two most used parts. In addition, digestive disorders occupy the first order with a rate of 30%, followed by uro-genital disorders (15%) and cutaneous affections (10%). These results constitute a very important source of information and make it possible to valorize the taxa with large consumption on the one hand and to release the threatened species with the aim of preserving them.
