| Description: | This study aims to evaluate local Algerian knowledge on the therapeutic uses of Artemisia herba alba and to analyze the chemical and biological properties of four traditional preparations derived from its aerial parts: a decoction, an infusion, and two types of poultices (one with honey and the other with garlic). The ethnobotanical survey revealed a use value of 178 among 196 informants from different Wilayas, highlighting the predominant use of decoctions and infusions for treating gastrointestinal disorders and respiratory diseases. Phytochemical analyses of the aerial parts of the plant powder revealed the presence of various families of secondary metabolites. The total polyphenol content, quantified using the Folin-Ciocalteu reagent, showed varying concentrations among the preparations, with the highest being in the decoction at 105.94 mg GAE/g of dry matter. The antibacterial activity was tested against four bacterial strains (Escherichia coli ATCC 25922, Staphylococcus aureus ATCC 25923, Pseudomonas aeruginosa ATCC 27853, and Klebsiella pneumoniae ATCC 700603) using the disk diffusion method. The results indicated that the infusion at 100 mg/ml had significant activity against S. aureus, with an inhibition zone of 15 mm. Furthermore, the antioxidant activity of the extracts was evaluated using the DPPH method. The IC50 values obtained were 31.45 μg/ml for the decoction, 159.68 μg/ml for the infusion, 159.1 μg/ml for the garlic cataplasm, and 362.62 μg/ml for the honey cataplasm. |
