ABSTRACT
Medicinal plants constitute an effective source of both traditional and modem medicines. The emergence of drug resistant bacteria mandates the need for newer antibiotics. To evaluate the antibiotic effect of Hibiscus sabdariffa. Three medicinal plants have been selected for investigation of their antibacterial activities; Hibiscus sabdariffa. [Dried calyces], Cacia seyal var. seyal [fresh stem bark] and Sphaeranthus suaveolens var suaveolens [herbs] The extracts of these plants at concentration of 100mg/ml have been tested against seven strains of bacteria.; qualitative tests using the Agar Well Diffusion Method have been carried out. E coli showed higher resistance to the plant extracts whereas Pseudomonas aeruginosa is more sensitive. Hibiscus sabdariffa extracts showed extensive inhibition zone and were, therefore, effective as antibacterial ingredient
