The emergence of drug-resistant organisms have been increasing globally; therefore, it is a burning need to find an alternative drug to get rid of the diseases caused by resistant strains. This study aims to evaluate the antimicrobial and wound healing activities of Loranthus acacia, Cassia obtusifolia and Cymbopogon proximus plants. All the plants were collected and extracted — by maceration method. Antimicrobial activities determined using standard ATCC strain for Gram-positive bacteria (Bacillus subtilis, Bacillus crew, Methicillin-resistant Staphylococcus aureus, Staphylococcus aureus) and Gram-negative bacteria (Shigella sonnnei, Salmonella Typhimurium, Salmonella typhi, Klebsiella pnuemoniae, Escherichia coli and Pseudomonas aeruginosa) following agar well diffusion method. Plants extracts were prepared as gel and investigated for in vivo wound healing activities in rats. Histological studies were performed on animals’ skin. The results showed that all tested plants have various antimicrobial and wound healing activities. Out of these plants, L. acacia exhibited the best result; it revealed a significant result for antimicrobial activities counter to all Gram-positive, Gram-negative bacteria and wound healing activities in comparing with the reference drug. Thus, it is essential to consider L. acacia as a prospective source in progress in the synthesis of a new antimicrobial drug for the treatment of infectious diseases.
