Unfortunately, resistance has been reported to a vast majority of currently use drugs. The objective of this study was to search for new therapies from plant products for the sustainable management of tuberculosis and <i>S. aureus</i> infections. <b>Materials and Methods:</b> Crude extracts were obtained by sequential maceration of dry powdered plant material in three solvents; hexane, dichloromethane and methanol. Phytochemical screening to identify active constituents in the crude extracts was done by conventional methods. The antimycobacterial and antimicrobial activity on <i>M. tuberculosis</i> control strain H37Ra and a clinical isolate of <i>S. aureus</i> respectively, was evaluated at eight different concentrations using the microplatealamar blue assay. Cytotoxicity of the active extracts was evaluated on monkey kidney epithelial cells and assessed using the MTT/formazan assay. <b>Results:</b> Twelve crude extracts were obtained, the hexane extract of <i>Sanseviera liberica</i> rhizomes (P3rH) showed antimycobacterial activity with a minimum inhibitory concentration (MIC) of 1 mg/mL. The hexane and methanol extracts of <i>Emilia coccinea</i>, P2H and P2M respectively, showed antimicrobial activity with MICs of 500 ¦Ìg/mL and 1000 ¦Ìg/mL respectively.
