Maceration to extraction was used to conduct this research in four methods using distilled water and alcohol as solvent and finally these extractions was used to measuring halos of blight. Streptococcus pyogenes bacteria were standard and the impact of extractions using impregnating discs on bacteria in Muller-Hinton agar in plate was conducted and their influence compared with required antibiotics and measuring halos of blight were accomplished, which were confirmed by MIC, MBC and FIC. The required extractions from onions and figs obtained by maceration which surveyed as synthetic and single on standard S. pyogenes bacteria and their impact on the tested bacteria in some resulted methods were logical compared to 8 used antibiotics and compared with some antibiotics was more, equal and less. Onions and figs extracts, both singly and specially synthetically by maceration on S. pyogenes bacteria are the causes of lung infections which have antibacterial feature. Onions and figs extracts synthetically with distilled water traditionally and the extant of drench for 10 days is more influential and has big halo of blight than 8 kinds of antibiotics such as gentamicin, neomycin, azithromycin and erythromycin. Also hypothesizes have been offered to explain the mechanism of their antibiotics feature. The FIC parameter result showed that, combination of figs and onions extractions had synergistic effect. Therefore the combinations of the two extractions are more effective.
