Essential oil of the flowering shoot of Ammi visnaga was extracted by hydro-distillation method and the essential oil inhibitory effects have been studied by using well diffusion method on four bacteria consists of: Streptococcus viridans, Lactobacillus casei, Lactobacillus plantarum, Lactobacillus acidophilus (control: cetylpyridinium chloride 0.05%).
Effective essential oil against above mentioned bacteria suspension were studied by micro organism 10⁸ colony forming unit/ml (cfu/ml). 
Bactericide activity of essential oil of Ammi visnaga flowering shoot observed later of 24-48 hours. The zones of growth inhibition were as follow: Streptococcus viridans 35mm, Lactobacillus casei 50mm, Lactobacillus plantarum 35mm, Lactobacillus acidophilus 35mm and control 12mm.
