Bacterial resistance to chemical antibiotics, have been elevated irregular consumption of herbs in the society. Groceries are the closer source for provision of herbal medicine in our society. In this study we evaluated the effect of three grocery herbs: Chrysanthemum parthenium , Astragalus hamosus and Teucrium polium on the growth of Klebsiella pneumoniae in vitro based on their antibacterial effect in traditional medicine. Material & Methods: In this study we used reference bacteria which prepared from microbiology laboratory of Guilan university of medical Sciences. Effect of hydro-alcoholic extract of all three herbs on growth of bacteria has been evaluated by minimal inhibitory concentration (MIC) and serial dilution method and compared with control tubes. Results: Extract in range of 10 to 400 µg/µl of all three herbs didn't avoid from growth of bacteria in MIC (Minimal Inhibitory Concentration). Concentration 200 µg/µl of Astragalus hamosus has an intermediate suspicious effect but it was not significant. Conclusion: Although herbs are suitable drugs for prevention and treatment of diseases in traditional medicine but there is no surveillance on the dispensation of herbs in groceries. Comparison of effect of natural confirmed herbs and grocery herbs in the same name is suggested.
