Nowadays people are adopting our tradition of Ayurveda, not in India but in other foreign countries are also showing their interest in Ayurveda. Herbal medicines are more effective than allopathy or homeopathy.In the field of nanotechnology, we can research the antibacterial characteristics of herbs and improve their effects by working with nanoparticles.In this study, we have synthesised individual and combined silver nanoparticles of swertia chirata, cinnamomum verum, thymol crystal, Tribulus terrestris, curcuma longa, and tinospora cordifolia to examine the antibacterial effects of these plants.we have done characterization methods for silverver nanoparticles like UVVIS , SEM( scanning electron microscope).We have isolated pathogenic bacteria from blood sample and did characterisation method like gram staining to identify microorganism whether it is gram positive or gram negative. We have seen the effect of the antibacterial properties of these herbs on isolated pathogenic bacteria from blood and E. coli.
