Hygrophila auriculata, a perennial angiosperm of Acanthaceae, broadly distributed semi-aquatic herb in India, is creature used as vegetable in several states like Odisha, Chhattisgarh & West Bengal. The pre-flowering or flowering succulent aerial parts are boiled and consumed by the rural people of these states to increase the haemoglobin level. This herbal therapy does not have any side effects with confirmed effectiveness. Silver was of a particular concern for this progression due to its evocative chemical and physical properties. Silver nanoparticles have attained special place in the area of nano technology because of their antimicrobial and biomedical applications, and they are rich sources of various medicinally important substances. The aqueous silver ions are reduced to silver nanoparticles when exposed to seeds extract. We discussed on the Synthesis and characterization of silver Nanoparticles by green synthesis method. It attempt was made to silver Nanoparticles is prepared by using a medicinal seed of Hygrophila auriculata, silver nitrate as used to synthesis the silver Nanoparticles by using aqoeous extract of Hygrophila auriculata. The synthesized silver nanoparticles from Hygrophila auriculata seeds and were characterized by various other techniques viz. Fourier-transform infrared spectroscopy (FTIR), UV, X-ray Powder Diffraction (XRD) and SEM.
