Feverfew (Tanacetum parthenium) belonging to the family of Asteraceae has a great quality of curing variety of disorders. Those include migraine headaches, asthma, cancer, painful menstrual cramps, rheumatoid arthritis and many other ill complications. The seeds of feverfew (Tanacetum parthenium) were got through online from Assam, India. The obtained seeds were crushed using ethanol and the extract with 1mM silver nitrate in the ratio 1:4 was used for synthesis of Nanoparticles under agitation at 60°C. The colour change to red was detected and the further analysis with UV spectrophotometer, FESEM and X-RAY Diffractometer were done for characterizing the Nanoparticles. Red colour Nanoparticles yielded highest absorbance at 400nm followed by the particle size range at FESEM was between 12-35nm showing X-ray diffraction as FCC silver crystals at planes (111) and (200) at 36.183° and 46.233°. Thus, the silver Nanoparticles are synthesised and characterized for the further use of nano drug delivery or for the genetic analysis in curing the diseases.
