Spectroscopic methods are generally used to measure the energy difference between various molecular energy levels and to determine the atomic and molecular structures. Vibrational spectroscopy is of unique value as an analytical technique for quantitative determinations. In the present study FTIR (Fourier Transform Infra Red) technique is used for the analysis Nilavembu Kudineer Churanam and Acetominaphen and has been recorded in the region 4000-400 cm -1 . The important vibrational assignments are discussed. Keywords: FTIR, Nilavembu Kudineer Churanam, Acetominaphen. _____________________________________________________________________________________________ INTRODUCTION Modern spectroscopic techniques find wide application in the field of pharmaceutical science. Vibrational spectroscopy has significant contributions towards the studies of structure and physico chemical properties of crystals and molecular system [1-3]. In the present study, a comparative study using FTIR spectroscopy has been applied to obtain the maximum amount of information from the vibrational spectra of Nilavembu Kudineer Churanam and Acetominaphen. Chikungunya Chikungunya (Makonde for "that which bends up") is an infection caused by the chikungunya virus. The disease features the sudden onset of fever two to four days after exposure. The fever usually lasts two to seven days, while accompanying joint painstypically last weeks or months but sometimes years. The mortality rate is a little less than 1 in 1,000, with the elderly or those with underlying chronic medical problems most likely having severe complications The virus is passed to humans by two species of mosquito of the genus Aedes: A. albopictus and A. aegypti. Animal reservoirs of the virus include monkeys, birds, cattle, and rodents. This is in contrast to dengue, for which primates are the only hosts. Chikungunya is a new emerging disease and it has not received sufficient coverage yet in the medical curricula of member states. Several indigenous drugs have been described in Siddha and Ayurveda for the management of inflammation, fever and other diseases. In the long term treatment of chronic disorders, like rheumatic diseases, combinations of different plants families and species active principles often exhibit remarkable potency and tolerance. It is well documented that the plant possessing anti-inflammatory property also having antipyretic and analgesic activities or vice versa. The nilavembu kudineer choornam (NKC) is a classical preparation used in the treatment of Chikungunya fever as Siddha medicine in Tamilnadu. Currently, no specific treatment for chikungunya is available. Supportive care is recommended, and symptomatic treatment of fever and joint swelling includes the use of nonsteroidal anti-inflammatory drugs such as naproxen,
