It is believed that the practitioners of Siddha, the ancient Indian system of medicine, utilized the basic tenets of nanotechnology in preparing medicines for the treatment of various diseases. The Siddha preparation 'Bhasma' (Parpam), which is widely recommended for the treatment of a variety of chronic ailments, is an ash obtained from some metallic compounds through incineration. When the 'bhasma' particles were analysed recently through latest instruments, they fell in the range of nanoparticles. Revealing these facts at a UGC-sponsored seminar organized by Patna University chemistry department Sanjay Kumar, Rakesh Kumar Singh and others of Aryabhatta Centre for Nanoscience and Nanotechnology, Aryabhatta Knowledge University, and Sweety Supriya and Manoranjan Kar of IIT Patna said 'Abhraka Bhasma', a derivative of mica, is an ancient nanomedicine. It is widely used in cases of pernicious and sickle cell anaemia, Bells Palsy, hepatic dysfunction, leukaemia, cystic fibrosis and cervical dysplasia and it is known for its penetrative and spreading property in the whole body and various micro tissues."We have synthesized 'Abhraka Bhasma' through X-ray diffractometer, vibrating sample magnetometer, scanning electron microscopy and Photoluminescence spectrometer and found that it is in nanocrystalline form and may be considered as a nanomedicine," they said. They further observed that the 'bhasma' cannot only be used as a very good nanomedicine but is also applied for various technological innovations for its magnetic and luminescence properties. This preparation is natural and eco-friendly as well as cost-effective, they added.
