This system of medicine is believed to have been established by the Greek physician and philosopher Hippocrates (460–377 B.C.). Galen, Aristotle and Dioscorides made valuable contributions for its further development. The next phase of development of the Unani system of medicine took place in Egypt and Persia (Iran). The Egyptians had well-evolved pharmacy and were efficient in the preparation of different dosage forms such as oils, powder, ointment and alcohol. The Arabian scholars also played an important role in the development of this system. The Arabs were instrumental in introducing Unani medicine in India around 1350 A.D. The first institution of Unani medicine in India was established in 1872 as Oriental College at Lahore (then a part of India). National Institute of Unani Medicine was established at Bengaluru in Karnataka in 1983 in collaboration with the government of Karnataka, focusing on both academic and research and development requirements. Central Council for Research in Unani Medicine (CCRUM) is the premier agency involved in the research and development activities in the country.
