In the earlier days there were no computers, printing presses and books, so unfortunately we do not have any documented records of when the first medicine might have been used. But we can reasonably guess that since in the early ages, manufacturing of modern day drugs would not have been possible, man must have used natural agents for healing. And can you think of these natural agents? Well plants or herbs were one of the first medicines that were used because they occurred naturally and man depended heavily on them for all requirements be it food, wood, shelter and so on. Remember that I am not talking about a few hundred years but several thousand years ago.
Infact the earliest assumptions of the use of herbs for medicines dates as far back as nearly 17000 years based on the radio carbon dating of Lascaux Caves in France, which depict the use of herbs as medicinal agents (Ruspoli, 1987).
Starting from those humble beginnings, later on medicine developed as a specialized science and all the major civilizations across the globe had their own unique system of medicine which was suited to the needs of their era. It would not be possible to discuss all these types in detail in this introductory article but I would try to take them individually in the coming articles. Some of these systems include Chinese medicine, Indian medicine, Persian medicine, Egyptian medicine and so forth.
