[Contribution of Persian physicians to the development of Islamic medicine]

In this article We have tried to reconsider the chronological appearance and influence of iranian physicians during periods before and after appearance of Islam until the penetration of contemporary medicine in Iran, e.i. up to 19th century AD. The priority has been put to mention names of scientists as well as their works and new thoughts, to expose, without exclusivity and national attitudes, part of efforts of iranian scientists in medical field. My main goal and intention was: first-to correct mistakes undertaken by some scientists who had seen books written in arabic language and so considered those scientific works as a part of arabic-islamic heritage, and second-to introduce and present iranian medical heritage of middle ages while Europe was in neglected dreams.
