Abstract: Sayyed Esmail Josjani (Gorgani) was one of the greatest scientists and physicians of Iran died in 1136 in merve. He promted writing medical book in Persian by authoring the valuable book of zakhireh kharazmshahi and Al Aghraz al tibia. Of course writing medical books in Persian was common before Avicennas time (980 - 1037). Zakhireh and Aghraz are like big and medium medical encyclopedia and even since the creation of the present Persian script. These books are the last and most important medical books in Persian. Like any other ancient book, some parts of these books are abolished but some other parts are valuable. However these books are remained to be unique as Persian medical books in the course of time. I have edited and corrected al - Aghraz al tibia (Medical goals) from several old manuscripts. There are seveval manuscripts of al - Aghraz (which is about 250000 words). To edit and correct this book, I have used five old important manuscripts of Aghraz and one manuscripts of zakhireh kharazmihahi. I have published this book in 2 volumes in 2005 - 2006. At the end of the second volume, I compiled a medical dictionary named Dictionary of Aghraz. The references of this work are various documents including manuscripts of published, old and new medical sources in persain or Arabic languages and some English or French documents.
