[From Salerne to Al-Andalus: practitioners of Kairouan's mark].

Ishak ibn imran, Ishak al-Isrâ'îlî and Ibn al-Djazzâr are famous practitioners of Kairouan of the ninth and tenth centuries. They are quoted among sources of their successors, practitioners and agronomists in Al-Andalus. We will study the uses of their treatises by means of examples and will conclude that these successors selected the contributions which characterize the medicinal herbs and describe their properties. It confirms the pharmacological orientation of the Andalusian medicine. The influence of the practitioners of Kairouan is not limited to the West Arabic world and spreads over the Latin world. We will remind that, in Salern and in the European Universities, their medical and pharmacological treatises are studied and used thanks to the Constantins' Latin traductions, although these were not totally accurate.
