Siggel p. 25 mentions the two Arabic variants: ﺟﺪﻮﺍﺭ /ğadwār/ = ﺯﺩﻭﺍﺭ /zadwār/ Wz. v. Curcuma Zedoaria (Zingiberac.) Zitwer-Wz. {i.e. "zedoary root"}, which correspond to Simon's ''zeduar'' and Avicenna's ''geduar'', although Avicenna uses ''zeduar'' as well, see below:

Siggel (1950: 25) mentions the two Arabic variants: ﺟﺪﻮﺍﺭ /ğadwār/ = ﺯﺩﻭﺍﺭ /zadwār/ Wz. v. Curcuma Zedoaria (Zingiberac.) Zitwer-Wz. {i.e. "zedoary root"}, which correspond to Simon's ''zeduar'' and Avicenna's ''geduar'', although Avicenna uses ''zeduar'' as well, see below:
    
Goehl: Canon Avicennae, liber secundus, ''Capitulum'' 745 ''De zedoaria'' (annotation: gieduar} he describes the plant and states its medicinal uses; and in ''Capitulum'' 754 ''De zeduar'', he says: ''Zeduar quid est''? ''Inquit Dioscurides: est algeduar'' {annotation: ''algieduar id est zedoaria''}, ''secundum quod existimo'' -

Zedoary, ''Curcuma zedoaria'' (Christm.) Roscoe [[http://en.wikipedia.org/wiki/Curcuma_zedoaria]], [[https://www.google.co.uk/search?q=Curcumazedoaria+images&tbm=isch&tbo=u&source=univ&sa=X&ei=0kpFUqDqNqu00QXW2YHoDg&ved=0CC4QsAQ&biw=1440&bih=779&dpr=1]], is a perennial herb of the ginger family, native to India and Indonesia. The plant produces a rhizome which is used as a spice and medicinally. Zedoary was unknown in Antiquity and was introduced into Europe by the Arabs around the sixth century and is first mentioned by Benedictus Crispus (†725/35). Although the plant is nowadays almost completely replaced by ginger it seems to have played a part in the medieval medicine chest.
