The Arab travellers in the East became acquainted with the fruits and named them “Damu D´aud” (David’s tears) and afterward Damu Ay´ub (Job’s tears). Es-S´agh´ani, who died about the year 1260, mentions them in the Ob´ab as strenghtening and diuretic. The Arabs introduced the plant in Spain and Portugal, where it became naturalized as “lagrima de Job”. The fruits of Coix lacryma-jobi L. are used as food, to promote urination, appetite, to combat fever, to treat anxiety, rheumatism, dropsy, gonorrhea and to remove warts throughout China, Japan, India and Southeast Asia.
