History
'The different species of Coix bear the Sanskrit names of Gavidhuka, Gavedhu, and Gavedhuka. They are mentioned in Vedic literature, and appear to have been one of the cereals which were cultivated by the Arians on the hill-slopes of the Himalayas. They are still cultivated by the hill-tribes in the Kbasia and Naga Hills and in Assam and Burma, where they arc known by tho vernacular names of Kasi, Kulese, Kalinsi, Kyoit, &c, and are used as a food-stuff. The wild form, common in the plains, is only used for medicinal purposes, and is considered to be strengthening and diuretic. The Arab travellers in the East became acquainted with the seeds
and named them Darau Daud "David's tears," and afterwards Darau Aydb "Job's tears." Es-Saghani, who died about the year 1260, mentions them in the Obab as a well-known strengthening and diuretic medicine. The Arabs introduced the plant into the West, and it has become naturalized in Spain and Portugal, where it is still known as Lagrima de Job. European botanists have rather inappropriately given the name of Coix to this genus, Coix being the name of a kind of palm growing in Africa and mentioned by Theophrastus and Pliny. (Pharmacographia Indica, Dymock, 1893)
