UPAS , a Javanese word meaning See also:

poison, and specially applied to the poison derived from the See also:gum of the anchar See also:tree (Antiaris toxicaria), a member of the fig-See also:family (See also:Moraceae), and a native of the Sunda Islands, which was commonly used to envenom the darts of the natives. The name of the upas tree has become famous from the mendacious See also:account (professedly by one Foersch, who was a surgeon at Samarang in 1773) published in the See also:London See also:Magazine, See also:December 1783, and popularized by See also:Erasmus See also:Darwin in " Loves of the See also:Plants " (Botanic See also:Garden, pt. ii.). The tree was said to destroy all See also:animal See also:life within a See also:radius of 15 M. or more. The poison was fetched by condemned malefactors, of whom scarcely two out of twenty returned. All this is pure See also:fable, and in See also:good See also:part not even traditional fable, but See also:mere invention. The milky juice of the tree contains an active principle named antiarin, which has been recommended as a cardiac stimulant. It is without any properties, however, that entitle it to clinical employment. The tree is described as one of the largest in the forests of See also:Java, the straight cylindrical See also:stem rising without a See also:branch to the height of 6o to 8o ft. It has a whitish bark and on being wounded yields plentifully the milky juice from which the poison is prepared. For a full account of the tree, see See also:Bennett and See also:Brown, Plantae Javanicae rariores, p. 52 (1838).
