USES. The fruit is used by the Filipinos to intoxicate the

 when not only purgation but active irritation of the digestive

Applied to the skin it is a strong irritant causing rapid and 

 painful vesication. Great care should be exercised not to raise 

 the hands to the eyes after touching the oil, as serious inflamma-
