MANCHINEEL.-The Hippomane Mancinelli, Linné, a West Indian tree possesses poisonous properties. Its fruit, resembling in color and size our common apple, is said to poison fish when placed in the water. The tree abounds in acrid, milky juice, the poisonous principle of which is volatile. Fat, resin, caoutchouc, volatile oil, gummy material, and mancinellin are, according to Ricord-Madianna, constituents of manchineel. The juice of the tree is highly irritating, causing vesication, and if in contact with the conjunctiva, producing a violent conjunctivitis.

Both the juice and the fruit produce inflammatory gastro-intestinal symptoms, with emeto-catharsis.
