Tetragastris. Tetragastris panamensis (Engl.) O. Kuntze. Bois Cochon, or Sucrier de Montagne, Fr. (Fam. Burseraceae.)—This native of Panama has been examined by Gaucher, Combemale and Marestang (France Med., October, 1888), who find in it an alkaloid and a resin. The extract of the root and sterna produces in the guinea pig rapid and considerable lowering of temperature, progressive paralysis, general convulsions, dilatation of the pupils, respiratory irregularity and cardiac paresis. The alkaloid was found to be a convulsive agent, acting upon the spinal cord. The resin, which seemed much more active than the alkaloid, acted as a paralyzant.
