POISONOUS PHILIPPINE PLANTS 



By William H. Brown 



A large number of wild Philippine plants have been used for 

 poisoning fish, others yield arrow poisons, and still others are 

 used for poisoning dogs. The use of fish poisons is prohibited 

 by law, so that these plants are of more scientific than practical 

 interest. The use of arrow poisons is confined to a very few 

 people belonging to wild tribes, and is also of little practical 

 importance. For these reasons, local names and descriptions 

 have not been given for these plants. The following account 

 is little more than a list of poisonous plants known to have 

 been used in the Philippines.
