PHILIPPINE PLANTS USED AS SOAP SUBSTI- 

 TUTES AND SCOURING MATERIALS 



By William H. Brown 



In the Philippines there are a number of plants which con- 

 tain saponin and are used as soap substitutes, especially for 

 cleansing the hair. The most important of these is gogo {En- 

 tada phaseoloides) which is an important article of commerce. 

 Other plants have very rough leaves which are used as material 

 for scouring cooking utensils, etc., and as substitutes for sand- 

 paper.
