According to Professor DuMez: * 



The oil appears to resemble olive oil very much in its physiological 

 action. Administered to dogs in doses of 1.5 to 3 cubic centimeters per 

 kilogram body weight, it acts as a mild laxative. It is nontoxic and has 

 no irritating action. It can be used in the same manner as olive oil and 

 should be especially useful for culinary purposes. 



Sterculia foetida is a spreading tree reaching a height of 20 

 meters or more. The leaves are crowded at the ends of the 

 branches. They are compound, having seven to nine leaflets 

 borne in a whorl at the end of the petiole. The leaflets 

 are 12 to 18 centimeters long. The flowers are rank-smelling, 

 dull yellowish or purphsh, and 2 to 2.5 centimeters in diameter. 

 The fruit is large, woody, red, nearly smooth, ovoid, and about 

 10 centimeters long. It contains 10 to 15 seeds, which are about 

 2 centimeters long. 



The wood of Sterculia foetida is used for cheap and tem- 

 porary construction, box-lumber, etc. It is rarely cut for lum- 

 ber except occasionally by larger operators, with the cheapest 

 grade of miscellaneous lumber. The wood is soft to very soft 

 and light to very light. The durability is very poor. 



This species is found throughout the Philippines, and is 

 distributed from eastern Africa to India through Malaya to 

 northern Australia.
