INTRODUCTION 
Lumbang oil is obtained from the nuts of Alewrites moluccana, 
which is a large tree reaching a diameter of 80 to 160 centi- 
meters. The genus Alewrites contains a number of species 
which yield nuts having a valuable oil. Perhaps the best known 
of these oils is Chinese wood oil (tung oil). This is derived 
from at least two Chinese species of the genus, Alewrites fordii 
Hemsley and Aleurites montana Wilson, which do not occur in 
the Philippines. Tung oil, which has properties quite similar to 
those of Philippine lumbang oil, has been investigated exten- 
sively. It is used in large quantities for the preparation of 
paints, varnishes, linoleum, and for other similar purposes. In 
the Philippines, oil is obtained from the nuts of two species of 
the genus Aleurites. Oil from Alewrites moluccana is known as 
lumbang oil, while that obtained from Aleurites trisperma is 
called baguilumbang. The oil now obtained in the Philippines 
from the genus Aleurites is almost entirely the product of 
Aleurites moluccana which is fairly abundant in a wild state in 
many parts of the Philippines and is also planted. Alewrites 
trisperma is reported from many localities but is probably not 
So abundant. Both species can be grown readily in plantations.
