Saliva of the Dragon, Holy Medicine for Dai People  

Gurjunoil tree is a sort of large arbor tree. It can grow as tall as 40 to 50 meters and its wood quality is very good. 

Although gurjunoil tree is not a vivipary plant and only has one seed in each fruit, the seed begins to bud when it is still growing on the tree. When the seed grows to a certain extent, it will get rid of the mother tree and fall down. When it falls down, it has two tipped windsticks, which play the roles of a parachute, so that the already rooted seed could insert into the soil directly. This phenomenon explains that it has good adaptation capacity to its living environment. 

Gurjunoil tree is rich in resin contents. Its oil output rate is 0.06-1.0%; it has strong aroma and can be used as perfumes. If one cuts a small groove in the tree trunk and sets it on fire, the oil would begin to drop soon. The monks in the temples of Xishuangbanna regard gurjunoil tree as a heavenly tree and treasure among trees. They often use this kind of oil for burning the lamps in front of the Buddhas; the local people also use the oil to braise wounds. They believe it’s the saliva of the dragon and can cure various illnesses. 

Gurjunoil tree is a sort of symbolic tree in the tropical areas. Its native land is in Burma. However, it grows well in Xishuangbanna, and this explains that Xishuangbanna belongs to tropical areas and has rain forests in real sense.
