Tung oil is extracted from the seeds of tung oil tree, which is unique to China. Tung oil tree is a genus of Euphorbiaceae, which originated in China and has a long cultivation history. It was recorded in the Tang Dynasty more than 1000 years ago. In the Yuan Dynasty, the Italian Kyle Polo was introduced, and tung oil gradually spread overseas.

Tung oil is an excellent dry vegetable oil, which has the characteristics of fast drying, light specific gravity, good luster, strong adhesion, heat resistance, acid resistance, alkali resistance, corrosion resistance, rust prevention and non-conductivity, and is widely used. It is the main raw material for making paints and inks. It is widely used as waterproof, anticorrosive and antirust coatings for buildings, machinery, weapons, ships, fishing gear and electrical appliances. It can also be used to make linoleum, oiled paper, soap, pesticides, emetic for medicine and pesticides.

Yunnan Province is an important producer of tung oil in China, and its annual output now ranks sixth in China. Production areas are distributed in Zhaotong, Wenshan, Qujing, Baoshan, Dali, Yuxi, Dehong and other places, and more than 50 counties in Guizhou, among which Zhaotong area and Wenshan Zhuang and Miao Autonomous Prefecture are the main production areas.

Tung oil is an industrial vegetable oil, which is extracted from picked tung trees by mechanical pressing. The whole process is a physical method. Tung trees are perennial woody trees, which grow in mountainous areas far away from cities. Strong ability to resist pests and diseases, and the whole growth process does not need fertilization and pesticides.
