Linseed oil is one of the best sources of fatty acids. Omega-3 fatty acids are "good" fats lacking in western diets. Because many studies in Europe have shown that it can shrink cancer tumors and has a strong anti-cancer effect on breast cancer, prostate cancer and lung cancer cells, scientists at the National Cancer Institute in the United States are interested in all omega-3 fatty acids, especially linseed oil.

Flaxseed oil is made from flaxseed and belongs to flaxseed family, also called flax. Originated in East India, Zhang Qian brought flax back to China via the Silk Road in the Han Dynasty, and it was mainly planted in the old Xiongnu area where "Hu people" gathered, hence the name. Flaxseed is a traditional oil crop in China. Flaxseed is divided into oil flax, oil flax and fiber flax. Linseed for oil is mainly produced in Songnen Plain of Changbai Mountain in Heilongjiang Province, Liupan Mountain in Inner Mongolia, Ningxia and Zhangbei in Zhangjiakou Bashang. Inner Mongolia has the largest grassland distribution area, and there is also a small amount of reclamation in Northeast China. Although flax has the habit of barren resistance, as an oil flax, three conditions "cool climate, fertile soil and sufficient sunlight" are indispensable. After thousands of years of cultivation by local people, it is found that the natural ecological environment in northwest China, such as balanced temperature difference between day and night, fertile soil and abundant sunshine, is most suitable for planting special oil crops such as flax, which belongs to the national industrial pollution-free area. The oil content of linseed oil produced in northwest Xinjiang, Gansu and western Inner Mongolia is above 56%, among which the content of α -linolenic acid is much higher than that in other planting areas, and the activity of linseed oil is also the highest. Xinjiang, Gansu, Ningxia, Inner Mongolia, Shanxi and other places, also known locally as linseed oil, were mainly introduced to China from Zhang Qian in the Middle East during the Han Dynasty. Cold pressed linseed oil is rich in α -linolenic acid, which is the most effective way to supplement linolenic acid.
