Linseed oil is an ancient edible oil, which is a fatty oil squeezed from the seeds of Juglandaceae. Flax is naturally hardy and suitable for growing in cold and arid areas in the west and north.

Origin of linseed oil

Because flax is only suitable for growing in cold regions, it is rarely known by people in other places. In addition, the yield and oil yield of flax are very low, so flax has not been widely promoted. Therefore, there are many wrong names about flax. In the southeast coast and other places, people have never seen flax or flax oil, so many people mistakenly call sesame oil flax oil.

Flax originated in the Mediterranean region and was introduced into the northwest minority areas of China in the Han Dynasty. Because of its unique habits, it can't grow in the tropics. In China, traditional flax is mainly planted in Huining, Gansu, northwestern Shanxi, northern Hebei, Ningxia and Inner Mongolia.
