1. Hemp seed oil is an oil extracted from flaxseed. Traditional Chinese medicine research shows that flaxseed is the best produced in the alpine region of northern China, and flaxseed oil is rich in A- linolenic acid. The analysis of nutritional physiological function of oil by modern nutrition shows that α -linolenic acid is the core substance to maintain the evolution of human brain. It is an important component of human tissues and cells and an essential fatty acid to maintain human evolution and health. It participates in the synthesis and metabolism of phospholipids and converts them into essential life-active factors DHA and EPA. It is the most basic and primitive substance in the process of life evolution. α -linolenic acid has a strong function of increasing intelligence, protecting eyesight, reducing blood lipid and cholesterol, delaying aging, resisting allergy and inhibiting cancer occurrence and metastasis. But it can't be synthesized in human body and must be taken in vitro. Once the human body lacks α -linolenic acid for a long time, it will lead to the functional decline of brain organs and visual organs and the occurrence of Alzheimer's disease, and it will also lead to the increase of the incidence of modern diseases such as hypertension, hypertension and cancer.

2. Flaxseed powder. Flaxseed is an edible powder, which can be eaten after being ground into powder. Also called flaxseed, flaxseed. Trait seeds are oblate, 4 ~ 7 mm long and 2 ~ 3 mm wide. The surface is reddish brown or grayish brown, smooth and shiny, with one end blunt and round and the other end sharp and slightly inclined. The hilum is located at the top depression, and the ridge is located at one side edge. The seed coat is thin and brittle, the endosperm is membranous and brown, and the cotyledons are yellow and white, rich in oil. It tastes like beans when chewed. The chemical composition contains fatty oil, and the main components are linolenic acid, linoleic acid, oleic acid, palmitic acid, stearic acid and other glycerides; It also contains eicosanyl ferulate, linarin, etc. Ring-opening Isolarch Resinol diglucoside is called ring-opening Isolarch Resinol diglucoside. This is a phytoestrogen very similar to human estrogen. Lignans mainly exist in flax seeds, which depends on flax varieties, climate and ecological conditions. Generally, it accounts for about 0.9%- 1.5% of the seed weight, which is 100-800 times higher than other 66 foods known to contain lignans. The taste is mild and sweet. Function is mainly used to moisten dryness and dispel wind. Used for pruritus, leprosy, dizziness and constipation. Chemical composition: lignans mainly exist in flax seeds, and their content depends on flax varieties, climate and ecological conditions. Generally, it accounts for about 0.9% ~ 1.5% of the seed weight, which is 100 ~ 800 times higher than other 66 foods known to contain lignans.
