It has experienced the severe test of ecological environment changes during glacial period, interglacial period and Himalayan orogeny period, and has strong vitality. At present, it is widely distributed in Qinghai-Tibet Plateau, Siberia and other regions. It was found that seabuckthorn fruit contained 190 kinds of effective components. Include 6 fat-soluble vitamins, 22 fatty acids, 42 lipids, 36 flavonoids and phenols. Seabuckthorn is the most active plant in nature and the crown of vegetative plants. It has many functions such as preventing cardiovascular diseases, inhibiting proliferation of various tumor cells, promoting cell degeneration, improving human disease resistance, protecting liver, resisting aging, promoting gastrointestinal health, resisting burns and scalds, beauty beauty, preventing and relieving neurasthenia, resisting radiation, resisting inflammation and promoting granulation.

Seabuckthorn is rich in vitamin C. The content of vitamin C in seabuckthorn is the highest among all vegetables and fruits: 2-3 times that of kiwifruit, 6 times that of orange, 20 times that of hawthorn, 80 times that of tomato and 200 times that of apple.
