Camellia oil (also known as wild camellia oil, camellia seed oil and camellia seed oil) is taken from camellia seed. The production process of camellia oil can be divided into hulling, sun drying, crushing, cooking, oil pressing and filtering. The whole process is physical, so it is really pure natural green edible oil. Tea oil does not contain additives such as erucic acid, cholesterol and aflatoxin. According to the test, the content of unsaturated fatty acid in tea oil is over 90%, oleic acid is 80-83%, linoleic acid is 7- 13%, and it is rich in protein and vitamins A, B, D and E, etc. In particular, its rich linolenic acid is necessary for human body but cannot be synthesized.

Camellia oil is extracted from Camellia oleifera seed, which is one of the oldest woody edible vegetable oils in China. China is the country with the widest distribution of camellia plants in the world, and it is also the largest camellia oil production base in the world. In addition, there are only a few countries such as Southeast Asia and Japan. The central producing area of Camellia oleifera is located in Dabie Mountain, Southwest China, Hunan and Gannan, which is a unique oil-bearing tree species in China. China is the origin of Camellia oleifera. Camellia oleifera grows in subtropical Nanling humid climate zone without pollution, and no pesticides and fertilizers are applied during the whole growth process.
