The invention discloses brain-nourishing and intelligence-improving 
camellia oil. The brain-nourishing and intelligence-improving 
camellia oil is prepared from the following raw materials in parts by weight: 90 to 100 parts of 
camellia oil, 2 to 5 parts of salmon oil, 3 to 6 parts of 
wheat germ oil, 1 to 3 parts of 
safflower seed oil, 1 to 3 parts of maize oil, 0.2 to 0.5 part of fructus

nutrition and the like of the camellia oil are greatly improved, and any harmful components are not added, therefore, the oil belongs to green and 
healthy food; the prepared product has high content of 
unsaturated fatty acid and keeps beneficial components such as vitamins, 
calcium and 
linolenic acid; trace elements can be supplemented, anti-oxidization is achieved, the states of high blood fat and high 
blood viscosity can be improved, and the 
blood circulation of the brain can be promoted, so that the memory is improved.
