Cannabis sativa seed flour is a common constituent of the recipes of Ænduro, Ingenio, Praevens and Longevis. Such flour contains about 30% oil, which has a high content of total polyunsaturated fatty acids (PUFA) (>70%) and alpha-linolenic acid (ALA) (11%-20%). The oil has a high unsaturated/saturated fatty acid ratio and an almost perfect balance of omega-3 and omega-6 fatty acids, as required for healthy foods and such optimal balance of omega-3 and omega-6 polyunsaturated fatty acids supports memory in cognitively intact elderly people. In addition, diets rich in polyunsaturated fatty acids help maintain healthy central and peripheral metabolism, brain plasticity, memory and learning, blood flow and neural cell genesis. A double-blind prospective study of patients diagnosed with chronic headaches found that polyunsaturated omega-3 fatty acids are useful for prophylaxis of headache attacks. In patients with atopic dermatitis, the use of edible hemp oil caused significant changes in the fatty acid profile in plasma, increasing levels of essential fatty acids, linoleic acid and alpha-linolenic acid, and improving clinical symptoms of atopic dermatitis.
