Hemp oil is about as good as flax seed oil
Some say it is even better (see below)
What are the benefits of hemp seed oil over flax oil? The (3:1) ratio of the Essential Fatty Acids, three parts linoleic acid (Omega 6) to one part alpha-linolenic acid (Omega 3) in hemp seed oil is favorable for the human diet because it matches the nutritional requirements of our bodies. Too much of one will cause a deficiency of the other. Flax oil, despite its higher Omega 3 content, has a less favorable ratio (1:5). Long-term exclusive use of flax oil can lead to a deficiency of Omega 6, producing symptoms like dry skin, papery skin and joint pain.Unlike hemp oil, flax oil does not contain Gamma-Linolenic Acid (GLA), a derivative of Omega 6, and an important triple- unsaturated fatty acid vital for human metabolism. Hemp Oil may be successful in the treatment of eczema, pre-menstrual tension and arthritis.
