Flaxseed oil is obtained from the seeds of the flax plant (Linum usitatissimum, L.). Flaxseed oil contains both omega-3 and omega-6 fatty acids, which are needed for health. Flaxseed oil contains the essential fatty acid alpha-linolenic acid (ALA), which the body converts into eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), the omega-3 fatty acids found in fish oil. Some researchers think that flaxseed oil might have some of the same benefits as fish oil. Omega-3 fatty acids, usually from fish oil, have been shown to reduce inflammation and help prevent certain chronic diseases such as heart disease and arthritis. The present work elucidate the different pharmacological activities of Flaxseed oil, usually claimed for fish oil. However, authors also observed significant antiulcer activity of Flaxseed oil along with anti-inflammatory activity, an unusual phenomenon for anti-inflammatory drugs.
