Botanical Name - Linum usitatissimum Category - Medicinal Form - Dry Part Used - Seeds General Information - Linum usitatissimum (Linn.), commonly known as flaxseed or linseed, belongs to the family Linaceae. The flax plant is not a new crop and is native to West Asia and the Mediterranean coastal lands, Asia Minor, Egypt, Algeria, Tunis, Spain, Italy, and Greece; in all these areas, only fiber flax is cultivated. In south-west Asia, including Turkestan, Afghanistan, and India, only oil types are grown. In North America, flaxseed is the preferred term for flax used for human consumption, whereas Europeans use the term linseed for edible flax. Historical records indicate that flaxseed dates back to around 9000â??8000 BC in Turkey, Iran, Jordan, and Syria. Flaxseed is grown in approximately 50 countries, most of which are in the Northern hemisphere. In 2002, Canada was the largest producer of flaxseed, accounting for approximately 33% of the 2 million metric tons produced, followed by China (20%), United States (16%) and India (11%). Phytochemicals - Flaxseed is well-known for the content of chemical compounds with specific biological activity and functional properties: polyunsaturated fatty acids (PUFA) omega-3 family, soluble dietary fibers, lignans, proteins and carbohydrates. However, it is constituted by few levels of adverse health compounds such as Cadmium, protease inhibitors and cyanogenic compounds. Flaxseed is emerging as an important functional food ingredient because provides oil rich in omega-3, digestible proteins, and lignans. In addition to being one of the richest sources of �±-linolenic acid oil and lignans, flaxseed is an essential source of high quality protein and soluble fiber and has considerable potential as a source of phenolic compounds. Flaxseed has nutritional and functional properties. In fact the content of compounds such as polyunsaturated fatty acids, essential amino acids, vitamin E, lignans and dietary fibers makes flaxseed a source to satisfy basic needs in the human diet and health maintenance. Healthy properties are related to anti-inflammatory, anti-oxidant, anti-carcinogenic activities and to the lowering of cholesterol, the decrease of cardiovascular disease and the prevention of diabetes.
