Originally from the Middle East and widespread throughout the Mediterranean basin where its cultures date back to Babylon in 3000 BC, flax (Linum usitatissimum), an annual herbaceous plant, with large sky-blue flowers, was already known not only for its fabrics obtained from its fibers but also for the known beneficial properties of its seeds from which an oil is extracted, by cold pressing, for both food and cosmetic use.
Originally from the Middle East, linen arrived in Europe on the ships of the Phoenician merchants and spread almost everywhere: appreciated for its resistance to bad weather; from its dried stems and then put to macerate in water, a textile fiber is obtained that was once reserved only for the noble and powerful
Oil is obtained from its seeds; one of the major concentrated sources of essential omega 3 polyunsaturated fatty acids (alpha-linoleic acid) which is then converted into the active forms EPA and DHA which we know are essential for well-being with an anti-inflammatory action, for maintaining cardiovascular health and protection and for the brain against aging. It also contains omega 6 (linoleic acid) important fatty acids (if taken in the due physiological proportions) because, being among the components of cell membranes, they are necessary for the correct functionality of the tissues, to optimize the inflammatory response by the body, with the formation of prostaglandins and leukotrienes (pro-inflammatory action) and are essential for both growth and brain development.
Contains monounsaturated oleic acid as omega 9; non-essential fatty acids with important protective characteristics on the cardiovascular system at the level of LDL cholesterol and blood pressure.
In addition, there is also a component of saturated fat such as stearic and palmitic acid.
The antioxidant activity of the oil obtained from flax seeds is favored by the content of Vitamin E (17.5 mg per 100 g) Vitamin C, Vitamins B, with a good presence of lecithin; phospholipid necessary for the proper functioning of the nervous system and brain, lignans (phenolic antioxidants) and numerous minerals such as magnesium, potassium and selenium as well as mucilage and dietary fiber.
Known in traditional medicine as a laxative, it is a good regulator of intestinal peristaltic function with good anti-inflammatory properties also useful in cases of hemorrhoids.
The benefits of linseed oil
Its most well-known and established beneficial properties on the body are related to polyunsaturated fatty acids that can affect the health and efficiency of various organic districts and systems of our body, bringing various benefits including:
Cardiovascular protection: omega 3 and 6 fatty acids, present in a balanced way, regulate the heartbeat and prevent the onset of cardio-vascular diseases.
Known are the influential properties in keeping cardiovascular parameters in balance, in particular, LDL cholesterol levels helping to dispose of triglycerides and keeping arteries clean.
Lecithin, Vitamins B and E and essential fatty acids are very important for the functioning of the nervous system: they improve focus and memory while preserving brain structures in the aging phases and in the presence of neurodegenerative diseases.
Soothing action on the gastrointestinal mucous membranes thanks to the mucilages that exert a modulating action on peristalsis.
Laxative but without attacking the intestine (as happens with common laxatives) thanks to its emollient effect on the stool.
It also acts as an antidiarrheal agent;
Antioxidant / anti-inflammatory action due to the presence of omega 3 fatty acids but also thanks to the action of lecithin and Vitamin E.
