Research on Evening Primrose

With an oil Evening primrose oral intake, neuropathy, atherosclerosis and diabetic retinopathy were preventively treated diabetic rats. The treatment of multiple sclerosis is also being studied, with encouraging results.

Evening primrose oil is known for its beneficial effects on eczema and premenstrual syndrome. New research shows other preventive and curative arthritis, the prevention of cardiovascular risk and kidney stones.

Evening primrose oil is rich in vitamin E and is very useful as it is also one of the most rich in gamma-linolenic acid (GLA), an essential fatty acid that is one of the omega-6 fatty acids (vitamin F ).

The role of evening primrose oil can be explained by the fact that its fatty acid (GLA) is converted in the body into prostaglandins (PGE 1) which have a moisturizing and anti-inflammatory. They lower blood pressure, promoting blood flow and decrease the risk of thrombosis, decreasing cholesterol synthesis and protect the liver. They also boost immunity by acting on the cells.

Other roles that are attributed to evening primrose oil can be explained in part by PGE1 but perhaps also by other constituents of this oil: regulating the menstrual cycle, decreased prolactin and therefore syndromes PMS , increased secretion of mucous membranes, eyes and saliva.

New research shows the many preventive and curative virtues of evening primrose oil.

What we already know:

Eczema and dry skin

By its hydrating, this oil helps in some way to restore the protective lipid film. The action focuses on the enzymes involved in the integration of essential fatty acids in the skin. Meanwhile, evening primrose can limit inflammation. Because unlike borage oil which can aggravate inflammation, evening primrose blocks irritative phenomena.

Mastitis and premenstrual syndrome

It reduces the pituitary prolactin. A hormone linked to stress, arousal, and increases in women before menstruation. In this indication, evening primrose oil can be taken at a dose of 2 capsules, from the 10th to 28th day of the cycle. More recent studies have reported the value of combining organic evening primrose oil and natural vitamin E, the latter also affecting morale.

New Discoveries:

Arthritis and Rheumatoid Arthritis

The supply of the large amount of fatty acid (GLA) which is found in evening primrose oil may help to reduce the symptoms of arthritis. For this the dose must be high (about 5 grams, or 10 capsules per day). This effect seems to be comparable to that of krill oil and it is possible to combine the two oils.

Prevention of cardiovascular risk and antiplatelet effect

Regular courses of evening primrose oil would be interesting bio humans as much as women. A recent study reports the metabolic activity. Indeed it would participate in the fight against platelet aggregation as well as aspirin, by thinning the blood. It is certainly a bit less effective than krill oil. It is possible again to combine the two oils alternately in cardiovascular prevention.

Prevention of kidney stones

A study published in December 2009 showed that taking 500 mg was sufficient to reduce the presence of calcium and urinary oxalate in the first week. The authors advise evening primrose oil as a preventive of oxalate kidney stones.

Zoom in on the gamma-linolenic acid: Gamma-linolenic acid is naturally synthesized by our body from linoleic acid fatty acid. This fatty acid is essential for immunity, anti-infectious and anti-allergic defenses. Moreover, it plays an important role in the hydration and elasticity of the skin.
Unfortunately, in many cases, transformation of linoleic acid into gamma linolenic acid is weakened. It is important then to bring it directly from the outside. Only a few vegetable oils contain gamma-linolenic acid in these proportions: borage oil, evening primrose are the best known. Expose omega 6: omega-6 essential fatty acids are classified because the body human can produce. External input is essential. The omega-6 linoleic represented by entering ceramides acid composition.
