Evening primrose oil (Oenothera biennis) is a plant extract obtained from the seeds of the evening primrose, a plant native to North America. This oil is rich in gamma-linolenic acid (GLA), an omega-6 fatty acid whose effectiveness in treating premenstrual syndrome is recognized by the European Medicines Agency (EMA). It is a valuable oil for alleviating certain women’s discomforts and supporting skin health.
Evening primrose oil is particularly well-known for alleviating the symptoms of premenstrual syndrome. The EMA recognizes a well-established use for “the mild reduction of premenstrual syndrome symptoms.” Clinical trials report a reduction in breast tenderness, irritability, and painful periods after several cycles of regular use. The effect is generally noticeable after 2 to 3 consecutive cycles.
Beyond PMS, evening primrose oil is traditionally used to help with mild menopausal discomforts, such as hot flashes and temporary mood swings. The EMA recognizes its traditional use for “the relief of mild menopausal symptoms.” However, this benefit is based on limited data and is not a substitute for medical advice in cases of severe symptoms.
Evening primrose oil is valued for supporting skin health, particularly in people with dry, sensitive skin or skin prone to inflammation, such aseczema and psoriasis.
Evening primrose oil contains fatty acids with anti-inflammatory properties. It may help support joint comfort in cases of mildosteoarthritis or muscle tension, although scientific evidence on this point remains limited. It is not a substitute for medical treatment for chronic joint inflammation.
The dosage of evening primrose oil depends on the intended use and the form taken. It is based on the oil’s GLA and essential fatty acid content.
Evening primrose oil is well tolerated, but certain precautions are necessary, particularly during pregnancy or whilebreastfeeding.
Any severe allergic reaction, such as angioedema (facial swelling, difficulty breathing), requires immediately calling 15 or 112.
To fully benefit from evening primrose oil, select a product that meets strict quality and purity standards, thereby supportinghydration and optimal effectiveness.
