The evening primrose is an annual or biennial, rustic (-30° C), which can be found naturally along paths near the Atlantic and Mediterranean coasts but also on the embankments of railways. Its erect stems are lined with large rosettes of downy leaves veined with red, measuring between 10 and 30 cm long, oblong, lanceolate, toothed, a little sticky.
Throughout the summer, yellow flowers in section, 3 to 5 cm in diameter, appear in clusters along the ears: they have 4 sepals, 4 petals and 4 stigmas forming the pistil; they bloom in the evening and exhale a pleasant sweet scent, until noon. Moreover, we also call the evening primrose "evening primrose" or "beautiful night".
It is its seeds that are prized to extract an oil with recognized antioxidant benefits, because of the unsaturated fatty acids it contains: oleic acid, linoleic and especially gamma-linoleic acid (Omega-6) which would give good results against diabetes, cholesterol, atherosclerosis, arthritis and premenstrual pain.
Otherwise, it is more famous in dermatology for its benefits against eczema. Many cosmetic products use it to prevent the appearance of wrinkles and preserve the elasticity of the skin.
