Onagre bisannuelle
Oenothera biennis · Common Evening Primrose
Oenothera biennis, commonly known as evening primrose, is a traditional plant with roots in various herbal practices. Its seeds and oil have been traditionally used for skin conditions and inflammation, though specific uses vary across different cultures and are not extensively documented. Scientific evidence indicates that the oil from Oenothera biennis seeds possesses strong antioxidant properties and selective antimicrobial activity against certain bacteria; however, further in vivo studies are needed to confirm these findings. The plant has also shown promise in improving cognitive performance and reducing brain inflammation and amyloid-beta plaque accumulation in 5xFAD mice models, though more research is required for broader applications. Notably, no major safety issues or drug interactions have been recorded, but the limited scientific data means that further investigation into its efficacy and potential uses is warranted.
