Evening primrose is valued for its noteworthy essential fatty acid content, consisting primarily of the omega-6 EFAs linolenic acid and gamma linolenic acid. The oil is obtained by cold pressing the seeds of Evening Primrose plant, Oenothera biennis. Evening primrose is usually blended in a small (often 10%) dilution with other carrier oils.
