Evening primrose oil (EPO) is made from the seeds and the flowers of the evening primrose plant via cold pressing. Evening primrose seeds are rich in omega 6 essential fatty acids (EFAs), including linoleic acid and gamma-linolenic acid (GLA). The human body is unable to produce GLA, so we need to consume enough GLA in our diet or help get GLA through
supplementation. The therapeutic effects of EPO are attributed to the direct effect of its essential fatty acids on immune cells as well as their indirect effect on the synthesis of eicosanoids (such as prostaglandins, cytokines, cytokine mediators).
