Evening primrose oil is one of the most popular and perhaps most effective of the omega-6 essential fatty acids. It comes from the evening primrose (Oenothera), a lovely yellow flower that grows wild along roadsides. The seeds contain large amounts of GLA (gamma-linoleic acid), a linoleic acid metabolite. Unlike other omega-6 fatty acids, GLA does not lead to increased production of pro-inflammatory cytokines, but has an anti-inflammatory effect. Evening primrose oil has been used to help alleviate the symptoms of premenstrual syndrome (PMS), menstrual cramps, and arthritis, often with dramatic results. It may even lessen the symptoms of endometriosis.

USES IN ME/CFS: Patients with CFS/ME have reported increased energy, improvements in skin disorders (eczema, acne, dry skin), and decreased mood swings. Side effects, although uncommon, include headache, nausea, mild intestinal discomfort, and, rarely, weight gain.
