Evening Primrose Oil (EPO) is made from the seeds of the plant Oenothera biennis (related actually to willow, not primrose). It is a rich source of gamma-linolenic acid (GLA) and linoleic acid (LA) — two omega-6 fatty acids from which the body makes prostaglandins. Prostaglandins are hormone-like chemicals that regulate many bodily processes, including inflammation. The body’s ability to make gamma-linolenic acid declines with age.

Scientific studies have provided evidence that supplementary evening primrose oil and its components can:

  • decrease incidence of cardiovascular disease (3 g/day GLA)
  • lower blood pressure
  • improve blood cholesterol profile (3.6 g/day GLA)
  • inhibit development of atherosclerosis
  • ameliorate acute respiratory distress syndrome
  • reduce symptoms of rheumatoid arthritis (2.8 g/day GLA)
  • improve nerve function in diabetics
  • ameliorate chronic fatigue syndrome
  • reduce migraine attacks
  • reduce appetite for fats in overweight people
  • prevent abnormalities in red blood cell membranes caused by hemodialysis
  • reverse bone loss from osteoporosis
  • enhance tamoxifen’s ability to suppress breast cancer (2.8 g/day GLA)
  • ameliorate psoriasis
  • improve symptoms of atopic dermatitis (274 mg GLA twice a day)
  • improve skin problems caused by hemodialysis (2 g/day GLA)
  • ameliorate premenstrual syndrome
  • prevent cyclic breast pain
  • enhance immunity
  • ameliorate dry eye syndrome (15 mg/day GLA + 28 mg/day LA)
