Is Evening Primrose Oil effective?

There is some scientific evidence that evening primrose oil can relieve breast pain. It might also help improve symptoms of rheumatoid arthritis after 6 months of treatment.

Evening primrose oil does not seem to help the symptoms of premenstrual syndrome (PMS), but it might be able to prevent PMS-related flare-ups of the symptoms of a condition called irritable bowel syndrome.

Evening primrose oil does not prevent high blood pressure due to pregnancy. It does not shorten labor, and it does not prevent babies being born after their due date.

Evening primrose oil does not relieve hot flashes due to menopause.

There isn't enough information to know if evening primrose oil is effective for the other conditions people use it for, including: acne, multiple sclerosis (MS), cancer, heart disease, high cholesterol, Alzheimer's disease, attention deficit hyperactivity disorder (ADHD), and many others.
