Evening Primrose Oil

 

Background

 
  • Evening primrose is a plant native to North and South America that also grows throughout Europe and parts of Asia. It has yellow flowers that open at sunset and close during the day. The oil from evening primrose seeds contains omega-6 fatty acids, including gamma-linolenic acid (GLA).
  • Native Americans made poultices from the evening primrose plant for bruises and wounds and used its stem and leaf juices as topical remedies for skin inflammations. The leaves were taken orally for gastrointestinal complaints and sore throats. In the 17th century, evening primrose oil became a popular folk remedy in Europe, where it was known as “King’s cure-all.”
  • Today, evening primrose oil dietary supplements are promoted for atopic dermatitis (a type of eczema), rheumatoid arthritis, premenstrual syndrome (PMS), breast pain, menopause symptoms, and other conditions. Evening primrose oil may also be included in products that are applied to the skin.

 

 

 

 

 

 

Health Benefits

  • Evening primrose oil, taken orally (by mouth), has not been shown to be helpful for relieving symptoms of atopic dermatitis.
  • Studies of evening primrose oil for breast pain have not found it to be more effective than a placebo (an inactive substance).
  • There’s insufficient evidence to show whether evening primrose oil is helpful for other conditions, such as PMS and menopause symptoms.
