No Benefit of Evening Primrose Oil for Treating Eczema, Review Suggests

Apr. 29, 2013 — Research into the complementary therapies evening primrose oil and borage oil shows little, if any, benefit for people with eczema compared with placebo, according to a new systematic review. The authors, who published their review in The Cochrane Library, conclude that further studies on the therapies would be difficult to justify.

Atopic eczema, also known as atopic dermatitis, is an itchy skin condition with no known cure. Usually emerging in childhood, it affects about 10 to 20% of school age children, who may suffer with tight, red, painful skin, sleepless nights and low self-esteem due to appearance, itching and scratching. For around 60% of people, the disorder will improve or clear up by adulthood. Creams, ointments, bath additives, topical steroids and antihistamines are some of the treatments prescribed to ease the condition. However, people often turn to complementary therapies such as evening primrose oil and borage oil in the belief that they will avoid side effects of conventional eczema treatments. Both evening primrose oil and borage oil contain high quantities of gamma linoleic acid, which was once thought to play a role in reducing skin inflammation in eczema.

The researchers analysed the benefits and side effects associated with evening primrose oil and borage oil in 27 studies involving a total of 1,596 people (adults and children) in 27 countries. Participants took evening primrose oil or borage oil, or a placebo, for between 3-24 weeks. Overall, the researchers found that taking evening primrose or borage oil offered no clear improvement of eczema symptoms over placebos. Commonly used placebos included olive oil and paraffin oil. There was also no improvement in quality of life with the complementary therapies, although only two studies considered this measure.
