Evening primrose oil (EPO) is the oil extracted from the seeds of the yellow evening primrose wildflower. It is a rich source of linoleic acid and gamma-linoleic acid (GLA), both omega-6 essential fatty acids. GLA is used to make hormone-like substances called prostaglandins, which can help calm inflammation. Many women use evening primrose oil (EPO) to manage symptoms of pre-menstrual syndrome (PMS) and menopause, such as hot flushes. EPO is also used to help ease skin conditions including eczema and acne.
Evening primrose oil has been promoted as an effective treatment for a variety of ailments, including eczema and breast pain, since the 1930s.2 Many of these benefits are attributed to GLA, a fatty acid found in soybeans, walnuts, seeds, and vegetable oils (like rapeseed, canola, and linseed oil). Some the claims are better supported by research than others.
Some evening primorse oil uses are:
- Menstrual Conditions
- Rheumatoid Arthritis
- Diabetic Neuropathy
