Evening primrose oil is extracted from the seeds of Oenothera biennis, a plant native to North and South America. It gets its name from its yellow blossoms, which bloom in the evening.1 The oil contains linoleic acid, gamma-linolenic acid (GLA), and other omega-6 fatty acids.2
Evening primrose oil has been studied to treat conditions related to inflammation, pain, and menopause. This article explores the available research on evening primrose oil, what it's commonly taken for, and its potential side effects. You'll also learn about common dosages and how to store products safely.
Even though it is commonly used as a natural medicine, current research does not support evening primrose oil as a treatment for any medical condition.
Evening primrose oil has been studied to treat conditions related to menstruation and menopause. These conditions include cyclical breast pain, premenstrual syndrome, hot flashes, and osteoporosis.
It has also been studied to treat skin and inflammatory conditions. This section provides an overview of studies for these conditions.
The way evening primrose oil works is not completely understood yet. Scientists have suggested it has to do with chemical components in the oil extracted from the seeds. Many potential benefits are attributed to GLA, an omega-6 fatty acid.1
The evidence for evening primrose oil as a treatment is supported by small, preliminary studies and reviews of those studies. Some of these studies were done in GLA itself rather than evening primrose oil. The research is limited, and conclusions about its effects can't be drawn yet.
