Evening Primrose Oil

Evening primrose oil is an oil that is derived from the seeds of the evening primrose plant. The plant is native to America and some parts of Europe and is mainly harvested for its seeds and roots which are believed to contain medicinal value. The evening primrose oil has a faint, nutty taste that many people find pleasant. However, if the evening primrose oil tastes bitter or bad, discard it as it turns rancid fairly quickly.


It is most commonly used as a dietary supplement because of its rich gamma-linolenic acid (GLA) content. About 80% of the oil is composed of GLA – an essential omega-6 fatty acid that is physiologically important for the body. GLA contains strong anti-inflammatory properties whose efficacy is on par with conventional anti-inflammatory drugs and is used to treat auto-immune diseases today.
