Evening primrose oil, (Oenothera biennis L.), is extracted from the seeds of the evening primrose plant, a perennial with yellow flowers commonly found in North and South America. Other names for the plant are tree primrose and sundrop. The oil extracted from the plant seeds is often put into capsules for internal medicinal use.
The flowers of the plant only open in the evening time, hence the name "evening primrose", and are yellow in most species but can be also white, purple, pink or red, there are four petals that make up the flower.
Evening primrose has been used as food and medicine throughout history, often for respiratory infections and upset stomachs. Young roots can be eaten like a vgetable and the shoots can be eaten as a salad. Native Americans ate the boiled, nutty peppery flavored root, and also used leaf poultices from the plant for bruises and hemorrhoids.
Evening primrose oil (EPO) is considered a useful dietary supplement because it is a good source of essential fatty acids. EPO contains an omega 6 essential fatty acid, gamma-linolenic acid (GLA), which is believed to be the active ingredient. The Oil is a natural, and one of the richest, sources of Gamma-Linolenic acid as it contains about 72% Linoleic acid and 9 percent GLA.
EPO has been studied in a wide variety of disorders, particularly those affected by metabolic products of essential fatty acids. Evening primrose oil is highly valuable to those who cannot otherwise form enough GLA. This would include those who do not get enough essential fatty acids in their diet, drink, have low thyroid function, or have received radiation treatment.
Preliminary studies are showing Evening Primrose Oil to be an anti-oxidant in that it also counter acts the formation of free radicals. Free radicals are most often associated with the aging process.
