Native to North and South America, evening primrose has become firmly established in Europe.

Evening primrose – what is worth knowing about it?

Native to the North American continent, evening primrose (Oenothera) is a genus of herbaceous plants with large, characteristically yellow flowers. Evening primrose has traditionally been used by Native Americans in the form of an infusion, made from all the above-ground parts of the plant. Traditional evening primrose infusions were used to treat wounds and skin conditions and to alleviate unpleasant respiratory symptoms, such as asthma.

Evening primrose and the oil derived from it only reached Europe by chance in the 18th century. In fact, the seeds of this plant became stowaways in the ballast of a ship. Since then, evening primrose has been found in many European countries. In Poland alone, there are over a dozen species of evening primrose, the most common of which is the biennial evening primrose (Oenothera biennis). As its common name suggests, this evening primrose lives for two years – in the first year it produces roots, stems and leaves, and in the second, flowers and fruit.

Its nutritional richness, which is both remarkable and intriguing, attracts the curiosity of the scientific world. Evening primrose oil is currently being studied for all its alleged and proven health benefits.

The oil itself is extracted from tiny dried seeds. It is characterised by a pale yellow hue, and a sweet, pleasant aroma. To preserve all the nutrients contained in the plant, this oil is generally extracted by cold pressing. Oil extracted from evening primrose seeds contains a high concentration of gamma-linolenic acid (GLA), an Omega-6 fatty acid, known for its anti-inflammatory and skin-conditioning properties.

Benefits – what does evening primrose oil help with?

Evening primrose oil has traditionally been used to treat various conditions related to the functioning of the endocrine system, as well as general health. The traditional use of the oil, and the confirmation of its benefits through advances in modern medicine have shown, that the oil can be of significant help, for example, in:

  • Preventing hypercholesterolaemia and cardiovascular disorders – the oil is rich in unsaturated fatty acids and phytosterols. These remarkable compounds are known for their cholesterol-lowering and cardioprotective effects, which help reduce the development of atherosclerosis. In this sense, the use of evening primrose oil contributes to the prevention of cardiovascular disorders and the high cholesterol levels that often accompany them.
  • Reduction of inflammation – one of the oil’s distinctive features is its high content of gamma-linolenic acid. This specific fatty acid is involved in the production of type 1 prostaglandins. These hormones regulate the body’s inflammatory response. As a result, evening primrose oil, at least partially, inhibits the mechanisms responsible for inflammation, including swelling, pain and redness.
  • Aid in weight loss – evening primrose oil is not fattening,; what is more,, it is even an effective ally in weight loss. This is because, it contains the aforementioned gamma-linolenic acid, a vegetable oil, that is easily and quickly absorbed by the body. It thus regulates appetite, by having a strongly satiating effect. For this reason, this Omega-6 fatty acid prevents the accumulation of fat and aids its elimination, facilitating weight loss. Relief from hormonal disorders – The gamma-linolenic acid contained in evening primrose oil participates in the production of prostaglandins, and hormones, which influence hormonal balance, and, in particular, the production of progesterone. The use of evening primrose oil may help alleviate symptoms associated with hormonal changes in the menstrual cycle, and also reduce the adverse symptoms of the menopause.
  • Prevention of osteoporosis – osteoporosis mainly affects women after the menopause. Studies conducted in the 1990s showed, that supplementation with evening primrose oil, combined with fish oils and calcium, can improve overall bone density.

The benefits of regular use of evening primrose oil do not end there. The components in the oil also help reduce inflammation in blood vessels and maintain proper blood circulation. Furthermore, evening primrose oil may help lower blood pressure and regulate blood lipid levels, which promotes better cardiovascular health. These benefits make evening primrose oil a natural option to complement the treatment of conditions such as high blood pressure and cardiovascular disease.

Evening primrose oil for facial skin and skin problems – is it an effective treatment?

Cold-pressed evening primrose oil has been used for centuries to protect and soothe sensitive, dry or mature skin. The fatty acids present in this oil give it powerful moisturising properties. They rebuild the lipid barrier, which protects the facial skin from external factors. Furthermore, it is rich in vitamin E and triterpenic acids, known for their antioxidant properties, particularly in reducing the appearance of wrinkles and fine lines that make the skin look older. It is precisely because of this property that evening primrose oil is widely used in cosmetics, mainly in the form of creams.

Furthermore,, evening primrose oil is also a helpful ally in the treatment of unsightly acne, which, being a source of many insecurities, is considered a condition with both hormonal, and inflammatory causes. Due to its ability to promote hormonal balance and reduce inflammation, the oil results in a visible reduction in the number of acne lesions on the skin and their severity.

Evening primrose oil during pregnancy – how does it affect pregnancy and fertility?

Evening primrose oil has been studied for many years for its potential effectiveness in promoting fertility in women. Some preliminary studies suggest, that evening primrose oil may help reduce the size and recurrence of ovarian cysts, affecting women’s overall fertility. It has also been observed that evening primrose oil may have a significant positive effect on improving egg quality, regulating the menstrual cycle and increasing the chances of pregnancy. It is believed that this is due to the oil’s ability to balance hormone levels and improve the body’s overall hormonal function. The oil is also extremely popular among pregnant women, particularly after 36 weeks. By influencing blood pressure and reducing inflammation, it improves blood flow to the uterus, supplying nutrients that support both the woman’s body and the unborn child.

Cold-pressed evening primrose oil for drinking – is this dietary supplement effective?

One way to take the oil internally is by drinking it. This method is just as effective a form of treatment as capsules. If you decide to take evening primrose oil in liquid form, the recommended daily dose is one tablespoon, which is approximately 15 ml of oil. The ingredients it contains first reach the stomach and intestines, and then enter the bloodstream, regulating the functioning of the entire body.

When taking evening primrose oil, you should choose a fixed time of day, and remember to take the supplement regularly. The whole process should be repeated every day, until the first visible effects appear. The oil can be added to food as a dressing or as a drink.

Evening primrose oil in tablet form – how to use it?

Although it may help, when used externally, it is the internal intake of evening primrose oil that allows it to reach its full potential. To make taking the oil easier, it is best to use it in the form of dietary supplements, such as tablets and capsules. The beneficial effects of evening primrose oil are generally felt after a few months of use, by which time the body has become accustomed to its constant presence.
