A pretty yellow flower that is native to North America, evening primrose is, as you would expect, similar looking to the British primrose which grows wild in many parts of the countryside here. They are not directly related, however. The name ‘primrose’ comes from the Latin prima rosa, meaning first rose of the year. The oil is made from the seeds of the plant and it’s this oil that’s used as a treatment.
What is evening primrose oil used for?
Although you may be primarily aware of the oil and its purported benefits for symptoms of menopause, it is also used for skin disorders such as eczema, psoriasis, bruises, and dry, itchy, thickend skin. It’s also touted as a treatment for hair loss.
What’s the history of evening primrose oil?
Evening primrose oil has been used worldwide for centuries, with Native Americans initially using various parts of the plant – to treat wounds and bruises, sore throats, indigestion and so on. Since then it has been used elswhere too, to treat high blood pressure, hair loss, and hormonal problems.
What’s the best way to take evening primrose oil?
As it is absorbed by the skin evening primrose oil can be ingested or applied to the skin. It is possible to ‘over-dose’ on it, meaning that high doses can cause side effects (see below for more on that). Look for supplements containing between 500 and 1000mg per capsule. Studies using the oil have ranged from participants taking 1500mg per day to up to 6000mg per day. But it is advisable to start at a lower dose and build up. Cold-pressed oils retain more of the beneficial substances in an oil so ideally choose a product prepared in this way too.
The recommended dose of evening primrose oil is 8 to 12 capsules a day, at a dose of 500 milligrams per capsule. A range of evening primrose oil products are available for purchase online.
To moisturise skin or hair, you’ll want to use oil – or a product containing the oil – directly on your skin/hair. The oil contains omega-6 and 9 oils which work as anti-inflammatories and soothe the skin, supporting the growth of new skin and hair.
Does evening primrose oil really work?
Research shows that evening primrose oil has an effect on prostaglandins, hormones that are linked to your inflammatory response and circulation, helping blood clot among other actions.
One clinical trial, published in the Archives of Gynecology and Obstretics, found evening primrose oil reduced the severity of hot flushes, the frequency and duration, when compared to a placebo. The study participants took the evening primrose oil for six weeks. There are, however, other clinical studies that couldn’t show a significant improvement on symptoms of menopause.
Other research, on rats, suggests that it may show benefits as an anti-inflammatory and in reducing blood cholesterol.
