Evening Primrose is an excellent carrier oil and is one of the richest sources of essential fatty acids.
Cold pressed Evening Primrose Oil has a golden yellow colour and fresh nutty odour. It is obtained by expeller pressing of the tiny black seeds. As the seeds contain only around 25% oil and they are fairly expensive, Evening Primrose oil is often obtained by solvent extraction as this method has a much higher oil yield. Recently, Evening Primrose Oil has received a great deal of attention because it contains the rare EFA g-linoleic acid, which is found in only three other plant species.
