Evening Primrose as a Carrier Oil

Evening primrose (Oenothera biennis) is a member of the Onagraceae plant family. Although it is not as common as some carrier oils, such as apricot kernel (Prunus armeniaca) or jojoba (Simmondsia chinensis), evening primrose oil has uses in aromatherapy as a carrier oil. Here’s a short introduction to evening primrose oil.

Botanical Profile of Evening Primrose

Evening primrose is indigenous to North America, although it was naturalized in the Mediterranean region when it was brought to Europe in 1619. Evening primrose is a versatile plant which is found growing in the desert, by the ocean, in mountain landscapes and by the river. It has yellow flowers which bloom and die within the same evening (hence its name, evening primrose), a pattern which is repeated the following evening. Evening primrose oil is extracted from the pod seeds which form when the flowers die.

Historic Use of Evening Primrose

Native American Indians used the seeds, roots and leaves of evening primrose to make various medicinal infusions, one of which was used to treat wounds. The Europeans did not commonly use evening primrose for medicinal purposes but in his book, Carrier Oils for Aromatherapy and Massage, Len Price cites that the English herbalist, John Parkinson (1567 – 1650), described the use of evening primrose in 1629.1

Chemical Components of Evening Primrose Oil

Evening primrose oil contains up to 25% essential fatty acids, such as gamma-linolenic acid (GLA) and linoleic acid (LA), making it highly unsaturated, unstable, and reactive. It is similar to borage oil, although borage oil contains a much higher percentage of GLA than evening primrose oil.

Use of Evening Primrose Oil in Aromatherapy

Externally, evening primrose oil is used in aromatherapy to treat the following conditions:

  • dry, itchy skin

  • dandruff

  • eczema

  • healing wounds

  • psoriasis

  • dermatitis

  • scars

  • anti-wrinkle cosmetic lotions.

Scientific Evidence for Use of Evening Primrose

Evening primrose oil is recommended for many problems associated with women, such as menopausal symptoms, P.M.S., breast pain, breast cancer and pregnancy related problems.2 Note that some of these recommendations are for use in capsule form for internal use and may not hold any real validation. However, evening primrose oil is often supported for use in the treatment of eczema.3 Len Price, in his book Carrier Oils for Aromatherapy and Massage, cites two studies which support the use of evening primrose oil, one for eczema (Kerscher and Korting 1992) and one for psoriasis (Ferrando 1986).1

Cautions for Using Evening Primrose Oil

Most cautions associated with using evening primrose oil are for internal use; as evening primrose oil contains a high level of GLA, prolonged use of internal supplements is not recommended. Some side effects of the internal use of evening primrose oil include headache and upset stomach.

Medical opinion should be taken for possible interaction with other prescription and non-prescription drugs, in addition to conditions such as epilepsy and high blood pressure. However, in general, the external use of evening primrose oil for aromatherapy, will not cause a reaction in most people.
