Evening primrose oil

Function and sources
The seed oil from this powerfully scented plant is the only known source of both linoleic acid (LA) and gamma linolenic acid (GLA), with the exception of mother's milk. It is also the largest source of GLA of any food. Not surprisingly, evening primrose combines many of the effects of both LA and GLA.

Evening primrose oil has been used in the following conditions:

  • Cirrhosis of the liver
  • Depression
  • Deregulation of blood calcium
  • Disruption of nerve impulse transmission
  • Eczema
  • Elevated blood cholesterol levels
  • High blood pressure
  • Imbalance of prostanglandin production
  • Increased blood clotting
  • Inflammation
  • Premenstrual syndrome
  • Reduction of insulin production in diabetic cases
  • Weakening of the immune system

Women suffering from estrogen-related breast cancer and epileptics should avoid using evening primrose oil. Substitutes such as black currant oil may be used instead, but consult an experienced health professional before doing so.
