Why evening primrose oil is good for you
Evening primrose is a flowering plant that grows in the wild in Europe and North America, whose yellow flowers only open up at sunset.
The whole plant (including the flowers) as well as the root have been used for centuries for medicinal purposes.
The most potent part of the plant is the oil in the seeds of the flowers, which contains gamma-linolenic acid (GLA). GLA is an essential fatty acid that the body converts into prostaglandins, which are hormone-like substances that have many metabolic functions in the body. The GLA in evening primrose oil, when converted into prostaglandins acts as an anti-inflammatory.
GLA is also found in mother's milk, some types of fish and spirulina. It is also found in borage seed oil and black currant seed oil, which actually have higher levels of GLA than evening primrose oil.

- Diabetic neuropathy - one study showed significant reduction in pain, prevention of nerve damage, resulting in numbness and tingling and better blood flow in the extremities
