Evening Primrose Oil (EPO)
The evening primrose plant was used for healing by North American natives long before white settlers took the continent. The European explorers learned of these healing properties from the natives. Pilgrims sent the plant back to Europe where, according to one account, it became known as the king's cure-all.
The therapeutic value of the seed oil of evening primrose is a more recent discovery. It contains 72% linoleic acid the essential fatty acid (EFA). It also contains 11% oleic acid; 6% palmitic acid; and 2% stearic acid. More importantly it is also 9% gamma-linolenic acid (GLA), which is present in only a few other seed oils.
Recent studies have shown good results for EPO particularly in reducing symptoms in premenstrual syndrome, skin problems, and arthritis, as well as for all kinds of cardiovascular disease, immunodepression, schizophrenia, Alcohol withdrawal symptoms, and depression.
