It involved sixty women aged between fourteen to fifty years of age. They suffered with bad PMS episodes, and failed to get relief from standard treatments.

They took 500 mg capsules per day, starting from three days.

Two 500-mg capsules daily, starting three days before expected beginning of the symptoms until the beginning of menstruation.

Sixty two percent of the women had total relief from PMS symptoms. Twenty-two percent had partial relief. Slight or no change at all was seen sixteen percent.

Brush said, "Excellent results were obtained with evening primrose oil for premenstrual breast discomfort, including some severe cases of fibrocystic breast disease."

A controlled, double blind, crossover study, employed different amounts of EPO on ninety-nine atopic eczema patients. The study revealed major improvements with high doses as well as no side effects.
