There are still many reasons for premenstrual syndrome, among which the most common is the lack of the first prostaglandin PGE1, which is related to the high prolactin (Prolactin), and the GLA (γ- Linolenic acid) was found to increase PGE1 and inhibit Prolactin, so it is believed to improve PMS.The effect of evening primrose oil on improving PMS can be said to be both positive and negative. Early studies are biased in favor, while recent studies have confirmed that the effect is no better than placebo, or only slightly improved.

Older people (especially post-menopausal women) are the most common people suffering from dry eye syndrome. Other factors, such as wearing contact lenses, drug use, and excessive viewing of computers and mobile phones, may further trigger or aggravate dry eye symptoms.
A double-blind controlled study (6 months in 76 patients with contact lens-related dry eye syndrome) found that taking evening primrose oil improved overall contact lens comfort (contactlenscomfort, by 20%), and reduced dry eye evaluation scores (by 40%).
The underlying mechanism is related to the increased tear production (measured by tearmeniscus height) and anti-inflammatory effects of evening primrose oil, but due to the small number of samples, more studies are needed to further confirm.
