Evening primrose has also been used to treat asthma, eczema, attention deficit- hyperactivity disorder (ADHD), hepatitis B, high cholesterol, liver cancer, breast pain, obesity, menopausal hot flashes and night sweats, premenstrual syndrome (PMS), and skin or joint symptoms of psoriasis. However, research has shown that evening primrose may not be effective in treating these conditions.
