23rd November, 2021 • 4 min read

Overview

The oil of the evening primrose plant is a rich source of fatty acids. These are considered to be essential for body health - and so are often called essential fatty acids. Evening primrose oil is used by a lot of women around the world for several health conditions, including breast pain (mastalgia) and menopausal and premenstrual symptoms. However, there’s relatively little evidence to support the effectiveness of evening primrose oil as a treatment.

In this article we look at the evidence for the use of evening primrose oil for menopause, symptoms it might help and possible side effects.

What are the possible benefits of evening primrose oil for menopause?

Evening primrose oil is often taken to help to treat the
