Benefits of Evening Primrose Oil – Women’s Health Supplements

 

What Is Evening Primrose Oil?

Evening primrose oil is sourced from Oenothera biennis, a plant native to North America. It contains gamma-linolenic acid (GLA), a fatty acid required by the body for growth and development.

Uses for Evening Primrose Oil

In herbal medicine, evening primrose oil is typically used to treat these health problems:

  • eczema
  • rheumatoid arthritis
  • premenstrual syndrome
  • menopausal symptoms
  • diabetes
  •  

  • Benefits of Evening Primrose Oil

    Research suggests that evening primrose oil may be of little value in the management of premenstrual syndrome or menopausal symptoms. However, other studies indicate that evening primrose oil may help with the following conditions:

    1) Eczema

    Evening primrose oil may help relieve the itching, crusting, redness, and swelling associated with atopic eczema, according to a meta-analysis published in 2006. Fatty acids are thought to play a role in these beneficial effects.

    2) Rheumatoid Arthritis

    To date, there’s little research on the effectiveness of evening primrose oil in treating rheumatoid arthritis (an inflammatory condition that causes pain and swelling of the joints). However, a report published in 2001 suggests that evening primrose oil may have indirect anti-inflammatory actions and may help manage this autoimmune disease.

    3) Breast Cancer

    Preliminary research suggests that GLA may help destroy tumors without inducing damage to normal cells or causing harmful side effects. And in a small study published in 2000, researchers found that participants who took GLA supplements in addition to the breast cancer drug tamoxifen responded more quickly to breast cancer treatment than those who took tamoxifen alone.

    How to Use Evening Primrose Oil

    Available in many health food stores and in pharmacies offering herbal supplements, evening primrose oil is typically sold in capsule form.

    If you’re considering using evening primrose oil in treatment of a chronic condition, make sure to consult your physician first. It’s especially important to seek medical guidance if you’re seeking to manage a serious condition such as breast cancer or rheumatoid arthritis.

    Evening Primrose Oil Side Effects

    Although evening primrose oil is generally considered safe, it may cause mild side effects such as gastrointestinal upset, headache, and nausea in some individuals.

    Is Evening Primrose Oil Safe?

    Intake of evening primrose oil may increase risk of bleeding for people taking anticoagulant or antiplatelet medication. It also may interfere with phenothiazines (tranquilizing drugs with antipsychotic actions).

    Since evening primrose oil may increase risk of pregnancy complications, pregnant women should consult their physician before using this supplement.
