Starflower

Starflower, also known as borage (Borago officinalis), is a hardy annual herb native to the Mediterranean but widely cultivated in the UK and Europe. Traditionally, starflower has been used in herbal medicine for its soothing and anti-inflammatory properties, with its leaves and flowers appearing in teas, salads, and as garnishes. In modern health practices, starflower is prized for its seed oil, which is the richest natural source of gamma-linolenic acid (GLA), an omega-6 fatty acid linked to hormonal balance, skin health, and inflammation control. Research highlights its potential in supporting women’s health, particularly for premenstrual syndrome (PMS), menopause, and inflammatory conditions such as eczema and rheumatoid arthritis. The oil’s active compounds interact with the body by influencing prostaglandin production, which helps regulate immune responses, inflammation, and hormonal fluctuations.

Key Facts

• GLA from starflower oil supports the production of prostaglandins, hormone-like substances that regulate inflammation and immune function
• Supplementation may help alleviate symptoms of PMS, menopause, and certain skin conditions like eczema and dermatitis
• Clinical studies suggest starflower oil can reduce joint tenderness and inflammation in rheumatoid arthritis
• The oil is often used to promote skin hydration, repair, and barrier function, making it popular in skincare products
• Starflower oil may also support heart health by improving blood circulation and helping to regulate blood pressure

What does the research say about starflower and its effects on the body?

Research indicates that starflower oil’s high GLA content plays a significant role in reducing inflammation and supporting hormonal balance. Clinical trials have shown improvements in PMS symptoms, reductions in joint pain for rheumatoid arthritis sufferers, and benefits for inflammatory skin conditions. While more large-scale studies are needed, current evidence supports its use for these targeted health concerns.

How is starflower traditionally used?

Traditionally, starflower leaves and flowers were used in teas, salads, and as herbal remedies for ailments like coughs, melancholy, and to encourage lactation. The oil, pressed from the seeds, has become the primary form for supplementation due to its concentrated GLA content and associated health benefits.

How to consume or apply starflower?

Starflower oil is most commonly taken as a dietary supplement in capsule form, with typical dosages ranging from 1,000 mg per day, providing around 200 mg of GLA. The oil can also be used topically in creams or serums for skin health, or the fresh flowers and leaves can be added to salads and soups for culinary use.

Are there any known side effects or precautions when using starflower?

Starflower oil is generally well tolerated, but some people may experience mild digestive upset, headaches, or skin rashes. It should be avoided by those taking anticonvulsant medication, people with liver issues, and during pregnancy or breastfeeding unless advised by a healthcare professional. Always ensure the oil is certified free from harmful pyrrolizidine alkaloids, as these can be toxic to the liver.

How long does it take to see the benefits of starflower?

Benefits such as reduced PMS symptoms or improved skin hydration may become noticeable within a few weeks to three months of regular supplementation, depending on the individual and the condition being addressed. For chronic inflammatory issues like rheumatoid arthritis, studies often observe results after three to six months of consistent use.

What to look for when purchasing starflower products?

Choose supplements that specify the amount of GLA per capsule, as this is the key active ingredient. Ensure the oil is cold-pressed and certified free from pyrrolizidine alkaloids for safety. Opt for reputable brands with clear labelling and, if possible, independent quality testing.

Is starflower oil better than evening primrose oil?

Starflower oil contains nearly double the amount of GLA compared to evening primrose oil, making it a more potent source for those seeking the benefits of this fatty acid. As a result, fewer capsules may be needed to achieve the desired effect, and it is often preferred for women’s health and inflammatory conditions.

Can starflower oil help with weight management?

Emerging research suggests that GLA from starflower oil may help regulate appetite hormones and reduce the likelihood of regaining weight after weight loss. While the evidence is not yet conclusive, it is thought that improved hormone balance plays a role in these effects.

Does starflower oil support heart health?

Starflower oil’s anti-inflammatory properties and essential fatty acids may contribute to better heart health by supporting blood circulation and helping to regulate blood pressure. Regular intake as part of a balanced diet may offer protective benefits, though it should not replace prescribed heart medications or medical advice.
