Borage (Borago officinalis) is an herb recognized for its nutritional composition, with its seed oil being the most concentrated source of gamma-linolenic acid (GLA). GLA is an omega-6 fatty acid and borage seed oil is considered the richest natural source, containing up to 26% of this compound. This high GLA content is a key factor in its use in supplements and skincare products.
What is Borage Oil High In?
Borage oil is primarily known for its high concentration of GLA, which the body converts into anti-inflammatory substances. This process contributes to its potential therapeutic benefits. In addition to GLA, borage oil also contains other fatty acids. Linoleic acid (LA) is present, which the body can convert to GLA, although this process can be less efficient in some individuals. Oleic acid, an omega-9 fatty acid, also contributes to the oil's properties, as do smaller amounts of palmitic and stearic acids.
What are Borage Leaves and Flowers High In?
While borage oil is prized for GLA, the fresh leaves and flowers offer a different spectrum of nutrients and are often used in cooking. These parts of the plant are notable for their vitamin and mineral content.
Key Nutrients in Borage Leaves and Flowers
- Vitamins: Borage leaves are a good source of Vitamin C, an antioxidant, and Vitamin A, important for vision and skin health. They also contain B-complex vitamins like riboflavin, thiamin, and niacin, which support metabolism.
- Minerals: Essential minerals found in borage include potassium, which helps regulate blood pressure; calcium for bone health; iron for oxygen transport; and magnesium, important for nerve and muscle function.
- Antioxidants: The leaves and flowers also contain antioxidants like rosmarinic acid.
Comparison: Borage Oil vs. Leaves and Flowers
| Nutrient Component | Borage Seed Oil | Borage Leaves and Flowers |
|---|---|---|
| Primary Nutrient | Gamma-Linolenic Acid (GLA) | Vitamins (A, C), Minerals (K, Fe, Mg) |
| Omega-6 Content | Very high (20-26% GLA) | High in other essential fatty acids, but lower GLA |
| Antioxidants | Contains antioxidants like oleic acid | Rich in a wide range of flavonoid antioxidants |
| Traditional Use | Used in supplements for inflammatory conditions | Eaten fresh in salads, brewed as tea |
| Best For | Targeting internal inflammation and skin conditions | Providing general nutritional support and culinary flavor |
| Safety Considerations | Use certified PA-free products to avoid liver toxicity | Generally safe when consumed in moderation |
Potential Health Benefits and Considerations
The beneficial compounds in borage may offer health advantages. The GLA in borage oil may help manage symptoms of rheumatoid arthritis by reducing joint pain and swelling. Borage oil's properties also make it useful in skincare for conditions like atopic dermatitis, potentially improving skin hydration and reducing inflammation.
In the kitchen, borage leaves and flowers have a mild, cucumber-like taste, suitable for salads, soups, and drinks. The blue flowers can also serve as edible garnishes.
Important Safety Information
Borage plants contain pyrrolizidine alkaloids (PAs), which can be toxic to the liver with excessive long-term consumption. For borage oil supplements, it is essential to choose products certified as PA-free. Certain groups, including those with liver conditions, pregnant or breastfeeding women, and individuals on specific medications, should be particularly cautious or avoid borage products. Always consult a healthcare provider before using borage supplements.
Conclusion
Borage is primarily noted for being exceptionally high in gamma-linolenic acid (GLA), particularly in its seed oil. The leaves and flowers provide a different set of nutrients, including vitamins and minerals. This diverse composition allows borage to be used for various purposes, from addressing inflammatory skin concerns with oil extracts to enhancing culinary dishes with fresh leaves. When using borage products, especially supplements, prioritizing certified PA-free options is vital for safety and to gain the benefits of this unique herb.
