Borage

Borage (Borago officinalis), often called Starflower, is a humble herb with a mighty secret locked inside its seeds: one of the highest natural concentrations of Gamma-Linolenic Acid (GLA) found in nature. While the leaves and flowers have a long history in traditional cooking and herbal tea, the seed oil is where the real magic happens for modern health. GLA is an Omega-6 fatty acid, but unlike the inflammatory fats found in processed foods, Borage oil provides the building blocks your body needs to soothe inflammation, balance hormones, and keep skin glowing. Think of it as nature's anti-inflammatory powerhouse, offering a gentle yet effective way to support your body from the inside out.

Health Benefits & Sources

Why You Need It

  • Skin Health: Deeply hydrates and soothes inflammatory skin conditions like eczema and acne.
  • Hormonal Balance: Can significantly reduce the pain and inflammation associated with PMS and menopause.
  • Joint Support: Eases the stiffness and pain of rheumatoid arthritis.
  • Heart & Cell Health: Supports healthy cell membranes and regulates blood pressure.

Deep Dive

Your body can make GLA from other fats, but stress, age, and diet can make this process inefficient. Borage oil bypasses this bottleneck. It is converted into a hormone-like substance called prostaglandin E1 (PGE1). Think of PGE1 as your body's internal 'peacemaker'—it helps regulate the immune system, reduces swelling, and keeps blood vessels relaxed. For skin, this translates to less redness and better moisture retention. For women, it helps balance the ratio of estrogen and prolactin, smoothing out the emotional and physical rollercoaster of the menstrual cycle.

Natural Food Sources

Important Distinction: The leaves and flowers of the Borage plant are edible (tasting like cucumber) and used in salads or tea. However, they contain almost no GLA. The potent medicinal oil comes exclusively from the tiny seeds.

Food SourceAmount of GLA (per 100g)Notes
Borage Seed Oil17,000 - 26,000 mgThe most concentrated natural source.
Evening Primrose Oil9,000 mgThe closest competitor.
Black Currant Seed Oil15,000 mgExcellent alternative.
Hemp Seeds300 mgGood dietary source.

Supplementation

Since you would need to eat massive amounts of hemp seeds to get a therapeutic dose, Borage is almost exclusively taken as a softgel supplement.

  • Typical Dosage: 500mg to 2,000mg of Borage Oil daily.
  • Who Should Take It: Individuals with inflammatory skin conditions, women suffering from severe PMS or menopausal symptoms, and those with inflammatory joint pain.

Frequently Asked Questions

No, but they are both rich in GLA. Borage oil contains significantly more GLA (about 2-3 times more) than Evening Primrose oil, making it more potent per capsule.
Yes, the leaves are edible and taste like cucumber. However, do not rely on them for the medicinal GLA benefits; you need the seed oil for that.
For skin and hormonal issues, it typically takes 2 to 3 months of consistent daily use to notice significant improvements.
While sometimes used for ADHD or eczema in children, always consult a pediatrician before giving Borage oil to a child.

Safety & Side Effects

Safety Warning: Never consume raw Borage leaves in large quantities. They contain hepatotoxic pyrrolizidine alkaloids (PAs), which can damage the liver. Most commercial supplements are PA-free (look for 'PA-Free' on the label), but stick to regulated supplements rather than foraging.

Side Effects: Generally mild (upset stomach, loose stools).

Interactions: May slow blood clotting; avoid before surgery or if taking blood thinners like Warfarin.
