Borage Leaf
Borage leaf is a traditional plant used in food and folk herbalism, but it comes with an important safety note: borage leaf can contain pyrrolizidine alkaloids (PAs), which can be harmful to the liver in certain amounts or long-term use. Many people choose PA-free borage seed oil instead when seeking GLA-related benefits.
Key Benefits
- Traditional use for soothing and cooling support (historical/folk use)
- Used in some cultures as an edible green (small amounts)
- Borage seed oil (PA-free) is more commonly used for GLA support than leaf
Common Issues It May Help With
- Traditional ‘cooling’ support (non-specific)
- Skin comfort (more often via borage seed oil)
How To Use (Simple)
- If using leaf at all, keep it occasional and food-level only, and prefer sources that indicate low/PA-free where possible. For GLA goals, consider borage seed oil products that are certified PA-free and follow label directions.
Taste / Notes
Cucumber-like, green and mild (as a fresh leaf).
Evidence Level
Leaf evidence is limited; borage seed oil has more supportive evidence for specific uses due to GLA content, but outcomes vary.
Cautions
HIGH CAUTION: Avoid long-term use of borage leaf due to potential PA liver toxicity. Avoid in pregnancy/breastfeeding. Avoid if you have liver disease. Choose PA-free products if using borage-derived supplements.
Interactions
Avoid with hepatotoxic medications or heavy alcohol use (liver stress) If on anticoagulants, discuss borage seed oil with a clinician (theoretical bleeding risk at high doses) If on seizure medications, consult a clinician before using borage products
