Natural health supplements sometimes have unexpected side effects or interactions with medication that can lead to adverse reactions that are sometimes life threatening. The following is a list of cautions that you should be aware of before using Borage Oil (Borago officinalis). These are referred to as drug/herb interactions.
Warning 1 - Contraindications: Pregnancy. Borage oil contains gamma-linolenic acid, which increases production of prostaglandin E, a compound that can stimulate premature labor.
Warning 2 - Contains pyrrolizidine alkaloids: Borage contains lycopsamine, amabiline, and thesinine. Used excessively these alkaloids are hepatoxic and may inflame or damage the liver.
Note: You can avoid the above complications by using Borage that is labeled "PA-free."
Warning 3 - Blood thinners: Borage oil has blood thinning effects and may increase the risk of bleeding if used with medications such as coumadin (Warfarin) or plavix (Clopidogrel).
Warning 4 - Anticonvulsants: Borage oil appears to interact with anticonvulsants lowing the seizure threshold.
Used as a natural health remedy: Borage Oil is used internally for eczema, as a diuretic, and antidiarrheal remedy.
