Safety, Cautions & Contraindications

Safety note[14, 15, 16]Serious

Pyrrolizidine alkaloids (PAs): Many Boraginaceae can produce PAs; unsaturated PAs are hepatotoxic and genotoxic (risk increases with cumulative exposure). Borage as food/tea: PA presence in borage consumed as herb/tea has been specifically studied; EU has set PA maximum levels for certain foods including borage (context for why sourcing/limits matter). Pregnancy/breastfeeding: avoid internal use of borage herb products due to PA-related concerns and risk uncertainty. Liver disease / long-term use: avoid (PA risk + cumulative exposure logic). Seed oil vs herb: refined/quality-controlled seed oil is generally the preferred form when borage is used medicinally, because the main target compound is GLA; however, product quality and contamination control still matter. Drug interactions (caution): GLA oils have been discussed with anticoagulants (bleeding risk caution is better established for evening primrose oil; borage oil is often grouped in the same “GLA oil” category). Use caution if on anticoagulants/antiplatelets.

Safety note[14, 15, 16]Serious

Duke (2002) rates borage as a single-plus herb (+) with predominantly folklore-level evidence. Borage seed oil is rich in gamma-linolenic acid (GLA) and has been used for inflammatory conditions such as arthritis and PMS, and for cardiovascular support; typical dose is one 300 mg softgel containing 24% GLA or 2-4 ml liquid leaf extract. Commission E does not approve borage for any indication, and the herb contains hepatotoxic and carcinogenic pyrrolizidine alkaloids, making long-term use inadvisable (Duke, 2002).
