Borage flowers and herb contain tannins, soluble silicic acid and mucilage; used in folk medicine for inflammation of the respiratory tract, urinary retention and diarrhea. The content of liver-toxic pyrrolizidine alkaloids can be high; medicinal use is not recommended.

Externally: 10-20% of the oil can be added to appropriate ointment bases (e.g. Unguentum emulsificans). Indication: chronic eczema, atopic eczema

The pyrrazolidine alkaloids in the herb have a hepatotoxic and carcinogenic effect.
