Antibacterial Effect of Borage

The flowers and the leaves of borage are used medicinally in France as an antifebrile, anti-depressive, for the treatment of stress and of circulatory heart diseases, for pulmonary complaints, as a poultice for inflammatory swellings, as a diuretic (due to potassium nitrate), as a laxative, emollient and demulcent (due to the mucilage), and recently as a possible protective factor against cancer.


Iran Borage (Echium amoenum) is an annual plant of the Boraginaceae family, which grows in most of Europe and in northern Iran. Iranian borage is used in traditional medicine for infectious diseases, flu and as an anti-febrile.


The plant constituents have been isolated by different investigators; they include gamma-linolenic acid (GLA), alpha-linolenic acid (ALA), pyrrolizidine alkaloids, mucilage, resin, potassium nitrate, and calcium salt combined with mineral acids.


In 2004, an aqueous extract of dried borage flowers was tested in vitro for its antibacterial activity against Staphylococcus aureus 8327. Cold aqueous extract (pH 5.8) of dried E. amaenum flowers was used in all the experiments. Dried flowers (15 g) were steeped for 6 h at 4oCin 300 mL distilled water, with constant stirring. The extract showed concentration-dependent antibacterial activity against Staphylococcusa ureus 8327. This activity was heat resistant, but the activity of freeze-dried extract gradually diminished during a 90-day period. The traditional use of Iranian borage flowers for infectious diseases and for controlling fever appears to be justified.
