Bilberry is known as a remedy for improving eyesight. It has also been used to treat diarrhoea, ulcerative colitis and haemorrhoids and externally for inflammation of the mouth and mucous membranes. Some research also suggests that it is useful in venous insufficiency, peripheral vascular disorders (such as Raynaud's syndrome) and capillary fragility.
-
Traditional Use
Bilberry has been used as food for centuries due to its high nutritive value. Bilberry’s history of medicinal use dates back to the Middle Ages but it did not become widely known to herbalists until the 16th century when its use was documented for treating bladder stones, biliary disorders, scurvy, coughs and lung tuberculosis.

Use in Pregnancy
A theoretical risk exists that high doses (>170 mg anthocyanidins) may increase bleeding risk, however this remains uncertain as there is inadequate clinical evidence. Use with caution in people with haemorrhagic disorders.

Drug Interactions
