How does Bilberry work?

Bilberry contains chemicals called tannins that can help improve diarrhea, and mouth and throat irritation by reducing swelling (inflammation). There is some evidence that the chemicals found in bilberry leaves can help lower blood sugar and cholesterol levels.

Are there safety concerns?

The dried, ripe fruit of bilberry is safe for most people when eaten in typical food amounts. Bilberry fruit products, such as powders or extracts, also seem to be safe for most people.

Bilberry leaf probably isn't safe for most people when taken in high doses or for a long time. If you have diabetes, keep in mind that bilberry leaf might lower blood sugar. Monitor your blood sugar closely.

Do not use bilberry in medicinal amounts if:
  • You are pregnant or breast-feeding.
  • You are scheduled for surgery in the next two weeks.
