Is Bilberry Safe in Breastfeeding

I am a breastfeeding mother and i want to know if it is safe to use Bilberry? Is Bilberry safe for nursing mother and child? Does Bilberry extracts into breast milk? Does Bilberry has any long term or short term side effects on infants? Can Bilberry influence milk supply or can Bilberry decrease milk supply in lactating mothers?

Bilberry (Vaccinium myrtillus) fruit contains tannins and anthocyanidins. Bilberry is most often used for eye disorders. Bilberry was reportedly used as a European folk medicine to stop milk flow. No data exist on the excretion of any components of bilberry into breastmilk or on the safety and efficacy of bilberry in nursing mothers or infants. Bilberry preparations are generally well tolerated as a food, but should be avoided in patients allergic to bilberry, cranberry, blueberry, and other Vaccinium species. No recommendations can be made on the use of large quantities of bilberry products during breastfeeding. Dietary supplements do not require pre-marketing approval from the U.S. Food and Drug Administration. Manufacturers are responsible to ensure the safety, but do not need to the safety and effectiveness of dietary supplements before they are marketed. Dietary supplements may contain multiple ingredients, and differences are often found between labeled and actual ingredients or their amounts. A manufacturer may contract with an independent organization to verify the quality of a product or its ingredients, but that does certify the safety or effectiveness of a product. Because of the above issues, clinical testing results on one product may not be applicable to other products.
