Dyeberry Scientific Name: Bilberry Other Names: Airelle, European Blueberry, Huckleberry, Vaccinium myrtillus, Whortleberry, Wineberry What side effects should I watch for? Although no reports of major side effects from bilberry were found in the literature, other oral preparations that are high in tannin content have been associated with kidney or liver damage. Individuals with kidney or liver conditions should not take bilberry products. A case study of several people who regularly used large amounts of an oral product containing high levels of tannins for many years, found they had a higher incidence of tongue and lip cancer than expected. Cancers of the nose and esophagus may also be more likely in people who use large amounts of tannin-containing products for long amounts of time. << Back What interactions should I watch for? >>

In general, herbal products are not subject to review or approval by the U.S. Food and Drug Administration (FDA). They are not required to be standardized, meaning that the amounts of active ingredients or contaminants they contain may vary between brands or between different batches of the same brand. Not all of the risks, side effects, or interactions associated with the use of herbal products are known because few reliable studies of their use in humans have been done.
