Dong Quai Other Names: Angelica polymorpha, Angelica sinensis, Chinese Angelica, Danggui, Tang-Kuei What side effects should I watch for? Major Side Effects Several of the chemicals found in dong quai have been shown to cause cancer in laboratory animals that were given very large amounts of them for long periods. No evidence from human studies documents this risk, however. Less Severe Side Effects Dong quai can make unprotected skin more sensitive to sunlight or artificial light used in tanning parlors. Individuals who use dong quai should be sure to use sunscreen, as well. One case has been reported of temporary breast enlargement in a man who took a combination product that contained dong quai. The exact cause of this breast enlargement is not known, but it is thought to have been due to contamination in the product being used. << Back What interactions should I watch for? >>

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.
